Cytotoxic T lymphocyte

Cytotoxic T lymphocytes (CTLs) are a type of white blood cell that play a crucial role in the immune system. They specifically target and kill infected or cancerous cells in the body. When CTLs recognize harmful cells, they release substances that destroy those cells, helping to prevent the spread of illness. Their action is essential for maintaining health and combating diseases like viruses and tumors. Essentially, cytotoxic T lymphocytes act as the body's defense team, identifying and eliminating threats to keep us healthy.
