Once cytotoxic T cells are produced, which of the following is/are consistent with their ability to attack intracellular viruses?

A) Most nucleated cells process antigens through the MHC class I mechanisms.
B) Viral antigens are processed by the MHC class I mechanism and are presented to the cell surface.
C) Cytotoxic T cells bind to MHC class I processed antigens.
D) Cytotoxic T cells bound to the MHC class I processed antigens release lymphokines.
E) All of the choices are correct.

Cytotoxic T cells recognize and attack infected cells by binding to viral antigens presented on the cell surface via MHC class I molecules. All nucleated cells present antigens through MHC class I mechanisms, allowing cytotoxic T cells to target cells infected with intracellular pathogens, including viruses. Upon recognition, cytotoxic T cells release substances like perforin and granzymes (rather than lymphokines, which are more commonly associated with helper T cells) to kill the infected cells, but the overall process described is consistent with their function.
