Influenza virus A infections cause highly contagious, severe respiratory diseases that can be fatal. This virus is an enveloped, segmented, negative stranded RNA virus that belongs to the family Orthomyxoviridae. Infections with influenza A viruses induce a variety of intracellular signaling and gene expression events. Intracellular signaling events include pathways that could be antiviral or proviral in nature. Recent research has identified some of these pathways: MAPK signaling, NF-kappaB signaling, PI3K/AKT signaling and Wnt singaling pathways...
