Mouse CD152/CTLA-4
The lymphocyte surface antigen CD152, also known as CTLA-4, is related to the co-stimulatory molecule CD28, and both molecules share common B7 family counter-receptors.1-4 However CD152 is thought to be a negative regulator of T cell activation1-3 and may play a role in apoptotic control of T cells. CD152 exists as a 69 kDa homodimer1, and is relatively conserved among humans, mice and chickens.2
