Cytotoxic T cells induced by infection with virus A will kill target cells
Correct Answer: Infected by virus A and identical at class I MHC loci to the cytotoxic T cells
Description: The CD8+ cytotoxic T cells have antigen specific T-cell receptors (TCR) on their membranes that will recognize and bind to self class I antigens. Since the viral peptides are presented as a complex with the self class I antigens, the CD8+ cells can now recognize and react to the virus A peptides. Remember that class I antigens are expressed on all nucleated cells and platelets. Ref: Levinson W. (2012). Chapter 58. Cellular Basis of the Immune Response. In W.
