Also called T cell and thymocyte, T lymphocyte is a type of white blood cell which helps control immune responses. It develops from stem cells in the bone marrow and later moves to the thymus where it matures. T lymphocytes are of two types killer cells and helper cells. The killer T cells are specialized in attacking viruses and sometimes also bacteria. They may also help fight cancer. Helper T cells are the main regulators of the immune response. They activate killer T cells and B lymphocytes.
