Abstract
GM3 is a simple monosialylated ganglioside (NeuAcα(2-3)Galβ(1-4)Glcβ1-1'-ceramide). Its aberrant expression in adipocytes is involved in a variety of physiological and pathological processes in diabetes mellitus and obesity. GM3 is exposed on the outer surface of cell membranes and is strongly associated with type 2 diabetes and insulin resistance. Exogenously added GM3 promotes neurite outgrowth in a variety of different neuroblastoma cell lines. Neurite outgrowth is a key process in the development of functional neuronal circuits and neuro-regeneration following nerve injury. Therefore, regulating GM3 levels in nerve tissues might be a potential treatment method for these disorders. Here, we demonstrate the comprehensive synthesis of stereoisomeric GM3s and compare their physicochemical properties with those of natural GM3 and diastereomers of sphingolipids in GM3 to examine the enhancement of biological activity. l-erythro-GM3 was confirmed to increase neurite outgrowth, providing valuable insights for potential neuro-regenerative treatments.

Abstract
Spinal cord injuries (SCIs) pose an immense challenge from a clinical perspective as current treatments and interventions have been found to provide marginal improvements in clinical outcome (with varying degrees of success) particularly in areas of motor and autonomic function. In this review, the pathogenesis of SCI will be described, particularly as it relates to the necroptotic pathway which has been implicated in limiting recovery of SCI via its roles in neuronal cell death, glial scarring, inflammation, and axonal demyelination and degeneration. Major mediators of the necroptotic pathway including receptor-interacting protein kinase 1, receptor-interacting protein kinase 3, and mixed-lineage kinase domain-like will be described in detail regarding their role in facilitating necroptosis. Additionally, due to the rapid accumulation of reactive oxygen species and inflammatory markers, the onset of necroptosis can begin within hours following SCI, thus developing therapeutics that readily cross the blood-brain barrier and inhibit necroptosis during these critical periods of inflammation are imperative in preventing irreversible damage. As such, current therapeutic interventions regarding SCI and targeting of the necroptotic pathway will be explored as will discussion of potential future therapeutics that show promise in minimizing long-term or permanent damage to the spinal cord following severe injury.

Abstract
BACKGROUND Depression is a serious psychiatric disorder that easily causes physical impairments and a high suicide rate. Monosialotetrahexosylganglioside is a crucial ganglioside for the central nervous system and has been reported to affect the function of the brain derived neurotrophic factor system. This study is aimed to evaluate whether monosialotetrahexosylganglioside has antidepressant-like effects. METHODS Antidepressant-like effects of monosialotetrahexosylganglioside were assessed in the chronic social defeat stress model of depression, and various behavioral tests were performed. Changes in the brain derived neurotrophic factor signaling pathway after chronic social defeat stress and monosialotetrahexosylganglioside treatment were also investigated. A tryptophan hydroxylase inhibitor and brain derived neurotrophic factor signaling inhibitors were used to determine the antidepressant mechanisms of monosialotetrahexosylganglioside. RESULTS Monosialotetrahexosylganglioside administration significantly reversed the chronic social defeat stress-induced reduction of sucrose preference and social interaction in mice and also prevented the increased immobility time in the forced swim test and tail suspension test. In addition, monosialotetrahexosylganglioside completely ameliorated the stress-induced dysfunction of brain derived neurotrophic factor signaling cascade in the hippocampus and medial prefrontal cortex, 2 regions closely involved in the pathophysiology of depression. Furthermore, the usage of brain derived neurotrophic factor signaling cascade inhibitors, K252a and anti-brain derived neurotrophic factor antibody, each abolished the antidepressant-like effects of monosialotetrahexosylganglioside, while the usage of a serotonin system inhibitor did not. CONCLUSIONS Taken together, our findings suggest that monosialotetrahexosylganglioside indeed has antidepressant-like effects, and these effects were mediated through the activation of brain derived neurotrophic factor signaling cascade.

