Abstract
The interactions of ganglioside GM1 with human and fetal calf sera were studied, the following main results being obtained: (a) GM1, upon incubation with both sera gave origin to two GM1-protein complexes, which also occurred after interaction of GM1 with the albumin fractions prepared from the same sera. Instead no complex formation occurred using the albumin-free fractions. Therefore GM1 appeared to specifically bind serum albumin and to form GM1-albumin complexes. (b) GM1 binding to serum albumin started at ganglioside concentrations surely micellar (above 10(-6) M), was time and concentration dependent, and resulted in a relevant degree of GM1 complexation (up to 80% of total GM1 in human serum and up to 18% in fetal calf serum). (c) the binding kinetics appeared, in both serum and the correspondent albumin fraction, to be biphasic: in the first phase, occurring till about 2 . 10(-4) M GM1, the ratio between bound and total GM1 increased linearly with increasing GM1 concentration; in the second phase, occurring above 2 . 10(-4) M, the ratio remained practically constant. After these findings it should be expected that GM1, when present in serum containing systems, forms complexes with albumin. This should be approximately considered when studying the effects of exogeneous GM1 in in vivo and in vitro (tissue cultures) systems.

Abstract
The involvement of gangliosides in processes related to nerve regeneration and sprouting has been demonstrated recently. The type of interaction by which gangliosides may influence neuronal sprouting was investigated in the present work. Affinity-purified rabbit anti-GM1 antibodies were found to block the sprouting from dorsal root ganglia (DRG) of chicken embryo induced by nerve growth factor (NGF). Only a moderately inhibitory effect was produced by antibodies directed to GM2, suggesting a specific interaction between NGF and GM1. In spite of the low inhibitory effect of anti-GM2 antibodies on sprouting, their binding to dissociated DRG cells was found to be higher than that of anti-GM1 antibodies. These results emphasize the high resolution of the system and suggest that the interaction of NGF with GM1 is involved in the process of sprouting.

Abstract
A phylogenetic survey of brain myelin ganglioside patterns and concentrations has been carried out on 16 vertebrate species. Gangliosides were isolated from purified myelin and found to vary in concentration from 25 micrograms of sialic acid per 100 mg of myelin for goldfish to a value of 395 for turkey. The latter species had approximately equivalent amounts of GM1 and GM4 as the two major gangliosides. The 11 mammals studied all had GM1 as the major ganglioside, with variable amounts of GM4; rhesus monkey and human had 20-25% GM4, whereas the others had less than 10%. Amphibia and fish myelin contained the least total ganglioside, with patterns that showed relatively little GM1 and no detectable GM4. Alligator myelin was unique in having a total concentration as high as the avian species, but a pattern with predominantly di- and trisialo gangliosides.

Abstract
The ganglioside patterns of cerebellum, cortex, pons-medulla, hypothalamus, hippocampus and caudate nucleus of three inbred strains of mice (C57BL/6J, DBA/2J and BALB/cJ) have been analysed. All brain areas contained both the simple and complex species of gangliosides. GD1a was the major ganglioside in cortex, hippocampus and caudate nucleus whereas GT1b was the major species in cerebellum, hypothalamus and pons-medulla. In hippocampus, the percentages of GT1b and GD1a were quite similar. Pons and medulla exhibited the highest levels of GM1 (which approaches the value of GT1b) and the lowest values of GD1a. A ganglioside, which was present in highest amounts in cerebellum disappeared after alkali treatment. Highly significant differences were observed in the amounts and patterns of gangliosides among brain areas of the three strains. Highly significant differences (p less than 0.001) were also found in the ganglioside distribution of various brain areas among the strains, especially for tri- and tetrasialogangliosides between Balb and DBA. A significant difference of GM1 was observed in the cerebellum when comparing DBA with the two other strains. It is likely that the differences might be related to their relative abundances in certain cell types and for defining synaptic circuits in brain areas of some strains.

