- Abstract
The third edition of Flow Cytometry Guidelines provides the key aspects to consider when performing flow cytometry experiments and includes comprehensive sections describing phenotypes and functional assays of all major human and murine immune cell subsets. Notably, the Guidelines contain helpful tables highlighting phenotypes and key differences between human and murine cells. Another useful feature of this edition is the flow cytometry analysis of clinical samples with examples of flow cytometry applications in the context of autoimmune diseases, cancers as well as acute and chronic infectious diseases. Furthermore, there are sections detailing tips, tricks and pitfalls to avoid. All sections are written and peer-reviewed by leading flow cytometry experts and immunologists, making this edition an essential and state-of-the-art handbook for basic and clinical researchers.

- Abstract
T follicular helper (Tfh) cells are crucial for the establishment of germinal centers (GCs) and potent antibody responses. Nevertheless, the T cell-intrinsic factors that are required for the maintenance of already-established Tfh cells and GCs remain largely unknown. Here, we use temporally guided gene ablation in CD4+ T cells to dissect the contributions of the Tfh-associated chemokine receptor CXCR5 and the transcription factor Bcl6. Induced ablation of Cxcr5 has minor effects on the function of established Tfh cells, and Cxcr5-ablated cells still exhibit most of the features of CXCR5+ Tfh cells. In contrast, continued Bcl6 expression is critical to maintain the GC Tfh cell phenotype and also the GC reaction. Importantly, Bcl6 ablation during acute viral infection results in the transdifferentiation of established Tfh into Th1 cells, thus highlighting the plasticity of Tfh cells. These findings have implications for strategies that boost or restrain Tfh cells and GCs in health and disease.

T follicular helper (Tfh) cells are critically involved in the establishment of potent antibody responses against infectious pathogens, such as viruses and bacteria, but their dysregulation may also result in aberrant antibody responses that frequently coincide with autoimmune diseases or allergies. The fate and identity of Tfh cells is tightly controlled by gene regulation on the transcriptional and posttranscriptional level. Here, we provide deeper insights into the posttranscriptional mechanisms that regulate Tfh cell differentiation, function, and plasticity through the actions of RNA-binding proteins (RBPs) and small endogenously expressed regulatory RNAs called microRNAs (miRNAs). The Roquin family of RBPs has been shown to dampen spontaneous activation and differentiation of naive CD4(+) T cells into Tfh cells, since CD4(+) T cells with Roquin mutations accumulate as Tfh cells and provide inappropriate B cell help in the production of autoantibodies. Moreover, Regnase-1, an endoribonuclease that regulates a set of targets, which strongly overlaps with that of Roquin, is crucial for the prevention of autoantibody production. Interestingly, both Roquin and Regnase-1 proteins are cleaved and inactivated after TCR stimulation by the paracaspase MALT1. miRNAs are expressed in naive CD4(+) T cells and help preventing spontaneous differentiation into effector cells. While most miRNAs are downregulated upon T cell activation, several miRNAs have been shown to regulate the fate of these cells by either promoting (e.g., miR-17-92 and miR-155) or inhibiting (e.g., miR-146a) Tfh cell differentiation. Together, these different aspects highlight a complex and dynamic regulatory network of posttranscriptional gene regulation in Tfh cells that may also be active in other T helper cell populations, including Th1, Th2, Th17, and Treg.

Follicular helper T cells (T FH cells) are the prototypic helper T cell subset specialized to enable B cells to form germinal centers (GCs) and produce high-affinity antibodies. We found that expression of microRNAs (miRNAs) by T cells was essential for T FH cell differentiation. More specifically, we show that after immunization of mice with protein, the miRNA cluster miR-17∼92 was critical for robust differentiation and function of T FH cells in a cell-intrinsic manner that occurred regardless of changes in proliferation. In a viral infection model, miR-17∼92 restrained the expression of genes 'inappropriate' to the T FH cell subset, including the direct miR-17∼92 target Rora. Removal of one Rora allele partially 'rescued' the inappropriate gene signature in miR-17∼92-deficient T FH cells. Our results identify the miR-17∼92 cluster as a critical regulator of T cell-dependent antibody responses, T FH cell differentiation and the fidelity of the T FH cell gene-expression program. © 2013 Nature America, Inc.

- Abstract
Common dendritic cell progenitors (CDPs) in the bone marrow (BM) regenerate dendritic cells (DCs) in lymphoid and nonlymphoid tissues. How the dissemination of progenitor-derived DCs to peripheral tissues is regulated on need remains elusive. Microbes are sensed by pathogen recognition receptors such as Toll-like receptors (TLRs). We found that CDPs in the BM express TLR2, TLR4, and TLR9. On TLR stimulation, CDPs down-regulated CXCR4, the nonredundant chemokine receptor for their BM retention, up-regulated CCR7, and migrated to lymph nodes (LNs). When TLR agonists were injected locally, CDPs preferentially gave rise to DCs in inflamed LNs in expense of noninflamed LNs and the BM, but they did not alter their lineage differentiation and proliferative activity. Consequently, BM DC progenitors can sense TLR agonists and, via regulation of CXCR4 and CCR7, support the replenishment of DCs in reactive LNs. This mechanism likely developed to support DC homeostasis on specific need at sites of inflammation.

Summary: T follicular helper (Tfh) cells are crucial for the establishment of germinal centers (GCs) and potent antibody responses. Nevertheless, the T cell-intrinsic factors that are required for the maintenance of already-established Tfh cells and GCs remain largely unknown. Here, we use temporally guided gene ablation in CD4+ T cells to dissect the contributions of the Tfh-associated chemokine receptor CXCR5 and the transcription factor Bcl6. Induced ablation of Cxcr5 has minor effects on the function of established Tfh cells, and Cxcr5-ablated cells still exhibit most of the features of CXCR5+ Tfh cells. In contrast, continued Bcl6 expression is critical to maintain the GC Tfh cell phenotype and also the GC reaction. Importantly, Bcl6 ablation during acute viral infection results in the transdifferentiation of established Tfh into Th1 cells, thus highlighting the plasticity of Tfh cells. These findings have implications for strategies that boost or restrain Tfh cells and GCs in health and disease.

