Nociceptive receptors are expressed differently in trigeminal nociception after lingual nerve injury and unilateral external carotid artery occlusion in rats. Arch Oral Biol 2021; 126:105128. [PMID: 33895544 DOI: 10.1016/j.archoralbio.2021.105128] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2020] [Revised: 04/06/2021] [Accepted: 04/14/2021] [Indexed: 10/21/2022]
Abstract
OBJECTIVES To investigate the different changes in nociceptive activity between two animal models of trigeminal neuropathic pain: unilateral external carotid artery ischemic reperfusion and lingual nerve crush in rats. DESIGN In this study, changes in nociceptive activity were investigated in unilateral external carotid artery ischemic reperfusion and lingual nerve crush models of trigeminal neuropathic pain in rats. Field excitatory postsynaptic potentials (fEPSPs) evoked by capsaicin application on the tongue of rats were recorded in the trigeminal nucleus caudalis. In addition, immunohistochemistry was performed in the trigeminal ganglia and trigeminal nucleus caudalis. RESULTS The fEPSP in unilateral external carotid artery ischemic reperfusion and lingual nerve crush rats was irregular relative to that in sham rats. In particular, the fEPSP spike in lingual nerve crush rats had a higher amplitude and shorter duration than that in sham rats. Unilateral external carotid artery ischemic reperfusion and lingual nerve crush also increased c-fos expression in the trigeminal nucleus caudalis. Upregulation of transient receptor potential vanilloid 1 in trigeminal ganglion was observed in unilateral external carotid artery ischemic reperfusion and lingual nerve crush rats, whereas upregulation of purinergic receptor subtype 3 in trigeminal ganglion was observed only in lingual nerve crush rats. CONCLUSIONS Although unilateral external carotid artery ischemic reperfusion and lingual nerve crush similarly increased nociceptive activity at the trigeminal nucleus caudalis, the fEPSPs and expression of nociceptive peripheral afferent neurons were different. Therefore, direct and indirect nerve injuries apparently induced the same nociceptive activity by different signaling responses dependent on nociceptive receptors.

Ameliorative effect of gallic acid in paclitaxel-induced neuropathic pain in mice. Toxicol Rep 2019; 6:505-513. [PMID: 31211096 PMCID: PMC6562321 DOI: 10.1016/j.toxrep.2019.06.001] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2018] [Revised: 05/28/2019] [Accepted: 06/06/2019] [Indexed: 12/20/2022] Open
Abstract
Gallic acid (GA) is a natural phenolic type of neuroprotective compound. GA possesses anti-nociceptive action against paclitaxel-induced neurotoxicity. GA inhibits THF-α mediated neuropathic pain sensation.
The present study has been investigated the role of gallic acid (GA) in paclitaxel-induced neuropathic pain. The neuropathic pain was developed with paclitaxel (PT: 2 mg/kg, i.p.) administration in mice. GA (20 and 40 mg/kg) and pregabalin (PreG: 5 mg/kg) were administered intravenously for 10 consecutive days. The neuralgic sensations were investigated by assessing various pain tests like acetone drop, pinprick, plantar, tail flick, and tail pinch test. Mice pain behaviors were evaluated on 0, 4th, 8th, 12th and 16th days. The levels of sciatic nerve thiobarbituric acid reactive substances (TBARS), reduced glutathione (GSH), superoxide anion, calcium, myeloperoxidase (MPO), and TNF-α were estimated. Treatment of GA and PreG attenuate PT induced thermal &mechanical hyperalgesia and allodynia symptoms along with the reduction of TBARS, total calcium, TNF-α, superoxide anion, and MPO activity levels; and decreased GSH level. Therefore, it has been concluded that GA has potential neuroprotective actions against PT induced neuropathic pain due to it's anti-oxidant, anti-inflammation and regulation of intracellular calcium ion concentration.

