Natural Killer Cell Activation

Molecular classification: Cellular process, Receptor-mediated signaling

Overview

Natural killer cell activation is a complex but highly regulated process central to innate immunity. It relies on an intricate interplay between multiple surface receptors—both activating and inhibitory—and their downstream signaling partners. The ultimate effect is rapid recognition and elimination of abnormal host targets while sparing healthy tissue through robust self-tolerance mechanisms maintained by continuous integration of these opposing signals.
