Anti-CD8 antibodies can inhibit or enhance peptide-MHC class I (pMHCI) multimer binding: this is paralleled by their effects on CTL activation and occurs in the absence of an interaction between pMHCI and CD8 on the cell surface.
Cytotoxic T lymphocytes recognize short peptides presented in association with MHC class I (MHCI) molecules on the surface of target cells. The Ag specificity of T lymphocytes is conferred by the TCR, but invariable regions of the peptide-MHCI (pMHCI) molecule also interact with the cell surface gly...
