Titration of Mouse Interferon Alpha 4 (Mammalian) in the L929 Cell Line

Mouse IFN Alpha 4 was initially cloned by Zwarthoff et al. [(1985) Nuc. Acids Res. 13(3)791], and has been extensively studied. It is apparently expressed early in viral infection in a protein synthesis independent manner, and its expression is induced by phosphorylation of IRF-3. It may be that Mouse IFN Alpha 4, like IFN Beta, has a priming function on cells, enabling the expression of other Mouse IFN Alpha subtypes [Review by Mesplede et al., (2003) Autoimmunity 36(8):447 and Asselin-Paturel & Trinchieri (2005) J. Exp. Med. 202(4):461]. Thus, this interferon is among the first observed after viral infection. Intriguingly, while this interferon is expressed in a large variety of cell types, one report suggests that the expression level in dendritic cells is low to non-existent [Barchet et al., (2002) J. Exp. Med. 195(4):507].

Summary: Mouse IFN Alpha 4 is a widely expressed mouse interferon alpha which may play a role in preparing cells to express high levels of other mouse interferon alpha subtypes upon viral infection.
