Lysosomal storage disorders (LSDs) are a group of inherited metabolic diseases caused by dysfunction of the lysosomal system, with subsequent progressive accumulation of macromolecules, activation of inflammatory response, and cell death. Neurologic damage is almost always present, and it is usually degenerative.

Lysosomal Glycosphingolipid Storage Diseases
Annual Review of Biochemistry, 2019Glycosphingolipids are cell-type-specific components of the outer leaflet of mammalian plasma membranes. Gangliosides, sialic acid–containing glycosphingolipids, are especially enriched on neuronal surfaces. As amphi-philic molecules, they comprise a hydrophilic oligosaccharide chain attached to a hydrophobic membrane anchor, ceramide.

Lysosomal proteomics and disease
PROTEOMICS – Clinical Applications, 2007AbstractA recent trend in proteomic studies has been to analyze macromolecular complexes such as subcellular organelles instead of complete cells or tissues. This “divide and conquer” approach circumvents some of the formidable problems associated with whole proteome analyses and allows focus on a subset of proteins that may be involved in a particular

Lysosomal Storage Disease: Revealing Lysosomal Function and Physiology
Physiology, 2010The discovery over five decades ago of the lysosome, as a degradative organelle and its dysfunction in lysosomal storage disorder patients, was both insightful and simple in concept. Here, we review some of the history and pathophysiology of lysosomal storage disorders to show how they have impacted on our knowledge of lysosomal biology.

Abstract The lysosome is a ubiquitous, single membrane-bond intracellular organelle which continuously recycles biological macromolecules: it not only breaks down cell components but has a dynamic role in nutrient and energy sensing that, through regulatory signalling, is critical for homeostasis and metabolic economy of the cell ...

Lysosomal diseases: diagnostic update
Journal of Inherited Metabolic Disease, 2014AbstractTechnological developments in newborn and population screening, biomarker discovery for monitoring treatment and rapid high throughput DNA sequencing are having a great impact on the diagnostic procedure for symptomatic patients with lysosomal storage diseases.

[Lysosomes and lysosomal storage diseases].
Journal de la Societe de biologie, 2002Lysosomal storage disorders (LSDs) are monogenic inborn errors of metabolism. Various groups have been delineated according to the affected pathway and the accumulated substrate, and new entities are still being identified. They are severe disorders with a heterogeneous clinical spectrum encompassing visceral, skeletal and neurologic involvement, and ...

La Revue du praticien, 1994
Lysosomal diseases are severe genetic enzymopathies generally affecting the child, with a progressively fatal issue in the first few years of life. The group is very heterogeneous regarding: the number of included affections (about 30), as well as the clinical, biological and molecular manifestations.

[Lysosome disease--Sandhoff disease].
Nihon rinsho. Japanese journal of clinical medicine, 1993Lysosomal beta-hexosaminidase occurs as two major isozymes hexosaminidase A and B. The alpha subunit is encoded by the HEXA gene and the subunit by HEXB gene. Defects in the beta subunit lead to Sandhoff disease. Patients with the defect lack the activity or formation of both hexosaminidase A and B.
