SCALCO, F.B.; GIUGLIANI, R.; TOBO, P. and COELHO, J.C.. Effect of dimethylsulfoxide on sphingomyelinase activity and cholesterol metabolism in Niemann-Pick type C fibroblasts. Braz J Med Biol Res [online]. 1999, vol.32, n.1, pp.23-28. ISSN 1414-431X. http://dx.doi.org/10.1590/S0100-879X1999000100003.. Niemann-Pick type C (NPC) fibroblasts present a large concentration of cholesterol in their cytoplasm due to a still unidentified deficiency in cholesterol metabolism. The influence of dimethylsulfoxide (DMSO) on the amount of intracellular cholesterol was measured in 8 cultures of normal fibroblasts and in 7 fibroblast cultures from NPC patients. DMSO was added to the fibroblast cultures at three different concentrations (1, 2 and 4%, v/v) and the cultures were incubated for 24 h. Sphingomyelinase activity was significantly increased in both groups of cells only when incubated with 2% DMSO (59.4 ± 9.1 and 77.0 ± 9.1 nmol h-1 mg protein-1, controls without and with 2% DMSO, respectively; 47.7 ± ...

Patients with Niemann-Pick disease type C1 (NPC1), a lysosomal lipid storage disorder that causes neurodegeneration and liver damage, can present with IBD, but neither the significance nor the functional mechanism of this association is clear. We studied bacterial handling and antibacterial autophagy in patients with NPC1.We characterised intestinal inflammation in 14 patients with NPC1 who developed IBD. We investigated bacterial handling and cytokine production of NPC1 monocytes or macrophages in vitro and compared NPC1-associated functional defects to those caused by IBD-associated nucleotide-binding oligomerization domain-containing protein 2 (NOD2) variants or mutations in X-linked inhibitor of apoptosis (XIAP).Patients with the lysosomal lipid storage disorder NPC1 have increased susceptibility to early-onset fistulising colitis with granuloma formation, reminiscent of Crohns disease (CD). Mutations in NPC1 cause impaired autophagy due to defective autophagosome function that abolishes NOD2

Protein which, if defective, causes Niemann-Pick disease. Niemann-Pick disease comprises an inherited group of congenital lipidoses in which sphingolipids accumulate in cells, especially in the reticuloendothelial system, due to defective lysosomal storage. The disease is clinically characterized by progressive degeneration of the central nervous system with visceral accumulation of cholesterol and sphingomyelin. The clinical phenotype is highly variable and different types are distinguished by age of onset, degree of central nervous system involvement and by the amount of sphingomyelin phosphodiesterase activity ...

The paper by Yu et al. reports a strategy for modulating cellular proteostasis and restore functional activity of NPC1 in primary fibroblasts of patients with Niemannâ€Pick type C disease. The authors of this paper found that ryanodine receptor (RyR) antagonists increased steady-state NPC1 levels in fibroblasts carrying the p.I1061T mutation, which is degraded by the proteasome. These compounds also promoted trafficking of mutant NPC1 to late endosomes and lysosomes and rescued the aberrant storage of cholesterol and sphingolipids that is characteristic of disease. This study highlights the efficacy and the therapeutic potential of proteostasis regulators to recover function of NPC1 mutated proteins..

Niemann-Pick disease type C (NPC) is a lipid storage disease that can present in infants, children, or adults. Neonates can present with ascites and severe liver disease from infiltration of the liver and/or respiratory failure from infiltration of the lungs. Other infants, without liver or pulmonary disease, have hypotonia and developmental delay. The classic presentation occurs in mid-to-late childhood with the insidious onset of ataxia, vertical supranuclear gaze palsy (VSGP), and dementia. Dystonia and seizures are common. Dysarthria and dysphagia eventually become disabling, making oral feeding impossible; death usually occurs in the late second or third decade from aspiration pneumonia. Adults are more likely to present with dementia or psychiatric symptoms. The diagnosis of NPC is confirmed by biochemical testing that demonstrates impaired cholesterol esterification and positive fillipin staining in cultured fibroblasts. Biochemical testing for carrier status is unreliable. Most ...

