• When the immune system is activated due to the viral infection or other immune response the white blood cells in our body produces Interferons (are a group of proteins called cytokines).
• The name of the interferons comes from their ability to interfere with the production of new virus particles. Interferons do not directly kill viral or cancerous cells; they boost the immune system response and reduce the growth of cancer cells by regulating the activity of several genes that control the secretion of numerous cellular proteins that affect growth.
• Hence Interferon suppresses the pathogenic activity of Viruses.
• So, the correct answer is 'Viruses'.

• Hence a cell coded protein formed in response to infection with most animal viruses is interferon.
• So, the correct answer is 'Interferon'.

Penicillin-antibiotic.

• When the immune system is activated due to the viral infection or other immune response the white blood cells in our body produces Interferons (are a group of proteins called cytokines). Interferons suppress the viral multiplication.
• The name of the interferons comes from their ability to interfere with the production of new virus particles. Interferons do not directly kill viral or cancerous cells; they boost the immune system response and reduce the growth of cancer cells by regulating the activity of several genes that control the secretion of numerous cellular proteins that affect growth.
• Hence interferons suppresses the pathogenicity of viruses.
• So, the correct answer is 'Viruses'.

• Interferons are a group of signalling proteins made and released by host cells in response to the presence of several viruses. Generally, a virus-infected cell will release interferons causing nearby cells to make their anti-viral defences.
• A paratope also called an antigen-binding site or Fab. It is a part of an antibody which recognizes and binds to an antigen. It is a small region of the antibody containing the antibody's heavy and light chains.
• Interleukins (ILs) are a group of cytokines (secreted proteins and signal molecules) that were first seen to be expressed by white blood cells (leukocytes).
• Histamine is an organic nitrogenous compound involved in local immune responses, as well as regulating physiological function in the gut and acting as a neurotransmitter for the brain, spinal cord, and uterus. Histamine is involved in the inflammatory response and has a central role as a mediator of itching.
• So, the correct answer is 'a-iii,b-i,c-iv,d-ii'.

Interferons are glycoproteins produced by cells in response to viral infections and are now produced using recombinant DNA technology (genetic engineering) for therapeutic use.

Interferon is the name given to a group of proteins known primarily for their role in inhibiting viral infections and in stimulating the entire immune system to fight disease. Research has also shown that these proteins play numerous roles in regulating many kinds of cell functions. Interferons can promote or hinder the ability of some cells to differentiate, that is, to become specialized in their function. They can inhibit cell division, which is one reason why they hold promise for stopping cancer growth. Recent studies have also found that one interferon may play an important role in the early biological processes of pregnancy. Although once thought to be a potential cure-all for a number of viral diseases and cancers, subsequent research has shown that interferons are much more limited in their potential.
