CTLA4 TIM-3 PD-L2 PD1 LAG-3 PD-L1 VISTA and TIGIT are co-inhibitory receptors involved in immune regulation. These proteins regulate T cell responses and tolerance by delivering inhibitory signals that down-modulate effector functions. For example CTLA4 sometimes called CD152 is a 33 kDa protein expressed on regulatory T cells and activated conventional T cells. PD-1 known as PDCD1 is a 55 kDa protein expressed on activated T cells B cells and myeloid cells. These proteins localize mainly at the immune synapse and influence immune signaling pathways.
Biological function summary
These proteins play critical roles in the immune system. They form complexes that send signals to T cells to reduce their activity preventing overactivation that can lead to autoimmune conditions. TIM-3 is particularly involved in inhibiting T cell responses and is expressed on Th1 and cytotoxic T cells. PD-L1 the ligand for PD-1 can be found on antigen-presenting cells and some tumor cells also contributing to immune evasion by tumors.
Pathways
These receptors participate in multiple signaling pathways key to maintaining immune homeostasis. The PD-1/PD-L1 pathway modulates T cell activity during antigen presentation significantly impacting pathways related to immune tolerance. CTLA4 interacts with the CD28 receptor pathway providing a checkpoint in immune activation. These interactions often involve proteins such as B7-1 and B7-2 which are costimulatory molecules that further regulate immune responses.
These proteins have associations with autoimmune diseases and cancer. Dysregulation of CTLA4 for instance links to autoimmune disorders like rheumatoid arthritis. PD1 and PD-L1 have roles in cancer because tumors often exploit these pathways to avoid immune detection. Inhibition of these checkpoint proteins with therapeutic antibodies has shown promise in cancer treatment. Studies also highlight interactions with proteins such as CD28 and PD1 essential factors in understanding their roles in immune evasion and disease progression.
