Mixing brain cerebrosides with brain ceramides, cholesterol and phospholipids
The properties of bilayers composed of pure brain cerebroside (bCrb) or of binary mixtures of bCrb with brain ceramide, cholesterol, egg phosphatidylcholine or brain sphingomyelin have been studied using a combination of physical techniques. Pure bCrb exhibits a rather narrow gel-fluid transition centred at approximate to 65 degrees C with a half-width at half-height T-1/2 approximate to 3 degrees C. bCrb mixes well with both fluid and gel phospholipids and ceramide, and it rigidifies bilayers of egg phosphatidylcholine or brain sphingomyelin when the latter are in the fluid state. Cholesterol markedly widens the bCrb gel-fluid transition, while decreasing the associated transition enthalpy, in the manner of cholesterol mixtures with saturated phosphatidylcholines, or sphingomyelins. Laurdan and DPH fluorescence indicate the formation of fluid ordered phases in the bCrb:cholesterol mixtures. Macroscopic phase separation of more and less fluid domains is observed in giant unilamellar vesicles ...
The Effect of Cerebroside and Other Lipids on the Fixation of Tetanus Toxin by Gangliosides | Microbiology Society
SUMMARY: Water-insoluble complexes of ganglioside with cerebroside fixed tetanus toxin at low concentrations (a few LD 50/ml.) of toxin. A complex containing 25% ganglioside with cerebroside was 50 times better at fixing toxin than complexes containing either 2% or 50% ganglioside. A complex containing 25% of a mixture of the gangliosides Giii and Giv was 12 times better at fixing toxin than a similar complex with gangliosides Gi and GII. Complexes of ganglioside with sphingomyelin and lecithin fixed toxin to a slight extent, while complexes with tripalmitin and cholesterol did not fix toxin. The complex of cerebroside and ganglioside, containing 25% ganglioside, did not fix strychnine, serotonin, botulinum toxin or plasma albumin.

Cerebroside sulfatase: …called arylsulfatase A (ASA), or cerebroside sulfatase. Arylsulfatase A deficiency allows certain harmful sulfur-containing lipids, known as sulfosphingolipids (also called sulfatides), to accumulate in nerve tissues of the central nervous system instead of being broken down. Sulfatides can also accumulate in nerve tissue in organs, such as the kidneys and…
Inhibition of in vitro peripheral myelin formation by monoclonal anti-galactocerebroside.<...
TY - JOUR. T1 - Inhibition of in vitro peripheral myelin formation by monoclonal anti-galactocerebroside.. AU - Ranscht, B.. AU - Wood, P. M.. AU - Bunge, R. P.. PY - 1987/9. Y1 - 1987/9. N2 - This work investigates the role of galactocerebroside (GalC) in peripheral myelin formation. A monoclonal antibody against GalC was introduced into a myelinating culture system consisting of rat sensory neurons and Schwann cells, without other cell types. At levels that saturated Schwann cell surface GalC, anti-GalC IgG prevented by more than 99% the appearance of myelin sheaths. Ensheathment and basal lamina deposition were unaffected and many Schwann cells were in the 1:1 relationship that typically develops between Schwann cells and axons prior to myelination. Thus, the anti-GalC antibody did not interfere with the formation of the mesaxon but prevented its elongation. When experimentally restrained from myelination, Schwann cells did not accumulate the myelin proteins PO and basic protein; only low ...
Inhibition of entry of HIV-1 in neural cell lines by antibodies against galactosyl ceramide | Science
Although the CD4 molecule is the principal cellular receptor for the human immunodeficiency virus (HIV), several CD4-negative cell lines are susceptible to infection with one or more HIV strains. These findings indicate that there are alternate modes of viral entry, perhaps involving one or more receptor molecules. Antibodies against galactosyl ceramide (galactocerebroside, or GalC) inhibited viral internalization and infection in two CD4-negative cell lines derived from the nervous system: U373-MG and SK-N-MC. Furthermore, recombinant HIV surface glycoprotein gp120 bound to GalC but not to other glycolipids. These results suggest a role for GalC or a highly related molecule in HIV entry into neural cells. ...

