What Does NK Stand For?

NK stands for Natural Killer

NK, or Natural Killer, refers to a type of lymphocyte in the immune system that plays a critical role in the body’s defenses against tumors and viral infections. NK cells are characterized by their ability to recognize and eliminate infected or malignant cells without prior sensitization. They are essential for maintaining immune homeostasis and contribute to the early stages of the immune response by producing cytokines and cytotoxic granules to induce cell death in targeted cells. Their unique functionality makes them a focus of research in immunotherapy and infectious disease treatment.
