IFN-α/β binds to its receptor to activate the signalling pathway, involving the activation of the JAK family of protein tyrosine kinases, and STAT and interferon regulatory factor (IRF) families of transcription factors. This event is an essential aspect of the innate immune system. Cells produce large amounts of type I interferons - IFN-α and IFN-β - in response to viral infection, and these interferons elicit strong antiviral activities in target cells.