Abstract
In 5-month-old chickens, an intracranial injection of N-[3H]acetylmannosamine led to a labeling of all optic lobe ganglioside species in a fashion paralleling the relative ganglioside distribution. In contrast, after an intraocular injection of the same precursor, the optic nerve and the optic lobe connected to the injected eye, possessed an exceptionally high labelling of GD1a (in comparison with GD1a-sialic acid), and only negligible incorporation of radioactivity into the myelin-specific GM4 and into a fraction migrating close to GM1. Subtracting both these very low labelling fractions from the total gave a percentage distribution of ganglioside sialic acid which now corresponded well to the distribution of radioactivity along the whole optic nerve, including the region of nerve terminals in the optic lobe. This pattern of ganglioside labelling, which indicates that GD1a carries about 60% of total ganglioside sialic acid of retinal ganglion cell axons, did not change remarkably during post-hatching development up to 5 months. Long-time incorporation studies revealed similar turnover rates of the main retinal ganglion cell gangliosides. The average half-lives were 34 (GD1a), 35 (GQ1b), 36.3 (GT1b) and 38.5 days (GD3). The findings suggest that the retinal ganglion cell axons and their presynaptic terminals possess a similar ganglioside pattern, characterized by a high content of GD1a.

Abstract
To study ganglioside distribution within subcellular components and test the hypothesis that they are localized at the nerve ending, microsomes and synaptic plasma membranes were isolated from young adult rat brains and compared with respect to ganglioside composition. These were shown to be heterogeneous preparations by fractionation on a discontinuous sucrose gradient into subfractions which had differing ganglioside concentrations. The highest ganglioside concentrations occurred in membranes banding at the 0.8M/1.0M and 1.0M/1.3M interfaces for both microsomes and synaptic plasma membranes. These subfractions had closely similar ganglioside concentrations and pattern distributions. In addition, the kinetics of ganglioside labeling following administration of [3H]-glucosamine were similar for the two preparations. The fact that microsomal subfractions representing heterogeneous mixtures of brain cell membranes showed close similarity to synaptosomal plasma membranes argues against localization of gangliosides at the nerve ending. These results, together with other lines of evidence, support the concept that gangliosides are distributed over large portions of the neuron (and perhaps other brain cells). Data concerning the labeling of gangliosides in different microsomal subfractions indicated a movement of label over time from the more dense to the less dense membranes, as was also noted for the glycoproteins in the same subfractions. Specific radioactivity of the gangliosides increased relative to that of the glycoproteins with time.

Abstract
1. Rat dams given a diet containing 100 g maize oil/kg for approximately two weeks before mating and during the first 14 d of gestation, were given the same diet or one containing 100 g hydrogenated coconut oil/kg (essential fatty acid (EFA)-deficient) in place of maize oil until parturition. After parturition the dams were given the same diets and all progeny were weaned to the maize oil diet at 21 d of age. Brain N-acetylneuraminic acid (NeuNAc) content as well as neuraminidase (sialidase; (EC 3.2.1.18), and cytidine monophosphate N-acetylneuraminic acid synthetase (CMP-NeuNAc synthetase) activities were measured at days, 7, 14, 21 and 168 in the progeny. Y-maze learning was measured at 168 d. 2. Brain weight was independent of dietary fat at all ages. 3. Lack of EFA in the maternal diet during gestation and lactation depressed ganglioside and glycoprotein NeuNAc levels and the activities of sialidase and CMP-NeuNAc synthetase. 4. Maternal dietary deprivation of EFA irreversibly impaired learning behaviour of the progeny. A relationship exists between early exposure to EFA deficiency and learning potential of the progeny.

Abstract
1. This study investigated the subcellular localization of injected N-acetylneuraminic acid (NeuNAc) in brain. Forty pregnant rats were distributed into four groups. Two groups were given a 200 g casein/kg diet and the other two groups a 100 g casein/kg diet throughout gestation. One group from each of the low- and high-protein groups were given their respective diets for the first 11 d of lactation. On day 12 of lactation, 2.5 microCi [14]NeuNAc/kg body-weight were injected intraperitoneally into their pups. After 1 h the pups were killed, their brains removed and subjected to subcellular fractionation. On day 16 of lactation the other two groups were similarly treated. 2. In all groups of animals 80% of the [14C]NeuNAc incorporated into the brains was found in the synaptosomal fraction and the remainder distributed among the other subcellular fractions in proportion to their total NeuNAc content. 3. These results suggest that NeuNAc exerts its effects on behaviour via the synaptic membrane.

