- Abstract
Lung cancer remains the deadliest cancer in the world, and lung cancer survival is heavily dependent on tumor stage at the time of detection. Low-dose computed tomography screening can reduce mortality; however, annual screening is limited by low adherence in the United States of America and still not broadly implemented in Europe. As a result, less than 10% of lung cancers are detected through existing programs. Thus, there is a great need for additional screening tests, such as a blood test, that could be deployed in the primary care setting.

Schöbel, Christoph, Große Sundrup, Martina, Straßburg, Svenja, Woehrle, Holger, Vogelmeier, Claus, and Taube, Christian
- Abstract
Die Digitalisierung wird die Medizin im Ganzen und die Pneumologie im Speziellen verändern. Digitalisierung sollte jedoch kein Selbstzweck sein. Ebenso wenig sollte und kann Digitalisierung die menschliche Komponente in der Medizin ersetzen. Patienten informieren sich jedoch zunehmend über Gesundheitsthemen im Internet, messen ihre Vitalwerte in der Häuslichkeit oder kommen bereits mit einer Diagnose „made by Dr. Google“. Ärzten kommt daher zunehmend eine Beraterfunktion zu, die einer der wichtigsten Aspekte einer menschlichen und empathischen Medizin ist. In diesem Sinne sollten Ärzte daher auch die digitale Transformation der Medizin proaktiv mitgestalten. Vor dem Hintergrund des Mottos des diesjährigen Kongresses werden wir in unserem Beitrag in die kürzere Vergangenheit blicken, aktuelle Entwicklungen aufnehmen und auch einen Blick in die Zukunft einer digitalen und empathischen Pneumologie wagen.

- Abstract
Hintergrund: Schweres Asthma stellt in Deutschland für betroffene Patient:innen und versorgende Einrichtungen ebenso wie für das Gesundheitssystem ein bleibendes Problem dar. Daher wurde das German Asthma Net (GAN) mit dem Ziel gegründet, die aktuelle Versorgungsrealität besser zu erfassen, das Krankheitsbild besser zu verstehen und die Behandlung zu optimieren. Fragestellung: Es erfolgt die Darstellung der Entwicklung des Registers Schweres Asthma des German Asthma Net e. V. seit Vereinsgründung. Material und Methode: Die Historie des Vereins mit Einblick in die Vereinsstruktur, Aufgabenverteilung sowie Aufbau und Entwicklung des Registers Schweres Asthma werden dargestellt. Ergebnisse: Seit Beginn der Vereinsgründung und der Etablierung des Registers Schweres Asthma ist ein kontinuierlicher Anstieg der Patientenzahl zu beobachten und damit verbunden eine gute Vernetzung wichtiger Wirkungskreise. Unter Mitarbeit von Registerzentren in Deutschland und Europa, Kooperationspartnern aufseiten von Fachgesellschaften und Sponsoring konnte das Register für schweres Asthma mit aktuell über 3700 Patient:innen aufgebaut werden. Patient:innen können sich über die Webseite eine geeignete Anlaufstelle für schweres Asthma suchen. Schlussfolgerung: Durch die enge Kooperation mit allen Beteiligten konnte das weltweit größte spezifische Register für schweres Asthma etabliert werden, mit dessen Hilfe wichtige Fragen zur Pathologie, Epidemiologie und Therapie der entsprechenden Patient:innen gestellt und beantwortet werden können. Das GAN stellt damit einen wichtigen Beitrag zur Optimierung der Versorgung dieser besonders betroffenen Patientengruppe dar.

- Abstract
Antibiotics, among the most used medications in children, affect gut microbiome communities and metabolic functions. These changes in microbiota structure can impact host immunity. We hypothesized that early-life microbiome alterations would lead to increased susceptibility to allergy and asthma. To test this, mouse pups between postnatal days 5–9 were orally exposed to water (control) or to therapeutic doses of azithromycin or amoxicillin. Later in life, these mice were sensitized and challenged with a model allergen, house dust mite (HDM), or saline. Mice with early-life azithromycin exposure that were challenged with HDM had increased IgE and IL-13 production by CD4+T cells compared to unexposed mice; early-life amoxicillin exposure led to fewer abnormalities. To test that the microbiota contained the immunological cues to alter IgE and cytokine production after HDM challenge, germ-free mice were gavaged with fecal samples of the antibiotic-perturbed microbiota. Gavage of adult germ-free mice did not result in altered HDM responses, however, their offspring, which acquired the antibiotic-perturbed microbiota at birth showed elevated IgE levels and CD4+cytokines in response to HDM, and altered airway reactivity. These studies indicate that early-life microbiota composition can heighten allergen-driven Th2/Th17 immune pathways and airway responses in an age-dependent manner.

