Divergent Phenotypes of Human Regulatory T Cells Expressing the Receptors TIGIT and CD226.
Regulatory T cells (Tregs) play a central role in counteracting inflammation and autoimmunity. A more complete understanding of cellular heterogeneity and the potential for lineage plasticity in human Treg subsets may identify markers of disease pathogenesis and facilitate the development of optimized cellular therapeutics. To better elucidate human Treg subsets, we conducted direct transcripti...
متن کاملThe TIGIT/CD226 axis regulates human T cell function.
T cell Ig and ITIM domain (TIGIT) is a newly identified receptor expressed on T cells that binds to CD155 on the dendritic cell surface, driving them to a more tolerogenic phenotype. Given that TIGIT contains an ITIM motif in its intracellular domain and considering the potential importance of the TIGIT/CD226 pathway in human autoimmune disease, we investigated the specific role of TIGIT in hum...
متن کاملTIGIT predominantly regulates the immune response via regulatory T cells.
Coinhibitory receptors are critical for the maintenance of immune homeostasis. Upregulation of these receptors on effector T cells terminates T cell responses, while their expression on Tregs promotes their suppressor function. Understanding the function of coinhibitory receptors in effector T cells and Tregs is crucial, as therapies that target coinhibitory receptors are currently at the foref...
متن کاملCoexpression of TIGIT and FCRL3 identifies Helios+ human memory regulatory T cells.
Two distinct subsets of CD4(+)Foxp3(+) regulatory T (Treg) cells have been described based on the differential expression of Helios, a transcription factor of the Ikaros family. Efforts to understand the origin and biological roles of these Treg populations in regulating immune responses have, however, been hindered by the lack of reliable surface markers to distinguish and isolate them for sub...
متن کاملTIGIT expressing CD4+T cells represent a tumor-supportive T cell subset in chronic lymphocytic leukemia
While research on T cell exhaustion in context of cancer particularly focuses on CD8+ cytotoxic T cells, the role of inhibitory receptors on CD4+ T-helper cells have remained largely unexplored. TIGIT is a recently identified inhibitory receptor on T cells and natural killer (NK) cells. In this study, we examined TIGIT expression on T cell subsets from CLL patients. While we did not observe any...
