A molecular investigation into the naïve T cell repertoire

点击翻译按钮获取中文摘要

This project aims to interrogate the relationship between T cell receptor (TCR) recognition modes and T cell recruitment and activation. CD8+ T cells are important for adaptive immunity. Their recognition, via TCR, of peptides bound to MHC class I antigen-presenting molecules (pMHCI), initiates a signalling cascade which activates T cells effector functions. All structural information on TCR recognition of pMHCI is based on TCRs prevalent in immune responses, and all recognise pMHCI using a conserved orientation. This project aims to use this observation to study the relationship between TCR recognition modes and T cell recruitment and activation.
