Patent number: 7030100Abstract: Several lines of evidence have shown a role for the nitric oxide (NO)/cyclic guanosine monophosphate (cGMP) signaling pathway in the development of spinal hyperalgesia. However, the roles of effectors for cGMP are not fully understood in the processing of pain in the spinal cord. cGMP-dependent protein kinase (PKG) I? but not PKGI? was localized in the neuronal bodies and processes, and was distributed primarily in the superficial laminae of the spinal cord. Intrathecal administration of an inhibitor of PKGI?, Rp-8-[(4-Chlorophenyl)thio]-cGMPS triethylamine, produces significant antinociception. Moreover, PKGI? protein expression was dramatically increased in the lumbar spinal cord after noxious stimulation. This upregulation of PKGI? expression was completely blocked not only by a neuronal NO synthase inhibitor, and a soluble guanylate cyclase inhibitor, but also by an N-methyl-D-aspartate (NMDA) receptor antagonist, MK-801.Type: GrantFiled: June 28, 2002Date of Patent: April 18, 2006Assignee: Johns Hopkins UniversityInventors: Yuanxiang Tao, Roger A.
