Nian Gong, John Park, Z David Luo
Voltage gated calcium channels (VGCCs) play important roles in physiological functions including modulations of neurotransmitter release, neuronal network activities, intracellular signaling pathways, and gene expression. Some pathological conditions, including nerve injuries, can cause dysregulation of VGCCs and their subunits. This in turn can lead to functional maladaption of VGCCs and their subunits, which can contribute to development of disorders such as pain sensations. This review summarized recent findings related to maladaptive changes of dysregulated VGCC alpha-2-delta-1 subunit (Cav α2 δ1 ) with a focus on exploration of mechanisms underlying contribution of Cav α2 δ1 to pain signal transduction...

Spinal cord stimulation can be a valuable treatment option in the management of neuropathic pain in select pediatric patients. We present a unique case of a 16-year-old girl with Klippel-Trenaunay-Weber syndrome and scoliosis who required the placement of a spinal cord stimulator (SCS) for severe sciatic nerve neuropathic pain after a right above-knee amputation. Several attempts at lead placement were required before successful pain coverage was achieved because of late recognition of significant vertebral body rotation...

Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system associated with progressive neuronal loss and axonal degeneration. Neuronal lesions and dysfunction lead often to neuropathic pain, the most prevalent and difficult to treat pain syndrome observed in MS patients. Despite its widespread occurrence, the underlying neural mechanisms for MS pain are not fully understood. For a better clarification of the pathophysiology of MS-associated pain, we investigated the role of HuR, an RNA-binding protein that positively regulates the stability of many target mRNAs, including several cytokines...

No satisfactory effective therapy is still available to treat trauma- or disease-induced neuropathic pain, and current available treatment options have several side effects. Pulsed magnetic field (PMF) treatments are receiving growing interest as a therapeutic approach for several neuronal diseases. Although the exact mechanism of action of PMF treatments is unknown, reported findings represent a promising alternative therapeutic choice for the management of neuropathic pain. PMF treatments can supply new strategies for the therapy of life-threatening neuropathic pain due to its antihyperglycemic, anti-inflammatory, antihyperalgesic, antiallodynic, and neuroimmunomodulatory actions...

BACKGROUND: The molecular underpinnings of spinal cord injury (SCI) associated with neuropathic pain (NP) are unknown. Recent studies have demonstrated that matrix metalloproteinases (MMPs) such as MMP2 play a critical role in inducing NP following SCI. Promoter methylation of MMPs is known to suppress their transcription and reduce NP. In this context, it has been shown in rodents that folic acid (FA), an FDA approved dietary supplement and key methyl donor in the central nervous system (CNS), increases axonal regeneration and repair of injured CNS in part via methylation...

Chronic pain is a major public health issue with an incidence of 20-25% worldwide that can take different forms like neuropathic, cancer-related or inflammatory pain. Chronic pain often limits patients in their daily activities leading to despair. Thus, the goal of treatments is to relieve pain sufficiently to enable patients to go back to a normal life. Unfortunately, few patients with chronic pain obtain complete relief from the analgesics that are currently available. It is thus of prime importance to get a better understanding of chronic pain mechanisms to design new therapeutic strategies and pain-killers...

Neuropathic pain is a complex, chronic pain state accompanied by tissue injury and nerve damage. This important health issue constitutes a challenge for the modern medicine worldwide. The management of neuropathic pain remains a major clinical challenge, pertaining to an inadequate understanding of pathophysiological mechanisms of neuropathic pain. Various classes of drugs have been reported effective for the management of neuropathic pain viz. opiates, tricyclic antidepressants, and antiepileptic agents. However, association of adverse effects with these drugs hinders their confident prescription in people with neuropathic pain...

BACKGROUND: Terminal neuromas resulting from severe nerve injuries and traumatic or surgical limb amputations can become a source of pain, and significantly impair patients' quality of life. Recently, the number of patients with peripheral nerve injuries increased due to modern war conflicts, natural disasters, and traffic accidents. This study investigated the efficacy of the epineural sheath jacket (ESJ) as a novel technique for neuroma prevention in the rat sciatic nerve model. METHODS: A 20-mm segment of the right sciatic nerve was excised in 18 Lewis rats, and the animals were divided into 3 experimental groups (n = 6/group): group I-control, nerve stump without protection; group II-muscle burying group, nerve stump buried in the muscle; group III-ESJ group, nerve stump protected by ESJ...

Bone cancer pain (BCP) is a common complication with inadequate management in patients suffering from advanced cancer. Histone deacetylase inhibitors showed significant analgesic effect in multiple inflammatory and neuropathic pain models, but their effect in bone cancer pain has never been explored. In this study, we utilized a BCP rat model with intra-tibial inoculation of Walker 256 mammary gland carcinoma cells, which developed progressive mechanical hypersensitivity but not thermal hypersensitivity. Intrathecal application of trichostatin A (TSA), a classic pan-HDAC inhibitor, ameliorated tactile hypersensitivity and enhanced the analgesic effect of morphine in BCP rats...

Cell transplantation offers an attractive alternative to pharmacotherapy for the management of a host of clinical conditions. Most importantly, the transplanted cells provide a continuous, local delivery of therapeutic compounds, which avoids many of the adverse side effects associated with systemically administered drugs. Here, we describe the broad therapeutic utility of transplanting precursors of cortical inhibitory interneurons derived from the embryonic medial ganglionic eminence (MGE), in a variety of chronic pain and itch models in the mouse...

Spinal cord injury (SCI) causes chronic pain in 65% of individuals. Unfortunately, current pain management is inadequate for many SCI patients. Rodent models could help identify how SCI pain develops, explore new treatment strategies, and reveal whether acute post-SCI morphine worsens chronic pain. However, few studies explore or compare SCI-elicited neuropathic pain in rats. Here, we sought to determine how different clinically relevant contusion SCIs in male and female rats affect neuropathic pain, and whether acute morphine worsens later chronic SCI pain...
