Background: Anti-ganglioside antibody assays are widely used for diagnosis of autoimmune peripheral neuropathies. Objective: This study aimed to determine serum levels of anti-ganglioside antibodies in children with Guillain-Barre syndrome by immunoblotting technique and compare the results with those obtained by ELISA method. Method: In this investigation, 50 children with Guillain-Barre syndr...

Ganglioside as a neurotrophic drug has been hitherto widely used in China, although Guillain-Barré syndrome (GBS) following intravenous ganglioside treatment was reported in Europe several decades ago. We identified 7 patients who developed GBS after intravenous use of gangliosides (ganglioside+ group) and compared their clinical data with those of 77 non-ganglioside-associated GBS patients (ga...

We developed a sensitive method for detection of glycosphingolipid (GSL) antigen(s) on the cell surface. As a model of GSL antigen, ganglioside GD3 was used. An IgM monoclonal antibody (DSG-1) specific for ganglioside GD3 was preincubated with standard inhibitor liposomes containing ganglioside GD3. Then carboxyfluorescein-entrapped indicator liposomes containing ganglioside GD3 and complement ...

Ganglioside stimulated neurite outgrowth may be due to ganglioside binding to membrane proteins or to intercalation into the membrane. To test that ganglioside binding proteins could be found on neuronal surfaces, anti-idiotypic ganglioside monoclonal antibodies (AIG mAbs) were generated to mimic the biological properties of the GM1 ganglioside. The AIG mAbs were identified by their ability to ...

BACKGROUND Anti-ganglioside antibodies with a pathogenic potential are present in C. jejuni-associated Guillain-Barré syndrome (GBS) patients and are probably induced by molecular mimicry. Immunization studies in rabbits and mice have demonstrated that these anti-ganglioside antibodies can be induced using purified lipo-oligosaccharides (LOS) from C. jejuni in a strong adjuvant. METHODOLOGY/P...

TGF-β (transforming growth factor-β)-induced EMT (epithelial-mesenchymal transition) induces the proliferation and migration of the HLE (human lens epithelial) cells. Ganglioside GM3, simple sialic-acid-containing glycosphingolipids on mammalian cell membranes, regulates various pathological phenomena such as insulin resistance and tumour progression. However, the relationship between gangliosi...

Botulinum Neurotoxins (BoNTs) are organized into seven serotypes, A-G. Although several BoNT serotypes enter neurons through synaptic vesicle cycling utilizing dual receptors (a ganglioside and a synaptic vesicle-associated protein), the entry pathway of BoNT/D is less well understood. Although BoNT/D entry is ganglioside-dependent, alignment and structural studies show that BoNT/D lacks key re...

SEE VAN DOORN AND JACOBS DOI101093/BRAIN/AWW078 FOR A SCIENTIFIC COMMENTARY ON THIS ARTICLE  : In axonal forms of Guillain-Barré syndrome, anti-ganglioside antibodies bind gangliosides on nerve surfaces, thereby causing injury through complement activation and immune cell recruitment. Why some nerve regions are more vulnerable than others is unknown. One reason may be that neuronal membranes wi...

In order to evaluate the usefulness of liposomes, which are stable in acidic solution, bile and pancreatin solution (stable liposomes), as vehicle for oral vaccines, the intestinal IgA antibody responses of mice to liposome-associated antigen after oral administration were examined. The intestinal IgA antibody responses against ganglioside GM1 were detected after the oral immunization of gangli...
