Natural killer cells (NK cells) are a subset of non-B, non-T peripheral blood lymphocytes that appear to play a crucial role in the human innate immune response. The function of NK cells is important for the clearance of tumor cells, for the removal of immunoglobulin-bound antigens, and for the control of viral infections. NK function has been reported to be decreased in certain individuals, including those with primary immunodeficiencies, those with late-stage human immunodeficiency virus infections, and pregnant women.
