Question

Cytokines that provides non specific immunity against virus are
A. Interleukin
B. Tumour necrosis
C. Colony stimulating
D. Interferon

Answer 1

Hint: The immune system is the defense system of a host which carries many biological structures and processes within the system that protects against disease. Immunity systems are two types: the innate immune system and the adaptive immune system. These two carried their function by humoral immunity and cell-mediated immunity.

Complete Answer:
- Innate immune system is also known as non specific immunity because the response of this is non specific.
- Non-specific immunity, or innate immunity, is the immune system which is present from birth and made up of phagocytes and barriers. It is triggered by when any virus is present in the body.
- The adaptive immune system is also understood as the acquired immune system which is defined as an immune system that consists of specialized, systemic cells and helps to stop the growth of foreign particles.
- Interferons are the group of proteins which help in signaling in the presence of viruses. Formation and release of interferons take place by host cells.
- A virus infects the cell and causes the release of interferons to increase the antiviral defense mechanism of the body. IFNs come under the large class of proteins known as cytokines.

So, the correct answer is Interferons.

Note: Cytokines are the molecules used for communication between cells or send the signal to start the protective defenses of the immune system.
