Research Interests
My research is focused on understanding the role and function of lipids and cellular organelles in neurodegeneration and neuroinflammation in traumatic brain injury (TBI) and age-associated neurodegenerative diseases. Our recent study demonstrated that the abundance of ether-phospholipids, an ether bond containing glycerophospholipids, is dysregulated in the mouse cortices after TBI. Ether-phospholipids are major components of the cellular membrane and play an important role in cellular signaling via their structural impact on the formation and function of lipid rafts. Their synthesis is regulated by the concerted functions of peroxisomes and endoplasmic reticulum. Our study demonstrates that ether-phospholipids dysregulation after TBI is at least in part caused by peroxisomal impairment.
Currently, we are exploring the role and function of peroxisomes in the pathophysiology of TBI and ways to develop novel treatment strategies to minimize neurodegeneration and neuroinflammation after TBI by restoring its function in the injured brain.
