Plasticity and Repair of Neural Connections between Spinal cord and Muscle


  • Sensory nerve regeneration
  • Neuromuscular junctions
  • Spinal root injuries
  • Neuromuscular disorders

My lab wants to elucidate the mechanisms that govern maintenance and regeneration of synaptic connections in the spinal cord and muscle, particularly those associated with glial cells. I discovered earlier, with Wes Thompson, that Schwann cells play pivotal roles in restoring synaptic connections in muscles, i.e., neuromuscular junctions (NMJs). I have then extended the discovery by identifying glia-associated factors that promote formation and maintenance of NMJs (e.g., mAChRs and CAMs), by investigating factors that disturb stability of mature NMJs (e.g., spinal cord injury, paralysis), and by studying roles of Schwann cells and other glia in sensory nerve regeneration (i.e., restoration of sensory synaptic connections in the spinal cord). My lab was the first to demonstrate that particular muscles paralyzed by spinal cord injury fail to maintain NMJs and therefore lose neural connections with the spinal cord. We also showed that muscarinic signaling is a novel receptor system essential for stable maintenance of NMJs. This latter finding lays the foundation for a new line of investigation of how spinal cord-muscle connections are maintained in muscles in an activity dependent manner. More recently, we have begun to utilize stem cells to restore spinal cord-muscle connections. Technically, my lab has pioneered in applying time-lapse in vivo imaging and fluorescent transgenic mice to study spinal root regeneration, asking why sensory axons fail to regenerate into spinal cord, and how to promote regeneration and synaptic connections with the spinal cord. We hope that our work, which uses various state-of-the-art molecular and cellular techniques, will lead to novel therapeutic strategies to promote repair of spinal cord-muscle connections in patients with neuromuscular, spinal cord or spinal root injury.
