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.
T-cells are essential for human immunity. The devastating effects of a lower than normal number of just one type of T-cell are all too evident in HIV/AIDS. There are several different kinds of T-cell; broadly speaking they can be divided into two different types, killer T-cells and helper T-cells. Killer T-cells have âX-ray visionâ as they are able to see inside our bodies own cells simply by scanning their surface.
