Shetty, Ashok individual record
Professor and Associate Director

Dr. Ashok K. Shetty's laboratory is interested in developing clinically applicable strategies efficacious for enhancing brain function after injury, disease, or aging. The central areas of investigation are focused on:

o Mechanisms by which intranasally administered stem cell-derived extracellular vesicles (EVs) promote neuroprotection, neuroregeneration, neural plasticity, and alleviate neuroinflammation. The sources of EVs include human bone marrow mesenchymal stem cells (hMSCs), and human induced pluripotent stem cell-derived neural stem cells (hiPSC-NSCs), astrocytes, and microglia. The model systems include traumatic brain injury (TBI), closed head injury (CHI), Aging, Alzheimer's disease (AD) and temporal lobe epilepsy (TLE).

o Mechanisms by which transplanted human neural stem cells or human GABA-ergic precursor cells derived from hiPSCs promote brain repair, and alleviate spontaneous seizures, and cognitive and mood impairments in prototypes of SE, TLE, and TBI.

o Elucidating mechanisms of brain dysfunction and chronic neuroinflammation in prototypes of Gulf War Illness. Developing therapeutic strategies to alleviate neuroinflammation, systemic inflammation, and cognitive and mood impairments in models of GWI.

o Developing clinically feasible strategies for improving brain function in aging and AD models via stimulation of endogenous neural stem cells using drugs and biologics.

Dr. Shetty has received continuous extramural research funding as PI for >25 years from sources such as the NIH, DOD, Dept of Veterans Affairs (VA), and industry. These include five R01 grant awards and an R21 grant award from the NIH; seven CDMRP grant awards from the DOD; five Merit Grant awards and two Research Career Scientist Awards from the VA; and two industry grants.
