Research Description
Traumatic brain (TBI) and spinal cord injuries (SCI) render devastating health problems in the United States with an annual cost of approximately 72 billion dollars. This has initiated an enormous focus on the development and discovery of neuroprotective and/or pro-regenerative agents for the treatment of TBI and SCI. Nevertheless, the underlying mechanism(s) of neuronal degeneration and progressive tissue destruction that occurs following such injuries are not fully understood. To begin exploring the cellular and/or molecular mechanisms underlying the pathophysiology of TBI and SCI, it is important to focus on key regulatory steps in the cell death process. Recent evidence indicates that mitochondria, long-known as the “powerhouse” of the cell, play a pivotal role in the cell death cascade. Thus, the main focus of our laboratory is to advance the field of CNS injury research by mapping key events that result in mitochondrial failure and employing this knowledge in developing novel strategies that target these pathways.
