Background: 

For more information on Mouse IFN Alpha subtype nomenclature click here.

Most mammalian species have multiple IFN-alpha subtypes. Although the reasons for these multiple subtypes are not fully known, there are clear cell type and temporal differences in their expression. A recent study established a nomenclature for the mouse IFN-alpha subtypes (van Pesch, et al. 2004) and determined relative activities of the subtypes with protein quantification by phosphorimaging of metabolically-labeled protein. In this study, Mouse IFN-alpha A was deemed to have average antiviral activity when compared with the potency of the other subtypes.

Mouse IFN-alpha A was initially cloned by Daugherty, et al. (1984) J. Interferon Res. 4(4) 635]. Being the first commercially available Mouse IFN-alpha protein, it has been used extensively in published research reports. Expression of this subtype has been observed in neurons infected with Theiler’s virus [Delhaye, et al. (2006) PNAS 103(20)7835]. Additionally, the protein has been shown to sensitize lymphocytes to undergo apoptosis [Cuerro, et al. (2004) J. Exp. Med. 200(4)535] and enhance the proliferation and differentiation of CD8 T-cells [Curtsinger, et al. (2005) J. Immunol. 174(8) 4465]. Furthermore, it was used to determine that B10.Q/J mice are susceptible to infection due to a Tyk2 mutation [Shaw, et al.(2003) PNAS 100(20)11594]. Hardy, et al. [Genomics (2004) 84:331] recently suggested a name of IFN Alpha 3 based on sequence comparison of the Mouse IFN-alpha subtype family of proteins.
