Explanation:
Detailed explanation-1: -First discovered in 1957 by Issac and Lindeman, interferons are noted for their ability to interfere with viral replication. Interferons act via autocrine and paracrine pathways to induce an antiviral state in infected cells and in neighboring cells containing interferon receptors.
Detailed explanation-2: -Interferons are named for their ability to “interfere” with viral replication by protecting cells from virus infections.
Detailed explanation-3: -The interferon system is the first line of defense against viral infection in mammals. This system is designed to block the spread of virus infection in the body, sometimes at the expense of accelerating the death of the infected cells.
