Type I IFN(IFN-alpha and IFN-beta) is the first responder against animal virus infections.When virus infects,the virus could be recognized by the pathogen-associated molecular pattern receptors and leads to the transcription of IFN-beta.Then,IFN-beta binds to the IFN-alpha/beta receptor,initiating the phosphorylation of STAT1 which induced the activation of the genes containing interferon-stimulated response element (ISRE) in their promoters and resulted in transcriptional up-regulation of these genes and establishment of an antiviral state.
