Abstract
Guillain-Barré syndrome (GBS) is an autoimmune polyneuropathy disease affecting the peripheral nervous system (PNS). Most of the GBS patients experienced neurological symptoms such as paresthesia, weakness, pain, and areflexia. There are also combinations of non-neurological symptoms which include upper respiratory tract infection and diarrhea. One of the major causes of GBS is due largely to the autoantibodies against gangliosides located on the peripheral nerves. Gangliosides are sialic acid-bearing glycosphingolipids consisting of a ceramide lipid anchor with one or more sialic acids attached to a neutral sugar backbone. Molecular mimicry between the outer components of oligosaccharide of gangliosides on nerve membrane and lipo-oligosaccharide of microbes is thought to trigger the autoimmunity. Intra-peritoneal implantation of monoclonal ganglioside antibodies secreting hybridoma into animals induced peripheral neuropathy. Recent studies demonstrated that injection of synthesized anti-ganglioside antibodies raised by hybridoma cells into mice initiates immune response against peripheral nerves, and eventually failure in peripheral nerve regeneration. Accumulating evidences indicate that the conjugation of anti-ganglioside monoclonal antibodies to activating FcγRIII present on the circulating macrophages inhibits axonal regeneration. The activation of RhoA signaling pathways is also involved in neurite outgrowth inhibition. However, the link between these two molecular events remains unresolved and requires further investigation. Development of anti-ganglioside antagonists can serve as targeted therapy for the treatment of GBS and will open a new approach of drug development with maximum efficacy and specificity.

Abstract
Gangliosides, sialic acid-bearing glycosphingolipids, are highly enriched in the vertebrate nervous system. Anti-ganglioside antibodies are associated with various human neuropathies, although the pathogenicity of these antibodies remains unproven. Testing the pathogenic role of anti-ganglioside antibodies will be facilitated by developing high-affinity IgG-class complement-fixing monoclonal anti-bodies against major brain gangliosides, a goal that has been difficult to achieve. In this study, mice lacking complex gangliosides were used as immune-naive hosts to raise anti-ganglioside antibodies. Wild-type mice and knockout mice with a disrupted gene for GM2/GD2 synthase (UDP-N-acetyl-D-galactosamine : GM3/GD3 N-acetyl-D-glactosaminyltransferase) were immunized with GD1a conjugated to keyhole limpet hemocyanin. The knockout mice produced a vigorous anti-GD1a IgG response, whereas wildtype littermates failed to do so. Fusion of spleen cells from an immunized knockout mouse with myeloma cells yielded numerous IgG anti-GD1a antibody-producing colonies. Ganglioside binding studies revealed two specificity classes; one colony representing each class was cloned and characterized. High-affinity monoclonal antibody was produced by each hybridoma : an IgG1 that bound nearly exclusively to GD1a and an IgG2b that bound GD1a, GT1b, and GT1aalpha. Both antibodies readily readily detected gangliosides via ELISA, TLC immune overlay, immunohistochemistry, and immunocytochemistry. In contrast to prior reports using anti-GD1a and anti-GT1b IgM class monoclonal antibodies, the new antibodies bound avidly to granule neurons in brain tissue sections and cell cultures. Mice lacking complex gangliosides are improved hosts for raising high-affinity, high-titer anti-ganglioside IgG antibodies for probing for the distribution and physiology of gangliosides and the pathophysiology of anti-ganglioside antibodies.

Abstract
Increased titers of IgM antibodies that react with carbohydrate epitopes on GM1 are present in some patients with lower motor neuron disease, sensorimotor neuropathy, or motor neuropathy with or without conduction block. Therapeutic reduction of antibody concentrations can result in clinical improvement, suggesting that the antibodies may be pathogenic. The anti-GM1 antibodies react with carbohydrate epitopes, which are shared by several other glycolipids and glycoproteins in the central and peripheral nervous system. The antibodies might exert their effects at a number of sites, depending on the topographical distribution of the target antigens and on their accessibility. B-cells that express anti-GM1 antibodies are present at birth and are normally suppressed or rendered anergic. Under some circumstances, however, they might be activated to secrete autoantibodies that cause autoimmune neuropathy.

Abstract
Antibodies to GM1 ganglioside enhance the release of gamma-aminobutyric acid (GABA) from rat brain slices induced by depolarization with either 40 mM K+ or 200 microM veratrine. Three new observations are now reported. (a) GABA release induced by the Ca2+ ionophore A23187 was not affected by these antibodies. Because this Ca2+ ionophore causes transmitter release by bypassing depolarization-induced opening of Ca2+ channels, this result suggests that gangliosides participate either in the functioning of such Ca2+ channels or in the Na+ channels involved in depolarization. (b) The enhancement (by antibodies to GM1 ganglioside) of GABA release induced by high K+ levels occurred in the presence of tetrodotoxin (0.01 microM). (c) GABA release induced by veratrine in the absence of Ca2+ was not affected by the antibodies. These latter two observations indicate that Na+ channels are not involved in the action of the antibodies. We conclude that this evidence points to the participation of gangliosides in Ca2+ channel functions involved in GABA release in rat brain slices.

