Description
While the study establishes LRRK2’s role in suppressing lysosomal degradation, it doesn’t demonstrate whether this mechanism directly contributes to the hallmark pathology of Parkinson’s disease. This connection is essential for validating lysosomal enhancement as a therapeutic strategy.
