WebMeaning of Interferons: Interferons are natural glycoproteins produced by virus-infected eukaryotic cells which protect host cells from virus infection. They were discovered by Isaacs and Lindenmann in 1957 in course of a study of the effect of UV-inactivated influenza virus on chick chorioallantoic membrane kept in an artificial medium.
