Vedclass · Answer

(A) Interferons $(IFNs)$ are a group of signaling proteins made and released by host cells in response to the presence of several viruses.They belong to the class of glycoproteins known as cytokines.When a cell is infected by a virus,it secretes interferons,which induce an antiviral state in neighboring uninfected cells,thereby preventing further viral replication.Thus,they are classified as antiviral proteins.
