Title: Interferon-a
Additional Names: Alfa-interferon; alpha-interferon; IFN-a; LeIF; leukocyte interferon; lymphoblastoid interferon
Literature References: Cytokine with antiviral, antiproliferative, and immunomodulatory activity. Produced by leukocytes stimulated by virus, bacteria, or protozoa as part of the immune response; artificially induced by double-stranded RNA. Inhibits protein synthesis and viral replication; enhances cytotoxic activity. Multiple subtypes have been identified which contain ~166 amino acids and are variably glycosylated; mol wt 16-27.5 kDa.
