T cells are a subset of lymphocytes that play a large role in the immune response.
The abbreviation "T" stands for thymus, the organ in which their final stage of development occurs.
Every effective immune response involves T cell activation; however, T cells are especially important in cell-mediated immunity, which is the defense against tumor cells and pathogenic organisms inside body cells.