The lipid composition of rat brain myelin and subcellular fractions during development | Biochemical Journal
1. The lipids of whole brain and subcellular fractions of the rat were analysed during development. 2. The deposition of cholesterol occurred in two phases, one related to increasing wet weight of the brain and the second to myelination. Cerebroside accumulation was related only to myelination. 3. The composition of myelin isolated from 12-day-old rat brain was different in some respects from that of the adult. In the former there was an increase of phospholipid in relation to cholesterol and a marked deficiency in cerebroside. 4. It is suggested that early myelin is extruded glial plasma membrane, which only later becomes mature myelin.. ...
Case Reports | Cryonics Institute
At the foundation of embalming is formalin, an aqueous solution saturated with formaldehyde gas, which constitutes 40% by volume and 37% by weight of the solution. Formaldehyde coagulates protoplasmic protein, turning it from a soft soluble form to a hard insoluble form which is resistant to both autolytic and bacterial proteolytic enzymes. Moreover, formaldehyde kills bacteria by coagulating bacterial protoplasm and has a drying effect upon tissue because of its strong affinity for water. Because formaldehyde preserves lipids as well as proteins, it would seem to be especially of value for the brain. A study of human brains preserved in formaldehyde for up to 24 years showed that the preservation of lipids was not uniform: cholesterol, cerebrosides, sulphatides, phosphoinositides and sphingomyelin remained unaffected, whereas lecithin, phosphatidylethanolamine and phosphadidylserine were broken down [THE JOURNAL OF HISTOCHEMISTRY AND CYTOCHEMISTRY; 10:704-709 (1962)].

Lipid composition of the stratum corneum and cutaneous water loss in birds along an aridity gradient
article{8f49d55d-b5f5-4f7b-bd69-f3ec250ab558, abstract = {Intercellular and covalently bound lipids within the stratum corneum (SC), the outermost layer of the epidermis, are the primary barrier to cutaneous water loss (CWL) in birds. We compared CWL and intercellular SC lipid composition in 20 species of birds from desert and mesic environments. Furthermore, we compared covalently bound lipids with CWL and intercellular lipids in the lark family (Alaudidae). We found that CWL increases in birds from more mesic environments, and this increase was related to changes in intercellular SC lipid composition. The most consistent pattern that emerged was a decrease in the relative amount of cerebrosides as CWL increased, a pattern that is counterintuitive based on studies of mammals with Gaucher disease. Although covalently bound lipids in larks did not correlate with CWL, we found that covalently bound cerebrosides correlated positively with intercellular cerebrosides and intercellular cholesterol ...

