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.

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4月18日 · Natural killer (NK) cells are effector lymphocytes of the innate immune system that control several types of tumors and microbial infections by limiting their spread and subsequent tissue...

2021年4月29日 · Natural killer cells (NK cells) are lymphocytes of the innate immune system. These white blood cells belong to the same family as B cells and T cells and play an important role in limiting the spread of infection.

2025年1月9日 · Natural killer (NK) cells are a component of the innate immune system, known for their ability to target and eliminate virus-infected and cancerous cells without prior sensitization. Their capability to distinguish between healthy and abnormal cells makes them essential in maintaining bodily health.

Natural killer (NK) cells are a type of cytotoxic lymphocyte critical to the innate immune system. They provide rapid responses to viral-infected cells and tumor formation, acting at around 3 days after infection.

2023年2月6日 · Natural Killer cells represent the third lymphocyte population (Following T and B cells), and they play essential roles in the frontline's defense of the innate immune system. The term natural killer suggests that these cells can kill the target cells without pre-stimulation.

2022年4月28日 · Natural killer (NK) cells are a group of innate lymphocyte cells with cytolytic activity against virus-infected cells and physiologically stressed cells like tumor cells. Initially, NK cells were described as larger granular lymphocytes with cytotoxic activity against tumor cells.
