Biography

Tanusree Sen, PhD, joined the University of Pittsburgh Department of Neurological Surgery in March of 2017 as a research assistant professor.

As part of her PhD training, she developed expertise in the area of oxidative stress-mediated cellular dysfunctions and brain aging. In 2007 after her graduation, she joined the research group of David Sidransky, MD, at Johns Hopkins University’s Division of Head and Neck Cancer. In Dr. Sidransky lab, Dr. Sen worked on multiple projects unraveling the molecular pathways and mechanism involving in different cancer including cigarette smoking-induced bladder cancer. Her work studied the mechanism involved p53 isoform, p63 for cell death and chemoresistance and she discovered novel mechanisms which were shown to play a key role in cell death associated with several different cancer. In a separate project of age-related macular degeneration, she discovered the key role of lens structural protein CRYBA1 in anoikis and autophagy process in mouse retinal astrocytes and retinal pigmented epithelial cells.

In 2012, Dr. Sen joined Augusta University as a postdoctoral fellow and extended her expertise of cellular-molecular biology in the field of immunology, autoimmunity and traumatic brain injury and discovered molecular mechanism regulating neuronal death and memory function after traumatic brain injury.

In 2015, Dr. Sen started working as a research assistant professor at the University of Georgia and worked on the mechanism of diet-induced vagal nerve injury specifically in the context of the gut-microbiota-inflammation-brain axis. At this time she discovered how different diet may contribute to gut microbial dysbiosis, inflammation and subsequently damage to the vagal nerve. Dr. Sen has published 33 papers in refereed journals with total citations have exceeded 2500.

Research Activities

The activation of an oncogenic transcription factor in the peripheral tissues have been well studied; however, the influence of these factors on the brain function and neurological disorders have not been studied to that extent. Dr. Sen would like to elucidate the function of these transcription factors on several pathological outcomes of TBI, which is characterized by an induction of cell death, edema, inflammation and cognitive dysfunction.

Dr. Sen’s preliminary data indicate that a transcription factor, p63, which is a family member of the tumor suppressor, contributes to the pathological outcomes of TBI in several layers. In addition, Dr. Sen is in a process to understand the cellular and molecular mechanism of how p63 regulates the oxidative/ER stress, alteration in mitochondrial structure and function and cognitive impairment.

In addition, Dr. Sen have been working to understand whether the immune cells from the peripheral tissues contributes to brain immunological response following TBI. In general, the peripheral immune cells cannot enter unto the brain because they can not pass through the blood-brain barrier. However, in TBI patients the existence of peripheral immune cells has been identified, but their role in the pathogenicity has not been studied well.  The major objective of this project is to understand how these cells enter into the brain and how/whether they function independently or in association with the residential immune cells in the brain.

In the last few years, Dr. Sen has studied the functional aspects of transcription factors such CREB and HIF1 and their contribution to release of a neurotransmitter, such as BDNF in the brain and neurogenesis and angiogenesis processes following TBI. Dr. Sen would like to combine her experience of studying oncogenic transcription factors and function of immunological cells with the expertise of studying several aspects of TBI-pathology to accomplish the goals and objectives of current projects.