9. Impact of Changes in Human Airway Epithelial Cellular Composition and Differentiation on SARS-CoV-2 Infection Biology

- Abstract
The consequences of infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can range from asymptomatic to fatal disease. Variations in epithelial susceptibility to SARS-CoV-2 infection depend on the anatomical location from the proximal to distal respiratory tract. However, the cellular biology underlying these variations is not completely understood. Thus, air-liquid interface cultures of well-differentiated primary human tracheal and bronchial epithelial cells were employed to study the impact of epithelial cellular composition and differentiation on SARS-CoV-2 infection by transcriptional (RNA sequencing) and immunofluorescent analyses. Changes of cellular composition were investigated by varying time of differentiation or by using specific compounds. We found that SARS-CoV-2 primarily infected not only ciliated cells but also goblet cells and transient secretory cells. Viral replication was impacted by differences in cellular composition, which depended on culturing time and anatomical origin. A higher percentage of ciliated cells correlated with a higher viral load. However, DAPT treatment, which increased the number of ciliated cells and reduced goblet cells, decreased viral load, indicating the contribution of goblet cells to infection. Cell entry factors, especially cathepsin L and transmembrane protease serine 2, were also affected by differentiation time. In conclusion, our study demonstrates that viral replication is affected by changes in cellular composition, especially in cells related to the mucociliary system. This could explain in part the variable susceptibility to SARS-CoV-2 infection between individuals and between anatomical locations in the respiratory tract.

- Abstract
Background: Patients with obstructive sleep apnea (OSA) most commonly receive positive airway pressure therapy (PAP) as primary treatment, which is highly effective when used consistently. Little is known about the preferences for and relevance of attributes of OSA treatments, especially of non-PAP alternatives. The aim of this study was to evaluate treatment preferences and willingness to pay (WTP) among patients with and without previous experience of OSA therapies. Methods: A discrete choice experiment and a structured survey were applied to patients presenting for overnight polysomnography at a tertiary sleep center. Medical variables were obtained from hospital case records. Results: Over a period of 4 months, 241 subjects were enrolled and answered the questionnaire (61.8% with an existing diagnosis, 38.2% with a new diagnosis). The most preferred treatment among all patients was PAP therapy (51.1%), followed by mandibular advancement devices (18.1%), hypoglossal nerve stimulation (17.2%), and medication (13.7%). Approval for the different treatments varied by gender as well as by OSA therapy experience. The importance of attributes of OSA treatment varied too, with low rates of treatment-related side effects being equally important, independent of the preferred therapy. The most often stated monthly WTP for optimal sleep was € 50, with increasing age leading to lower WTP values. Conclusion: Preferences for OSA therapies vary among patients and patient subgroups. PAP therapy is the most preferred treatment, though non-PAP interventions receive high approval ratings too, particularly in treatment-naïve patients. The importance of treatment attributes varies as well, depending on the choice of preferred treatment.

- Abstract
Inhalation devices are the main method of delivering treatments to patients with chronic obstructive pulmonary disease (COPD). However, there are many devices available, which can lead to confusion and poor inhaler technique. To help doctors decide which device to give to their patients, they consider whether the patient would be happy with the device and whether they can use it correctly. This study pooled data from two large real-life studies to assess patient satisfaction with the Respimat®Soft Mist™ inhaler. Patients assessed their satisfaction and willingness to continue using the device at the end of the study period.

