One-Line Research Description

Molecular mechanisms of metabolic and neurodegenerative diseases.

The Palladino lab uses Drosophila and human cell lines as model systems to elucidate the cellular and molecular mechanisms of neurodegenerative diseases. Our lab has identified numerous novel neurodegenerative mutants using forward genetics and developed these as unique disease models.  Our research program forces on metabolic disease and the neuromuscular dysfunction they produce with three main goals: 1) discovering and characterizing novel pathways that cause disease, 2) understanding the physiological, cellular, and molecular dysfunction that causes disease in vivo, and 3) using our animal system in pharmacological screens to identify neuroprotective compounds for the treatment of human diseases.  We are currently focusing on elucidating the mechanism by which mutations affecting triose phosphate isomerase (TPI) and mtATP6 function result in glycolytic enzymopthy and mitochondrial encephalaomyopathy, respectively. We are also funded to develop the methodology to use our neurodegenerative mutants in pharmacological screens to identify novel neuroprotectant compounds. To this end we’ve developed a high throughput drug screening platform using a semi-automated optical screening method to identify novel treatments for TPI Deficiency.  We also have the only patient cells including iPS cells of this rare childhood degenerative disease.
