Does LRRK2's role as a lysosomal volume sensor explain the pathogenic mechanism of disease-linked LRRK2 mutations?

PARTIALLY ADDRESSED

While the study establishes LRRK2 as a lysosomal swelling sensor and notes that lysosomal swelling occurs in LRRK2-linked diseases, it doesn't directly test whether pathogenic LRRK2 mutations alter this volume-sensing function. This connection is crucial for understanding how LRRK2 mutations cause Parkinson's disease and related disorders. Gap type: open_question Source paper: Lysosomal swelling triggers LRRK2 activity.
