BACKGROUND Gabapentin is an anticonvulsant and adjuvant analgesic. It is effective in several pain studies. Neuropathic pain is the most difficult type of pain to treat. In this study, we examined if intrathecal gabapentin could prevent nerve injury-induced pain. METHODS Under isoflurane anaesthesia, male Sprague-Dawley rats (200-250 g) underwent right L5/6 spinal nerve ligation and placement...
OBJECTIVE Peripheral nerve injury elicits an aversive state of spontaneous neuropathic pain, and up to now, the modulation of this concomitant aversive state remains a major therapeutic challenge. NMDA receptor subunits NR2B in the rACC are critically involved in the processing of this aversive state and then a strategy targeted at the NR2B subunit might be promising for modulation of the avers...
The N-methyl-D-aspartate (NMDA) receptor has been implicated in a variety of systems that undergo plastic changes in the central nervous system. We used electron microscopic immunocytochemistry with an antibody directed against an alternatively spliced exon near the C terminus of NMDAR1, the essential functional subunit of the NMDA receptor, to study the distribution of the NMDA receptor in the...
Neuropathic pain remains intractable and the development of new therapeutic strategies are urgently required. Accumulating evidence indicates that overproduction of oxidative stress is a key event in the pathogenesis of neuropathic pain. However, repeated intra-peritoneal or intrathecal injections of antioxidants are unsuitable for continuous use in therapy. Here we show a novel therapeutic met...
Background & Aims : Axonal transport is a vital process in nervous system that protects axons and nerve terminals through supplying proteins, lipids and mitochondria and clearing folded proteins to avoid toxicity. Recently it is reported that impairment of motor proteins involved in axonal transport-like dynactin is a common factor in several neurodegenerative disorders such as Amyotrophic ...
Neuropathic pain is often "spontaneous" or "stimulus-independent." Such pain may result from spontaneous discharge in primary afferent nociceptors in injured peripheral nerves. However, whether axotomized primary afferent nociceptors give rise to pain is unclear. The rostral anterior cingulate cortex (rACC) mediates the negative affective component of inflammatory pain. Whether the rACC integra...
Abnormal cold sensitivity is a common feature of a range of neuropathies. In the murine somatosensory system, multiple aspects of cold sensitivity are dependent on TRPM8, both short term and in response to peripheral nerve injury. The specialized nature of cold-sensitive afferents and the restricted expression of TRPM8 render it an attractive target for the treatment of cold hypersensitivity. T...