Abstract
Growing evidence indicates that GQ1b, one of the gangliosides members, contributes to synaptic transmission and synapse formation. Previous studies have shown that GQ1b could enhance depolarization induced neurotransmitter release, while the role of GQ1b in asynchronous release is still largely unknown. Here in our result, we found low concentration of GQ1b, but not GT1b or GD1b (which were generated from GQ1b by plasma membrane-associated sialidases), evoked asynchronous dopamine (DA) release from both clonal rat pheochromocytoma PC12 cells and rat striatal slices significantly. The release peaked at 2 min after GQ1b exposure, and lasted for more than 6 min. This effect was caused by the enhancement of intracellular Ca(2+) and the activation of Pyk2. Inhibition of Pyk2 by PF-431396 (a dual inhibitor of Pyk2 and FAK) or Pyk2 siRNA abolished DA release induced by GQ1b. Moreover, Pyk2 Y402, but not other tyrosine site, was phosphorylated at the peaking time. The mutant of Pyk2 Y402 (Pyk2-Y402F) was built to confirm the essential role of Y402 activation. Further studies revealed that activated Pyk2 stimulated ERK1/2 and p-38, while only the ERK1/2 activation was indispensable for GQ1b induced DA release, which interacted with Synapsin I directly and led to its phosphorylation, then depolymerization of F-actin, thus contributed to DA release. In conclusion, low concentration of GQ1b is able to enhance asynchronous DA release through Pyk2/ERK/Synapsin I/actin pathway. Our findings provide new insights into the role of GQ1b in neuronal communication, and implicate the potential application of GQ1b in neurological disorders.

Abstract
Alzheimer's disease (AD) exerts a heavy health burden for modern society and has a complicated pathological background. The accumulation of extracellular β-amyloid (Aβ) is crucial in AD pathogenesis, and Aβ-initiated secondary pathological processes could independently lead to neuronal degeneration and pathogenesis in AD. Thus, the development of combination therapeutics that can not only accelerate Aβ clearance but also simultaneously protect neurons or inhibit other subsequent pathological cascade represents a promising strategy for AD intervention. Here, we designed a nanostructure, monosialotetrahexosylganglioside (GM1)-modified reconstituted high density lipoprotein (GM1-rHDL), that possesses antibody-like high binding affinity to Aβ, facilitates Aβ degradation by microglia, and Aβ efflux across the blood-brain barrier (BBB), displays high brain biodistribution efficiency following intranasal administration, and simultaneously allows the efficient loading of a neuroprotective peptide, NAP, as a nanoparticulate drug delivery system for the combination therapy of AD. The resulting multifunctional nanostructure, αNAP-GM1-rHDL, was found to be able to protect neurons from Aβ(1-42) oligomer/glutamic acid-induced cell toxicity better than GM1-rHDL in vitro and reduced Aβ deposition, ameliorated neurologic changes, and rescued memory loss more efficiently than both αNAP solution and GM1-rHDL in AD model mice following intranasal administration with no observable cytotoxicity noted. Taken together, this work presents direct experimental evidence of the rational design of a biomimetic nanostructure to serve as a safe and efficient multifunctional nanoplatform for the combination therapy of AD.

Abstract
Micro- and nanomolar concentrations of ganglioside GM1 improved viability of neuronal PC12 cells under conditions of oxidative stress and reduced H2O2-induced ROS accumulation in these cells. These effects were more pronounced at micromolar concentrations. GM1 in concentrations of 100 nM and 10 μM significantly and substantially increased basal activity of protein kinase B (Akt) (the level of phosphorylated Akt form), but had virtually no effect on its expression in PC12 cells. In the presence of PI3K inhibitor LY294002 preventing protein kinase Akt activation, the protective effect of GM1 significantly decreased. These findings suggest that activation of protein kinase Akt by GM1 contributes to improvement of PC12 cell viability by this ganglioside.

Abstract
Exogenous gangliosides are known to inhibit the effects of Escherichia coli lipopolysaccharide (LPS) in different cells exhibiting anti-inflammatory and immunosuppressive activities. The mechanisms underlying ganglioside action are not fully understood. Because LPS recognition and receptor complex formation occur in lipid rafts, and gangliosides play a key role in their maintenance, we hypothesize that protective effects of exogenous gangliosides would depend on inhibition of LPS signaling via prevention of TLR4 translocation into lipid rafts. The effect of GM1 and GD1a gangliosides on LPS-induced toxic and inflammatory reactions in PC12 cells, and in epithelial cells isolated from the frog urinary bladder, was studied. In PC12 cells, GD1a and GM1 significantly reduced the effect of LPS on the decrease of cell survival and on stimulation of reactive oxygen species production. In epithelial cells, gangliosides decreased LPS-stimulated iNOS expression, NO, and PGE2 production. Subcellular fractionation, in combination with immunoblotting, showed that pretreatment of cells with GM1, GD1a, or methyl-β-cyclodextrin, completely eliminated the effect of LPS on translocation of TLR4 into lipid rafts. The results are consistent with the hypothesis that ganglioside-induced prevention of TLR4 translocation into lipid rafts could be a mechanism of protection against LPS in various cells.