Abstract
GM1 ganglioside binding to the crude mitochondrial fraction of rat brain and its effect on (Na+, K+)-ATPase were studied, the following results being obtained: (a) the binding process followed a biphasic kinetics with a break at 50 nM-GM1; GM1 at concentrations below the break was stably associated, while over the break it was loosely associated; (b) stably bound GM1 activated (Na+, K+)-ATPase up to a maximum of 43%; (c) the activation was dependent upon the amount of bound GM1 and was highest at the critical concentration of 20 pmol bound GM1 X mg protein-1; (d) loosely bound GM1 suppressed the activating effect on (Na+, K+)-ATPase elicited by firmly bound GM1; (e) GM1-activated (Na+, K+)-ATPase had the same pH optimum and apparent Km (for ATP) as normal (Na+, K+)-ATPase but a greater apparent Vmax; (f) under identical binding conditions (2 h, 37 degrees C, with 40 nM substance) all tested gangliosides (GM1, GD1a, GD1b, GT1b) activated (Na+, K+)-ATPase (from 26-43%); NeuNAc, sodium dodecylsulphate, sulphatide and cerebroside had only a very slight effect. It is suggested that the ganglioside activation of (Na+-K+)-ATPase is a specific phenomenon not related to the amphiphilic and ionic properties of gangliosides, but due to modifications of the membrane lipid environment surrounding the enzyme.

Abstract
The occurrence of gangliosides on nerve cells of the developing retina was studied by fluorescence-activated cell analysis and sorting, using fluorescent cholera toxin as marker. This toxin binds to GM1; neuraminidase converts several other gangliosides into GM1. Without pretreatment by this enzyme weak binding of toxin is detected at later stages of development, whereas pretreatment leads to considerable toxin binding at earlier stages. The number of cells binding toxin as well as the amount bound per cell increase with developmental age of the retina. Cells binding a given amount of toxin vary strongly in size. Cell sorting was used to separate postmitotic cells from proliferating cells. Proliferating cells have little binding capacity, while postmitotic cells bind relatively large amounts of toxin. Localization of gangliosides which bind toxin in the developing retina was studied in cryostat sections. At an early stage (day 6) toxin binding is localized in the inner layer of the developing retina which contains the ganglion and other postmitotic cells, but is not found in the outer layer of matrix cells. At later stages complex staining patterns evolve with binding predominantly in the nerve fiber layers.

Abstract
Gangliosides were extracted, separated by thin layer chromatography, and quantitated in three cranial nerves of the garfish (Lepisosteus osseus): the completely unmyelinated olfactory nerve (OLF), and two nerves composed of both myelinated and unmyelinated fibers, viz., the main trunk of the maxillary nerve (MAX) and a branch of the maxillary nerve (BR-MAX). Morphological studies on each of these nerves were done to verify that the OLF had been excised free of any contamination from the accompanying myelinated BR-MAX, to aid in the interpretation of the biochemical findings, and to clarify the nature of the OLF supporting cell. The chief chemical findings were (1) documentation of the presence of gangliosides in nerves previously thought not to contain them, (2) demonstration that gangliosides can be associated with unmyelinated nerves, (3) demonstration of a greater proportion of one simple ganglioside (G-6) in the OLF but greater proportions of two complex gangliosides (G-2 and G-0) in the MAX and BR-MAX, and (4) that either GM4 or a variant of the GM3 is present in OLF. The morphological findings with respect to the difficulty of ascribing only peripheral nervous system characteristics to the OLF supporting cell are discussed in relation to the ganglioside band chromatographing slightly ahead of GM4 in the OLF.

