Description
The interferons (IFN)s are a family of cytokines with potent antiviral, antitumor, and immunomodulatory properties. Interferons are increasingly used clinically to treat a range of malignancies, myelodysplasias and autoimmune diseases. Interferons are divided into type I, II, and III. Type I IFNs (IFN-α and IFN-β) are most abundant in number, distribution, and expression.
IFN-α1 (interferon α 1) belongs to type 1 interferon family, and is a lymphoid factor. IFN-α1 interacts with IFNAR1 (interferon α receptor 1) and IFNAR2. The interaction activates JAK1 (janus-activated kinase 1) and tyrosine kinase 2. These events phosphorylate and activate STAT1 and STAT2 (signal transducer and activator of transcription proteins), leading to the upregulation of interferon-stimulated genes some of which encode antiviral proteins.
