In this video, we look at T lymphocytes and cell-mediated immunity. First we explore the structure of T lymphocytes including the T cell receptor. We then look at the four situations where a body cell can express antigens on its surface that can interact with the T cell receptor. Finally, we explore the roles of T helper cells, cytotoxic T cells and T regulator cells in cell-mediated immunity.