Niemann-Pick disease C1 (NPC1) [MIM:257220]: A lysosomal storage disorder that affects the viscera and the central nervous system. It is due to defective intracellular processing and transport of low-density lipoprotein derived cholesterol. It causes accumulation of cholesterol in lysosomes, with delayed induction of cholesterol homeostatic reactions. Niemann-Pick disease type C1 has a highly variable clinical phenotype. Clinical features include variable hepatosplenomegaly and severe progressive neurological dysfunction such as ataxia, dystonia and dementia. The age of onset can vary from infancy to late adulthood. An allelic variant of Niemann-Pick disease type C1 is found in people with Nova Scotia ancestry.

In this case series, we demonstrate that Ursodeoxycholic acid (UDCA) improves liver dysfunction in Niemann-Pick type C (NPC) and may restore a suppressed cytochrome p450 system. NPC disease is a progressive neurodegenerative lysosomal storage disease caused by mutations in either the NPC1 or NPC2 genes. Liver disease is a common feature presenting either acutely as cholestatic jaundice in the neonatal period, or in later life as elevated liver enzymes indicative of liver dysfunction. Recently, an imbalance in bile acid synthesis in a mouse model of NPC disease was linked to suppression of the P450 detoxification system and was corrected by UDCA treatment. UDCA (3α, 7β-dihydroxy-5β-cholanic acid), a hydrophilic bile acid, is used to treat various cholestatic disorders. In this report we summarise the findings from four independent cases of NPC, three with abnormal liver enzyme levels at baseline, that were subsequently treated with UDCA. The patients differed in age and clinical features, they all

Niemann-Pick Type C (NPC) disease is an autosomal, recessive, neurovisceral disorder associated with defects in cholesterol and glycolipid trafficking and metabolism, leading to the accumulation of cholesterol in the late endosomes and lysosomes. This leads to organ enlargement, progressive neurodegeneration, and premature death. There is little known about the link between the alterations in cholesterol in NPC disease and neuronal dysfunction, and currently there is no effective therapy for this disorder. To gain insight to the effects of NPC disease on neurons of the central nervous system, I have examined aspects of neuronal function altered by cholesterol, and potentially NPC disease, including neurotrophin sensitivity and the development of synaptic interactions in neurons of the central nervous system. In addition, I have assessed the in vivo effect of injecting an adenovirus expressing an NPC1-GFP fusion gene into the cerebellum, a major target of NPC disease, in an attempt to explore the ...

Myoclonus can be present, but its value in early diagnosis and the evolving clinical phenotype in NP-C is unclear. In this paper we present eight Dutch cases of NP-C of whom five with myoclonus. Methods: Eight patients with genetically confirmed NP-C were recruited from two Dutch University Medical Centers. A structured interview and neuropsychological tests (for working and verbal memory, attention and emotion recognition) were performed. Movement disorders were assessed using a standardized video protocol. Quality of life was evaluated by questionnaires (Rand-36, SIP-68, HAQ). In four ...

Scientists tested tissue samples in the metabolomics facility of the Diabetic Cardiovascular Disease Center. In NPC patients, two oxidized forms of cholesterol were present at levels nine to 10 times higher than normal. The same markers were not elevated in healthy children and adults or in persons with elevated cholesterol levels, heart disease, diabetes or other forms of lysosomal storage disorders.. These markers have all the characteristics we wanted for a clinical test, and were now working to develop it into a clinical assay, Ory says. We want to make the possibility of testing for NPC much easier for physicians to consider if they see the slightest hints that it might be present.. Given the potential advantages that presymptomatic treatment of NPC may offer, including improved quality of life and extended lifespan, Ory also hopes to get people thinking about the possibility of adding NPC to the recommended neonatal screenings.. Were not sure we fully appreciate the impact of this ...

NPC is a devastating neurodegenerative disorder for which there is only one treatment licensed. The heat-shock response (HSR) is a key cellular process enabling the cell to cope with a wide variety of pathological stressors. Induction of the HSR and the HSP70 protein family, have been shown to be protective in several neurodegenerative diseases, including LSDs. Orphazyme is currently investigating two approaches for treatment; recombinant HSP70 and Arimoclomol, a small molecule which enhances the HSR and up-regulates HSP70. Both treatments have shown significant benefits on disease progression in a mouse model of NPC1 disease, but greater understanding of their mechanisms of action is needed to fully optimise treatment of this disease and to identify further therapeutic targets and biomarkers for clinical trials. The HSR plays a role in a variety of cellular processes, e.g. refolding of damaged proteins and degradation of protein aggregates. HSP70 has also been shown to prevent lysosomal ...

