Question
Differentiate between T-helper cells and T-killer cells.
✓
Answer
Differences between T-helper cells and T-killer cells :
| S.No. | T-Helper cells | T-killer cells |
| 1 | These cells secrete interleukins and activate T-killer cells and sensitized T-cells. | Whereas these cells, after coming in contact with the micro-organism, secrete a cytotoxic substance directly from the body of the micro-organism and destroy it. |
| 2 | These stimulate macrophages to perform cytophagic action. AIDS virus paralyzes the immune system by inactivating or destroying these cells. | These killer cells also consume tissue cells infected with viruses. |
