[Research Focus]
Neurodegenerative diseases are turning into global health issues. A common pathological signature of such diseases is abnormal protein aggregation in the brain. Dys-regulated phase transitions of protein and other biological macromolecules underlie the formation of such aggregation: under physiological conditions, certain proteins go through liquid-liquid phase separation to form membrane-less organelles, thereby partitioning the intracellular space and accurately orchestrating various biochemical reactions; during pathogenesis, abnormal phase transition of such proteins produce insoluble protein aggregation, which in turn, lead to neuronal cell death. We are investigating the phase transition of biological macromolecules in several aspects, including the molecular mechanism and its physiological role in the nervous system. Our ultimate goal is to develop novel therapeutic approaches through intervening pathological phase transitions.
