WebApr 12, 2024 · Immune checkpoint receptors have a critical role in safeguarding the appropriate function of regulatory (Tregs) and effector T cells and maintaining overall immune homeostasis. Antibodies against immune checkpoint receptors CTLA-4, PD-1, and PD-L1 have entirely transformed the treatment landscape of multiple solid and … Four stimulatory checkpoint molecules are members of the tumor necrosis factor (TNF) receptor superfamily—CD27, CD40, OX40, GITR and CD137. Another two stimulatory checkpoint molecules belong to the B7-CD28 superfamily—CD28 itself and ICOS. • CD27: This molecule supports antigen-specific expansion of naïve T cells and is vital for the generation of T cell memory. CD27 is also a memory marker of B cells. CD27's activity is gover…