- Abstract
Mast cells (MCs) are capable of executing powerful inflammatory response programs triggered by surface IgE cross-linking or through pattern recognition receptors. The question of how MCs contribute to human disease has been intensely investigated and stimulated much controversy. Correlative evidence comes from human studies, pointing to pathogenetic or protective MC functions in patients with atopic conditions, autoimmune disorders, type 2 diabetes, chronic urticaria, mastocytosis, and cancer. Experiments in MC-deficient mice underpinned key roles for MCs in patients with IgE-mediated allergic conditions. Important pathogenetic MC contributions to other inflammatory and neoplastic conditions were suggested by studies in traditional KIT mutant MC-deficient mouse strains. However, many of these findings were not reproduced in more recently developed improved mouse models of MC deficiency, largely ruling out roles for MCs in mouse models for autoimmune disease, diabetes, and cancer. We discuss limitations of studies in mice and human subjects and provide suggestions for how they can be overcome, such as through the development of specific and selective MC-targeted treatments.

- Abstract
Endobronchial ultrasound–guided transbronchial needle aspirations (EBUS-TBNAs) are well established for staging lung cancer. A growing number of publications report on lymphoma diagnosis via EBUS-TBNA–acquired cytology; however current guidelines recommend histologic diagnosis. Research on the value of EBUS-TBNA–acquired cytology versus surgical-acquired histology in the diagnosis of lymphoma is lacking. We conducted a retrospective review of patients with mediastinal lymphoma diagnosed between 2010 and 2016. Mediastinal lymphadenopathy was accessible through both EBUS-TBNAs and surgical procedures. All data were extracted from our clinic's medical database and analyzed. Fifty-one patients newly diagnosed with lymphoma in the mediastinum were identified (median age, 43.5 years; mean age, 48.6 ± 20.6 years). A minimally invasive procedure was performed as a first diagnostic step in 29 patients, whereas surgical biopsy was performed in the remaining 22. The time to final diagnosis was significantly longer if a minimally invasive procedure was performed first compared with a surgical procedure (mean, 44 days [median, 38 days] vs 16 days [median, 8 days]; p < 0.030). The number of procedures to obtain a final diagnosis ranged from one to five (median, 2 procedures per patient) in the EBUS-TBNA group. This was significantly higher than that in the surgical group (median, 1 procedure per patient; p < 0.00005). We demonstrate that surgical biopsies are safe and well tolerated for lymphoproliferative disease diagnosis and lead to a final diagnosis in the shortest possible time. Unnecessary procedures were significantly reduced if a surgical biopsy was performed as the first step. [ABSTRACT FROM AUTHOR]

- Abstract
Thymic epithelial and neuroendocrine carcinomas are rare malignancies, and only a few prognosticators are defined. Surgery is the mainstay of treatment, and complete resection contributes to superior outcome. Systematic lymph node dissection is not routinely performed in thymic malignancies. The aim of this study was to assess the impact of histologically confirmed lymph node metastases on the outcome after thymectomy. We identified 53 patients with thymic epithelial or neuroendocrine carcinomas who underwent surgical resection at our center between 1999 and 2016. The clinical follow-up was retrospectively collected, and the impact of clinicopathologic factors on overall survival was analyzed. Ninety-one percent of the patients were treated taking a multimodal approach. Median overall survival was 11.3 years. Lymph node metastases were identified in 16 patients (30.2%; 11 pN1 and 5 pN2). Lymph node metastasis was associated with inferior overall survival (hazard ratio [HR] 3.03, 95% confidence interval [CI]: 1.03 to 8.87, p = 0.044). Masaoka-Koga stage (4 versus 1 to 3) was another significant prognosticator (HR 7.01, 95% CI: 2.52 to 19.50, p = 0.0002). Organ metastases were present in 18 patients at the time of thymectomy and were associated with inferior outcome (HR 5.8, 95% CI: 2.04 to 16.79, p = 0.001). This retrospective, single-center analysis demonstrates a high rate of lymph node metastasis in resectable thymic neuroendocrine tumors or carcinomas. Positive lymph nodes are associated with an inferior outcome. Prospective studies are warranted to explore whether this outcome can be improved by systematic lymphadenectomy and adjuvant therapies. Nevertheless, lymphadenectomy provides optimal staging and should be a routine part of surgery for patients with thymic malignancies. [ABSTRACT FROM AUTHOR]

