What is the main role of helper T cells in the adaptive immune response?
Answer and explanation
Correct answer: A. They release cytokines that stimulate B cells and cytotoxic T cells to divide
- Step 1: A helper T cell is activated by an antigen-presenting cell.
- Step 2: It then releases cytokines that coordinate B cells and cytotoxic T cells, so it directs rather than kills.
Answer
release cytokines that stimulate B cells and cytotoxic T cells.
Why not the others: Perforin is used by cytotoxic T cells; antibody secretion is by plasma cells; engulfing and presenting is by antigen-presenting cells.
