These soluble extracellular proteins or glycoproteins are essential regulators of biochemical processes that occur in the intercellular domains; they help to mobilize cells engaged in innate and adaptive inflammatory host defense mechanisms such as the regulation of NK cell function during viral infection which is regulated by IFNα, IFNβ, IL-12, and IL-15 (Nguyen et al., 2002), cell growth, differentiation, cell death, angiogenesis, as well as developmental and repair processes aimed at the restoration of homeostasis (Oppenheim, 2001). This evidence concerns the gene IFNA1 and viral infectious disease.
