Lysosomes are organelles of eukaryotic cells that are critically involved in the degradation of macromolecules mainly delivered by endocytosis and autophagocytosis. Degradation is achieved by more than 60 hydrolases sequestered by a single phospholipid bilayer. The lysosomal membrane facilitates interaction and fusion with other compartments and harbours transport proteins catalysing the export of...
Late endosomes and lysosomes (hereafter referred to as lysosomes) play an essential role in the turnover of cellular macromolecules and organelles. Their biochemical characterization has so far depended on purification methods based on either density gradient centrifugations or magnetic purification of iron‐loaded organelles. Owing to dramatic changes in lysosomal density and stability associated...
Niemann‐Pick C disease (NPC) is a neurodegenerative lysosomal disorder characterized by storage of cholesterol and other lipids caused by defects in NPC1, a transmembrane protein involved in cholesterol export from the lysosome, or NPC2, an intralysosomal cholesterol transport protein. Alterations in lysosomal activities have been implicated in NPC pathogenesis therefore the aim of this study was...
