Neuroinflammation in diabetic peripheral neuropathy and therapeutic implications.

Abstract

Diabetic peripheral neuropathy (DPN) is a serious complication of diabetes mellitus, which is a common cause of disability in individuals with diabetes mellitus. Multiple mechanisms may be involved in the development of DPN. Neuroinflammation is a critical factor contributing to nerve damage during diabetes. Inflammation can induce the development of diabetes mellitus, and long-term hyperglycemia also causes increased oxidative stress and promotes the release of inflammatory cytokines. After reading through the literature, the association of inflammation with the induction of diabetes and DPN was discussed in the review. Inflammation induces nerve damage and nerve conduction impairment. The neuropathic pain in diabetes-induced DPN is also closely associated with the inflammatory response. Given the important roles of inflammation in diabetes-induced DPN, explicit elucidation of neuroinflammation during diabetes mellitus and DPN should hold the potential for developing novel therapeutic strategies for DPN. Experimental studies and limited clinical trials support the value of anti-inflammatory reagents in treating DPN, and the positive outcomes of these investigations warrant further clinical trials.
