The major focus of my laboratory is to study Traumatic Brain Injury (TBI) andAlzheimer's disease (AD). TBI is a major cause of morbidity and mortality and it affects more than 1.7 million people in the US per year. On the other hand, one in eight older Americans has AD and it is the sixth-leading cause of death in the United States. Both TBI and AD leads to neuronal cell death, inflammation and astrocytic activation those results in major changes in physical and mental health in individuals. Unfortunately, there is no treatment is available to treat both life-threatening disorders. In our laboratory we study the influence of neuro-gasotransmitters like Nitric Oxide (NO), Hydrogen Sulfide (H2S) or Carbon monooxide (CO) on major characteristics of TBI and AD. Our study will provide the framework to design a novel therapeutic strategy to combat against both TBI and AD.
