Juvenile GM2 Gangliosidoses

Pediatric Neurology Briefs, 2006
Clinical features and genetic correlations of 21 new case histories and 134 published case reports of juvenile or subacute GM2 gangliosidosis were analyzed to delineate the natural history of the disorder, in a study at the Hospital for Sick Children ...

L-Arginine Ameliorates Defective Autophagy in GM2 Gangliosidoses by mTOR Modulation [PDF]

Cells, 2021
Aims: Tay–Sachs and Sandhoff diseases (GM2 gangliosidosis) are autosomal recessive disorders of lysosomal function that cause progressive neurodegeneration in infants and young children. Impaired hydrolysis catalysed by β-hexosaminidase A (HexA) leads to

Thymic alterations in GM2 gangliosidoses model mice. [PDF]

PLoS ONE, 2010
BACKGROUND: Sandhoff disease is a lysosomal storage disorder characterized by the absence of β-hexosaminidase and storage of GM2 ganglioside and related glycolipids.

Plasma neurofilament light, glial fibrillary acidic protein and lysosphingolipid biomarkers for pharmacodynamics and disease monitoring of GM2 and GM1 gangliosidoses patients [PDF]

Molecular Genetics and Metabolism Reports, 2022
GM2 and GM1 gangliosidoses are genetic, neurodegenerative lysosomal sphingolipid storage disorders. The earlier the age of onset, the more severe the clinical presentation and progression, with infantile, juvenile and late-onset presentations broadly ...

GM2 Gangliosidoses: Clinical Features, Pathophysiological Aspects, and Current Therapies [PDF]

International Journal of Molecular Sciences, 2020
GM2 gangliosidoses are a group of pathologies characterized by GM2 ganglioside accumulation into the lysosome due to mutations on the genes encoding for the β-hexosaminidases subunits or the GM2 activator protein. Three GM2 gangliosidoses have been described: Tay–Sachs disease, Sandhoff disease, and the AB variant. Central nervous system dysfunction is

A master protocol to investigate a novel therapy acetyl-l-leucine for three ultra-rare neurodegenerative diseases: Niemann-Pick type C, the GM2 gangliosidoses, and ataxia telangiectasia [PDF]

Trials, 2021
Background The lack of approved treatments for the majority of rare diseases is reflective of the unique challenges of orphan drug development. Novel methodologies, including new functionally relevant endpoints, are needed to render the development ...

GM1 and GM2 gangliosides: recent developments

Biomolecular Concepts, 2014
GM1 and GM2 gangliosides are important components of the cell membrane and play an integral role in cell signaling and metabolism. In this conceptual overview, we discuss recent developments in our understanding of the basic biological functions of GM1 ...

Critical role of iron in the pathogenesis of the murine gangliosidoses

Neurobiology of Disease, 2009
Neurodegeneration is a prominent feature of the gangliosidoses, a group of lysosomal storage diseases. Here we show altered iron homeostasis in mouse models of both GM1 and GM2 gangliosidoses, which are characterized by progressive depletion of iron in ...

Natural history study of glycan accumulation in large animal models of GM2 gangliosidoses.

PLoS ONE, 2020
β-hexosaminidase is an enzyme responsible for the degradation of gangliosides, glycans, and other glycoconjugates containing β-linked hexosamines that enter the lysosome. GM2 gangliosidoses, such as Tay-Sachs and Sandhoff, are lysosomal storage disorders

Evidence of Lysosomal β-Hexosaminidase Enzymatic Activity Associated with Extracellular Vesicles: Potential Applications for the Correction of Sandhoff Disease [PDF]

Journal of Functional Biomaterials
Extracellular vesicles (EVs) can be isolated from biological fluids and cell culture medium. Their nanometric dimension, relative stability, and biocompatibility have raised considerable interest for their therapeutic use as delivery vehicles of ...
