T cell
T cells or T lymphocytes are a type of lymphocyte (in turn, a type of white blood cell) that plays a central role in cell-mediated immunity. They can be distinguished from other lymphocytes, such as B cells and natural killer cells (NK cells), by the presence of a T-cell receptor (TCR) on the cell surface. They are called T cells because they mature in the thymus (although some also mature in the tonsils). The several subsets of T cells each have a distinct function. The majority of human T cells rearrange their alpha/beta T cell receptors and are termed alpha beta T cells and are part of adaptive immune system. Specialized gamma delta T cells, which comprise a minority of T cells in the human body (more frequent in ruminants), have invariant TCR (with limited diversity), can effectively present antigens to other T cells and are considered to be part of the innate immune system.
