Mechanisms of cAMP signaling that drive spontaneous activity in nociceptors
Project Summary: Chronic pain caused by injury to the peripheral or central nervous system (neuropathic pain) is notoriously resistant to treatment, while the mechanisms that drive and/or maintain chronic pain remain unclear. We have shown that chronic nociceptor hyperexcitability after severe injury is maintained by cAMP signaling through multiple cAMP effectors, including PKA, EPAC and HCN channels. These pathways are enhanced by AKAP-mediated complex formation with AC and show significant cross-talk with Ras/MAPK signaling. Activation of cAMP- and Ras-mediated pathways initiate at the plasma membrane (PM) and are uniquely sensitive to clustering of lipids within the PM. We have also…
