BACKGROUND AND PURPOSE No previous studies have investigated the relationship between various anti-ganglioside antibodies and the clinical characteristics of Guillain-Barré syndrome (GBS) in Korea. The aim of this study was to determine the prevalence and types of anti-ganglioside antibodies in Korean GBS patients, and to identify their clinical significance. METHODS Serum was collected from ...
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 synd...
Guillain-Barré syndrome (GBS) is an acute immune-mediated polyradiculoneuropathy which can cause acute quadriplegia. Infection with micro-organisms, including Campylobacter jejuni (C. jejuni), Haemophilus influenzae, and Cytomegalovirus (CMV), is recognized as a main triggering event for the disease. Lipooligosaccharide (LOS) genes are responsible for the formation of human ganglioside-like LOS...
In this study we characterized the IgG antibodies against lipopolysaccharides (LPS) of Campylobacter jejuni in serum from patients with Guillain-Barré syndrome (GBS), Miller Fisher syndrome (MFS), C. jejuni enteritis and normal controls. In patients with GBS and MFS long-lasting titers of IgG1 and IgG3 antibodies against LPS from GBS and MFS associated C. jejuni were found. The subclass and cou...
Localization of ganglioside GM1 in cholinergic neurons from the septal area of a primary culture newborn rat brain was studied with a double avidin-biotin complex system. Cholinergic neurons were identified by double immunolabeling techniques that use choline acetyltransferase (ChAT) and neurofilament (NF) protein-antibodies. ChAT-positive neurons also were stained for ganglioside GM1 by using ...
The neurophysiological effects of nine neuropathy-associated human anti-ganglioside antisera, three monoclonal antibodies to ganglioside GM1 (GM1) and of the cholera toxin B subunit (a GM1 ligand) were studied on mouse sciatic nerve in vitro. GM1 antisera and monoclonal antibodies from patients with chronic motor neuropathies and Guillain-Barre syndrome, and GQ1b/ disialosyl antisera and monocl...
Guillain-Barré syndrome is a postinfectious, autoimmune neuropathy resulting in neuromuscular paralysis. Auto-antibodies, often induced by bacterial infection, bind to human gangliosides possessing monosialoside and diasialoside epitopes and impair the function of nerve junctions, where these ganglioside structures are highly enriched. Truncated gangliosides representive of GD3, GQ1b and GM2 ep...
Glycosphingolipids are ubiquitous membrane constituents that are subdivided in neutral or acidic fractions (gangliosides and sulfatides). Their analysis requires extraction and separation by thin-layer chromatography or high-performance liquid chromatography. Ganglioside composition changes occur in response to variations in cellular morphology and function. Glycosphingolipids are implicated in...
