IFNA1 and Salmonella Infections: For this analysis, we assessed the relative transcript levels of cytokine and interferon (IFN) system genes known to be induced during Salmonella infection including; the type I IFN system gene, IFN-β [50], [53]; the inflammatory and acute phase response genes, interleukin-1 beta (IL-1β) and IL-6 [53], [73]–[76]; inducible nitric oxide synthase (iNOS), a known target of IFN and cytokine signaling required for resistance to Salmonella infection [53], [77]–[79]; and IL-10, an inhibitory modulator of the inflammatory response [74], [75], [80], [81].
