42.1 Innate Immune Response2 Homework – Unanswered. Due in 4 days Which is true of interleukins and interferons? A interleukin is a cytokine, while interferon is an enzyme they both are found on the surfaces of pathogens, however interleukins are located within the phospholipid bilayer of external cell membranes while interferons are externally attached to cell membranes via a stalk-like structure, allowing them to play a defensive role O C they both are released by pathogens, helping pathogens overcome the host immune system inteferon forms a physical barrier that prevents pathogens from entering the body while interleukin attacks pathogens found between cells interferon reduces protein synthesis in virus infected cells while interleukins can help mediate interactions among immune cells, allowing a more effective response to pathogens Unanswered 1 attempt left - Submit

Answer 1

E- TRUE . Interferon reduces protein synthesis in Virus infected cells while Interleukins can help mediate interactions among immune cells, allowing a moe effective response to pathogens.

Interferons are host coded proteins produced by host cells in response to sevseral viruses. Interferons belongs to Cytokines,which are peptide mediators that regulate immunological response. On exposure to interferon cells produce a translating inhibiting protein,TIP which selectively inhibits translation of viral mRNA, without affecting cellular Mrna.

Interleukin  are group of Cytokines with anti-inflammatory properties which regulate immune response of host against pathogen.Interleukin communicate between cells. Interleukin are divided into different groups based on structural properties. Interleukin1(IL1) is principally produced by macrophages and monocytes,production is stimulated by antigens,toxins,injury and inflammtory processes and inhibited by cyclosporin A, corticosteriods and prostaglandins.

A. False. Interluekins are cytokines and Interferons are group of proteins released by host cells in response to viruses and are not enzymes.

B.False. Interleukins and interferons are produced by host cell. They are releasd by activated T-lymphocytes.

C.False. Interferons and Interleukins are produced by host cell in response to pathogen in cellular immune mechanism, not by pathogen.

D.False. Interferons reduces protein synthesis in virus infected cells and interleukin regulate host cell inflammtory and immune response.
