A cytotoxic T cell (also known as TC, cytotoxic T lymphocyte, CTL, T-killer cell, cytolytic T cell, CD8+ T-cell or killer T cell) is a T lymphocyte (a type of white blood cell) that kills cancer cells, cells that are infected (particularly with viruses), or cells that are damaged in other ways.
The University of Virginia states that phagocytosis is a major tool of destroying pathogens in the body, but the phagocytic leukocyctes do not work in isolation. They are aided by the lymphocytes, which are b-cells and t-cells. These cells, which compose between 20 percent and 45 percent of leukocytes, are capable of marking pathogens so that the phagocytic leukocytes can know what to envelop and destroy.
