The recent advent of methods for high-throughput single-cell molecular profiling has catalyzed a growing sense in the scientific community that the time is ripe to complete the 150-year-old effort to identify all cell types in the human body. The Human Cell Atlas Project is an international collaborative effort that aims to define all human cell types in terms of distinctive molecular profiles (such as gene expression profiles) and to connect this information with classical cellular descriptions (such as location and morphology). An open comprehensive reference map of the molecular state of cells in healthy human tissues would propel the systematic study of physiological states, developmental trajectories, regulatory circuitry and interactions of cells, and also provide a framework for understanding cellular dysregulation in human disease. Here we describe the idea, its potential utility, early proofs-of-concept, and some design considerations for the Human Cell Atlas, including a commitment to open data, code, and community.

Crucial transitions in cancer-including tumor initiation, local expansion, metastasis, and therapeutic resistance-involve complex interactions between cells within the dynamic tumor ecosystem. Transformative single-cell genomics technologies and spatial multiplex in situ methods now provide an opportunity to interrogate this complexity at unprecedented resolution. The Human Tumor Atlas Network (HTAN), part of the National Cancer Institute (NCI) Cancer Moonshot Initiative, will establish a clinical, experimental, computational, and organizational framework to generate informative and accessible three-dimensional atlases of cancer transitions for a diverse set of tumor types. This effort complements both ongoing efforts to map healthy organs and previous large-scale cancer genomics approaches focused on bulk sequencing at a single point in time. Generating single-cell, multiparametric, longitudinal atlases and integrating them with clinical outcomes should help identify novel predictive biomarkers and features as well as therapeutically relevant cell types, cell states, and cellular interactions across transitions. The resulting tumor atlases should have a profound impact on our understanding of cancer biology and have the potential to improve cancer detection, prevention, and therapeutic discovery for better precision-medicine treatments of cancer patients and those at risk for cancer.

- Abstract
Effective immunosurveillance of cancer requires the presentation of peptide antigens on major histocompatibility complex Class I (MHC-I). Recent developments in proteomics have improved the identification of peptides that are naturally presented by MHC-I, collectively known as the “immunopeptidome”. Current approaches to profile tumor immunopeptidomes have been limited to in vitro investigation, which fails to capture the in vivo repertoire of MHC-I peptides, or bulk tumor lysates, which are obscured by the lack of tumor-specific MHC-I isolation. To overcome these limitations, we report here the engineering of a Cre recombinase-inducible affinity tag into the endogenous mouse MHC-I gene and targeting of this allele to the KrasLSL-G12D/+; p53fl/fl (KP) mouse model (KP; KbStrep). This novel approach has allowed us to isolate tumor-specific MHC-I peptides from autochthonous pancreatic ductal adenocarcinoma (PDAC) and lung adenocarcinoma (LUAD) in vivo. With this powerful analytical tool, we were able to profile the evolution of the LUAD immunopeptidome through tumor progression and show that in vivo MHC-I presentation is shaped by post-translational mechanisms. We also uncovered novel, putative LUAD tumor associated antigens (TAAs). Many peptides that were recurrently presented in vivo exhibited very low expression of the cognate mRNA, provoking reconsideration of antigen prediction pipelines that triage peptides according to transcript abundance. Beyond cancer, the KbStrep allele is compatible with a broad range of Cre-driver lines to explore antigen presentation in vivo in the pursuit of understanding basic immunology, infectious disease, and autoimmunity.

Immunology ,Immunology and Allergy - Abstract
Following acute infection, pathogen-specific CD8+ T cells proliferate and divide in a heterogeneous manner, giving rise to effector and memory T cells with distinct migratory patterns. This migratory division of labor ensures that the host is efficiently scanned for ongoing or recurring infections. Recent evidence suggests that the presumed migratory behavior of the classical effector memory T cell subset needs revision. Here, we report that terminally differentiated effector and effector memory T cells adhere to and patrol the endothelium, while less differentiated T cells migrate into peripheral tissues. Interestingly, patrolling T cells have been observed at vascular beds such as the dermal microvasculature, where they concentrate in arterioles and preferentially migrate against the blood flow. Patrolling T cells survey the endothelium in the search for cognate antigen and, once encountered, cease their migration and establish long-lived interactions with peptide-presenting endothelial cells without inducing cytotoxicity. Finally, single-cell RNA-Seq analysis of patrolling CD8+ T effector cells and blockade experiments to prevent patrolling have unveiled a key and unexpected role for patrolling in the generation and maintenance of the intravascular CD8+ CX3CR1high KLRG-1+ effector memory T cell subset, which in turn is relevant for long-term protective immunity.

CD8 T cells targeting peptides presented by human leukocyte antigen (HLA) class II are atypical. Little is known about how the CD8 T cell receptor (TCR) recognizes peptides on HLA class II. We analyzed the TCR repertoire of a class II-restricted CD8 T cells targeting a HIV peptide. We identified an atypical HIV-specific CD8 response to DV16 peptide on HLA-DRB1*11. We sequenced the TCR of the class II-tetramer sorted cells. To measure the binding kinetics of the TCR with the peptide-MHC we used surface plasmon resonance (SPR). Analysis of 68 sequences showed that TCR-beta repertoire has a single TRBV2*01 clonotype. We looked at 64 sequences of TCRalpha and found that the repertoire had two clonotypes: TRAV26-1*02 and TRAV6*02. SPR revealed that only the TRAV6 was able to bind to the peptide-MHC. We studied 27 sequences of the CD4 T cells targeting the same MHC class II-peptide. We observed a polyclonal response of 16 clonotypes. 13 clonotypes used the same TRBV2*01 gene but had different rearrangements. Interestingly, two of these sequences are exactly the same as the dominant clonotype from the CD8 response. We found that the TCR is shared between CD8 and CD4 T cells targeting the same class II HLA-peptide. These data suggest that atypical CD8 cells express two different TCR alpha, possibly due to inefficient allelic exclusion during development. The use of the same TRBV2*01 by different CD4 clonotypes may suggest an atypical docking of TCR in the binding with peptide-HLA.
