GlossaryNatural Killer Cells

cells that destroy virus-infected or cancerous cells

Natural Killer Cells, often abbreviated as NK cells, are a type of white blood cell that plays a crucial role in the body's immune system. They are part of the innate immune response and are responsible for identifying and destroying cells that are infected by viruses or have become cancerous, without the need for prior exposure to these threats.
