Background
Interferon beta (IFN-beta ), also known as fibroblast IFN, is a secreted, approximately 22 kDa member of the type I interferon family of molecules (1). Mature mouse IFN-beta shares 75% and 47% amino acid sequence identity with the rat and human proteins, respectively. Fibroblasts are the major producers of IFN-beta , but it can also be produced by dendritic cells, macrophages, and endothelial cells in response to pathogens (2). It is transcriptionally regulated by TRAF3, IRF3, IRF7, and NF-kappa B (3, 4). IFN-beta -deficient mice show increased susceptibility to experimental autoimmune encephalomyelitis (EAE), a disease model of human multiple sclerosis (MS) (5). Furthermore, IFN-beta has been shown to suppress the Th17 cell response in both MS and EAE and has commonly been used as a treatment for MS (6-10). IFN-beta can additionally induce the expression of the anti-inflammatory cytokine IL-10 (11).

STING in Innate Immunity and Cancer: What’s the Buzz About? STING (STimulator of INterferon Genes protein) acts as a sensor of cytosolic DNA. Bacteria/Virus or self-derived DNA in the cytosol activates the STING pathway and promotes the production of type I interferons (IFN-alpha and IFN-beta). STING also ... Read full blog post.
