Deciphering the rules of T cell residency across intestinal compartments

点击翻译按钮获取中文摘要

Tissue-resident memory T cells (TRM) are key for immune protection against infection and cancer at barrier sites including the gut. Whilst much of our understanding of gut TRM comes from studies on the small intestine, how these cells develop and function in the large intestine is unknown. Using state-of-the-art techniques and novel animal models, this project aims to (i) identify molecular pathways by which the local intestinal microenvironment influences TRM development and (ii) how these pathways could modulate TRM generation specifically in the small or large intestine. The expected outcomes are to generate fundamental new knowledge that will have significance for regulation of the immune response.
