Question 1 of 1
Some viruses have mechanisms to down-regulate MHC class I protein expression on the surface of cells in which the virus is replicating. This immune evasion strategy might prevent effector CD8 cytotoxic T cells from recognizing and killing the virus-infected cells. Would this immune evasion strategy also prevent the initial activation of virus-specific CD8 T cells?
Correct Answer: B
Rationale: DCs cross-present viral peptides , bypassing evasion; not all cells (A,
D) or early presentation explain activation.
