Scientists discover key to preventing neurodegeneration in Parkinson's and related disorders

A team of researchers has uncovered a groundbreaking mechanism in the formation of harmful protein aggregates that lead to neurodegenerative diseases such as Parkinson's Disease. The team, led by Professor Norifumi Shioda and Associate Professor Yasushi Yabuki, identified for the first time that unique RNA structures called G-quadruplexes (G4s) play a central role in promoting the aggregation of alpha-synuclein, a protein associated with neurodegeneration. By demonstrating that inhibiting G4 assembly could potentially prevent the onset of synucleinopathies, this discovery positions G4 as a promising target for early intervention in these diseases.