Resveratrol alleviates nuclear factor-κB-mediated neuroinflammation in vasculitic peripheral neuropathy induced by ischaemia-reperfusion via suppressing endoplasmic reticulum stress. Clin Exp Pharmacol Physiol 2019; 46:770-779. [PMID: 31090224 DOI: 10.1111/1440-1681.13105] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2019] [Revised: 04/28/2019] [Accepted: 05/09/2019] [Indexed: 12/29/2022]
Abstract
Vasculitic peripheral neuropathy (VPN) arises from an inflammatory obstruction in the blood vessels supplying peripheral nerves and subsequent ischaemic insults, which exhibits the clinical features of neuropathic pain and impaired peripheral nerve function. VPN induced by ischaemia-reperfusion (IR) has been reported to involve nuclear factor-κB (NF-κB)-mediated neuroinflammation. Recent studies have suggested that endoplasmic reticulum (ER) stress has been implicated in the development of peripheral neuropathies. Resveratrol possesses a potent anti-inflammatory capacity. We hypothesized that resveratrol may exert a protective effect against VPN through modulating the interrelated ER stress and NF-κB pathways. Male Sprague-Dawley rats were allocated into five groups: sham, sham + resveratrol 40 mg/kg (R40), IR, IR + R20 and IR + R40. VPN was induced by occluding the right femoral artery for 4 hours followed by reperfusion. Our data have shown that VPN induced by IR led to hind paw mechanical allodynia, heat hyperalgaesia, and impaired motor nerve conduction velocity (MNCV). With resveratrol intervention, the behavioural parameters were improved in a dose-dependent manner and the MNCV levels were increased as well. The molecular data revealed that VPN induced by IR significantly increased the expression of NF-κB as well as the ER stress sensor proteins, protein kinase RNA-like endoplasmic reticulum kinase, inositol-requiring enzyme 1 and activating transcription factor 6 in the sciatic nerves. More importantly, resveratrol significantly attenuated the expression of NF-κB and the ER stress sensor proteins after IR. In conclusion, resveratrol alleviates VPN induced by IR. The mechanisms may involve modulating NF-κB-mediated neuroinflammation via suppressing ER stress.

Abstract
Animal disease models contribute to a better understanding of the pathogenic mechanisms of human and animal diseases and help develop treatments for them. Ligation of the rat iliac arteries
is performed to reproduce erectile dysfunction and peripheral arterial disease. Although knowledge of the ramification of branches from the rat iliac artery is important to perform such
surgery, descriptions in previous studies are insufficient. Therefore, 17 male and 18 female Wistar rats were observed to elucidate the detailed ramification patterns of branches from the
iliac arteries with the latex injection method. The iliac arteries branched off the umbilical, cranial gluteal, lateral and medial circumflex femoral, external pudendal, and caudal
epigastric arteries, and the common trunk of the caudal gluteal and internal pudendal arteries. The branching pattern of the umbilical, cranial and caudal gluteal, and internal pudendal
arteries varied greatly and was categorized as Types 1 to 3 based on the number of branching levels along the proximodistal axis of the iliac arteries. Based on the same criteria, the
ramification patterns of the lateral and medial circumflex femoral arteries were also divided into Groups 1 and 2. The external pudendal and caudal epigastric arteries originated from the
external iliac artery mainly as a common trunk or less frequently as independent arteries in this order. The detailed branching patterns of the rat iliac arteries elucidated in the present
study are beneficial for the refinement of surgical procedures.

Vasculitic peripheral neuropathy induced by ischemia-reperfusion in the rat femoral artery involves activation of proinflammatory signaling pathway in the sciatic nerve. Neurosci Lett 2017; 656:77-82. [PMID: 28732764 DOI: 10.1016/j.neulet.2017.07.031] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2017] [Revised: 06/27/2017] [Accepted: 07/17/2017] [Indexed: 11/26/2022]
Abstract
Ischemia-reperfusion (IR) in the rat femoral artery has been proposed as an experimental model of vasculitic peripheral neuropathy (VPN) which presents neuropathic pain and peripheral nerve injury patterns observed clinically. This study investigates the involvement of the proinflammatory signaling pathway underlying the peripheral mechanisms of VPN. Male Sprague-Dawley rats were allocated to receive either a sham operation or IR. IR was induced by occluding the right femoral artery for 4h followed by reperfusion periods from 0 to 72h. The behavioral parameters were assessed at baseline as well as at days 1, 2 and 3 after reperfusion. The time-course analyses of proinflammatory mediators in the sciatic nerves were also performed on rats of the sham group or IR groups with reperfusion periods of 0, 2, 4, 24 and 72h, respectively. The behavioral data confirmed that this VPN model induced hindpaw mechano-allodynia and heat hyperalgesia as well as impaired hindpaw grip strength. The molecular data revealed that IR in the femoral artery activated the expression of nuclear factor-κB (NF-κB) in the sciatic nerve indicating a neuroinflammatory response. Moreover, IR in the femoral artery increased the expression of proinflammatory cytokines TNF-α and IL-1β in the sciatic nerve. This study elucidated the novel time-course expression profiles of NF-κB and proinflammatory cytokines in VPN induced by IR which may be involved in the development of neuropathic pain. Since NF-κB is a key element during neuroinflammation, strategies targeting the NF-κB signaling pathway may provide therapeutic potential against VPN induced by IR.