- Abstract
Eosinophils are predominantly known for their contribution to allergy. Here, we have examined the function and regulation of gastrointestinal eosinophils in the steady-state and during infection with Helicobacter pylori or Citrobacter rodentium. We find that eosinophils are recruited to sites of infection, directly encounter live bacteria, and activate a signature transcriptional program; this applies also to human gastrointestinal eosinophils in humanized mice. The genetic or anti–IL-5–mediated depletion of eosinophils results in improved control of the infection, increased inflammation, and more pronounced Th1 responses. Eosinophils control Th1 responses via the IFN-γ–dependent up-regulation of PD-L1. Furthermore, we find that the conditional loss of IFN-γR in eosinophils phenocopies the effects of eosinophil depletion. Eosinophils further possess bactericidal properties that require their degranulation and the deployment of extracellular traps. Our results highlight two novel functions of this elusive cell type and link it to gastrointestinal homeostasis and anti-bacterial defense.

- Abstract
Objective: To enlarge the donor pool for lung transplantation, an increasing number of extended criteria donor lungs are used. However, in more than 50% of multi-organ donors the lungs are not used. Ex vivo lung perfusion offers a unique possibility to evaluate and eventually recondition the injured donor lungs. The aim of our study was to assess the enlargement of the donor pool and the outcome with extended criteria donor lungs after ex vivo lung perfusion.Patients and Methods: Data were prospectively collected in our lung transplant database. We compared the results of lung transplants after ex vivo lung perfusion with those after conventional cold static preservation. In total, 11 extended criteria donor lungs processed with ex vivo lung perfusion and 41 cold static preservation lungs transplanted consecutively between May 2016 and May 2017 were evaluated. Normothermic ex vivo lung perfusion was performed according to the Toronto protocol for 4 h. Cold static preservation lungs were stored in low-potassium dextran solution.Results: Ex vivo lung perfusion lungs before procurement had significantly lower PaO2/FiO2(P/F) ratios and more X-ray abnormalities. There were no statistically significant differences for pre-donation ventilation time, smoking history, or sex. After reconditioning with ex vivo lung perfusion, 9 out of 11 processed lungs were considered suitable and successfully transplanted. The mean postoperative ventilation time and in-hospital stay were not significantly different in ex vivo lung perfusion and cold static preservation recipients.Conclusion: Ex vivo lung perfusion can safely be used in the evaluation of lungs initially considered not suitable for transplantation. The primary outcome was not negatively affected and normothermic ex vivo lung perfusion is a useful tool to increase the usage of potentially transplantable lungs.

- Abstract
The worldwide incidence and prevalence of asthma continues to increase. Asthma is now understood as an umbrella term for different phenotypes or endotypes, which arise through different pathophysiologic pathways. Understanding the many factors contributing to development of the disease is important for the identification of novel therapeutic targets for the treatment of certain asthma phenotypes. The hygiene hypothesis has been formulated to explain the increasing prevalence of allergic disease, including asthma. This hypothesis postulates that decreased exposure at a young age to certain infectious agents as a result of improved hygiene, increased antibiotic use and vaccination, and changes in lifestyle and dietary habits is associated with changes in the immune system, which predispose subjects to allergy. Many microbes, during their coevolution with human subjects, developed mechanisms to manipulate the human immune system and to increase their chances of survival. Improving models of asthma, as well as choosing adequate end points in clinical trials, will lead to a more complete understanding of the underlying mechanisms, thus providing an opportunity to devise primary and secondary interventions at the same time as identifying new molecular targets for treatment. This article reports the discussion and conclusion of a workshop under the auspices of the Netherlands Lung Foundation to extend our understanding of how modulation of the immune system by bacterial, parasitic, and viral infections might affect the development of asthma and to map out future lines of investigation.

- Abstract
Bronchial asthma and chronic obstructive pulmonary disease (COPD) are chronic diseases that are associated with inflammation and structural changes in the airways and lungs. Recent findings have implicated Wnt pathways in critically regulating inflammatory responses, especially in asthma. Furthermore, canonical and noncanonical Wnt pathways are involved in structural changes such as airway remodeling, goblet cell metaplasia, and airway smooth muscle (ASM) proliferation. In COPD, Wnt pathways are not only associated with structural changes in the airways but also involved in the development of emphysema. The present review summarizes the role and function of the canonical and noncanonical Wnt pathway with regard to airway inflammation and structural changes in asthma and COPD. Further identification of the role and function of different Wnt molecules and pathways could help to develop novel therapeutic options for these diseases.