Abstract
Gangliosides in the external surface of intact synaptosomes from rat brain cortex have been studied by oxidation of exposed galactose and galactosamine groups with galactose oxidase followed by reduction with labeled sodium borohydride. Purified synaptosomes were labeled, disrupted by osmotic shock, and the particulate components fractionated on diatrizoate to give four synaptosomal membrane fractions (A-D) and a mitochondrial pellet (E). Fractions A and B represent synaptosomal plasma membranes. When intact synaptosomes were labeled, the major portion of the total radioactivity incorporated into ganglioside fraction was found to be in GM1 3 species. With isolated membrane fractions little selectivity was seen: (1) more label was present compared to intact synaptosomes, and (2) zones corresponding to GM2, GM1, GD1a, GD1b were the major gangliosides labeled. The results confirm the conclusion that membrane fractions A and B are derived from the exposed synaptosome surface and also show that GM1 is the major ganglioside species available for enzyme oxidation at the surface.

Abstract
The present study deals with the developmental profile of cytosolic and membrane-bound gangliosides in rabbit whole brain from the 21st day of pregnancy, the time at which brain could be macroscopically recognized and handled, till birth. In this period of prenatal life the content of membrane-bound gangliosides showed a 2.5-fold increase, referred to fresh and dry brain weight and to membrane-bound protein; the content of cytosolic gangliosides reached a maximum at 21-22 days of pregnancy, and then underwent to birth a threefold diminution. The qualitative pattern of membrane-bound gangliosides, in the same period of life, was characterized by an increase of GD1a and GM1 (more marked for GD1a), a decrease of GT1a, GT1b and GQ1b, and a constant level of GD3 and GD1b. At 21 days of pregnancy the most abundant gangliosides were GT1b and GQ1b, followed by GD1a and GD1b; at birth it was GD1a, followed by GT1b, GD1b and GM1. The qualitative pattern of cytosolic gangliosides closely resembled, during the entire period of prenatal life examined, that of membrane-bound gangliosides.

Abstract
There is a deficiency of human alpha-N-acetylneuraminidase in several inherited diseases. In patients with mucolipidosis I (refs 1,2) and in adults with a variant form with out bony abnormalities and mental retardation, both also classified as sialidoses, it is the only deficient enzyme. In mucolipidosis II ('I-cell' disease) neuraminidase is one of many deficient lysosomal hydrolases and a third manifestation combines deficiency of neuraminidase and beta-galactosidase. We have investigated the genetic background of these various neuraminindase deficiencies by somatic cell hybridization and co-cultivation. The principal conclusions from work on mutant fibroblasts, reported here, are that at least three gene mutations are involved and that the combined beta-galactosidase/neuraminidase deficiency is likely to be due to defective post-translational modification of these enzymes.

Abstract
Gangliosides GD3 and GM1 were coupled to proteins by their carboxyl groups and antisera were raised against the complexes. Anti-ganglioside antibodies were isolated by affinity chromatography on ganglioside-aminopropyl silica gel columns, and the specificity of the antibodies was determined by a quantitative microcomplement fixation assay. Antibodies to GD3 were highly specific and did not crossreact with GM3, lactosyl ceramide, or other glycolipids. Purified antibodies to GM1, in contrast, crossreacted with asialo-GM1, GD1b, and, to a lesser extent, GM2 and asialo-GM2. A derivative of GM1, containing a C-7 sialic acid residue produced by periodate oxidation, reacted with the ani-GM1 antibodies almost as readily as with GM1. The specificities of anti-GM1 antibodies elicited by the covalent ganglioside-protein complexes were similar to those produced by immunization with noncovalent complexes of GM1 and methylated bovine serum albumin. The ganglioside-protein complexes described here should be useful for preparing antibodies to polysialogangliosides that contain neuraminidase-sensitive linkages.

Abstract
Gangliosides were compared with glycoproteins as potential receptors for Sendai virus by incorporating measured amounts of the glycoconjugates into lecithin-cholesterol liposomes and measuring binding by a hemagglutination assay with sheep erythrocytes. HeLa cell gangliosides showed no binding activity toward the virus up to 15 micrograms of sialic acid per 5 mumol of lecithin-cholesterol, whereas HeLa cell glycoproteins incorporated into similar liposomes caused avid virus binding below 1 microgram of sialic acid. These sialoglycoproteins could be separated from the bulk of cell proteins by multiple chloroform-methanol extractions. Purified rat brain gangliosides at a level of 120 micrograms of sialic acid in liposomes did not bind virus, whereas chloroform-methanol-extracted rat brain proteins caused only marginal binding. Bovine brain gangliosides differed slightly from the rat brain mixture in showing weak binding properties. Our results thus indicate that glycoproteins, rather than gangliosides, are the natural receptors for Sendai virus and that tissues differ as to the quantity of such protein receptors.

