Which of the following is NOT TRUE about interferons?
Correct answer: D. Secrete interleukin
- A. Belong to cytokines
- B. Activate natural killer cells
- C. Activate immune cells
- D. Secrete interleukin
Explanation
Interferons (IFNs) are a broad class of cytokines that are part of your natural defenses. They tell your immune system that germs or cancer cells are in your body. And they trigger killer immune cells to fight those invaders. Interferons got their name because they "interfere" with viruses and keep them from multiplying.

About Specific Defense Mechanism
Specific defense mechanisms provide targeted immunity through B lymphocytes, T lymphocytes, antibodies and memory cells that recognize particular antigens. Questions cover humoral and cell mediated responses, clonal selection, primary and secondary immune responses, vaccination and passive immunity, while distinguishing adaptive defenses from the immediate, non specific innate response.
