Diabetic peripheral neuropathy (DPN) is one of the most common complications of diabetes, but currently no protein biomarkers have been introduced into clinical diagnosis, especially among early-stage diabetic patients. Our previous study in animal model showed Toll-like receptor (TLR) 4 and its downstream signaling molecules were associated with DPN. To assess the diagnostic values of TLR4, TNF-alpha, and IL-6 as biomarkers, here we detected their expressions in peripheral blood from normal controls, type 2 diabetic and DPN subjects. Both TLR4 mRNA and protein expressions increased significantly in DPN compare with both diabetic and control subjects. The protein levels of TNF-alpha and IL-6 were also raised significantly and correlated with TLR4 expression. Receiver operating characteristics (ROC) analysis suggested TLR4 and TNF-alpha had great potential advantages to predict the progression of neuropathy, the risks of DPN were increased in subjects with higher TLR4 (odds ratio: 5.27; 95% CI: 1.02-26.40) and TNF-alpha (odds ratio: 12.67; 95% CI: 2.35-68.22). These findings demonstrated TLR4 and TNF-alpha could be potential sensitive diagnostic biomarkers for DPN in both general population and type 2 diabetic subjects. (C) 2014 Elsevier Ireland Ltd.
