Contributions of the Immune Response After Nerve Injury to NMJ Reinnervation

Principal Investigator
Alison Snyder-Warwick MD


Washington University in St.Louis

Funding Mechanism
ASPN/PSF Research Grant

Focus Area
Peripheral Nerve

Peripheral nerve injuries are devastating, resulting in functional loss, deformity, and paralysis. Recovery following nerve injury is often poor. A more comprehensive strategy for management of patients with nerve injury should include knowledge related to nerve regeneration, the target muscle, and the neuromuscular junction (NMJ), which interfaces these structures.

At the NMJ, supporting glial cells called terminal Schwann cells (tSCs) assist with muscle reinnervation and nerve sprouting following injury. In response to injury, tSCs extend long cytoplasmic processes in an attempt to optimize NMJ reinnervation. Recent studies implicate a role for macrophages and angiogenesis in Schwann cell guided axonal regeneration at the site of nerve injury. In this proposal, we utilize multiple mouse models to determine the contributions of macrophages and angiogenesis to tSC guided NMJ reinnervation after nerve injury. The data generated from this proposal will fuel an innovative area of tSC and immunomodulatory investigation that may provide novel translational applications for enhanced management of patients with motor nerve injuries.

Dr. Alison Snyder-Warwick is an Associate Professor of Surgery in the Division of Plastic and Reconstructive Surgery and Director of the Facial Nerve Institute at Washington University in St. Louis. Dr. Snyder-Warwick completed medical school, a research fellowship in Developmental Biology, and surgical residency training all at Wash U. She then travelled to Toronto, Canada for specialized training in pediatric plastic surgery and pediatric microsurgery at the Hospital for Sick Children. Dr. Snyder-Warwick’s main clinical focus includes pediatric plastic surgery and reconstruction for facial nerve disorders, treatment of facial clefts, reconstruction of brachial plexus birth injuries, gender-affirming surgery, and pediatric and adult microsurgical procedures. Her clinical interests have led to pioneering basic science research investigations involving the terminal Schwann cell, a unique glial cell present at the nerve-muscle interface. Dr. Snyder-Warwick is passionate about helping children and adults with facial paralysis, nerve-related injuries, and facial anomalies and is committed to studying novel techniques of optimizing care for people affected by peripheral nerve pathology and facial differences.
