cell with antigen-MHC complex • Helper T cell that binds to the complex • Helper T secretes interleukin that stimulates mitosis in B cells so they multiply • Some B cells mature into plasma cells and other become memory cells • The plasma cells produce antibodies also called immunoglobins – proteins which attach to the antigens
Helper T cells, or Th cells, coordinate immune responses by communicating with other cells. Some stimulate nearby B cells to produce antibody, others call in microbe-gobbling cells called phagocytes, still others activate other T cells. Killer T cells—also called cytotoxic T lymphocytes or CTLs—perform a different function. These cells ...
Students will discover that there are also cells called helper T-cells that tell B-cells to start creating antibodies. These helpers also instruct killer T-cells to attack infected cells. Then memory cells remember the germs that attacked the body.
What specifically results from the release of cytokines by helper T cells? b. What is the problem with helper T cells carrying out this function in HIV infection?
