Dysregulation of autophagy as a common mechanism in lysosomal storage diseases
The lysosome plays a pivotal role between catabolic and anabolic processes as the nexus for signalling pathways responsive to a variety of factors, such as growth, nutrient availability, energetic status and cellular stressors. Lysosomes are also the terminal degradative organelles for autophagy through which macromolecules and damaged cellular components and organelles are degraded. Autophagy ...
متن کاملAutophagy in lysosomal storage disorders
Lysosomes are ubiquitous intracellular organelles that have an acidic internal pH, and play crucial roles in cellular clearance. Numerous functions depend on normal lysosomes, including the turnover of cellular constituents, cholesterol homeostasis, downregulation of surface receptors, inactivation of pathogenic organisms, repair of the plasma membrane and bone remodeling. Lysosomal storage dis...
متن کاملLysosomal storage diseases
Lysosomes are cytoplasmic organelles that contain a variety of different hydrolases. A genetic deficiency in the enzymatic activity of one of these hydrolases will lead to the accumulation of the material meant for lysosomal degradation. Examples include glycogen in the case of Pompe disease, glycosaminoglycans in the case of the mucopolysaccharidoses, glycoproteins in the cases of the oligosac...
متن کاملClarifying lysosomal storage diseases.
Lysosomal storage diseases (LSDs) are a class of metabolic disorders caused by mutations in proteins critical for lysosomal function. Such proteins include lysosomal enzymes, lysosomal integral membrane proteins, and proteins involved in the post-translational modification and trafficking of lysosomal proteins. There are many recognized forms of LSDs and, although individually rare, their combi...
متن کاملStorage problems in lysosomal diseases.
Biochemical disorders in lysosomal storage diseases consist of the interruption of metabolic pathways involved in the recycling of the degradation products of one or several types of macromolecules. The progressive accumulation of these primary storage products is the direct consequence of the genetic defect and represents the initial pathogenic event. Downstream consequences for the affected c...
