Research Summary
Traumatic Brain Injury (TBI) is a leading cause of morbidity and mortality worldwide, with approximately 1.7 million new cases every year. It is characterized by an initial mechanical injury, leading to secondary physiological responses which result in tissue and cellular degeneration. Current treatments aim to stop or slow the progression of secondary injury in order to promote functional recovery. To date, there are no Food and Drug Administration (FDA) approved pharmacological therapies which adequately promote neuroprotection and/or neuroregeneration and, therefore, functional improvement is minimal, especially in severely injured patients. Given the complexity of the TBI cascade, multi-modal therapies, which combine therapeutic and regenerative effects, may be more effective in promoting functional recovery.

The objective of this project is to develop a therapy which can attenuate neuroinflammation and promote neuroregeneration, thereby leading to enhanced functional recovery. Mesenchymal stromal cells (MSC) are a promising therapy for TBI due to their innate ability to secrete anti-inflammatory and regenerative cytokines and growth factors. Previous work in our lab demonstrated superior immunomodulatory function of encapsulated MSC (eMSC) compared to free MSC, both in vitro and in an in vivo Spinal Cord Injury (SCI) model, where minimal functional recovery was recorded. Thus, we are proposing to improve the therapeutic outcome of eMSC treatment via neurotrophic factor supplementation, which has been shown to be important in promoting axonal elongation and neuronal survival, and which are minimally secreted by MSC. The proposed therapy will entail using eMSC and nanoparticles (NPs) containing neurotrophic factors.
