WebThese ICs play predominant roles in regulating the progression of HIV/SIV infection by mediating T cell responses as well as enriching latent viral reservoirs. It has been demonstrated that enhanced expression of ICs on CD4+ and CD8+ T cells could inhibit cell proliferation and cytokine production. ... PD-1, CTLA-4, and BTLA, members of the ... Web14 Sep 2024 · [0054] BTLA is an inhibitory receptor on T cells that interacts with TNFRSF14. BTLA hi T cells are inhibited in the presence of its ligand. The system of interacting molecules is complex: CD160 (an immunoglobulin superfamily member) and LIGHT (also known as TNFSF14), mediate inhibitory and co-stimulatory activity, respectively.
