KIR2DL4 and infection: Infection with both, RVC and G9P[13] significantly modulated the expression of genes encoding a family of polypeptide N-acetylgalactosamine (GalNAc) glycosyltransferases responsible for the biosynthesis of Tn antigen (GALNT family)—initiation of mucins glycosylation—addition of GalNAc to serine or threonine.