- Abstract
Conventional dendritic cells (cDC) play key roles in immune induction, but what drives their heterogeneity and functional specialization is still ill-defined. Here we show that cDC-specific deletion of the transcriptional repressor Bcl6 in mice alters the phenotype and transcriptome of cDC1 and cDC2, while their lineage identity is preserved. Bcl6-deficient cDC1 are diminished in the periphery but maintain their ability to cross-present antigen to CD8
+ T cells, confirming general maintenance of this subset. Surprisingly, the absence of Bcl6 in cDC causes a complete loss of Notch2-dependent cDC2 in the spleen and intestinal lamina propria. DC-targeted Bcl6-deficient mice induced fewer T follicular helper cells despite a profound impact on T follicular regulatory cells in response to immunization and mounted diminished Th17 immunity to Citrobacter rodentium in the colon. Our findings establish Bcl6 as an essential transcription factor for subsets of cDC and add to our understanding of the transcriptional landscape underlying cDC heterogeneity., (© 2024.

- Abstract
T follicular helper (T
FH ) cells are essential for effective antibody responses, but deciphering the intrinsic wiring of mouse TFH cells has long been hampered by the lack of a reliable protocol for their generation in vitro. We report that transforming growth factor-β (TGF-β) induces robust expression of TFH hallmark molecules CXCR5 and Bcl6 in activated mouse CD4+ T cells in vitro. TGF-β-induced mouse CXCR5+ TFH cells are phenotypically, transcriptionally, and functionally similar to in vivo-generated TFH cells and provide critical help to B cells. The study further reveals that TGF-β-induced CXCR5 expression is independent of Bcl6 but requires the transcription factor c-Maf. Classical TGF-β-containing T helper 17 (TH 17)-inducing conditions also yield separate CXCR5+ and IL-17A-producing cells, highlighting shared and distinct cell fate trajectories of TFH and TH 17 cells. We demonstrate that excess IL-2 in high-density T cell cultures interferes with the TGF-β-induced TFH cell program, that TFH and TH 17 cells share a common developmental stage, and that c-Maf acts as a switch factor for TFH versus TH 17 cell fates in TGF-β-rich environments in vitro and in vivo.- Published

- Abstract
Autoreactive encephalitogenic T cells exist in the healthy immune repertoire but need a trigger to induce CNS inflammation. The underlying mechanisms remain elusive, whereby microbiota were shown to be involved in the manifestation of CNS autoimmunity. Here, we used intravital imaging to explore how microbiota affect the T cells as trigger of CNS inflammation. Encephalitogenic CD4
+ T cells transduced with the calcium-sensing protein Twitch-2B showed calcium signaling with higher frequency than polyclonal T cells in the small intestinal lamina propria (LP) but not in Peyer's patches. Interestingly, nonencephalitogenic T cells specific for OVA and LCMV also showed calcium signaling in the LP, indicating a general stimulating effect of microbiota. The observed calcium signaling was microbiota and MHC class II dependent as it was significantly reduced in germfree animals and after administration of anti-MHC class II antibody, respectively. As a consequence of T cell stimulation in the small intestine, the encephalitogenic T cells start expressing Th17-axis genes. Finally, we show the migration of CD4+ T cells from the small intestine into the CNS. In summary, our direct in vivo visualization revealed that microbiota induced T cell activation in the LP, which directed T cells to adopt a Th17-like phenotype as a trigger of CNS inflammation.- Published

- Abstract
The magnitude and quality of the germinal center (GC) response decline with age, resulting in poor vaccine-induced immunity in older individuals. A functional GC requires the co-ordination of multiple cell types across time and space, in particular across its two functionally distinct compartments: the light and dark zones. In aged mice, there is CXCR4-mediated mislocalization of T follicular helper (T
FH ) cells to the dark zone and a compressed network of follicular dendritic cells (FDCs) in the light zone. Here we show that TFH cell localization is critical for the quality of the antibody response and for the expansion of the FDC network upon immunization. The smaller GC and compressed FDC network in aged mice were corrected by provision of TFH cells that colocalize with FDCs using CXCR5. This demonstrates that the age-dependent defects in the GC response are reversible and shows that TFH cells support stromal cell responses to vaccines., (© 2023. The Author(s).)- Published

- Abstract
Activation of immune cells is an essential process in innate and adaptive immunity. A high number of immune cell activation pathways have been discovered, which are stimulated via various intra- and extracellular receptors. Small-molecule and macromolecular agonists have been identified to target immune receptors in preclinical research and clinical practice. However, current immunostimulants are often associated with undesired side effects and/or low potency in vivo. These two issues have been addressed with multiscale biomaterials. In this review, we summarize and discuss the most explored intra/extracellular immune receptors which have been targeted with immunoactivating biomaterials. To target intracellular immune receptors, nano/microscale materials have been employed to deliver agonists into the endo/lysosomes or the cytoplasm. To target surface immune receptors, nano-to-macroscale biomaterials have been engineered to engage with them to activate immune cells. In this context, biomaterials are not only the drug carriers, but also function as part of the immunostimulants. The biomaterials-based modalities have shown clearly enhanced immunoactivation potency and decreased side effects compared to native immunostimulants. It is envisaged that nano-to-macroscale biomaterials will greatly contribute to the development of more effective strategies for immunoactivation, which have the potential to reshape future vaccination and immunotherapy., (Copyright © 2023 Elsevier B.V.

