CD8 recognizes and binds to MHC I proteins and helps stabilize the binding of epitopes to T cell receptors. MHC I presents endogenous antigens to CD8+ T cells, which are mainly involved in recognizing and killing virus-infected cells or tumor cells. CD8 binding to MHC I also triggers a series of intracellular signaling events that activate the CD8+ T cells to perform their effector functions.
