Neuropathic pain involves neuroinflammation and upregulation of glycolysis in the central nervous system. Unfortunately, few effective treatments are available for managing this type of pain. The overactivation of lactate dehydrogenase A (LDHA), an essential enzyme in glycolysis, can cause neuroinflammation and nociception. This study investigated the spinal role of LDHA in neuropathic pain. ⋯ In conclusion, LDHA may be a potential therapeutic target for treating neuropathic pain by regulating neuroinflammation and angiogenesis.

Clinical study of a micro-implantable pulse generator for the treatment of peripheral neuropathic pain: 12-month results from the COMFORT-randomized controlled trial.
There is paucity of data from randomized controlled trials supporting the use of peripheral nerve stimulation, a well-established therapy for the treatment of chronic pain. This study was undertaken, in part, to provide randomized controlled trial data in support of patient access to appropriate peripheral nerve stimulation therapy. The COMFORT study is the first large, postmarket, multicenter randomized controlled trials investigating the use of a Food and Drug Administration-cleared micro-implantable pulse generator (IPG) for treating chronic pain via peripheral nerve stimulation therapy. ⋯ These 12-month results are consistent with previously reported 6-month outcomes from this study, showing durability of peripheral nerve stimulation treatment with the micro-IPG system; subjects realized sustained large reduction in pain and improvement in patient-reported outcomes following treatment with this micro-IPG system.

Neuropathic pain (NP) is a widespread public health problem that existing therapeutic treatments cannot manage adequately; therefore, novel treatment strategies are urgently required. G-protein-coupled receptors are important for intracellular signal transduction, and widely participate in physiological and pathological processes, including pain perception. ⋯ Here we reviewed the advantages of Group I mGluRs negative allosteric modulators (NAMs) over orthosteric site antagonists based on allosteric modulation mechanism, and the challenges and opportunities of Group I mGluRs NAMs in NP treatment. This article aims to elucidate the advantages and future development potential of Group I mGluRs NAMs in the treatment of NP.

KDM4A facilitates neuropathic pain and microglial M1 polarization by regulating BDNF in a rat model of brachial plexus avulsion.
Many patients with brachial plexus avulsion (BPA) suffer from neuropathic pain, but the mechanism remains elusive. Modifications of histones, the proteins responsible for organizing DNA, may play an important role in neuropathic pain. Lysine demethylase 4A (KDM4A), an essential component of histone demethylase, can modify the function of chromatin and thus regulate the vital gene expressions. However, the mechanism by which KDM4A regulates neuropathic pain following BPA remains unclear. ⋯ Current findings suggest that the upregulation of KDM4A increases BDNF expression in the spinal cord in rats after BPA, contributing to microgliosis, neuroinflammation, and neuropathic pain.
