Cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) is a protein receptor that works to regulate the immune system. It is found on the surface of T-cells, whose function is to lead the cellular attack on antigens. Usually T-cells are responsible for attacking viruses, cancer cells and other invaders, but when mutated incorrectly they can cause great harm to the body. Stimulating the CTLA-4 receptor turns off the T-cell attack response. The CTLA-4 agonist works by activating the receptor and thus turning off the T-cell attack. Basically, when there is an excess of immune system activity the CTLA-4 protein can be used to tone it down. Mutations and polymorphisms of the gene have been proven to be associated with autoimmune diseases such as multiple sclerosis, lupus, diabetes, celiac disease, Graves’ disease, thyroid-associated orbitopathy, and primary biliary cirrhosis.
