-Innate immunity mechanism for eradicating established viral infection

Question

Quizplus · Accepted Answer

Natural killer (NK) cells are innate immunity effector cells that can kill infected cells by mechanisms similar to cytotoxic T lymphocytes (CTLs)
However, they are activated by different receptors than are CTLs, and they are inhibited by receptors that bind class I MHC on other cells
Viruses have the ability to evade detection by CTLs by inhibiting class I MHC expression on their host cell surfaces
When this occurs, NK cells may provide a backup defense mechanism, since they are activated by host cells that lack normal class I MHC expression.