Abstract
Ganglioside GM1 at micro- and nanomolar concentrations was shown to increase the viability of pheochromocytoma PC12 cells exposed to hydrogen peroxide and diminish the accumulation of reactive oxygen species and oxidative inactivation of Na(+),K(+)-ATPase, the effects of micromolar GM1 being more pronounced than those of nanomolar GM1. These effects of GM1 were abolished by Trk receptor tyrosine kinase inhibitor and diminished by MEK1/2, phosphoinositide 3-kinase and protein kinase C inhibitors. Hydrogen peroxide activates Trk tyrosine kinase; Akt and ERK1/2 are activated downstream of this protein kinase. GM1 was found to activate Trk receptor tyrosine kinase in PC12 cells. GM1 (100 nM and 10 µM) increased the basal activity of Akt, but did not change Akt activity in cells exposed to hydrogen peroxide. Basal ERK1/2 activity in PC12 cells was increased by GM1 at a concentration of 10 µM, but not at nanomolar concentrations. Activation of ERK1/2 by hydrogen peroxide was enhanced by GM1 at a concentration of 10 µM and to a lesser extent at a concentration of 100 nM. Thus, the protective and metabolic effects of GM1 ganglioside on PC12 cells exposed to hydrogen peroxide appear to depend on the activation of Trk receptor tyrosine kinase and downstream activation of Akt and ERK1/2.

Abstract
Gangliosides play important roles in the control of several biological processes, including proliferation and transmembrane signaling. In this study, we demonstrate the effect of ganglioside GM1 on the proliferation of mouse induced pluripotent stem cells (miPSCs). The proliferation rate of miPSCs was lower than in mouse embryonic stem cells (mESCs). Fluorescence activated cell sorting analysis showed that the percentage of cells in the G2/M phase in miPSCs was lower than that in mESCs. GM1 was expressed in mESCs, but not miPSCs. To confirm the role of GM1 in miPSC proliferation, miPSCs were treated with GM1. GM1-treated miPSCs exhibited increased cell proliferation and a larger number of cells in the G2/M phase. Furthermore, phosphorylation of mitogen-activated protein kinases was increased in GM1- treated miPSCs.

In rodent models, ethanol triggers robust apoptotic neurodegeneration during a period of active synaptogenesis that occurs around the first two postnatal weeks, equivalent to the third trimester in human fetuses. The ethanol-induced apoptosis is mitochondria-dependent, involving Bax and caspase-3 activation. Such apoptotic pathways are often mediated by sphingolipids, a class of bioactive lipids ubiquitously present in eukaryotic cellular membranes. While the central role of lipids in ethanol liver toxicity is well recognized, the involvement of sphingolipids in ethanol neurotoxicity is less explored despite mounting evidence of their importance in neuronal apoptosis. Nevertheless, recent studies indicate that ethanol-induced neuronal apoptosis in animal models of FASD is mediated or regulated by cellular sphingolipids, including via the pro-apoptotic action of ceramide and through the neuroprotective action of GM1 ganglioside. Such sphingolipid involvement in ethanol neurotoxicity in the developing brain may provide unique targets for therapeutic applications against FASD. Here we summarize findings describing the involvement of sphingolipids in ethanol-induced apoptosis and discuss the possibility that the combined action of various sphingolipids in mitochondria may control neuronal cell fate.

Abstract
The prion protein (PrP) resides in lipid rafts in vivo, and lipids modulate misfolding of the protein to infectious isoforms. Here we demonstrate that binding of recombinant PrP to model raft membranes requires the presence of ganglioside GM1. A combination of liquid- and solid-state NMR revealed the binding sites of PrP to the saccharide head group of GM1. The binding epitope for GM1 was mapped to the folded C-terminal domain of PrP, and docking simulations identified key residues in the C-terminal region of helix C and the loop between strand S2 and helix B. Crucially, this region of PrP is linked to prion resistance in vivo, and structural changes caused by lipid binding in this region may explain the requirement for lipids in the generation of infectious prions in vitro.