- Abstract
T follicular helper (Tfh) cells provide essential help to B cells for effective antibody-mediated immune responses. Although the crucial function of these CD4
+ T cells in infection and vaccination is well established, their involvement in cancer is only beginning to emerge. Increased numbers of Tfh cells in Tfh cell-derived or B cell-associated malignancies are often associated with an unfavorable outcome, whereas in various solid organ tumor types of non-lymphocytic origin, their presence frequently coincides with a better prognosis. We discuss recent advances in understanding how Tfh cell crosstalk with B cells and CD8+ T cells in secondary and tertiary lymphoid structures (TLS) enhances antitumor immunity, but may also exacerbate immune-related adverse events (irAEs) such as autoimmunity during immune checkpoint blockade (ICB) and cancer immunotherapy., Competing Interests: Declaration of interests The authors declare no conflicts of interest., (Copyright © 2022 The Author(s).

- Abstract
Research on the human immune system is often restricted to peripheral blood cells. However, these cells can be different from those found in secondary lymphoid organs. For instance, specialized T and B cells that are localized in germinal centers (GCs), which are complex anatomical structures being required for the generation of potent antibodies, are not found in peripheral blood. Most T helper cells located in GCs belong to the T follicular helper (Tfh) cell subset, which provides critical support to B cells. Bona fide human GC Tfh cells can be obtained from secondary lymphoid tissues such as tonsils, which are routinely removed by surgery. We here describe a method that is based on human lymphoid histoculture (HLH) and human lymphoid aggregate culture (HLAC) to culture human adenoid (pharyngeal tonsil) tissue ex vivo, followed by deep Tfh cell phenotyping by flow cytometry. This method allows studying Tfh cells in a versatile explant culture system that preserves many aspects of the original in vivo three-dimensional (3D) structure, in parallel to single-cell suspension organoid cultures in which the original tissue structure is disintegrated. We also describe how this versatile platform can be used for drug testing or manipulation of human Tfh cells in vitro for mechanistic studies., (© 2022.

- Abstract
Disease manifestations in COVID-19 range from mild to severe illness associated with a dysregulated innate immune response. Alterations in function and regeneration of dendritic cells (DCs) and monocytes may contribute to immunopathology and influence adaptive immune responses in COVID-19 patients. We analyzed circulating DC and monocyte subsets in 65 hospitalized COVID-19 patients with mild/moderate or severe disease from acute illness to recovery and in healthy controls. Persisting reduction of all DC subpopulations was accompanied by an expansion of proliferating Lineage-HLADR+ cells lacking DC markers. Increased frequency of CD163+ CD14+ cells within the recently discovered DC3 subpopulation in patients with more severe disease was associated with systemic inflammation, activated T follicular helper cells, and antibody-secreting cells. Persistent downregulation of CD86 and upregulation of programmed death-ligand 1 (PD-L1) in conventional DCs (cDC2 and DC3) and classical monocytes associated with a reduced capacity to stimulate naïve CD4+ T cells correlated with disease severity. Long-lasting depletion and functional impairment of DCs and monocytes may have consequences for susceptibility to secondary infections and therapy of COVID-19 patients., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Post-transcriptional gene regulation in T cells is dynamic and complex as targeted transcripts respond to various factors. This is evident for the Icos mRNA encoding an essential costimulatory receptor that is regulated by several RNA-binding proteins (RBP), including Roquin-1 and Roquin-2. Here, we identify a core RBPome of 798 mouse and 801 human T cell proteins by utilizing global RNA interactome capture (RNA-IC) and orthogonal organic phase separation (OOPS). The RBPome includes Stat1, Stat4 and Vav1 proteins suggesting unexpected functions for these transcription factors and signal transducers. Based on proximity to Roquin-1, we select ~50 RBPs for testing coregulation of Roquin-1/2 targets by induced expression in wild-type or Roquin-1/2-deficient T cells. Besides Roquin-independent contributions from Rbms1 and Cpeb4 we also show Roquin-1/2-dependent and target-specific coregulation of Icos by Celf1 and Igf2bp3. Connecting the cellular RBPome in a post-transcriptional context, we find contributions from multiple RBPs to the prototypic regulation of mRNA targets by individual trans-acting factors., (© 2021.

- Abstract
Peripheral nerve injury can cause debilitating disease and immune cell-mediated destruction of the affected nerve. While the focus has been on the nerve-regenerative response, the effect of loss of innervation on lymph node function is unclear. Here, we show that the popliteal lymph node (popLN) receives direct neural input from the sciatic nerve and that sciatic denervation causes lymph node expansion. Loss of sympathetic, adrenergic tone induces the expression of IFN-γ in LN CD8 T cells, which is responsible for LN expansion. Surgery-induced IFN-γ expression and expansion can be rescued by β2 adrenergic receptor agonists but not sensory nerve agonists. These data demonstrate the mechanisms governing the pro-inflammatory effect of loss of direct adrenergic input on lymph node function., Competing Interests: Disclosures: B.

- Abstract
T follicular helper (Tfh) cells cognately guide differentiation of antigen-primed B cells in secondary lymphoid tissues. 'Tfh-like' populations not expressing the canonical Tfh cell transcription factor BCL6 have also been described, which can aid particular aspects of B cell differentiation. Tfh and Tfh-like cells are essential for protective and pathological humoral immunity. These CD4
+ T cells that help B cells are polarized to produce diverse combinations of cytokines and chemokine receptors and can be grouped into distinct subsets that promote antibodies of different isotype, affinity, and duration, according to the nature of immune challenge. However, unified nomenclature to describe the distinct functional Tfh and Tfh-like cells does not exist. While explicitly acknowledging cellular plasticity, we propose categorizing these cell states into three groups based on phenotype and function, paired with their anatomical site of action., Competing Interests: Declaration of interests No interests are declared., (Copyright © 2021 Elsevier Ltd.

