T lymphocytes (T cells) are a type of white blood cell that is vital for the function of cell-mediated immunity. Once it is produced in the Thymus, naive T cells enter the bloodstream and migrate towards the lymphoid tissue until they are in contact with their specific antigen. Once it binds to the target cells, T lymphocytes begin to proliferate and differentiate into cells i.e. armed effector T cells for the removal of the antigen [1].
