How do cd8 t cells get activated
WebNational Center for Biotechnology Information WebCD8+ T cells are primarily activated by the interaction of their T cell receptor with major-histocompatibility complex (MHC)-I bound peptide antigens. Every nucleated cell can express MHC-I on their surface and present antigens to CD8 + T cells.
