Web20 de may. de 2024 · 1 INTRODUCTION. Natural killer (NK) cells are cytotoxic innate lymphocytes that can lyse cancerous or virally infected cells. 1 Their activity is regulated by a variety of germline-encoded receptors that can mediate either activating or inhibitory signals and thereby elicit NK cell responses while also ensuring self-tolerance. NK cells … WebNatural killer (NK) cells are lymphocytes of the innate immune system that are involved in early defenses against both allogeneic (nonself) cells and autologous cells undergoing …
