BACKGROUND Guillain-Barre syndrome (GBS) is a rare autoimmune disease characterized by acute, progressive peripheral neuropathy and is commonly associated with the presence of antiganglioside antibodies. Previously, influenza vaccination was linked with the increased incidence of GBS; however, whether antiganglioside antibodies are subsequently induced remains unresolved. METHODS Sera from hu...

We used flow cytometry to measure the expression of human melanoma antigens on cell suspensions dissociated from metastatic masses. The objective was to study the heterogeneity between tumor samples from different patients and between different tumors excised from a single patient. Fifty-three metastases excised from 34 melanoma patients were analyzed with a panel of nine murine monoclonal anti...

These included the lack of CSF albuminocytologic dissociation, the fact that the clinical signs occurred during the outbreak of pandemic (H1N1) 2009 virus infection rather than after it, and the fact that antibodies were not found in gangliosides. CSF albuminocytologic dissociation and serum ganglioside antibodies may be found in 85%–90% of Guillain-Barré syndrome patients (2). Alternatively, t...

A human Hanganutziu-Deicher (HD) antibody and a chicken anti-N-glycolyneuroaminyllactosylceramide (HD3) antibody were compared in their reaction against HD antigen-active ganglioside (HD3) and a glycoprotein (GP) by radioimmunoassay (RIA). The human antibody had a 50 times higher reactivity with the glycoprotein, while the chicken antibody reacted equally with both antigens. Both antibodies had...

In systemic lupus erythematosus (SLE), peripheral neuropathies are relatively uncommon and rarely present as the initial symptom. We herein describe a 61-year-old woman who developed a sudden onset of drop foot, which was indistinguishable from Guillain-Barré syndrome based on the clinical symptoms alone. Antibodies against ganglioside GM1 were detected in the serum, while no antibodies to Camp...

Target selection is a key feature in cancer immunotherapy, a promising field in cancer research. In this respect, gangliosides, a broad family of structurally related glycolipids, were suggested as potential targets for cancer immunotherapy based on their higher abundance in tumors when compared with the matched normal tissues. GD2 is the first ganglioside proven to be an effective target antig...

Recent studies suggest that increased T-cell and autoantibody reactivity to lipids may be present in the autoimmune demyelinating disease multiple sclerosis. To perform large-scale multiplex analysis of antibody responses to lipids in multiple sclerosis, we developed microarrays composed of lipids present in the myelin sheath, including ganglioside, sulfatide, cerebroside, sphingomyelin and tot...

A new technique capable of demonstrating the presence and cellular localization of the ganglioside GM1 in primary cultured cells from the brains of newborn rats is described. The method is based on the highly specific binding of biotinylated choleragen to ganglioside GM1, and takes advantage of the high affinity of avidin for biotin. Thus, the biotinylated choleragen-ganglioside GM1 complex can...
