Traumatic Brain Injury
   Research Center


Our Research Team

Investigators in the Division of Neuropathology have a 25 year-history of studying neural injury and repair, including characterization of the responses of central and peripheral neurons to axonal injury; characterization of mechanisms of apoptosis and neuronal cell death; demonstration of the roles of neurotrophic peptides as therapeutics in models of neural injury; and pioneering the use of stem cells to support or replace dying neurons and to restore simple neural circuits. Furthermore, our investigators have pioneered genetic rodent models of neurodegenerative diseases including AD and ALS and have clarified key molecular steps leading to pathogenic protein aggregation in these disorders; these technologies and discoveries will play key roles in investigations of neurodegenerative mechanisms initiated by TBI.
