Best Answer: All T cells originate from hematopoietic stem cells in the bone marrow.T cells belong to a group of white blood cells known as lymphocytes and play a central role in cell-mediated immunity.
A answered. Lymphocytes are different from other types of white blood cells because they recognize and remember invading bacteria and viruses. T lymphocytes, or T cells, are responsible for cell-mediated immunity. T cells come in many types with specific functions, including: Helper T cells direct the immune system. In a rather lengthy process, helper T cells release cytokines. Cytokines stimulate B cells to form plasma cells. Plasma cells form antibodies, which stimulate the production of two other types of T cells: cytotoxic T cells and suppressor T cells. Helper T cells are the cells attacked by the AIDS virus. You can imagine the devastating effect of destroying the T cells that direct the immune system. Cytotoxic T cells release certain chemicals that break open to kill invading organisms.
