  • Description: Interferon-alpha (IFN-a) is a type I interferon, produced by virus-infected cells, and is released as a soluble factor to initiate antiviral responses. IFN-a2 is the most potent IFN-a used in fundamental research and in most clinical applications. The best-known IFN-a2 subvariants, 2A and 2B, differ by only one or two amino acids at positions 23 and/or 34 of the mature protein. Type I IFNs exert potent antitumor activity by increasing the cytotoxic activity of NK and T cells, as well as by inhibiting the proliferation of cancer cells. Additionally, it has been shown that proinflammatory IFN-a modulates the function of B cells in patients with systemic lupus erythematosus, and pegylated forms of IFN-alpha 2A and 2B have implications in the treatment of hepatitis C.
