Scientific Activity

Our laboratory is interested in understanding the mechanisms by which neuronal cells define and maintain axons different from dendrites and how these structures are progressively affected by degenerative diseases. For these objectives we utilize Drosophila genetics to re-create human neurodegenerative diseases in flies. The expression of mutant human disease genes or targeting homologous genes in Drosophila confers a unique phenotype to the fly and with these fly models we are identifying the proteins and mechanisms involved in neuronal degeneration.
