Cytotoxic or killer T cells (CD8 marker)participate directly in the destruction of antigens by binding to and altering the intracellular environment,which ultimately destroys the cell.Killer cells also release cytotoxic substances into the antigen cell that cause cell lysis.Killer T cells additionally provide the body with immunosurveillance capabilities that monitor for abnormal cells or tissue.This mechanism is responsible for the rejection of transplanted tissue and the destruction of single malignant cells.Helper T cells (also known as T4 cells because they carry a CD4 marker)enhance the humoral immune response by stimulating B cells to differentiate and produce antibodies.Suppressor T cells downgrade and suppress the humoral and cell-mediated responses.
