cytotoxic T cells

Cytotoxic T cells, also known as killer T cells, are a type of white blood cell that plays a crucial role in the immune system. Their main job is to identify and destroy infected or cancerous cells in the body. They do this by recognizing specific markers on these cells and releasing substances that can kill them. This process helps protect the body from diseases and infections. Cytotoxic T cells are essential for maintaining health, particularly in responding to viral infections and preventing cancer from spreading.
