what cell turns off the immune response?
Three broad categories of T cells. 1  Helper T cells augment the immune response by recognizing the presence of a foreign antigen and then stimulating antibody production and producing cytokines that âturn onâ or activate other T cells. 2  Regulatory T cells function in an opposite manner: they dampen or turn off the immune response.
