Which of the following statements is correct about the development of T cells? O After many cell generations, some of the CD8+ T cells differentiate into at least six functional phenotypes. - T cells differentiate into progenitor cells destined to become (1) natural T regulatory (Treg) cells, (2) natural killer T (NKT) cells, (3) gamma/delta T cells, and (4) alpha/beta T cells. Activation by its specific antigen causes a T helper cell (TH) cell to mature into a cytotoxic T lymphocyte (CTL) that functions to destroy host cells that have been infected by intracellular pathogens, such as a virus, or have altered MHC surface proteins. T cells originate from CD34+ stem cells in the bone marrow, where they also mature.

Figure 42.11 Which of the following statements about T cells is false? Helper T cells release cytokines while cytotoxic T cells kill the infected cell. Helper T cells are CD4+, while cytotoxic T cells are CD8+. MHC II is a receptor found on most body cells, while MHC I is a receptor found on immune cells only.