Extraction of control human spleen glucocerebrosidase with sodium cholate and butan-l-ol reversibly inactivates the enzyme in terms of its ability to hydrolyse the water-soluble substrate 4-methylumbelliferyl beta-D-glucopyranoside (MUGlc). The acidic brain lipid galactocerebroside 3-sulphate (sulphatide) reconstitutes beta-glucosidase activity in a strongly concentration-dependent manner. In this study we show that sulphatide exhibits three critical micellar concentrations (CMCs): CMC1, 3.72 microM; CMC2, 22.6 microM; CMC3, 60.7 microM. We designate the aggregates formed at these CMCs as primary, secondary and tertiary micelles respectively. From the results of kinetic studies performed at various sulphatide concentrations (0.012-248 microM), we found that sulphatide monomers (less than 3 microM) decreased the Km (for MUGlc) of control glucocerebrosidase from 11 to 4.6 mM, and lowered the Vmax. 2-fold. However, secondary and tertiary micelles were required for expression of high control ...
Imaging Study of the White Matter Lesions in Children With Metachromatic Leucodystrophy - Full Text View - ClinicalTrials.gov
Metachromatic Leukodystrophy (MLD) is a rare autosomal recessive disorder caused by the deficiency of the Arylsulfatase A enzyme (ARSA), resulting in accumulation of galactosyl sulfatide (cerebroside sulfate), a major constituent of the myelin sheath. Accumulation of sulfatides leads to a progressive degeneration of the white matter in the central and peripheral nervous systems (CNS, PNS) and to a neuronal degeneration. The late-infantile form of MLD, which is usually diagnosed in the second year of life, is the most frequent and severe form of the disease. The prognosis is severe, leading to vegetative stage or death within few years after the diagnosis. There is no treatment for patients affected with this early-onset form of the disease.. Conventional MRI (1.5 Tesla) shows extensive involvement of the cerebral white matter (hypo-T1, hyper- T2 and FLAIR signals) indicative of rapidly progressing leukodystrophy. Early cortical atrophy reflects associated neuronal involvement. Proton MR ...
Arylsulfatase A, 24 Hour, Urine - Mayo Medical Laboratories | Genetics and Pharmacogenomics Catalog
Metachromatic leukodystrophy (MLD) is a lysosomal storage disorder caused by a deficiency of the arylsulfatase A (ARSA) enzyme, which leads to the accumulation of galactosyl sulfatide (cerebroside sulfate) in the white matter of the central nervous system and in the peripheral nervous system. Galactosyl sulfatide and, to a smaller extent, lactosyl sulfatide, also accumulate within the kidney, gallbladder, and other visceral organs and are excreted in excessive amounts in the urine.. The 3 clinical forms of MLD are late-infantile, juvenile, and adult, depending on age of onset. All result in progressive neurologic changes and leukodystrophy demonstrated on magnetic resonance imaging. Late-infantile MLD is the most common (50%-60% of cases) and usually presents between age 1 to 2 years with hypotonia, clumsiness, diminished reflexes, and slurred speech. Progressive neurodegeneration occurs and most patients die within 5 years of the diagnosis. Juvenile MLD (20%-30% of cases) is characterized by ...

Patterns of lipid changes with growth of chick sciatic nerve
Phospholipids and cerebrosides of the normal chick sciatic nerve were extracted by Folch procedures and separated with silica gel thin-layer chromatography using various chloroform-methanol solvents. The subsequent chemical assays were expressed as a function of the developmental stages of the chick from 15 days of incubation to 7 days after hatching (28 days from onset of incubation). A histological study of chick sciatic nerves at ages 18, 20, 22 and 25 days was conducted to identify the period of myelination. Luxol Fast Blue G stain was used to identify the myelin. Myelin, is poorly identified at 18 days but notably present at 25 days. The assays of the phospholipids, expressed as relative percent of the total phospholipid phosphorus, indicated that ethanolamine-phosphoglyceride ratio increases significantly from 17 days to 23 days from onset. Sphingomyelin ratio also increased during this time, but not as much. While the relative amount of serinephosphoglyceride remained constant and ...

Sphingolipid - Wikipedia
Sphingolipids, or glycosylceramides, are a class of lipids containing a backbone of sphingoid bases, a set of aliphatic amino alcohols that includes sphingosine. They were discovered in brain extracts in the 1870s and were named after the mythological Sphinx because of their enigmatic nature. These compounds play important roles in signal transmission and cell recognition. Sphingolipidoses, or disorders of sphingolipid metabolism, have particular impact on neural tissue. A sphingolipid with an R group consisting of a hydrogen atom only is a ceramide. Other common R groups include phosphocholine, yielding a sphingomyelin, and various sugar monomers or dimers, yielding cerebrosides and globosides, respectively. Cerebrosides and globosides are collectively known as glycosphingolipids. The long-chain bases, sometimes simply known as sphingoid bases, are the first non-transient products of de novo sphingolipid synthesis in both yeast and mammals. These compounds, specifically known as ...
Arylsulfatase A - Wikipedia
Arylsulfatase A (or cerebroside-sulfatase) is an enzyme that breaks down sulfatides, namely cerebroside 3-sulfate into cerebroside and sulfate. In humans, arylsulfatase A is encoded by the ARSA gene. A deficiency is associated with metachromatic leukodystrophy, an autosomal recessive disease. Arylsulfatase A is inhibited by phosphate, which forms a covalent bond with the active site 3-oxoalanine.

