Description of Graduate Research:
Neuropathic pain is a significant public health problem, which comprises a large percentage of visits to pain clinics and has a significant monetary impact on healthcare costs. Following injury there are endogenous nociceptive signals sent from sensory neurons to dorsal horn neurons. Understanding the mechanisms that allow for prolonged pro-nociceptive signaling in the dorsal horn is vital for understanding the transition from acute to chronic pain. The novel neuropeptide precursor VGF has been implicated in a wide variety of neural processes, including learning, memory, depression, and chronic pain. We have shown that the VGF-derived peptide TLQP-21 contributes to both the development and maintenance of hypersensitivity after peripheral nerve injury and inflammation. The effects of TLQP-21 are mediated by the complement 3a receptor C3aR1, and we have demonstrated that hyperalgesia evoked by intrathecally administered TLQP-21 depends on C3aR1 activation. Upregulation of C3aR1 in microglia has been found following CNS injury, and my results indicate that TLQP-21 evokes calcium transients in cultured primary microglia. Additionally, we have found that TLQP-21/C3aR1 signaling is increased following peripheral nerve injury specifically in dorsal horn microglia. The goal of my project is to investigate TLQP-21/C3aR1 mediated microglial signaling after injury and to examine the potential contribution of microglia to neuropathic pain.
