 Using the mechanisms outlined below the virus stimulates the production of interferons and other cytokines that provide protection against viruses.The main component of innate antiviral response is type I interferons (IFNs) production and most cells can produce type I IFNs, including IFN-α and -β.The recognition by cellular molecules that are called pattern recognition receptors (PRR) of triggering viral elements, such as the virus genomic RNA, the replication intermediary double-stranded RNA, or the viral ribonucleoproteins, promotes IFN production and response pathways.