- Abstract
Cancer immunotherapy utilizing immune checkpoint inhibitors (ICIs) has revolutionized the treatment of numerous cancer types. As the underlying mechanism of these treatments lies in the interference with inhibitory signals that usually impair potent antitumor immunity, for example, cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and the programmed cell death protein 1 (PD-1):programmed death-ligand 1/2 (PD-L1/2) pathway, it is not surprising that this could also promote exaggerated adaptive immune responses to unrelated antigen specificities. One of the side effects of ICI-based cancer immunotherapy that is increasingly observed in the clinic is immune-related adverse events (irAEs), including various types of autoimmunity. However, the precise etiology is incompletely understood. T follicular helper (Tfh) cells provide essential help to B cells for potent antibody responses and their tumor tissue presence is often correlated with a better outcome in several solid tumor entities. Importantly, these CD4
+ T cells express very high amounts of PD-1 and other co-stimulatory and inhibitory receptors. Here, we address the hypothesis that targeting CTLA-4 or PD-1 and its ligand PD-L1 critically impacts the function of Tfh cells in patients that receive these ICIs, thereby providing a link between ICI treatment and the development of secondary autoimmunity., Competing Interests: Competing interests: DB reports grants and personal fees from Sanofi, and grants from Novartis, outside the submitted work; PB reports grants and personal fees from BMS, and personal fees from AstraZeneca, Amgen and MSD, outside the submitted work., (© Author(s) (or their employer(s)) 2021.

- Abstract
T follicular helper (Tfh) cells play an essential role in regulating the GC reaction and, consequently, the generation of high-affinity antibodies and memory B cells. Therefore, Tfh cells are critical for potent humoral immune responses against various pathogens and their dysregulation has been linked to autoimmunity and cancer. Tfh cell differentiation is a multistep process, in which cognate interactions with different APC types, costimulatory and coinhibitory pathways, as well as cytokines are involved. However, it is still not fully understood how a subset of activated CD4
+ T cells begins to express the Tfh cell-defining chemokine receptor CXCR5 during the early stage of the immune response, how some CXCR5+ pre-Tfh cells enter the B-cell follicles and mature further into GC Tfh cells, and how Tfh cells are maintained in the memory compartment. In this review, we discuss recent advances on how antigen and cognate interactions are important for Tfh cell differentiation and long-term persistence of Tfh cell memory, and how this is relevant to the current understanding of COVID-19 pathogenesis and the development of potent SARS-CoV-2 vaccines., (© 2021 The Authors.

- Abstract
Constitutive T cell-intrinsic miRNA expression is required for the differentiation of naïve CD4
+ T cells into Tfh cells, thus making it difficult to study the role of miRNAs in the maintenance of already established Tfh cells and ongoing germinal center (GC) responses. To overcome this problem, we here used temporally controlled ablation of mature miRNAs specifically in CD4+ T cells during acute LCMV infection in mice. T cell-intrinsic miRNA expression was not only critical at early stages of Tfh cell differentiation, but also important for the maintenance of already established Tfh cells. In addition, CD4+ T cell-specific ablation of miRNAs resulted in impaired GC B cell responses. Notably, miRNA deficiency also compromised the antigen-specific CD4+ T cell compartment, Th1 cells, Treg cells, and Tfr cells. In conclusion, our results highlight miRNAs as important regulators of Tfh cells, thus providing novel insights into the molecular events that govern T cell-B cell interactions and Th cell identity., (© 2020 The Authors.

- Abstract
T follicular helper (Tfh) cells are crucial for the establishment of germinal centers (GCs) and potent antibody responses. Nevertheless, the T cell-intrinsic factors that are required for the maintenance of already-established Tfh cells and GCs remain largely unknown. Here, we use temporally guided gene ablation in CD4
+ T cells to dissect the contributions of the Tfh-associated chemokine receptor CXCR5 and the transcription factor Bcl6. Induced ablation of Cxcr5 has minor effects on the function of established Tfh cells, and Cxcr5-ablated cells still exhibit most of the features of CXCR5+ Tfh cells. In contrast, continued Bcl6 expression is critical to maintain the GC Tfh cell phenotype and also the GC reaction. Importantly, Bcl6 ablation during acute viral infection results in the transdifferentiation of established Tfh into Th1 cells, thus highlighting the plasticity of Tfh cells. These findings have implications for strategies that boost or restrain Tfh cells and GCs in health and disease., Competing Interests: Declaration of Interests The authors declare no competing interests., (Copyright © 2020 The Authors.

- Abstract
Th cells integrate signals from their microenvironment to acquire distinct specialization programs for efficient clearance of diverse pathogens or for immunotolerance. Ionic signals have recently been demonstrated to affect T cell polarization and function. Sodium chloride (NaCl) was proposed to accumulate in peripheral tissues upon dietary intake and to promote autoimmunity via the Th17 cell axis. Here, we demonstrate that high-NaCl conditions induced a stable, pathogen-specific, antiinflammatory Th17 cell fate in human T cells in vitro. The p38/MAPK pathway, involving NFAT5 and SGK1, regulated FoxP3 and IL-17A expression in high-NaCl conditions. The NaCl-induced acquisition of an antiinflammatory Th17 cell fate was confirmed in vivo in an experimental autoimmune encephalomyelitis (EAE) mouse model, which demonstrated strongly reduced disease symptoms upon transfer of T cells polarized in high-NaCl conditions. However, NaCl was coopted to promote murine and human Th17 cell pathogenicity, if T cell stimulation occurred in a proinflammatory and TGF-β-low cytokine microenvironment. Taken together, our findings reveal a context-dependent, dichotomous role for NaCl in shaping Th17 cell pathogenicity. NaCl might therefore prove beneficial for the treatment of chronic inflammatory diseases in combination with cytokine-blocking drugs.

