Abstract
To assess the role of αIG T-type Ca2- channels in neuropathic pain After L5 spinal nerve ligation, we examined behavioral pain susceptibility in mice lacking Cav3.1 (αIG--), the gene encoding the pore-forming units of these channels. Reduced spontaneous pain responses and an increased threshold for paw with drawal in response to mechanical stimulation were observed in these mice. The αIG -- mice also showed attenuated thermal hyperalgesia in response to both low-(IR30) and high-intensity (IR60) infrared stimulation. Our results reveal the importance of neuropathic pain, Ca2- channels in the development of neuropathic pain, and suggest that selective modulation of αIG subtype channels may provide a novel approach to the treatment of allodynia and hyperalgesia.
