IMMUNOLOGY

Detailed explanation-1: -Upon activation and recruitment to the site of infection, NK cells employ three main strategies to kill virally infected cells: the production of cytokines, the secretion of cytolytic granules, and the use of death receptor-mediated cytolysis [8].

Detailed explanation-2: -First, use of NK cells will bypass the need of antigen-specific T cells. Second, NK cells can directly kill tumor cells and can also rapidly secrete proinflammatory cytokines that can potentiate the adaptive immune response (128).
