More than 60 gangliosides are known, which differ from each other mainly in the position and number of NANA residues. It is a component of the cell plasma membrane that modulates cell signal transduction events, and appears to concentrate in lipid rafts [2] [3]. Recently, gangliosides have been found to be highly important molecules in ...
The numbering is based on its relative mobility in electrophoresis among other monosialic gangliosides. [1] Its structure can be condensed to NANA - Gal - Glc - ceramide . GM3 is the most common membrane-bound glycosphingolipid in tissues, composed of three monosaccharide groups attached to a ceramide backbone. [ 2 ]
Beta-hexosaminidase is a vital hydrolytic enzyme, found in the lysosomes, that breaks down lipids. When beta-hexosaminidase is no longer functioning properly, the lipids accumulate in the nervous tissue of the brain and cause problems. Gangliosides are made and biodegraded rapidly in early life as the brain develops.

Calcification can manifest itself in many ways in the body depending on the location. In the pulpal structure of a tooth, calcification often presents asymptomatically, and is diagnosed as an incidental finding during radiographic interpretation. Individual teeth with calcified pulp will typically respond negatively to vitality testing; te
The GM1 gangliosidoses, usually shortened to GM1, are gangliosidoses caused by mutation in the GLB1 gene resulting in a deficiency of beta-galactosidase.The deficiency causes abnormal storage of acidic lipid materials in cells of the central and peripheral nervous systems, but particularly in the nerve cells, resulting in progressive neurodegeneration.
Antibodies to ganglioside are found to be elevated in coeliac disease. [16] Recent studies show that gliadin can cross-link to gangliosides in a transglutaminase independent manner, indicating that gliadin specific T-cell could present these antigens to the immune system. [17]
Gangliosidosis contains different types of lipid storage disorders [1] caused by the accumulation of lipids known as gangliosides. There are two distinct genetic causes of the disease. Both are autosomal recessive and affect males and females equally.