Abstract
GM1 ganglioside was found to increase the survival of PC12 cells exposed to H(2)O(2), its action was blocked by Trk tyrosine kinase inhibitor K-252a. Thus, the inhibition of H(2)O(2) cytotoxic action by GM1 constituted 52.8 +/- 4.3%, but in the presence of 1.0 microM K-252a it was only 11.7 +/- 10.8%, i.e. the effect of GM1 became insignificant. Exposure to GM1 markedly reduced the increased accumulation of reactive oxygen species (ROS) and diminished the inactivation of Na(+),K(+)-ATPase induced in PC12 cells by H(2)O(2), but in the presence of K-252a GM1 did not change these metabolic parameters. The inhibitors of extracellular signal-regulated protein kinase, phosphatidyl inositol 3-kinase and protein kinase C decreased the effects of GM1. A combination of these protein kinase inhibitors reduced inhibition of H(2)O(2) cytotoxic action by GM1 to the larger extent than each of the inhibitors and practically abolished the ability of GM1 to decrease H(2)O(2)-induced ROS accumulation. The protective and antioxidative effects of GM1 in PC12 cells exposed to H(2)O(2) appear to be mediated by activation of Trk receptor tyrosine kinase and the protein kinases downstream from this enzyme.

Abstract
To address the role of brain gangliosides in synaptic plasticity, the synthetic ceramide analog, 1-phenyl-2-decanoylamino-3-morpholino-1-propanol (PDMP) was used to manipulate the biosynthesis of gangliosides in cultured cortical neurons. Spontaneous synchronized oscillatory activity of intracellular Ca(2+) between the neurons, which represents synapse formation, was suppressed by the depletion of endogenous gangliosides by d-threo-PDMP, an inhibitor of glucosylceramide synthase. On the other hand, the enantiomer of inhibitor, l-threo-PDMP, could elevate cellular levels of gangliosides by upregulating several glycosyltransferases responsible for ganglioside biosynthesis. This review presents our findings on the neurotrophic actions of l-threo-PDMP in vitro and in vivo. We found that l-PDMP could upregulate neurite outgrowth, and functional synapse formation through activating GM3, GD3, and GQ1b synthases. Simultaneously, the activity of p42 mitogen-activated protein kinase was also facilitated by l-PDMP. To evaluate the efficacy of this drug on long term memory, rats were trained for 2 weeks using an 8-arm radial maze task, and then forebrain ischemia was induced by four-vessel occlusion. Repeated treatment of l-PDMP starting 24h after the ischemia, improved the deficit of the well-learned spatial memory and prevented the ischemia-induced apoptosis in hippocampus, demonstrating the potential therapeutic use of the ceramide analog for treatment of neurodegenerative disorders.

Abstract
Glycosphingolipids (GSLs) are ubiquitous components of eukaryotic cell membranes. They are highly bioactive and are involved in many aspects of cell signalling like cell-cell interaction, cell-substratum interaction and cell-pathogen interaction. GSLs also are involved in the modulation of signal transduction, resulting in regulation of cell proliferation and differentiation. The biological importance and complexity of these compounds afford many opportunities to prepare synthetic analogues for studies of their metabolism in intra- and intercellular processes. This review focuses on recent contributions in the synthesis of GSLs, highlighting improvements in glycosylation reactions leading to alpha and beta glycosyl sphingosines and ceramides and related compounds. Literature from 2000 to the present is covered. The glycosylation reactions leading to the synthesis of GSLs are classified in function of the configuration of the created glycosidic bond (alpha or beta) and of the acceptor used, either azido-sphingosine or ceramide.

