NK cells exhibit broad-spectrum anticancer effects via various mechanisms, including antibody-dependent cell-mediated cytotoxicity (ADCC) via CD16 binding, secretion of cytokines (IFN-γ, TNFα), release of cytolytic granules (e.g., granzyme B), and expression of death ligands. The balance of NK cell activity is regulated by activating and inhibitory receptors.
