CD4

CD4, recognized as a surface antigen, is a glycoprotein found on the membranes of a specific subset of T cells, predominantly Helper T cells. These cells are integral to the human immune system. CD4 enables T cells to identify and react to antigens by interacting with major histocompatibility complex (MHC) class II molecules, thereby triggering T cell activation and initiating an immune response. Moreover, CD4 serves as the primary receptor for HIV to enter human cells, which exhibits significant importance in the diagnosis and treatment of HIV/AIDS. The CD4+ T cells are crucial regulators within the immune system, tasked with the elimination and control of various infections and the defense against invading pathogens, constituting a vital component of human immune defense mechanisms.
