Background：T-cell surface glycoprotein CD4 is also known as T-cell surface antigen T4/Leu-3.
CD4 contains three Ig-like C2-type (immunoglobulin-like) domains and one Ig-like V-type (immunoglobulin-like) domain.
CD4 is accessory protein for MHC class-II antigen/T-cell receptor interaction.
CD4 induces the aggregation of lipid rafts.
CD4 is a primary receptor used by HIV-1 to gain entry into host T cells.
HIV infection leads to a progressive reduction of the number of T cells possessing CD4 receptors.
Therefore, medical professionals refer to the CD4 count to decide when to begin treatment for HIV-infected patients.
