regulates immune response by inhibiting T cell activation
Cytotoxic T-Lymphocyte Antigen 4 (CTLA-4) is a protein found on the surface of T cells, which are a type of immune cell. It acts as an "off switch" to help regulate the immune system by preventing it from attacking the body's own tissues. This protein is crucial in maintaining immune tolerance and preventing autoimmune diseases.