- Abstract
Objectives: T follicular helper (Tfh) cells are the principal T helper cell subset that provides help to B cells for potent antibody responses against various pathogens. In this study, we took advantage of the live-attenuated yellow fever virus (YFV) vaccine strain, YF-17D, as a model system for studying human antiviral immune responses in vivo following exposure to an acute primary virus challenge under safe and highly controlled conditions, to comprehensively analyse the dynamics of circulating Tfh (cTfh) cells., Methods: We tracked and analysed the response of cTfh and other T and B cell subsets in peripheral blood of healthy volunteers by flow cytometry over the course of 4 weeks after YF-17D vaccination., Results: Using surface staining of cell activation markers to track YFV-specific T cells, we found increasing cTfh cell frequencies starting at day 3 and peaking around 2 weeks after YF-17D vaccination. This kinetic was confirmed in a subgroup of donors using MHC multimer staining for four known MHC class II epitopes of YF-17D. The subset composition of cTfh cells changed dynamically during the course of the immune response and was dominated by the cTfh1-polarised subpopulation. Importantly, frequencies of cTfh1 cells correlated with the strength of the neutralising antibody response, whereas frequencies of cTfh17 cells were inversely correlated., Conclusion: In summary, we describe detailed cTfh kinetics during YF-17D vaccination. Our results suggest that cTfh expansion and polarisation can serve as a prognostic marker for vaccine success. These insights may be leveraged in the future to improve current vaccine design and strategies., Competing Interests: The authors declare no conflict of interest., (© 2020 The Authors.

- Abstract
A growing body of evidence suggests that Cre recombinase can be toxic to immune cells in various experimental settings. Cre recombinase toxicity is dependent on the level of Cre activity and may also interfere with cell proliferation. Here, we compared two different published tamoxifen-inducible CD4-CreERT2 mouse lines for their suitability to study the dynamics of T-follicular helper cell responses in vivo. Our data underscore that under certain circumstances inducible Cre toxicity (tamoxifen application results in translocation of preformed CreERT2 to the nucleus) interferes with cell survival and, therefore, necessitates careful interpretation of experimental data and the inclusion of appropriate controls. Interestingly, our data indicate that low expression of CreERT2 can still allow for efficient recombination in proliferating lymphocytes without causing excessive cell loss due to Cre toxicity., (© 2020 The Authors.

- Abstract
Fingolimod is an effective treatment for relapsing-remitting multiple sclerosis. It is well established that fingolimod, a modulator of the sphingosine-1-phosphate pathway, restrains the egress of CCR7
+ lymphocytes from lymphatic tissues into the blood, thus resulting in reduced lymphocyte counts in peripheral blood. CXCR5+ T follicular helper (Tfh) cells provide help to B cells, are essential for the generation of potent Ab responses, and have been shown to be critically involved in the pathogenesis of several autoimmune diseases. Besides lymphoid tissue-resident Tfh cells, CXCR5+ circulating Tfh (cTfh) cells have been described in the blood, their numbers correlating with the magnitude of Tfh cells in lymphoid tissues. Although the effect of fingolimod on circulating lymphocyte subsets has been established, its effect on cTfh cells remains poorly understood. In this study, we found that although fingolimod strongly and disproportionally reduced cTfh cell frequencies, frequencies of activated cTfh cells were increased, and the composition of the cTfh cell pool was skewed toward a cTfh1 cell phenotype. The circulating T follicular regulatory cell subset and CXCR5+ CD8+ T cell frequencies were also strongly and disproportionally decreased after fingolimod treatment. In contrast, relative frequencies of CXCR5- memory Th cells as well as regulatory T and B cells were increased. In summary, these data provide new insights into fingolimod-induced compositional changes of lymphocyte populations in the blood, in particular cTfh cells, and thus contribute to a better understanding of the mechanism of action of fingolimod in multiple sclerosis patients., (Copyright © 2020 by The American Association of Immunologists, Inc.)- Published

- Abstract
Background: Human immunology research is often limited to peripheral blood. However, there are important differences between blood immune cells and their counterparts residing in secondary lymphoid organs, such as in the case of germinal center (GC) T follicular helper (Tfh) cells and GC B cells., Methods: We developed a versatile ex vivo lymphoid organ culture platform that is based on human pharyngeal tonsils (adenoids) and allows for drug testing. We systematically phenotyped Tfh and GC B cell subsets in explant- and suspension cultures using multicolor flow cytometry and cytokine multiplex analysis., Findings: Phenotypic changes of certain ex vivo cultured immune cell subsets could be modulated by cytokine addition. Furthermore, we optimized an activation-induced marker assay to evaluate the response to T cell stimulation. We provide proof-of-concept that Tfh and GC B cells could be modulated in these cultures by different anti-inflammatory drugs in unstimulated states and upon activation with vaccine-derived antigens. For example, GC B cells were lost upon CD40L blockade, and clinically approved JAK inhibitors impacted Tfh and GC B cells, including down-regulation of their key transcription factor BCL6. BCL6 regulation was affected by IL-6 signaling in T cells and IL-4 in B cells, respectively. Furthermore, we demonstrated that JAK signaling and TNF signaling contributed to the stimulation-induced activation of tonsil-derived T cells., Interpretation: Our optimized methods, assays, and mechanistic findings can contribute to a better understanding of human GC responses. These insights may be relevant for improving autoimmune disease therapy and vaccination efficacy., Funding: This work was supported by a project grant under the joint research cooperation agreement of LMU Munich, LMU University Hospital, and Sanofi-Aventis Deutschland GmbH, as well as by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) - Emmy Noether Programme BA 5132/1-1 and BA 5132/1-2 (252623821), SFB 1054 Project B12 (210592381), and SFB 914 Project B03 (165054336)., (Copyright © 2020 The Authors.