Gauchers disease | Endocrine and metabolic diseases | ePharmaPedia
Causes:. A deficit of the enzyme glucocerebrosidase is the cause of Gauchers disease. Normally, this enzyme breaks down glucocerebrosides, which are fatty substances (lipids). However, these fatty substances could build up in someones brain and other organs and within the bone marrow in case the enzyme is scarce. Autosomal recessive is the inheritance pattern via which Gauchers disease is passed along. In order for a child to have the condition, both parents have to be carriers of a Gauchers genetic mutation. So far, more than 300 genetic mutations have been associated with this disease. Theres still only a 25% chance that the child will develop the disease even when both parents are carriers. Theres also a 25% chance that the child will not be a carrier and not have the disease, and a 50% chance that the child will be an unaffected carrier ...

Types A and B appear most often in Jewish families. Type C affects all ethnic groups and is the most common. Ataxia and dystonia are followed by supranuclear vertical gaze palsy, seizures, and dementia. Hepatosplenomegaly often coexists. Foamy (lipid-laden) cells or sea-blue histiocytes in the liver and bone marrow are diagnostic. Metachromatic Leukodystrophy (Arylsulfatase A or Saposin B Deficiency) Deficiency of arylsulfatase A or its activator, saposin B, leads to accumulation of cerebroside sulfate, which causes progressive (frontal-predominant) central and peripheral demyelination. ADHD affects about 5% of school-aged children worldwide, predominantly males (3:1 to 8:1). About one-third of ADHD cases have at least one ADHD parent. The risk to first-degree relatives of affected individual is 8-10 times that of the general population. ADHD persists into adolescence in about 30%-50% of affected individuals. The DSM-IV-TR distinguishes two dimensions in the behavior of individuals with ADHD: ...

Arylsulfatase A (ASA) is a lysosomal enzyme involved in the catabolism of cerebroside sulfate. ASA deficiency is associated with metachromatic leukodystrophy (MLD). Low ASA activities have also been reported in a more common condition with no apparent clinical consequences termed ASA pseudo-deficiency (ASA-PD) which is associated with two linked mutations in the ASA gene (c.1049A | G and c.*96A | G). This study aimed to investigate the frequency of the two ASA-PD variants and their linkage disequilibrium (LD) among Tunisians. ASA-PD variants were detected in 129 healthy Tunisians and their frequencies were compared to those described worldwide. The frequency of the PD allele was estimated at 17.4 % for the overall sample, with c.1049A | G and c.*96A | G frequencies of 25.6 and 17.4 %, respectively. This study also revealed a high LD between the two ASA-PD variants (r (2) = 0.61). Inter-population analysis revealed similarities in the ASA-PD genetic structure between Tunisians and populations from Middle

Question What is Gauchers disease?
Gauchers Disease* This disease was first described in the year 1882 by a French physician, Dr. Philippe C.E. Gaucher. As per him this disease or disorder takes place due to Accumulation of a particular lipid. Gaucher disease is basically defined as an inherited metabolic disorder (caused due to defective gene for the enzyme glucocerebrosidase from both parents) that leads to the accumulation of a particular fatty substance through out the body. Due to the accumulation of lipids in the body, it results in to deficiency of a particular enzyme acid beta-glucocerebrosidase which is necessary for the breakdown of a particular lipid- glucosyl ceramide. As the lipid accumulates, the glucosyl ceramide gets stored in macrophages (the scavenges cells of the body), which takes up characteristic appearance unique to those affected with this disorder (Gaucher Cells - basically termed as). These lipids get accumulated in the spleen, liver, bone marrow, brain and the lungs. Basically there are three types of ...
4,8-Sphingadienine and 4-hydroxy-8-sphingenine activate ceramide production in the skin | Lipids in Health and Disease | Full...
Although previous reports have demonstrated that dietary glucosylceramide can decrease TEWL from human skin [24], the mechanism was unclear. Ueda et al. reported that orally administrated ceramide was distributed to the dermis after intestinal absorption, followed by transfer from the dermis to the epidermis [25]. Ishikawa et al. also showed that dietary glucosylceramide was degraded into sphingoids, which were absorbed through the intestinal epithelial cells of rats and were subsequently also found in the lymph fluid in these rats [11]. Another study showed that 4-hydroxysphinganine could activate the PPARs [26] that are the key regulators of keratinocyte differentiation [27].. Keratinocyte differentiation is closely related to internal ceramide synthesis [28]. It is unlikely that orally ingested glucosylceramide would specifically localize to the skin because the amount of ingested glucosylceramide is simply too little to enhance ceramide levels in the skin. We hypothesized that sphingoids are ...

