Question

According to the cellular immune response table, which T-cell type both activates and regulates immune response by stimulating B-cells and activating macrophages?

Options

• Memory T-cells

• Cytotoxic T-cells

• Suppressor T-cells

• Helper T-cells

Answer 1

Helper T-cells are responsible for activating and regulating immune responses by stimulating B-cells to produce antibodies and by activating macrophages through lymphokines. This regulatory role makes Helper T-cells central coordinators of the immune system, connecting cellular and humoral immunity.
