## Abstract

Traumatic brain injury (TBI) is a major cause of long-term disability in active-duty personnel and
Veterans. Improvements in body armor have greatly reduced injuries to the vital organs and advances in
emergency surgery have saved countless lives. Unfortunately, neurological dysfunctions following TBI
represent one area where relatively little progress was made. TBI ranging from mild (concussions) to severe
are produced in large numbers on the modern battlefield, especially as result of exposure to improvised
explosive devices (IED) and paradoxically, improvements in other areas of emergency care has greatly
increased the numbers of warfighters that live to experience the long-term negative effects of TBI. In spite of
significant research efforts, no treatments for TBI have been shown to be to be clinically effective. At present,
most acute post-TBI care is limited to supportive interventions and avoidance of repeat injuries with the hope
that unaided physiological repair mechanisms will, over time improve the neurological dysfunctions.
Unfortunately, large numbers of Veterans that have suffered TBI are left to cope with chronic neurological
deficits including motor and cognitive impairments. It is imperative to propose and validate therapeutic
strategies that would positively impact this large group of patients of particular importance to the VA system.
Research has shown that TBI initiates multiple cascades of secondary molecular changes that cause delayed
and progressive tissue damage, which lead to neurological dysfunction. Both intrinsic neuronal cell death
mechanisms and secondary neurotoxicity following neuroinflammation are thought to contribute to the neuronal
loss following brain trauma. Although much of the research focus has been directed at elucidating relatively
early cellular and molecular events, experimental evidence suggests that the pathobiological processes
initiated by TBI may continue for as long as a year or more after trauma- contributing to progressive
neurodegeneration and chronic neurological deficits. Recent evidence suggests that persistent
neuroinflammation following central nervous system (CNS) trauma lasts for months and even years, and may
be responsible for chronic neurodegeneration and chronic neurological dysfunction. The goal of the proposed
research is to demonstrate that the chronic secondary injury processes initiated by TBI and the secondary
neurological deficits are not irreversible and represent a prime target for therapeutic intervention. This proposal
is designed to test the hypothesis that delayed exercise and/or pharmacologic approaches targeting key
secondary injury mechanisms can effectively reduce neuronal loss and neuroinflammation, and promote
neuroplasticity responses resulting in attenuation of neurological dysfunction following TBI. The proposed
studies designed to test our hypothesis will use a well-established animal experimental model of TBI,
controlled cortical impact (CCI) in mice. This ...