Abstract
2The ganglioside compositions of the chick optic tectum and aggregating tectal cell cultures were examined. Both showed similar trends in changes in ganglioside patterns during development. GD3 and GD1b were the predominant gangliosides early in development, while GD1a and several other multisialogangliosides increased in relative amounts with increasing age in vivo and in vitro. Four gangliosides were present early in development which have not previously been reported. These gangliosides are not present at later developmental times suggesting a possible role for them during the critical early stages of nervous tissue differentiation. Some differences were noted when comparing in vivo versus in vitro ganglioside patterns; these differences may possibly be due to the lack of normal retinotectal connections in the cultures. Cytochemical studies on the localization of the presumed cholera toxin--peroxidase binding site GM1 showed conjugate binding correlates with increasing levels of GM1 in the cultures. In older cultures, the conjugate was uniformly localized on all cells and processes in the aggregates. The conjugate also bound to synaptic membranes and intensely stained the synaptic cleft. This latter observation suggests an enrichment of GM1 in the synaptic cleft region.

Abstract
The binding of d-tubocurarine by ganglioside mixtures from chicken and bovine brain as well as by the single gangliosides GGtet1-NeuAc, GGtet2aNeuAc and GGtet3aNeuAc was demonstrated by means of equilibrium gel filtration. The sialyl-oligosaccharide derivatives of GGtet1NeuAc and GGtet2aNeuAc, however, did not bind any d-tubocurarine. A lack of binding was also found for the gangliotetraosyl-ceramide GgOse4Cer, free NeuAc, mucin and sphingomyelin. Under saturation conditions, GGtet1NeuAc bound 0.58, GGtet2aNeuAc 0.92 and GGtet3a-NeuAc 1.23 mol d-tubocurarine per mol ganglioside. Half-maximal binding was achieved between 1 and 1.5 x 10(-5)M d-tubocurarine. Ca2 was found to inhibit the binding of d-tubocurarine to gangliosides (50% at 4 x 10(-4)M Ca2). Mg2 was about 4 times less effective. Acetylcholine caused a 40% inhibition at 4 x 10(-3)M, whereas K and Na had only slight effects even at 5 x 10(-2)M.

Abstract
The gangliosidoses comprise an-ever increasing number of biochemically and phenotypically variant diseases. In most of them an autosomal recessive inherited deficiency of a lysosomal hydrolase results in the fatal accumulation of glucolipids (predominantly in the nervous tissue) and of oligosaccharides. The structure, substrate specificity, immunological properties of and genetic studies on the relevant glycosidases, ganglioside GM1 beta-galactosidase and beta-hexosaminidase isoenzymes, are reviewed in this paper. Contrary to general expectation, only a poor correlation is observed between the severity of the disease and residual activity of the defective enzyme when measured with synthetic or natural substrates in the presence of detergents. For the understanding of variant diseases and for their pre- and postnatal diagnosis, the necessity of studying the substrate specificity of normal and mutated enzymes under conditions similar to the in vivo situation, e.g., with natural substrates in the presence of appropriate activator proteins, is stressed. The possibility that detergents may have adverse affects on the substrate specificity of the enzymes is discussed for the beta-hexosaminidases. The significance of activator proteins for the proper interaction of lipid substrates and water-soluble hydrolases is illustrated by the fatal glycolipid storage resulting from an activator protein deficiency in the AB variant of GM2-gangliosidosis. Recent somatic complementation studies have revealed the existence of a presumably post-translational modification factor necessary for the expression of ganglioside GM1 beta-galactosidase activity. This factor is deficient in a group of variants of GM1-glangliosidosis. Among the possible reasons for the variability of enzyme activity levels in heterozygotes and patients, allelic mutations, formation of hybrid enzymes, and the existence of patients as compound heterozygotes are discussed. All these may result in the production of mutant enzymes with an altered specificity for a variety of natural substrates.
