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 ]
The secreted toxin attaches to the surface of the host mucosa cell by binding to GM1 gangliosides. GM1 consists of a sialic acid-containing oligosaccharide covalently attached to a ceramide lipid. The A1 subunit of this toxin will gain entry to intestinal epithelial cells with the assistance of the B subunit via the GM1 ganglioside receptor.
[5] [6] Gangliosides can be found on neuronal cells and are membrane proteins that aid in cell-cell recognition and communication. PglC belongs to a superfamily of enzymes known as monotopic phosphoglycsoyl transferases (monoPGT).
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.
Bone is a form of connective tissue found in the body, composed largely of hardened hydroxyapatite-containing collagen. In larger mammals, it is arranged in osteon regions. Bone matrix allows mineral salts such as calcium to be stored and provides protection for internal organs and support for locomotion.
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.
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]
