TLR7 and Salmonella Infections: There were also a number of genes/pathways that had not been linked to Salmonella infections, including regulation of cellular cholesterol (HMGCR and NPC1), calcium trafficking (ATP2A2 and ITPR3), glycosaminoglycan metabolism (B3GNT1, B3GALT6, and HS6ST2), intracellular endosomal trafficking (CLTCL1), and various signaling ligands/receptors (PDGFB, CD27, TLR2, TLR7, EFNB3, GRM5, CHRM2, and FDG1).
