IL6 and diabetes mellitus: Furthermore, plasma levels of several proteins (e.g., IL-18R1, IL-6, and OPG), lipids (e.g., DGs/TGs), and nonlipid metabolites (e.g., 2-methylguanosine, xanthopterin, N4-acetylcytidine, glycocholic acid, PAGln, and IMP) that were positively associated with diabetes were elevated in PLWH in our and other studies [42, 76–78].
