WebMar 22, 2024 · Upon development of DPN after 4 weeks, mice were investigated for mechanical allodynia (von Frey filament pressure test) and thermal hyperalgesia (tail immersion test). Ondansetron (1.0 mg/kg i.p.), naloxone (3.0 mg/kg i.p.) and yohimbine (2.0 mg/kg i.p.) were used to elucidate the possible mechanism involved. WebSensitization of cutaneous C-fiber nociceptors contributes to secondary mechanical allodynia. It is well established that central sensitization—i.e., a strengthening of synaptic transmission in pain processing circuits in the spinal cord—contributes to the development of secondary mechanical hypersensitivity 40, 41.
WebConclusions: The TRPA1 channel mediates mechanical allodynia and thermal hyperalgesia in a rat BCP model. Introduction Since numerous advanced medicines and technologies have been explored and used for cancer treatment, patients with tumors exhibit longer survival times ( 1, 2 ). WebApr 5, 2016 · In contrast, heat and mechanical pain are unchanged, and results show that, in striking contrast to the redundant mechanisms sensitizing other modalities after an insult, cold allodynia is mediated exclusively by a single molecular pathway, suggesting that artemin–GFRα3 signaling can be targeted to selectively treat cold pain.
