Accepted Answer

When an antigen is bound to a Class I MHC molecule, it can stimulate a cytotoxic T cell. Class I MHC molecules are found on almost all nucleated cells, and their role is to present intracellular antigens to cytotoxic T cells. Cytotoxic T cells can recognize and destroy cells that are infected with viruses or have become cancerous.