TY - JOUR. T1 - In vitro biosynthesis of sialosylgalactosylceramide (G7) by mouse brain microsomes. AU - Yu, R. K.. AU - Lee, S. H.. N1 - Copyright: Copyright 2004 Elsevier B.V., All rights reserved.. PY - 1976. Y1 - 1976. N2 - A sialyltransferase activity which catalyzes the synthesis of sialosylgalactosylceramide (G7) from added galactocerebroside and CMP N acetylneuraminic acid has been demonstrated in mouse brain microsomes. The enzyme reactions shows a pH optimum of 6.3 and requires detergents. Both Mn2+ and Ca2+ inhibited the reaction, whereas Mg2+ had no effect. The apparent Km for galactocerebroside leading to G7 was estimated to be 8.7 x 10-4 M. The same microsomal preparation also synthesized hematoside when ceramide lactoside was the glycolipid acceptor. The apparent Km for ceramide lactoside was about 1/10th that for galactocerebroside. When the preparations were partially inactivated by heat the synthesis of G7 and of hematoside was reduced at approximately the same rate. Liver ...
PLTP - Phospholipid transfer protein precursor - Homo sapiens (Human) - PLTP gene & protein
Facilitates the transfer of a spectrum of different lipid molecules, including diacylglycerol, phosphatidic acid, sphingomyelin, phosphatidylcholine, phosphatidylglycerol, cerebroside and phosphatidyl ethanolamine. Essential for the transfer of excess surface lipids from triglyceride-rich lipoproteins to HDL, thereby facilitating the formation of smaller lipoprotein remnants, contributing to the formation of LDL, and assisting in the maturation of HDL particles. PLTP also plays a key role in the uptake of cholesterol from peripheral cells and tissues that is subsequently transported to the liver for degradation and excretion. Two distinct forms of PLTP exist in plasma: an active form that can transfer PC from phospholipid vesicles to high-density lipoproteins (HDL), and an inactive form that lacks this capability.

The sphingosine kinase inhibitor N, N-dimethylsphingosine inhibits neointimal hyperplasia - Strathprints
Sphingosine-1-phosphate and its receptors may be involved in vascular smooth muscle cell (VSMC) proliferation following vascular injury. Here, we evaluate the effect of d-erythro-N,N-dimethylsphingosine (DMS), a sphingosine kinase (SK) inhibitor, on VSMC proliferation, apoptosis and neointimal formation. Growth responses in vitro to fetal calf serum (FCS) were measured by [3H]-thymidine incorporation and extracellular signal-regulated kinase-1/2 (ERK-1/2) activation in quiescent primary cultures of porcine VSMC in the presence and absence of various concentrations of the SK inhibitor DMS. In vivo treatment with DMS was delivered with a local endoluminal catheter, following balloon injury of coronary arteries. The artery intimal formation was investigated by angiography, myography and histomorphometry. In vitro experiments indicated that DMS induced a dose-dependent reduction in [3H]-thymidine incorporation and ERK-1/2 activation via a protein kinase C (PKC) independent mechanism with an IC50 ...
