Immature T-cells are formed in the bone marrow, just like any other blood cells, through the process of hematopoiesis. These immature T cells are then transported to the thymus where they mature and differentiate into the different types of T cells; cytotoxic, helper and regulatory. T-helper cells, also called CD4⁺ cells, are important in activating B-cells and T-cytotoxic cells in case of infection.
