Studies on Traumatic Brain Injury

My laboratory is interested in the pathophysiology, diagnosis and treatment of neurodegenerative diseases, in particular, traumatic brain injury (TBI).

TBI now is recognized as a major public health problem, yet there are no treatments for TBI. Two major reasons why drugs have failed clinical trials is that TBI produces a heterogeneous injury and mild TBI is the most common head injury and patients with mild TBI often do not seek medical help for days after injury. An effective drug to treat TBI needs high potency when dosed days after injury. The drug combination, minocycline plus N-acetylcysteine repairs both injury to white matter when first dosed at 12 hours post-injury and limits gray matter injury when first dosed at 72 hours. The drugs modulate inflammation, restores memory and limits neuronal loss. Both drugs have FDA-approval for uses other than TBI suggesting that the combination is both safe as well as effective.

The scale bar corresponds to 100 μm. B, Representative images of corpus callosum stained with myelin-specific stain luxol fast blue. Myelin loss in TBI saline-treated brains was partially restored by treatment with MINO plus NAC.
