Explanation:
Detailed explanation-1: -CD4 and CD8 co-receptors on the surface of T cells. Cytotoxic T cells (TC) express CD8, which recognizes class I MHC proteins, whereas helper T cells (TH) express CD4, which recognizes class II MHC proteins.
Detailed explanation-2: -The CD antigens are a diverse group of surface glycoproteins with a multitude of functions, providing the interface between a cell and the external environment that includes other cells. The CD antigens may be cell-cell or cell-matrix adhesion molecules, cytokine receptors, ion pores, or nutrient transporters.