Abstract
Ganglioside GM1 was shown to increase the viability of PC12 cells exposed to hydrogen peroxide or amyloid beta-peptide (Abeta(25-35)). The PC12 cells transfected with mutant gene (expressing APP(SW)) were found to be more sensitive to oxidative stress than the cells transfected with wild type gene (expressing APP(WT)) or vector-transfected cells, GM1 being effective in enhancing the viability of the cells transfected with mutant gene. The exposure to hydrogen peroxide or Abeta(25-35) results in a partial inactivation of Na(+),K(+)-ATPase in PC12 cells, H(2)O(2) increases MDA accumulation in these cells. But these effects could be partially prevented or practically abolished by GM1 ganglioside. In the presence of the inhibitor of tyrosine kinase of Trk receptors (K-252a) the protective and metabolic effects of GM1 on PC12 cells in conditions of oxidative stress caused by hydrogen peroxide are not observed or are markedly diminished.

Abstract
Exogenous treatment with monosialoganglioside GM1 has been described to afford protection against different apoptotic insults. However, the underlying mechanisms remain to be determined. In this study, we focused on the effect of GM1 on the apoptotic cascade induced by benzo[a]pyrene (B[a]P) in rat hepatic F258 epithelial cells. We first demonstrated that a co-treatment with GM1 (80 microM) reduced B[a]P (50 nM)-induced apoptosis as evidenced by a decrease of both cell population exhibiting nuclear fragmentation and caspase 3 cleavage and activity. We next showed that the p53 phosphorylation and nuclear translocation as well as the intracellular alkalinization related to Na+/H+ exchanger 1 (NHE1) activation, two early events of the apoptosis induced by B[a]P, were not inhibited by GM1. In contrast, the late mitochondria-dependent acidification elicited by B[a]P was inhibited by GM1 co-treatment, and an inhibition of the oxidative stress was also observed. Because GM1 has been shown to reduce the low-molecular weight iron content related to ethanol-induced oxidative stress, we finally investigated the involvement of iron under our conditions. Using the two iron chelators deferiprone and desferrioxamine, we clearly showed that iron played an important role in B[a]P-induced apoptosis in F258 cells, and that B[a]P-treatment resulted in a significant GM1-sensitive increase in (55)Fe uptake. In conclusion, our results indicate that exogenous GM1 partly prevents B[a]P-induced apoptosis by interfering with mitochondria-related intracellular acidification and iron transport.

Abstract
GM1-ganglioside (GM1) is a major sialoglycolipid of neuronal membranes that, among other functions, modulates calcium homeostasis. Excessive accumulation of GM1 due to deficiency of lysosomal beta-galactosidase (beta-gal) characterizes the neurodegenerative disease GM1-gangliosidosis, but whether the accumulation of GM1 is directly responsible for CNS pathogenesis was unknown. Here we demonstrate that activation of an unfolded protein response (UPR) associated with the upregulation of BiP and CHOP and the activation of JNK2 and caspase-12 leads to neuronal apoptosis in the mouse model of GM1-gangliosidosis. GM1 loading of wild-type neurospheres recapitulated the phenotype of beta-gal-/- cells and activated this pathway by depleting ER calcium stores, which ultimately culminated in apoptosis. Activation of UPR pathways did not occur in mice double deficient for beta-gal and ganglioside synthase, beta-gal-/-/GalNAcT-/-, which do not accumulate GM1. These findings suggest that the UPR can be induced by accumulation of the sialoglycolipid GM1 and this causes a novel mechanism of neuronal apoptosis.

Abstract
A synthetic ceramide analog, L-threo-1-phenyl-2-decanoylamino-3-morpholino-1-propanol (L-PDMP) upregulates ganglioside biosynthesis in several cell lines. In cultured cortical neurons, neurotrophic effects of L-PDMP on neurite outgrowth and synaptic activity were demonstrated. In addition, it was found that L-PDMP could ameliorate the spatial cognition deficit in rats with ischemia. To elucidate this effect, we evaluated the effect of L-PDMP on brain ganglioside biosynthesis and its therapeutic efficacy against spatial cognition deficit in rats made ischemic. Rats were trained for 2 weeks, using an 8-arm radial maze task, and then forebrain ischemia was induced. L-PDMP was injected i.p. at 40 mg/kg twice a day starting from day 1 or 3 after ischemia induction for 6 or 4 days, respectively. The first study showed significantly reduced spatial cognition deficit at 12 h after the final drug administration, and L-PDMP tended to attenuate apoptosis in hippocampal CA1. To examine the effect of L-PDMP on brain ganglioside biosynthesis, N-[3H]acetyl-D-mannosamine was infused into the lateral ventricle via an injection cannula at 12 h after the final drug administration. After 4 h, the brain gangliosides were purified and analyzed. Upregulation of ganglioside biosynthesis by L-PDMP was observed on days 3 and 5 after ischemia. These results are an indication that L-PDMP may ameliorate spatial cognition deficit by upregulating ganglioside biosynthesis in ischemic brain.

