Background: IFN-alpha 13

Interferon-alpha 13 (IFN alpha-13), also known as IFN alpha-1/13 and LeIF D, is one of 14 subtypes within the IFN-alpha family (1). Interferons are a family of cytokines with potent antiviral, antiproliferative and immunomodulatory properties, classified based on their binding specificity to cell surface receptors (1). The members of the IFN-alpha family are distinct but closely related proteins sharing approximately 80% amino acid (aa) sequence identity and a globular structure composed of five alpha-helices (1-3). The mature extracellular domain (ECD) of mouse IFN alpha-13 is shares 64% aa sequence identity with human IFN alpha-13. IFN-alpha family members signal through a common set of cell surface receptor complex composed of IFN alpha-R2 and IFN alpha-R1 subunits (2). Individual IFN-alpha subtypes are known to display unique efficacies to viral protection, and IFN alpha-13 displays antiviral activity protective against Theiler's virus, Mengo virus, VSV (4). IFN alpha-13 reproducibly appears to be up-regulated in response to TMEV infection (5). IFN alpha-13 also protects L929 cells against EMCV as tested in our assays.
