My research interests focus on the cellular and molecular mechanisms of chronic pain and genetic approaches for the treatment of pain. Using inflammation and nerve injured rats as chronic pain models I have studied the injury-induced modulation of glutamate and purinergic P2X receptor-mediated responses by second messengers, including Ca2+, nitric oxide, protein kinases and peptides. I also introduced adeno-associated viral vectors which carried the mu-opioid receptor gene (rAAV-MOR) into the dorsal root ganglia of these animals. This manipulation produced a long-lasting up-regulation of MORs in DRG neurons and greatly potentiated the antinociceptive effects of morphine. The information obtained from these studies helps us better understand the mechanisms underlying pain processing and suggests new therapeutic approaches to pain relief.