Abstract
Glycosylphosphatidylinositol (GPI)-anchored proteins are clustered mainly in sphingolipid-cholesterol microdomains of the plasma membrane. The distribution of GPI-anchored fusion yellow fluorescent protein (GPI-YFP) in the plasma membrane of Chinese hamster ovary (CHO)-K1 cells with different glycolipid compositions was investigated. Cells depleted of glycosphingolipids by inhibiting glucosylceramide synthase activity or cell lines expressing different gangliosides caused by stable transfection of appropriate ganglioside glycosyltransferases or exposed to exogenous GM1 were transfected with GPI-YFP cDNA. The distribution of GPI-YFP fusion protein expressed at the plasma membrane was studied using the membrane-impermeable cross-linking agent bis(sulfosuccinimidyl)suberate. Results indicate that GPI-YFP forms clusters at the surface of cells expressing GM3, or cells depleted of glycolipids, or transfected cells expressing mainly GD3 and GT3, or GM1 and GD1a, or mostly GM2, or highly expressing GM1. However, no significant changes in membrane microdomains of GPI-YFP were detected in the different glycolipid environments provided by the membranes of the cell lines under study. On the other hand, wild type CHO-K1 cells exposed to 100 microm GM1 before cross-linking with bis(sulfosuccinimidyl)suberate showed a dramatic reduction in the amount of GPI-YFP clusters. These findings clearly indicate that manipulating the glycolipid content of the cellular membrane, just by changing the ganglioside biosynthetic activity of the cell, did not significantly affect the association of GPI-YFP on the cell surface of CHO-K1 cells. The effect of exogenous GM1 gangliosides on GPI-YFP plasma membrane distribution might be a consequence of the ganglioside level reached in plasma membrane and/or the effect of particular ganglioside species (micelles) that lead to membrane architecture and/or dynamic modifications.

Abstract
Plasma membrane-associated sialidase (Neu 3), which specifically hydrolyzes gangliosides, is relatively abundantly present in the nervous system. To understand the role of Neu 3 in neuronal differentiation, we studied the relationship between neurite outgrowth and Neu 3 expression in human neuroblastoma NB-1 cells. The expression of Neu 3 in NB-1 cells increased when neurite outgrowth in these cells was induced by dibutyryl cAMP. While treatment with dibutyryl cAMP alone enhanced the outgrowth of dendrite-like processes, transfection of the Neu 3 gave rise to a more prominent outgrowth of neurites with axon-like characteristics, even in the absence of dibutyryl cAMP. Neu 3 induction by dibutyryl cAMP is probably attributable, in part, to transactivation of the Neu 3 gene through cAMP responsive elements in the 5'-upstream region, as revealed by the promotor activity assay using Neu 3 promotor expression plasmid. These results indicate that Neu 3 regulates neurite formation in NB-1 cells, and suggest that this effect may be enhanced by dibutyryl cAMP via a cAMP-dependent pathway.

Abstract
Neurological dysfunction and structural cerebral abnormalities are commonly found in patients with methylmalonic and propionic acidemia. However, the mechanisms underlying the neuropathology of these disorders are poorly understood. We have previously demonstrated that methylmalonic and propionic acids induce a significant reduction of ganglioside N-acetylneuraminic acid in the brain of rats subjected to chronic administration of these metabolites. In the present study, we investigated the in vivo effects of chronic administration of methylmalonic (MMA) and propionic (PA) acids (from the 6th to the 28th day of life) on the distribution and composition of gangliosides in the cerebellum and cerebral cortex of rats. Control rats were treated with the same volumes of saline. It was first verified that MMA and PA treatment did not modify body, cerebellum, or cortical weight, nor the ganglioside concentration in the cerebral cortex of the animals. In contrast, a significant reduction in total ganglioside content in the cerebellum of approximately 20-30% and 50% of control levels occurred in rats injected with MMA and PA, respectively. Moreover, chronic MMA and PA administration did not interfere with the ganglioside pattern in the cerebral cortex, whereas the distribution of individual gangliosides was altered in the cerebellum of MMA- and PA-treated animals. Rats injected with MMA demonstrated a marked decrease in GM1 and GD3, whereas chronic PA treatment provoked a significant reduction of all ganglioside species, with the exception of an increase in GM2. Since gangliosides are closely related to the dendritic surface and other neural membranes, indirectly reflecting synaptogenesis, these ganglioside abnormalities may be associated with the brain damage found in methylmalonic and propionic acidemias.