- Abstract
Respiratory infections are a major clinical problem, and treatment is increasingly complicated by the emergence of microbial antibiotic resistance. Development of new antibiotics is notoriously costly and slow; therefore, alternative strategies are needed. Antimicrobial peptides, central effector molecules of the immune system, are being considered as alternatives to conventional antibiotics. These peptides display a range of activities, including not only direct antimicrobial activity, but also immunomodulation and wound repair. In the lung, airway epithelial cells and neutrophils in particular contribute to their synthesis. The relevance of antimicrobial peptides for host defense against infection has been demonstrated in animal models and is supported by observations in patient studies, showing altered expression and/or unfavorable circumstances for their action in a variety of lung diseases. Importantly, antimicrobial peptides are active against microorganisms that are resistant against conventional antibiotics, including multidrug-resistant bacteria. Several strategies have been proposed to use these peptides in the treatment of infections, including direct administration of antimicrobial peptides, enhancement of their local production, and creation of more favorable circumstances for their action. In this review, recent developments in antimicrobial peptides research in the lung and clinical applications for novel therapies of lung diseases are discussed.

- Abstract
The management of care of chronic obstructive pulmonary disease improved over the last years but is still very complex. Both over- and underdiagnosis are often reported and misclassification of disease severity is common. Differentiating between chronic obstructive pulmonary disease, asthma and asthma-chronic obstructive pulmonary disease overlap syndrome remains difficult. Much is known about the effectiveness of treatment approaches in chronic obstructive pulmonary disease, but patients are often not treated according to the guidelines, and we need more evidence on effectiveness in phenotypes of chronic obstructive pulmonary disease. Care coordination is of great importance and can help to further improve care for chronic obstructive pulmonary disease patients. Pulmonary rehabilitation and self-management are considered important aspects of chronic obstructive pulmonary disease care. In our opinion, there is a major role for eHealth to improve coordination of care of chronic obstructive pulmonary disease.

Auch bei der Behandlung des Asthma bronchiale sind in den letzten Jahren erhebliche Fortschritte in unserem Verständnis der Erkrankung erzielt worden. Dieses scheint nun auch in spezifische Therapieansätze zu resultieren, die nicht für alle Patienten sondern nur für eine spezifische Gruppe eingesetzt werden. Dazu gehören neben dem bereits zugelassenen anti-IgE auch neue Antikörper so wie anti-IL-5 und anti-IL-13. Für welche Patientengruppen diese am besten eingesetzt werden können ist zur Zeit Stand der Forschung. Zitierweise:Taube C. Bronchial Asthma: is personalized therapy on the horizon?

- Abstract
Background: The prevalence of obesity and asthma has increased concurrently over the last decades, suggesting a link between obesity and asthma. However, asthma might not be adequately diagnosed in this population. Aim: To investigate whether not only overdiagnosis but also underdiagnosis of asthma is present in an obese population. Methods: Morbidly obese subjects with or without physician-diagnosed asthma were recruited from a pre-operative screening programme for bariatric surgery, and were characterized using an extensive diagnostic algorithm. Results: 473 subjects were screened; 220 met inclusion criteria, and 86 agreed to participate. Among the 32 participating subjects who had a physician diagnosis of asthma, reversible airway obstruction and/or bronchial hyperresponsiveness could only be detected in 19 patients (59%, 95% CI [0.41-0.76]), whereas in 13 patients (41%, 95% CI [0.24-0.50]) the diagnosis of asthma could not be confirmed (overdiagnosis). In contrast, in the remaining 54 patients, 17 (31%, 95% CI [0.20-0.46]) were newly diagnosed with asthma (underdiagnosis). Conclusion: Besides overdiagnosis, there is also substantial underdiagnosis of asthma in the morbidly obese. Symptoms could be incorrectly ascribed to either obesity or asthma, and therefore also in the morbidly obese the diagnosis of asthma should also be based on pulmonary function testing.