Abstract
Polyclonal antibodies to ganglioside GM1 have been prepared and characterised by direct and competitive enzyme-linked immunoassay. An immunoglobulin fraction was prepared from a rabbit antisera showing high specificity and antibody titre for GM1 relative to the other major brain gangliosides. The anti-GM1 immunoglobulin fraction and B-cholera toxin specifically labelled neurons in primary cultures of embryonic chick dorsal root ganglia and there was a good correlation between the relative increase in binding of anti-GM1 immunoglobulin and B-cholera toxin following neuraminidase treatment of a variety of cell types. At antibody concentrations that show saturable binding to endogenous ganglioside in the neuronal membrane, the anti-GM1 immunoglobulin fraction did not interfere with the nerve growth factor (NGF)-mediated fibre outgrowth and neuronal survival as indexed by measurement of neurofilament protein levels. Similarly, at levels in excess of those shown to stimulate thymocyte proliferation, B-cholera toxin was also without effect. These data are not consistent with GM1 in the neuronal membrane functioning as a receptor molecule for NGF and/or other differentiation factors present in the tissue culture media.

Abstract
Eleven monoclonal antibodies to GM1 ganglioside were prepared from hybridoma clones obtained by fusion of spleen cells from mice immunized with GM1 with mouse myeloma cells. When the reactivities of these 11 monoclonal antibodies were determined by enzyme-linked immunosorbent assay with six glycosphingolipids (GM1, GD1a, GD1b, GT1b, GM2, and asialo-GM1), they showed different degrees of specificity. From their reactivity patterns, they could be divided into three groups: Group 1, those that react only with GM1 (C3 and D3); Group 2, those that react predominantly with GM1 (C6, B6, D1, e1, g1, g9, and e12); and Group 3, those that show poor discrimination (h2 and A4). The clones differed in their biological activities.

Abstract
Ganglioside-antisera, the ganglioside GM1-ligands, cholera toxin (CT), and CT subunit B, respectively, were injected into the lumbosacral subarachnoid space of normal rats. The cytotoxic effects of the injected compounds on the peripheral and central nervous system were investigated by light and electron microscopy; the severity of CNS lesions was evaluated by quantitation of macrophages containing debris. In contrast to control sera and GM2-antiserum, antisera against a mixture of the major brain gangliosides GM1, GD1a, GD1b, and GT1b (MaBG) or against GM1 induced demyelination in spinal roots and spinal cord, as well as alterations of astroglia. CT induced the same cytotoxic effects as MaBG- and GM1-antisera, whereas CT subunit B was without effect. The ineffectiveness of GM2-antiserum is obviously due to the very low concentration of the specific binding target, GM2, on cell surfaces; that of CT subunit B to the lack of the cytotoxic operator, subunit A. Our results indicate that a similar pattern of neuropathological lesions may be effected by different cytotoxic mechanisms through attachment of the cytotoxic agent onto the cell surface via a common target molecule, and further substantiate the role of GM1-antibodies in the pathogenesis of demyelination.

Abstract
Rabbits were immunized with nerve ending fraction prepared from guinea pig brain. Serum antibodies to total gangliosides were followed by enzyme-linked immunosorbent assay; their titers were highest at 2 to 3 weeks after immunization and some rabbits showed a response to reinjections. Specific reactivities of the antibodies against each molecular species of gangliosides were analyzed by liposome lysis assay and liposome lysis inhibition assay. Antibody responses were detected against GM1, GD1b, GM3 and GM2, but not against GD1a and GT1b. Natural and immune antibodies to the asialo glycolipids and to galactosylceramide were also observed.

Abstract
Antibodies to one or more glycosphingolipids were detected by means of a liposome lysis assay in the sera of 60/81 patients with multiple sclerosis, 24/42 patients with systemic lupus erythematosus and in the majority of patients with cranial trauma or cerebrovascular accidents. Antibodies against ganglioside GM1 and asialo GM1 were found most commonly and they were frequently present in the same sera. Among patients whose sera contained antibodies to glycolipids, anti-GM1 alone occurred more frequently in patients with multiple sclerosis (14/59) than in systemic lupus erythematosus (1/22; p = 0.045) and antiasialo GM1 alone was more common in patients with lupus (9/22) than in patients with multiple sclerosis (8/59, p = 0.007). In 10 sera analyzed, all of the antibodies against these two glycolipids were of the IgM class, and some fluctuation in antibody titers was noted over a three-month period. The role of these antibodies in the initiation or perpetuation of inflammatory diseases of the central nervous system remains to be determined.

Abstract
The effect of antibodies to GM1 ganglioside on release of neurotransmitters from rat brain slices was studied. Depolarization-induced (40 mM-KCl or veratrine) release of gamma-aminobutyric acid was markedly enhanced. Depolarization-induced release of norepinephrine was only slightly enhanced, whereas that of serotonin was unaffected. No effect on spontaneous release was observed for any of these three neurotransmitters. These results show that antibodies that can bind to synaptic membrane antigens may alter neurotransmitter release and that antibodies directed against GM1 ganglioside exhibit a measure of specificity in producing such an effect.

Abstract
Following observations that the intracerebral injection into rats of antiserum to brain gangliosides resulted in recurrent epileptiform activity and that seizure activity was not seen if antibodies were removed by absorption of the antiserum with pure GM1 ganglioside, a study was undertaken to establish characteristics of the immunological agents used to produce this model of epilepsy. It was determined that the potencies (antibody titers with GM1 ganglioside) of antiganglioside sera can be correlated with the intensities of epileptiform activity they induce; that immunoglobulin fractions from antiganglioside sera are even more effective biologically than the antisera; and that antibodies to GM1 ganglioside purified by affinity chromatography can also induce recurrent epileptiform discharges but are not as effective as either native antiserum or immunoglobulin fractions.
