WebNov 4, 2024 · CTLA4 is a potent negative regulator of T-cell response and was identified as a member of the CD28 family ( 40 ). Although CD28 is constitutively expressed on all naive CD4 + and CD8 + T cells and Treg cells, CTLA4 is transiently expressed on the surface of activated T cells ( 41, 42 ).

CD28 and CTLA-4 coreceptor expression and signal transduction
WebMutations in co-inhibitory receptors such as CTLA4 and PD1 are associated with Treg dysfunction, and autoimmune diseases in mice and humans. On the other hand, growing tumors evade immune surveillance by exploiting co-inhibitory signaling through expression of CTLA4, PD1 and PDL-1. WebApr 12, 2024 · Current biomarkers for hypofunctional CD8 + T cells mainly consist of immune inhibitory receptors, interferon-γ (IFN-γ) signaling, or memory transcription factors (1, 6, 9). However, these are not always applied in an integrated manner, thus limiting their scope and creating inconsistencies for interpretations . grace imson md miami
