Clinical outcomes in colorectal cancer (CRC) correlate with T cell infiltrates, but the specific contributions of heterogenous types remain unclear. To investigate diverse function cells CRC, we profiled 37,931 from tumors and adjacent normal colon 16 patients CRC respect to transcriptome, TCR sequence, surface markers. Our analysis identified phenotypically functionally distinguishable effector types. We employed single-cell gene signatures these subsets query TCGA database assess their...
Celiac disease (CD) is an autoimmune in which intestinal inflammation induced by dietary gluten. The means through gluten-specific CD4
Abstract Somatic evolution leads to the emergence of clonal diversity across tissues with broad implications for human health. A striking example somatic is VEXAS (Vacuoles E1 enzyme X-linked Autoinflammatory Somatic) syndrome, caused by UBA1 mutations in hematopoietic stem cells (HSCs), inducing treatment-refractory, systemic inflammation. However, mechanisms that lead survival and expansion mutant HSCs are unknown, limiting development effective therapies. The lack animal or cellular...
Somatic mosaicism is a hallmark of malignancy that also pervasively observed in human physiological aging, with clonal expansions cells harboring mutations recurrently mutated driver genes. Bulk sequencing tissue microdissection captures mutation frequencies, but cannot distinguish which co-occur the same clones to reconstruct architectures, nor phenotypically profile populations delineate how impact cellular behavior. To address these challenges, we developed single-cell...
Despite the widespread use and success of immune checkpoint blockade (ICB) therapies targeting negative costimulatory proteins CTLA4 PD1, means through which they affect T cells remain poorly understood. Notably, cell populations that these act upon unknown. Through single-cell TCR-seq, RNA-seq CITE-seq coupled with surgical biopsy, we longitudinally tracked fate clones within tumors in response to ICB immunogenic mouse models cancer. In this context, found both acted distinct complementary...