- Abstract
Introduction: Delays in the start of the first operation of the day often lead to conflicts among the involved physicians and nurses. Data on such delays have already been published for individual hospitals, but robust comparative data from a large number of institutions have not been available till now. Methods: The study is based on the operating room (OR) documentation of four surgical services (general surgery, trauma/orthopedic surgery, gynecology, and ear nose throat [ENT] surgery) in 22 German hospitals over a nine-month period. Three process points ("patient arrival in OR suite," "anesthesia ready," and "incision") were analyzed for the first operation of the day in each OR. Results: 21 357 operations in the first position were analyzed. The percentage of delays differed markedly for the three process points. The incision was delayed in more than 70% of the general surgical and trauma/orthopedic cases, but less often in gynecological (61 ± 24%) and ENT cases (42 ± 29%). The frequency of delays longer than 10 minutes was between 20% and 40%. The mean delay in delayed cases ranged from 14.1 ± 5.4 to 21.6 ± 8.2 minutes depending on the type of service and process point. Conclusion: The processes for the first operation of the day are not optimally structured in the hospitals whose cases were analyzed in this study. Delayed starts were common. [ABSTRACT FROM AUTHOR]

Background: IL-10–treated dendritic cells (DCs) have been shown to inhibit T-cell responses through induction of anergy and regulatory T cells in various model systems, including allergic inflammation, but the factors being involved in this inhibition are still unclear. Objective: This study set out to analyze such factors produced or induced by IL-10–treated DCs by using gene expression profiling and to explore their function. Methods: CD4
+ T cells from allergic donors were stimulated with autologous monocyte-derived allergen-pulsed mature DCs or IL-10–treated DCs. After 24 hours, the transcriptional profile was analyzed by using Affymetrix technology. Results were validated by using quantitative real-time PCR, protein expression, and functional in vitro and in vivo studies. Results: In CD4+ T-cell/IL-10–treated DC cocultures the expression of several known genes, such as IL13, IL5 and OX40, was suppressed. Interestingly, there was only one factor that was strongly upregulated: the DC-derived chemokine CCL18. In vitro addition of CCL18 to cocultures of CD4+ T cells and allergen-pulsed DCs resulted in a similar inhibition of TH 2 cytokine production as induced by allergen-pulsed IL-10–treated DCs without exogenous CCL18, whereas TH 1 cytokine production, IL-10 production, and proliferation were not affected. Furthermore, in a humanized mouse model of allergy using PBMC-engrafted NOD-scid-γc−/− mice, CCL18, but not another TH 2-associated chemokine, CCL17, inhibited airway reactivity and lung inflammation. Chemotaxis assays revealed that CCL18 preferentially attracted regulatory T cells and, less efficiently, TH 2 cells. Conclusion: These data demonstrate that CCL18 might represent a molecule of significant importance in immunoregulation and might be a therapeutic target in patients with allergic airway diseases.

- Abstract
Summary: Background: Benefit of treatment with the monoclonal anti-IgE-antibody omalizumab in severe IgE-dependent asthma requires a significant reduction of serum free IgE concentrations. It is unclear if monitoring free serum IgE is clinically meaningful once omalizumab treatment is initiated. Methods: Free IgE and omalizumab serum concentrations were quantified in 22 patients with severe asthma (68% female, 47 ± 11 yrs, mean (±SD) pre-bronchodilator FEV
1 62 ± 13%, baseline mean (±SEM) free serum IgE 652 ± 136 ng/ml) treated with omalizumab for 4 months using a Recovery-ELISA. Results: Omalizumab treatment reduced free serum IgE prior to the second omalizumab injection by 73%, after 16 weeks by 81% to 58 ± 12 ng/ml (p < 0.001 vs. baseline). 17 patients responded to anti-IgE therapy as judged by physician-rated global evaluation of treatment effectiveness. There was neither a relation between free serum IgE concentrations and treatment response nor a significant or clinically relevant correlation between free IgE levels and changes in lung function, exhaled NO, asthma control, and quality of life. Serum concentrations of omalizumab were detected in all patients and reached a stable phase within 8 weeks. Conclusions: Monitoring free IgE and omalizumab serum concentrations in patients treated with omalizumab does not predict clinical response nor does it add to the decision to continue or stop treatment. However, routine measurements of free IgE may be clinically relevant to demonstrate an adequate reduction in free IgE in patients not responding to omalizumab therapy.

