ABSTRACT
Natural killer (NK) cells represent a critical component of the innate immune system with potent anti-tumor capabilities. These cytotoxic lymphocytes provide rapid, MHC-unrestricted responses against malignant cells, making them attractive candidates for cancer immunotherapy. This review explores the fundamental biology of NK cells, their role in cancer surveillance and elimination, mechanisms of tumor evasion, and the rapidly evolving landscape of NK cell-based therapeutic strategies. We discuss current clinical applications, emerging technologies including chimeric antigen receptor (CAR)-NK cells, and future directions in harnessing NK cell biology for oncological treatment.
