自然杀伤细胞(natural killer cell，NK)是机体重要的免疫细胞，不仅与抗肿瘤、 抗病毒感染和免疫调节有关，而且在某些情况下参与超敏反应和自身免疫性疾病的发生，能够识别靶细胞、杀伤介质。

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. [3]

Natural killer cells (NK cells) are white blood cells that destroy infected and diseased cells, like cancer cells. They’re also a type of lymphocyte, like B-cells and T-cells. NK cells can destroy harmful cells in the early stages, preventing viruses and cancer cells from spreading.
