Neurodegenerative diseases: Deadly droplets

A new study by LMU researchers reveals that the aggregation of FUS protein is a central component of ALS and FTD. In healthy nerve cells, FUS is transported into the nucleus where it regulates DNA and RNA processing, but in neurons affected by ALS and FTD, its transport is compromised, leading to cytoplasmic aggregation.
