They are generally CD8 +, which makes them MHC class I restricted. CTLs are able to eliminate most cells in the body since most nucleated cells express class I MHC molecules.
WebWhen a cytotoxic T cell (CTL) recognizes a peptide presented in the MHC-1 of a dendritic cell (APC), why it doesn't kill this cell? I know that initially, in the lymph node, the T cell is inactivated. But eventually it becomes activated and travels to the tissue, where it again finds APCs presenting the offending antigen.
