So mitosis of the cell takes place and we form many of these cloned helper T cells. And these clone helper T cells begin to release another group of cytokines. And these cytokines go on. And then these cytokines induce these B Lymphocytes and T Lymphocyte cells to basically mature and differentiate into even more specialized cells. So these B Lymphocytes basically produce plasma cells as well as memory cells. While the T cell, when it reacts with the cytokines, it produces cytotoxic T cells, also known as killer T cells.