- Abstract
Summary: Forced inspiratory measures have been described to reflect the reduction in dyspnoea upon bronchodilation in severe COPD. Based on this we evaluated the applicability and usefulness of a portable device for the assessment of forced inspiration. In 37 patients with COPD (GOLD II/II/IV n = 16/15/6, mean ± SD FEV
1 46.2 ± 15.4%pred) lung function was recorded prior to inhalation of 24 μg formoterol and 30 min later. Assessments comprised spirometry including forced inspiration, body plethysmography, maximum inspiratory flow (InCheck, Clement Clarke), and changes in dyspnoea via visual analogue scale (VAS). The sequence was repeated on a second day to assess reproducibility. Bronchodilation by formoterol was detectable in all functional indices (p < 0.05 each) except total lung capacity. FEV1 improved by (mean ± SD) 11.1 ± 10.3%, forced inspiratory volume in 1s (FIV1 ) by 11.6 ± 13.5%, inspiratory peak flow (PIF) by 10.7 ± 16.2%, and inspiratory flow determined by the InCheck device (IF-IC) by 11.9 ± 14.4%. Remarkably, the changes of IF-IC (p < 0.001) but not those of other measures except FIV1 (p < 0.05) were related to those of dyspnoea. Effects on IF-IC showed reproducibility comparable to that of other indices. The results suggest that a simple, portable device for recording forced inspiration could be useful in monitoring COPD, as a functional correlate of acute changes in dyspnoea.

- Abstract
Mast cells have been regarded for a long time as effector cells in IgE mediated type I reactions and in host defence against parasites. However, they are resident in all environmental exposed tissues and express a wide variety of receptors, suggesting that these cells can also function as sentinels in innate immune responses. Indeed, studies have demonstrated an important role of mast cells during the induction of life-saving antibacterial responses. Furthermore, recent findings have shown that mast cells promote and modulate the development of adaptive immune responses, making them an important hinge of innate and acquired immunity. In addition, mast cells and several mast cell-produced mediators have been shown to be important during the development of allergic airway diseases. In the present review, we will summarize findings on the role of mast cells during the development of adaptive immune responses and highlight their function, especially during the development of allergic asthma.

- Abstract
Naturally occurring CD4+CD25+ regulatory T cells (Tregs) represent a unique T-cell lineage that is endowed with the ability to actively suppress immune responses. Therefore, approaches to modulate Treg function in vivo could provide ways to enhance or reduce immune responses and lead to novel therapies. Here we show that the CD4 binding human immunodeficiency virus-1 envelope glycoprotein gp120 is a useful and potent tool for functional activation of human Tregs in vitro and in vivo. Gp120 activates human Tregs by binding and signaling through CD4. Upon stimulation with gp120, human Tregs accumulate cyclic adenosine monophosphate (cAMP) in their cytosol. Inhibition of endogeneous cAMP synthesis prevents gp120-mediated Treg activation. Employing a xenogeneic graft versus host disease model that has been shown to be applicable for the functional analysis of human Tregs in vivo, we further show that a single dose of gp120 is sufficient to prevent lethal graft versus host disease and that the tolerizing effect of gp120 is strictly dependent on the presence of human Tregs and their up-regulation of cAMP upon gp120-mediated activation. Our findings demonstrate that stimulation via the CD4 receptor represents a T-cell receptor–independent Treg activating pathway with potential to induce immunologic tolerance in vivo.

- Abstract
Until recently, IgE-activated mast cells have been regarded merely as effector cells of adaptive immune responses, involved in allergic reactions and mucosal immunity to parasites. Herein, we report that murine dermal mast cells, activated by local administration of a cream containing the synthetic TLR7 ligand imiquimod, are essential to initiate an early inflammatory reaction. The mast-cell–derived cytokines TNF-α and IL-1β play an important role in this process. Furthermore, TLR7-activated mast cells are also able to promote the emigration of Langerhans cells, which partly depends on the expression of mast-cell–derived IL-1β. We have previously shown that TLR7 ligation enhances transcutaneous immunization evoked by topical application of vaccine antigens to the skin, a procedure that directly targets skin-resident antigen-presenting cells. Consequently, we now demonstrate here that the capacity to mount a peptide-specific cytotoxic T-lymphocyte response following transcutaneous immunization using imiquimod as adjuvant is severely impaired in mast-cell–deficient mice. Thus, these findings demonstrate the potent versability of alternatively activated mast cells at the interface of innate and adaptive immunity.
