More Information
Natural killer cells are a vital part of the body's innate immune response. Unlike adaptive immunity, which requires prior exposure to a pathogen, innate immunity provides a non-specific, immediate defense. NK cells are especially efficient at identifying and destroying virally-infected and tumorous cells.