Abstract
STUDY DESIGN Randomized, double-blind, sequential, multicenter clinical trial of two doses of Sygen versus placebo. OBJECTIVES To determine efficacy and safety of Sygen in acute spinal cord injury. SUMMARY OF BACKGROUND DATA An earlier, single-center trial in 28 patients showed an improvement (50.0% vs. 7.1%, P = 0.034) in marked recovery with Sygen. METHODS Standard clinical trial techniques. RESULTS The prospectively planned analysis at the prespecified endpoint time for all patients was negative. There was a significant effect in all patients in the primary outcome variable (the percentage of marked recovery) at week 8, the end of the dosing period. There was a significant effect in all patients in the time at which marked recovery is first achieved. Restricted to severity Group B, which has small sample size, the primary efficacy analysis showed a trend but did not reach significance. There is a large, consistent and, at some time points, significant effect in the primary outcome variable in the nonoperated patients through week 26. The American Spinal Injury Association motor, light touch, and pinprick scores showed a consistent trend in favor of Sygen, as also did bowel function, bladder function, sacral sensation, and anal contraction. The less severely injured patients appeared to have a greater beneficial drug effect. Evidence against an effect of Sygen was minimal and scattered. CONCLUSIONS Although not proven in the primary efficacy analysis of this trial, Sygen appears to be beneficial in patients with severe spinal cord injury.

Abstract
In a previous study we demonstrated that injection (i.p.) of low doses of GM1 ganglioside in mice rapidly attenuates morphine's analgesic effects. This result is consonant with our electrophysiologic studies in nociceptive types of dorsal root ganglion (DRG) neurons in culture, which showed that exogenous GM1 rapidly increased the efficacy of excitatory (Gs-coupled) opioid receptor functions. By contrast, treatment of DRG neurons with the non-toxic B-subunit of cholera toxin (CTX-B) which binds selectively to GM1, blocked the excitatory, but not inhibitory, effects of morphine and other bimodally-acting opioid agonists, thereby resulting in a net increase in inhibitory opioid potency. The present study provides more direct evidence that endogenous GM1 plays a physiologic role in regulating excitatory opioid receptor functions in vivo by demonstrating that cotreatment with remarkably low doses of CTX-B (10 ng/kg, s.c.) selectively blocks hyperalgesic effects elicited by morphine or by a kappa opioid agonist, thereby unmasking potent opioid analgesia. These results are comparable to the effects of cotreatment of mice with morphine plus an ultra-low dose of the opioid antagonist, naltrexone (NTX) which blocks opioid-induced hyperalgesic effects, unmasking potent opioid analgesia. Low-dose NTX selectively blocks excitatory opioid receptors at their recognition site, whereas CTX-B binds to, and interferes with, a putative allosteric GM1 regulatory site on excitatory opioid receptors. Furthermore, chronic cotreatment of mice with morphine plus CTX-B attenuates development of opioid tolerance and physical dependence, as previously shown to occur during cotreatment with low-dose NTX.

Abstract
After ventral root avulsion, a large percentage of the wounded spinal motoneurons die within 2 weeks. Neuronal death is preceded by a series of morphological and physiological changes probably as a result of both apoptotic and necrotic mechanisms. Associated with neuronal death, inflammation develops in the wounded area, resulting in additional neuronal loss as well as the degeneration of fibers from different tracts of the ventral and lateral funiculi. In the present study we tested the neuroprotective and local anti-inflammatory effects of monosialoganglioside (GM-1) after an initial 150 mg/kg body weight dose, followed by the daily administration of 100 mg/kg body weight for 2 weeks. The results showed a statistically significant enhancement of surviving motoneurons which showed good morphological preservation. Also, GM-1 treatment reduced by less then a half, the number of degenerating fibers into the ventral and lateral funiculi. Taken together, our results indicate that the administration of GM-1 in high doses during the critical period of motoneuron death after avulsion is neuroprotective, and diminishes local inflammation.

