Research

Overview

Our research group is interested in understanding the molecular mechanisms that underlie chronic disease like obesity, diabetes, and neurodegeneration. Heat shock proteins (HSPs) are a highly conserved family of proteins best identified for their role as molecular chaperones. They play a critical role in maintaining cellular function via regulation of protein folding and degradation, and changes in their expression profile and cellular location have been linked to numerous disease states. Our laboratory has demonstrated the ability of HSPs to mediate glucose homeostasis and insulin action in muscle, liver and adipose tissue. Our more recent work examines the role of HSPs in regulating proteostasis and improving neuronal health in Alzheimer’s Disease models. We are examining the possibility that exercise and heat therapy (hot water immersion in a hot tub) may benefit the brain by facilitating the delivery of molecular mediators within extracellular vesicles (EVs; exosomes and microvesicles). EVs are bilayer-phospholipid enclosed vesicles released by cells that can carry cellular proteins and microRNA within bodily fluids, including blood and cerebral spinal fluid. We hypothesize that EVs provide a novel intercellular signaling mechanism to deliver HSPs and associated cargo from skeletal muscle to brain neuronal cells that has not been thoroughly evaluated in the context of the etiology of Alzheimer’s Disease. Finally, we are interested in translating our mechanistic research findings from animal and cell models into novel therapeutic approaches for prevention of metabolic and neurodegenerative disease via heat therapy.
