Cоnsider twо receptоrs, one inhibitory аnd one аctivаting, on the surface of natural killer (NK) cells: KIR receptors that interact with certain class I MHC proteins, and special Fc receptors that recognize IgG antibodies. When NK cells are incubated with an immortalized (i.e. cancerous) B cell line derived by infection of human B cells with Epstein–Barr Virus, the B cells are killed by NK cells. Normal B cells, by contrast, are not efficiently killed by NK cells. In each of the following scenarios, indicate whether the described changes are expected to enhance, suppress or have no effect on the cytotoxicity (killing activity) of the NK cells in this system. Match the prompt with one of these choices.
