The Johnson lab uses invertebrate model organisms (fruit flies and worms) to better understand aging and age-related diseases. A common feature of many degenerative diseases is the progressive accumulation of protein aggregates. Autophagy-lysosome mediated degradation is the major pathway that clears aggregates from the cytoplasm and autophagy defects are associated with many degenerative diseases. We use a combination of genetic, biochemical and microscopy methods to study the autophagy-lysosome system in both healthy and disease contexts. Additionally, we are exploring natural mechanisms that enhance proteostasis as a potential therapeutic approach to combat neurodegenerative diseases.
