Shermali Gunawardena's research focuses on how genetic mutations in the fruit fly can lead to “traffic jams” in the brain's transport system. Some scientists think such blockages may precede formation of plaques in certain neurological disorders. Gunawardena's work aims to inform new avenues for treating or preventing diseases such as Alzheimer’s. The Gunawardena Lab is now featured in a slideshow by UB Seen.
Axonal transport and neurodegenerative disease
Within axons vital cargoes must be transported over great distances along microtubule tracks to maintain cell viability. In neuronal cells, many proteins function in sending and receiving messages, cell repair, and cell protection. My interest is to elucidate if degeneration of neurons in two neurodegenerative diseases (Alzheimer’s disease or Huntington’s/other polyQ diseases), is related to a defect in this long distance transport system and what mechanisms facilitate the normal transport of APP and huntingtin.