- Abstract
T follicular helper (Tfh) cells are critical mediators of germinal center (GC) formation and essential for potent humoral immunity. In contrast, T follicular regulatory (Tfr) cells, which share characteristics of both stimulatory Tfh cells and suppressive regulatory T (Treg) cells, restrain excessive GC responses. Tfh cell differentiation is a multistep process that involves continuous interaction with antigen-presenting cells, co-stimulatory signals, an appropriate cytokine milieu, and directed migration toward distinct microanatomical structures. These processes are under the control of several intrinsic and extrinsic regulatory layers that further undergo fine-tuning by post-transcriptional mechanisms. MicroRNAs (miRNAs) are small, non-coding RNAs that have been recognized as important post-transcriptional regulators. miRNAs are particularly critical for Tfh cell generation, as the differentiation of these cells is completely blocked in the absence of mature miRNAs in vivo. Here, we discuss how miRNAs regulate various aspects of Tfh and Tfr cell differentiation and function and how miRNAs thus shape the identity of these cells., (© 2019 John Wiley & Sons A/S.

- Abstract
The incidence of allergic diseases has increased over the past 50 years, likely due to environmental factors. However, the nature of these factors and the mode of action by which they induce the type 2 immune deviation characteristic of atopic diseases remain unclear. It has previously been reported that dietary sodium chloride promotes the polarization of T helper 17 (T
H 17) cells with implications for autoimmune diseases such as multiple sclerosis. Here, we demonstrate that sodium chloride also potently promotes TH 2 cell responses on multiple regulatory levels. Sodium chloride enhanced interleukin-4 (IL-4) and IL-13 production while suppressing interferon-γ (IFN-γ) production in memory T cells. It diverted alternative T cell fates into the TH 2 cell phenotype and also induced de novo TH 2 cell polarization from naïve T cell precursors. Mechanistically, sodium chloride exerted its effects via the osmosensitive transcription factor NFAT5 and the kinase SGK-1, which regulated TH 2 signature cytokines and master transcription factors in hyperosmolar salt conditions. The skin of patients suffering from atopic dermatitis contained elevated sodium compared to nonlesional atopic and healthy skin. These results suggest that sodium chloride represents a so far overlooked cutaneous microenvironmental checkpoint in atopic dermatitis that can induce TH 2 cell responses, the orchestrators of atopic diseases., (Copyright © 2019 The Authors, some rights reserved; exclusive licensee American Association for the Advancement of Science.

- Abstract
T helper (Th) cells are critically involved in adaptive immune responses against various pathogens. In contrast, dysregulated T helper cell responses are associated with a variety of diseases, including autoimmunity, allergies, and cancer. Differentiation of naïve CD4
+ T cells into effector T helper cell subsets, including Th1, Th2, Th17, Treg, and T follicular helper (Tfh), requires precise dosing of signaling molecules and transcription factors. MicroRNAs (miRNAs), which are small endogenously expressed RNAs that regulate gene expression, play important roles in these processes. The miR-17-92 cluster, a miRNA polycistron also known as oncomiR-1, has emerged as a central integrator of gene expression events that govern T helper cell differentiation pathways. The complexity of miR-17-92-mediated gene regulation lies in the nature of this miRNA cluster, which consists of six different miRNAs. Individual miR-17-92 miRNAs, albeit initially transcribed as one transcript, can have cooperative or opposing effects on biological processes. Therefore, a better understanding of the molecular regulation of miR-17-92 and its downstream networks will provide important insights into T helper cell differentiation and diversity that may be harnessed for the design of advanced T cell-targeting therapies., (Copyright © 2018 Elsevier B.V.

- Abstract
Roquin proteins preclude spontaneous T cell activation and aberrant differentiation of T follicular helper (Tfh) or T helper 17 (Th17) cells. Here we showed that deletion of Roquin-encoding alleles specifically in regulatory T (Treg) cells also caused the activation of conventional T cells. Roquin-deficient Treg cells downregulated CD25, acquired a follicular Treg (Tfr) cell phenotype, and suppressed germinal center reactions but could not protect from colitis. Roquin inhibited the PI3K-mTOR signaling pathway by upregulation of Pten through interfering with miR-17∼92 binding to an overlapping cis-element in the Pten 3' UTR, and downregulated the Foxo1-specific E3 ubiquitin ligase Itch. Loss of Roquin enhanced Akt-mTOR signaling and protein synthesis, whereas inhibition of PI3K or mTOR in Roquin-deficient T cells corrected enhanced Tfh and Th17 or reduced iTreg cell differentiation. Thereby, Roquin-mediated control of PI3K-mTOR signaling prevents autoimmunity by restraining activation and differentiation of conventional T cells and specialization of Treg cells., (Copyright © 2017 Elsevier Inc.

- Abstract
MicroRNAs (miRNAs) exert powerful effects on immunity through coordinate regulation of multiple target genes in a wide variety of cells. Type 2 innate lymphoid cells (ILC2s) are tissue sentinel mediators of allergic inflammation. We established the physiological requirements for miRNAs in ILC2 homeostasis and immune function and compared the global miRNA repertoire of resting and activated ILC2s and T helper type 2 (T
H 2) cells. After exposure to the natural allergen papain, mice selectively lacking the miR-17∼92 cluster in ILC2s displayed reduced lung inflammation. Moreover, miR-17∼92-deficient ILC2s exhibited defective growth and cytokine expression in response to IL-33 and thymic stromal lymphopoietin in vitro. The miR-17∼92 cluster member miR-19a promoted IL-13 and IL-5 production and inhibited expression of several targets, including SOCS1 and A20, signaling inhibitors that limit IL-13 and IL-5 production. These findings establish miRNAs as important regulators of ILC2 biology, reveal overlapping but nonidentical miRNA-regulated gene expression networks in ILC2s and TH 2 cells, and reinforce the therapeutic potential of targeting miR-19 to alleviate pathogenic allergic responses., (© 2017 Singh et al.)- Published

