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-α21 (interferon α 21) belongs to type 1 interferon family.  IFN- 21 is produced by macrophages, IFN-alpha have antiviral activities. Interferon stimulates the production of two enzymes: a protein kinase and an oligoadenylate synthetase. Belongs to the alpha/beta interferon family.
