We used cholera toxin, which binds exclusively and with a high affinity to the ganglioside GM1, as a probe to investigate the distribution of this glycolipid on the surface of mouse lymphocytes. When lymphocytes are incubated with cholera toxin (or its B subunit) and then sequentially with horse anti-toxin and FITC-swine anti-horse Ig at 37°C, the cholera toxin-ganglioside GM1 complex is redist...
Clinical strategies which modulate the human anti-mouse antibody response (HAMA) in patients may have a profound influence on the idiotype network inducible by murine monoclonal antibodies (MoAb). Prior to myeloablative chemotherapy (ABMT), 9 patients with Stage IV neuroblastoma were imaged with 131I-3F8, a MoAb specific for the ganglioside GD2. Their serum HAMA, anti-idiotypic, anti-GD2, and a...
OBJECTIVES Several serum antibodies against gangliosides are diagnostically important, particularly in Guillain-Barré syndrome (GBS), Miller Fisher syndrome (MFS), and multifocal motor neuropathy (MMN). Although hyperreflexia is an atypical symptom in these disorders, it has been found in some patients with GBS, MFS, and MMN. The aim of the study was to determine whether hyperreflexia correspon...
Antibodies to GM1 ganglioside were used to study murine lymphocyte populations. In A, AKR, and BALB/c mice, anti-GM1 reacts with thymocytes and peripheral T cells. This reactivity of anti-GM1, studied by immunofluorescence, is independent of Thy-1 type and appears to be related to the reactivity of cross-reacting antibodies to asialo GM1 and GD1b, rather than GM1 itself. In addition, a subpopul...
A rapid assay for cholera toxin (CT) has been developed using a fluorescence-based biosensor. This sensor was capable of analyzing six samples simultaneously for CT in 20 min with few manipulations required by the operator. The biochemical assays utilized a ganglioside-"capture" format: ganglioside GM1, utilized for capture of analyte, was immobilized in discrete locations on the surface of the...
BACKGROUND/AIM Serum antibody against ganglioside GQ1b is reported to be closely associated with immune mediated ophthalmoplegia in the Fisher and Guillain-Barré syndromes. Its presence against glycolipids, in particular ganglioside GQ1b, was investigated in patients with ophthalmoplegia of unknown origin. METHODS 16 patients with ophthalmoplegia, the cause of which could not be confirmed fro...
Since the preliminary analyses of the glycolipids of small cell carcinomas of the lung showed an increase of GM2 ganglioside, we generated new murine monoclonal antibodies directed to GM2 to identify the molecular species of the glycolipid. The monoclonal antibodies MK2-34 and MK1-16 (both IgM), which specifically detect N-glycolyl GM2 and N-acetyl GM2, respectively, were generated by immunizin...
Abstract Background Parinaud’s syndrome, also known as dorsal midbrain is characterized by a combination of signs, including upgaze palsy, convergence–retraction nystagmus, eyelid retraction and pupillary dissociation. It caused pretectal or tegmental lesions upper brainstem. Miller Fisher the triad ataxia, areflexia ophthalmoplegia, has rarely been reported to present syndrome in adults. To ou...
This article presents a 6-year-old girl who developed acute unilateral third cranial nerve palsy in the absence of any other sign of central nervous system involvement. Raised titers of immunoglobulin M antibodies against GM1, GD1a, and GD1b ganglioside components were demonstrated. Ten days earlier, the girl had experienced acute gastroenteritis with positive specific immunoglobulin M antibodi...