- Abstract
Th17 cell responses orchestrate immunity against extracellular pathogens but also underlie autoimmune disease pathogenesis. In this study, we uncovered a distinct and critical role for miR-18a in limiting Th17 cell differentiation. miR-18a was the most dynamically upregulated microRNA of the miR-17-92 cluster in activated T cells. miR-18a deficiency enhanced CCR6
+ RAR-related orphan receptor (ROR)γt+ Th17 cell differentiation in vitro and increased the number of tissue Th17 cells expressing CCR6, RORγt, and IL-17A in airway inflammation models in vivo. Sequence-specific miR-18 inhibitors increased CCR6 and RORγt expression in mouse and human CD4+ T cells, revealing functional conservation. miR-18a directly targeted Smad4 , Hif1a , and Rora , all key transcription factors in the Th17 cell gene-expression program. These findings indicate that activating signals influence the outcome of Th cell differentiation via differential regulation of mature microRNAs within a common cluster., (Copyright © 2017 by The American Association of Immunologists, Inc.)- Published

- Abstract
Cell-to-cell transmission of protein aggregates is an emerging theme in neurodegenerative disease. Here, we analyze the dipeptide repeat (DPR) proteins that form neuronal inclusions in patients with hexanucleotide repeat expansion C9orf72 , the most common known cause of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD). Sense and antisense transcripts of the (G4C2)
n repeat are translated by repeat-associated non-ATG (RAN) translation in all reading frames into five aggregating DPR proteins. We show that the hydrophobic DPR proteins poly-GA, poly-GP, and poly-PA are transmitted between cells using co-culture assays and cell extracts. Moreover, uptake or expression of poly-GA induces nuclear RNA foci in (G4C2)80 -expressing cells and patient fibroblasts, suggesting an unexpected positive feedback loop. Exposure to recombinant poly-GA and cerebellar extracts of C9orf72 patients increases repeat RNA levels and seeds aggregation of all DPR proteins in receiver cells expressing (G4C2)80 Treatment with anti-GA antibodies inhibits intracellular poly-GA aggregation and blocks the seeding activity of C9orf72 brain extracts. Poly-GA-directed immunotherapy may thus reduce DPR aggregation and disease progression in C9orf72 ALS/FTD., (© 2017 The Authors. Published under the terms of the CC BY 4.0 license.)- Published

- Abstract
CD4(+) Th17 are heterogeneous in terms of cytokine production and capacity to initiate autoimmune diseases, such as experimental autoimmune encephalomyelitis (EAE). Here we demonstrate that experimental priming of encephalitogenic Th cells expressing RORγt and T-bet and producing IL-17A, IFN-γ and GM-CSF but not IL-10 (Th1/Th17), is dependent on the presence of pertussis toxin (PTX) at the time of immunization. PTX induces early production of IL-1β by CD11b(+)CCR2(+)Gr1(+) myeloid cells, which are rapidly recruited to antigen-draining lymph nodes. PTX-induced generation of Th1/Th17 cells is impaired in IL-1β- and ASC-deficient mice and in mice in which myeloid cells are depleted or fail to migrate to lymph nodes and requires expression of IL-1R1 and MyD88 on both T cells and non-T cells. Collectively, these data shed light on the enigmatic function of PTX in EAE induction and suggest that inflammatory monocytes and microbial infection can influence differentiation of pathogenic Th1/Th17 cells in autoimmune diseases through production of IL-1β.

- Abstract
T follicular helper (Tfh) cells are essential for the formation of germinal centers (GCs) and the development of long-lived humoral immunity. Tfh cell differentiation is a multistep process driven by the balanced expression of key transcription factors that form a regulatory network in which small changes in gene expression determine the Tfh cell fate decision. Here, we review recent findings that have revealed that certain microRNAs act as important mediators within this network, with roles in tuning gene expression. We integrate these findings into the current understanding of the mechanisms governing T helper cell differentiation, and propose a model in which the establishment of Tfh cell identity is dependent on the differential expression and concerted action of distinct microRNAs and transcription factors., (Copyright © 2016 Elsevier Ltd.

- Abstract
We previously reported that Cd3e-deficient mice adoptively transferred with CD4(+) T cells generate high numbers of T follicular helper (Tfh) cells, which go on to induce a strong B-cell and germinal center (GC) reaction. Here, we show that in this system, GC B cells display an altered distribution between the dark and light zones, and express low levels of activation-induced cytidine deaminase. Furthermore, GC B cells from Cd3e(-/-) mice accumulate fewer somatic mutations as compared with GC B cells from wild-type mice, and exhibit impaired affinity maturation and reduced differentiation into long-lived plasma cells. Reconstitution of Cd3e(-/-) mice with regulatory T (Treg) cells restored Tfh-cell numbers, GC B-cell numbers and B-cell distribution within dark and light zones, and the rate of antibody somatic mutations. Tfh-cell numbers and GC B-cell numbers and dynamics were also restored by pre-reconstitution of Cd3e(-/-) mice with Cxcr5(-/-) Treg cells or non-regulatory, memory CD4(+) T cells. Taken together, these findings underline the importance of a quantitatively regulated Tfh-cell response for an efficient and long-lasting serological response., (© 2015 The Authors.

