Regarding MxA, it is known that MxA proteins, amongst many other proteins, also possess antiviral properties: in case of certain viral infections, such as influenza and measles, MxA mRNA and MxA protein are rapidly upregulated by endogenous interferon type I and play a role in the inhibition of multiplication of these viruses (16, 25). This evidence concerns the gene MX1 and viral infectious disease.
