GCase, short for glucocerebrosidase, targets both lysosomal and mitochondrial dysfunction. In Parkinson’s, the failure of cellular powerhouses (mitochondria) and recycling centers (lysosomes) disrupts essential functions. This breakdown leads to a toxic buildup of glycosphingolipids (fatty substances within cells) and damaging clumps of alpha-synuclein (a misfolded protein), hallmarks of Parkinson’s disease and the cause of Lewy bodies. For a visual explanation of this process, see the diagram several par…
