Background
CD8α (Cluster of differentiation 8 alpha) belongs to immunoglobulin superfamily and mediates MHC-I recognition and cytotoxic T-cell activation. CD8α forms heterodimer with CD8β and is predominantly expressed on cytotoxic CD8⁺ T lymphocytes as well as subsets of NK cells. Acting as a co-receptor, it binds MHC-I-peptide complexes on target cells, stabilizes TCR-MHC interaction and recruits Lck tyrosine kinase to amplify TCR signaling. This drives CTL proliferation, granzyme-perforin release and target-cell killing.
