TYPES OF T CELLS H ELPER  T  CELLS ---these are of major importance to the immune response. By releasing cytokines,  they: Induce the formation of cytotoxic T cells Activate macrophages Stimulate B cells to form antibodies   These are the steps in activation of T cells:       1) A macrophage or dendritic cell takes in the antigen and processes it. The antigen is broken  into bits, and some of the bits are combined with cellular proteins called MHC proteins. The  combination of antigen/MHC protein starts to leave the cell by exocytosis, but remains stuck to  the outside surface of the plasma membrane. The macrophage or dendritic cell is now an antigen- presenting cell (APC).       2) A CD4+ T cell specific to the antigen binds to the antigen-MHC complex on the APC
