Natural killer cell - Wikipedia
Natural killer cells, also known as NK cells, are a type of cytotoxic lymphocyte critical to the innate immune system. They are a kind of large granular lymphocytes [1] [2] (LGL), and belong to the rapidly expanding family of known innate lymphoid cells (ILC) and represent 5–20% of all circulating lymphocytes in humans.

2008年8月1日 · Natural killer (NK) cells were discovered more than 30 years ago. NK cells are large granular lymphocytes that belong to the innate immune system because unlike T or B lymphocytes of the adaptive or antigen-specific immune system, NK cells do not rearrange T-cell receptor or immunoglobulin genes from their germline configuration.

Human natural killer cells: Form, function, and development
2022年4月22日 · Natural killer (NK) cells are commonly described as being “innate immune effector cells that can lyse virally infected and tumorigenic cells without prior antigen sensitization.” 1-3 This fundamental description arises from the properties first attributed to NK cells following their discovery almost 50 years ago.
Natural Killer Cells: Structure, Function, and Immune Surveillance
2025年1月9日 · Natural killer (NK) cells are integral to the body’s immune surveillance system, constantly patrolling for signs of infection or cellular abnormalities. Their primary function is to monitor and eliminate cells that exhibit signs of stress or transformation, such as tumor cells or those infected by viruses.