- Abstract
Studying 830 pre-B ALL cases from four clinical trials, we found that human ALL can be divided into two fundamentally distinct subtypes based on pre-BCR function. While absent in the majority of ALL cases, tonic pre-BCR signaling was found in 112 cases (13.5%). In these cases, tonic pre-BCR signaling induced activation of BCL6, which in turn increased pre-BCR signaling output at the transcriptional level. Interestingly, inhibition of pre-BCR-related tyrosine kinases reduced constitutive BCL6 expression and selectively killed patient-derived pre-BCR(+) ALL cells. These findings identify a genetically and phenotypically distinct subset of human ALL that critically depends on tonic pre-BCR signaling. In vivo treatment studies suggested that pre-BCR tyrosine kinase inhibitors are useful for the treatment of patients with pre-BCR(+) ALL., (Copyright © 2015 Elsevier Inc. All rights reserved.)

- Abstract
T follicular helper (Tfh) cells provide essential help to B cells for the generation of high-affinity antibodies. These mechanisms provide the basis for the success of modern vaccines, but dysregulated Tfh cell responses are also linked to autoimmune diseases. In addition to their established role in driving humoral immunity, Tfh cells are gaining attention for their role in other processes of the adaptive immune system. For example, Tfh cells may serve as transitional differentiation intermediates during effector and memory T-helper cell differentiation and as a reservoir of HIV-infected cells. While B cells are required for the full maturation and maintenance of Tfh cell responses, they are dispensable for the initial induction of the Tfh cell phenotype, which occurs at the priming stage through interaction with dendritic cells. Nevertheless, the precise mechanisms of these early events during Tfh cell differentiation remain relatively unknown. Here, we describe a method for tracking early Tfh cell differentiation by following cell division kinetics and phenotypic changes of recently activated antigen-specific CD4(+) T cells in vivo. As an example, we use this method to visualize the requirements for T cell-expressed CD28 for the differentiation of CXCR5(+)Bcl6(+) Tfh cells.

- Abstract
MicroRNAs (miRNAs) exert powerful effects on immunological function by tuning networks of target genes that orchestrate cell activity. We sought to identify miRNAs and miRNA-regulated pathways that control the type 2 helper T cell (TH2 cell) responses that drive pathogenic inflammation in asthma. Profiling miRNA expression in human airway-infiltrating T cells revealed elevated expression of the miRNA miR-19a in asthma. Modulating miR-19 activity altered TH2 cytokine production in both human and mouse T cells, and TH2 cell responses were markedly impaired in cells lacking the entire miR-17∼92 cluster. miR-19 promoted TH2 cytokine production and amplified inflammatory signaling by direct targeting of the inositol phosphatase PTEN, the signaling inhibitor SOCS1 and the deubiquitinase A20. Thus, upregulation of miR-19a in asthma may be an indicator and a cause of increased TH2 cytokine production in the airways.

- Abstract
The generation of germinal centers (GCs) is a hallmark feature of the adaptive immune response, resulting in the production of high-affinity antibodies that neutralize pathogens and confer protection upon reinfection. The GC response requires interactions between different immune cell types, and the coordination of complex and dynamic gene expression networks within these cells. Here we provide deeper insights into how microRNAs, small endogenously expressed RNAs, regulate the cellular processes involved in the differentiation and function of T follicular helper cells and germinal center B cells, the two main players of the T cell-dependent humoral immune response., (Copyright © 2014 Elsevier Ltd.

- Abstract
Dendritic cells (DCs) that orchestrate mucosal immunity have been studied in mice. Here we characterized human gut DC populations and defined their relationship to previously studied human and mouse DCs. CD103(+)Sirpα(-) DCs were related to human blood CD141(+) DCs and to mouse intestinal CD103(+)CD11b(-) DCs and expressed markers of cross-presenting DCs. CD103(+)Sirpα(+) DCs aligned with human blood CD1c(+) DCs and mouse intestinal CD103(+)CD11b(+) DCs and supported the induction of regulatory T cells. Both CD103(+) DC subsets induced the TH17 subset of helper T cells, while CD103(-)Sirpα(+) DCs induced the TH1 subset of helper T cells. Comparative analysis of transcriptomes revealed conserved transcriptional programs among CD103(+) DC subsets and identified a selective role for the transcriptional repressors Bcl-6 and Blimp-1 in the specification of CD103(+)CD11b(-) DCs and intestinal CD103(+)CD11b(+) DCs, respectively. Our results highlight evolutionarily conserved and divergent programming of intestinal DCs.

- Abstract
CD4(+) T helper (TH) cells regulate appropriate cellular and humoral immune responses to a wide range of pathogens and are central to the success of vaccines. However, their dysregulation can cause allergies and autoimmune diseases. The CD4(+) T cell population is characterized not only by a range of distinct cell subsets, such as TH1, TH2 and TH17 cells, regulatory T cells and T follicular helper cells--each with specific functions and gene expression programmes--but also by plasticity between the different TH cell subsets. In this Review, we discuss recent advances and emerging ideas about how microRNAs--small endogenously expressed oligonucleotides that modulate gene expression--are involved in the regulatory networks that determine TH cell fate decisions and that regulate their effector functions.

- Abstract
Follicular helper T cells (TFH cells) are the prototypic helper T cell subset specialized to enable B cells to form germinal centers (GCs) and produce high-affinity antibodies. We found that expression of microRNAs (miRNAs) by T cells was essential for TFH cell differentiation. More specifically, we show that after immunization of mice with protein, the miRNA cluster miR-17∼92 was critical for robust differentiation and function of TFH cells in a cell-intrinsic manner that occurred regardless of changes in proliferation. In a viral infection model, miR-17∼92 restrained the expression of genes 'inappropriate' to the TFH cell subset, including the direct miR-17∼92 target Rora. Removal of one Rora allele partially 'rescued' the inappropriate gene signature in miR-17∼92-deficient TFH cells. Our results identify the miR-17∼92 cluster as a critical regulator of T cell-dependent antibody responses, TFH cell differentiation and the fidelity of the TFH cell gene-expression program.
