Background

IFN beta is a member of type I family of interferons. It binds to the IFNα/β receptor (IFNAR), activating the Jak/ STAT pathway. Activation of this signaling pathway results in upregulating genes that inhibit viral infection and regulate MHC class I antigens. It is primarily produced by fibroblasts and monocytes. In addition to inhibiting viral infection, IFN beta is also involved in regulating and activating immune response against bacteria, parasite and tumor cells. Multiple sclerosis is characterized by a deficiency of IFN beta 1. An injectable form of IFN beta 1 is used for MS treatment (PMID: 22222875; 29258190; 8602746; 8469318).
