Final answer:
CD 8 T cells bind to MHC I receptors that display antigens from intracellular pathogens. These antigens are presented on the surface of infected cells through MHC class I molecules. CD8 is associated with cytotoxic T cells (CTLs), which directly kill infected cells by apoptosis.
Step-by-step explanation:
CD 8 T cells bind to MHC I receptors that display antigens from intracellular pathogens. These antigens are presented on the surface of infected cells through MHC class I molecules.
CD8 is associated with cytotoxic T cells (CTLs), which directly kill infected cells by apoptosis. MHC class I molecules are found on most cells of the body and bind to CD8 molecules on T cells to initiate an immune response.
