CTLA-4 is another checkpoint protein on some T cells that acts as a type of “off switch” to help keep the immune system in check. Ipilimumab (Yervoy) and tremelimumab (Imjuno) are monoclonal antibodies that attach to CTLA-4 and stop it from working. This can help boost the body’s immune response against cancer cells.
