Mechanisms of neurodegeneration in human diseases using Drosophila genetics.

Description of Research

In our laboratory we have created fruit fly models of the most common human neurodegenerative diseases, including Amyotrophic Lateral Sclerosis (ALS), Alzheimer’s disease and (AD) and Spastic Paraplegia. By modulating the expression of conserved proteins, we have recreated the main characteristics of the human disorders in flies. We are now utilizing the genetic tools developed in Drosophila to identify genes and metabolic pathways controlling the onset and progression of ALS. Similar strategy was taken to study AD and Spastic Paraplegia. We hope that these studies will provide insight into neuronal homeostasis and lead to new treatments.
