Question

Which one of the following is mismatched?

विकल्प

• Helper T-cells – help complement react

• Memory T-cells – long-living line of T-cells

• Suppressor T-cells – shut down the immune response

• Cytotoxic T-cells – active in tissue rejection

Answer 1

Helper T-cells – help complement react

Explanation:

• Helper T-cells primarily stimulate antibody production by B-cells and enhance macrophage activity through lymphokines but are not directly involved in helping complement react.
• Memory T-cells are indeed long-lived T-cells that provide a quicker response on subsequent antigen exposure.
• Suppressor (or regulatory) T-cells shut down or modulate the immune response to prevent over-activation.
• Cytotoxic T-cells are active in tissue rejection by killing infected or foreign cells.
