Phenotypic models of t cell activation

WebAug 12, 2024 · T cells are key to anti-tumor immune responses and their ability to strongly engage antigen on tumors is crucial to their efficacy. Here, Purcarea and Jarosch et al. studied how T cell receptor (TCR) avidity of tumor-specific T cells affected their anti-tumor capabilities using mouse modeling and two melanoma patients.In mice, they found that … WebThese T cell functions critically rely on productive binding between T cell antigen receptors (TCRs) and antigens, typically short peptides bound to major-histocompatibility-complexes (pMHCs), displayed on the surface of a variety of cells referred to as antigen-presenting-cells (APCs). Upon activation, T cells may proliferate, differentiate ...