Abstract
Exposure of neonatal rats to a 5 Gy dose of X-irradiation induces permanent abnormalities in cerebellar cortex cytoarchitecture (disarrangement of Purkinje cells, reduction of thickness of granular cortex) and neurochemistry (late increase in noradrenaline levels), and motor function (ataxic gait). The neuroprotective effects of gangliosides have been demonstrated using a variety of CNS injuries, including mechanical, electrolytic, neurotoxic, ischemic, and surgical lesions. Here, we evaluated whether systemically administered GM1 ganglioside protects against the long-term CNS abnormalities induced by a single exposure to ionizing radiation in the early post-natal period. Thus, neonatal rats were exposed to 5 Gy X-irradiation, and subcutaneously injected with one dose (30 mg/kg weight) of GM1 on h after exposure followed by three daily doses. Both at post-natal days 30 and 90, gait and cerebellar cytoarchitecture in X-irradiated rats were significantly impaired when compared to age-matched controls. By contrast, both at post-natal days 30 and 90, gait in X-irradiated rats that were treated with GM1 was not significantly different from that in non-irradiated animals. Furthermore, at post-natal day 90, cerebellar cytoarchitecture was still well preserved in GM1-treated, X-irradiated animals. GM1 failed to modify the radiation-induced increase in cerebellar noradrenaline levels. Present data indicate that exogenous GM1, repeatedly administered after neonatal X-irradiation, produces a long-term radioprotection, demonstrated at both cytoarchitectural and motor levels.

Abstract
This review focuses on recent advances in our understanding of receptor-mediated signaling by the neurotrophins NGF, BDNF, NT3, and NT4/5. Two distinct receptor types have been distinguished, Trks and p75. The Trks are receptor tyrosine kinases that utilize a complex set of substrates and adapter proteins to activate defined secondary signaling cascades required for neurotrophin-promoted neuronal differentiation, plasticity, and survival. A specialized aspect of Trk/neurotrophin action in neurons is the requirement for retrograde signaling from the distal periphery to the cell body. p75 is a universal receptor for neurotrophins that is a member of the TNF receptor/Fas/CD40 superfamily. p75 appears to modify Trk signaling when the two receptor types are coexpressed. When expressed in the absence of Trks, p75 mediates responses to neurotrophins including promotion of apoptotic death. The mechanisms of p75 receptor signaling remain to be fully understood.

Abstract
GM3-synthase, also known as sialyltransferase I (ST-I), catalyzes the transfer of a sialic acid residue from CMP-sialic acid onto lactosylceramide to form ganglioside GM3. In order to clone this enzyme, as well as other sialyltransferases, we developed an approach that we termed combinatorial PCR. In this approach, degenerate primers were designed on the basis of conserved sequence motifs of the ST3 family of sialyltransferases (STs). The nucleotide sequence of the primers was varied to cover all amino acid variations occurring in each motif. In addition, in some primers the sequence was varied to cover possible homologous substitutions that are absent in the available motifs. A panel of cDNA from 12 mouse and 8 human tissues was used to enable cloning of tissue- and stage-specific sialyltransferases. Using this approach, the fragments of 11 new putative sialyltransferases were isolated and sequenced so far. Analysis of the expression pattern of a particular sialyltransferase across the panel of cDNA from the different tissues provided information about the tissue specificity of ST expression. We chose two new ubiquitously expressed human and mouse STs to clone full-length copies and to assay for GM3-synthase activity. One of the STs, which exhibited the highest homology to ST3 Gal III, showed activity toward lactosylceramide (LacCer) and was termed ST3 Gal V according to the suggested nomenclature [1]. The other ubiquitously expressed sialyltransferase was termed ST3Gal VI. All isolated sialyltransferases were screened for alternatively spliced forms (ASF). Such forms were found for both human ST3Gal V and ST3Gal VI in human fetal brain cDNA library. The detailed cloning strategy, functional assay, and full length cDNA and protein sequences of GM3 synthase (ST3Gal V, or ST-I) are presented.