Caspase-1 and IL-1β have been postulated to have deleterious effects for the host in acute P. aeruginosa-infections. Schultz et al. found that IL-1R deficiency had a protective effect in response to pulmonary infection with P. aeruginosa (36). In another study, neutralization of IL-1β with antibodies protected acid sphingomyelinase-deficient mice from lethal P. aeruginosa pneumonia (37). In addition, Thakur et al. found in a P. aeruginosa keratitis model, that caspase-1 deficiency results in less corneal damage (38). However, it remains unclear from these studies if the adverse effects mediated by IL-1β and caspase-1 are caused by inflammatory damage or lack of control of bacterial replication. In contrast to these studies, IL-1R-deficient mice had greater colonization with P. aeruginosa compared with WT mice after oral exposure to the pathogen in drinking water (39). We show that the IPAF-inflammasome plays an important role in host defenses against P. aeruginosa. IPAF-deficiency resulted in ...

The rare lysosomal storage disorder Niemann-Pick disease type C1 (NPC1) arises from mutation of NPC1, which encodes a lysosomal transmembrane protein essential for normal transport and trafficking of cholesterol and sphingolipids. NPC1 is highly heterogeneous in both clinical phenotypes and age of onset. Previous studies have reported sub-Mendelian survival rates for mice homozygous for various Npc1 mutant alleles but have not studied the potential mechanisms underlying this phenotype. We performed the first developmental analysis of a Npc1 mouse model, Npc1em1Pav, and discovered significant fetal growth restriction in homozygous mutants beginning at E16.5. Npc1em1Pav/em1Pav mice also exhibited cyanosis, increased respiratory effort, and over 50% lethality at birth. Analysis of neonatal lung tissues revealed lipid accumulation, notable abnormalities in surfactant, and enlarged alveolar macrophages, suggesting that lung abnormalities may be associated with neonatal lethality in Npc1em1Pav/em1Pav mice.

In 2010, the National Institutes of Health (NIH) established the Therapeutics for Rare and Neglected Diseases (TRND) program within the National Center for Advancing Translational Sciences (NCATS), which was created to stimulate drug discovery and development for rare and neglected tropical diseases through a collaborative model between the NIH, academic scientists, nonprofit organizations, and pharmaceutical and biotechnology companies. This paper describes one of the first TRND programs, the development of 2-hydroxypropyl-β-cyclodextrin (HP-β-CD) for the treatment of Niemann-Pick disease type C1 (NPC1). NPC is a neurodegenerative, autosomal recessive rare disease caused by a mutation in either the NPC1 (about 95% of cases) or the NPC2 gene (about 5% of cases). These mutations affect the intracellular trafficking of cholesterol and other lipids, which leads to a progressive accumulation of unesterified cholesterol and glycosphingolipids in the CNS and visceral organs. Affected individuals ...

Copper dyshomeostasis has been identified as a pathological feature of Alzheimers disease (AD) and Niemann-Pick disease type C1 (NPC1), as well as other neurological disorders. However, the nature of copper dysregulation in these conditions as well as its impact on disease severity and progression remain poorly understood. The growing availability of high-resolution Positron Emission Tomography (PET) systems and copper radionuclides encourages the use of copper radiotracers to measure copper fluxes in a variety of disease states with PET imaging. In this thesis, we investigated copper trafficking at brain and whole-body levels with 64Cu-PET in preclinical models of AD and NPC1 disease. The blood-brain barrier-permeable copper-64 bis(thiosemicarbazone) complex 64Cu-GTSM was used to monitor the retention, efflux and redistribution of radiocopper within the brain, while 64Cu-acetate was used to visualise copper uptake into organs from blood plasma. In addition to these imaging studies, a new ...

NPD type A appears during infancy and is characterized by an enlarged liver and spleen failure to gain weight and grow at the expected rate (failure to thrive), and gradual deterioration of the nervous system. NP-A is also known as the neurological type, due to the involvement of the nervous system. Children affected by this condition generally do not survive past early childhood. There is no treatment for NP-A.. NPD type B has a range of symptoms that may include enlargement of the liver and spleen, growth delays, and problems with lung function including frequent lung infections. Other signs include blood abnormalities such as elevated levels of cholesterol and other lipids (fats), and decreased numbers of blood cells involved in clotting (platelets). Most patients with NP-B develop symptoms when they are children, although some have milder disease and are not diagnosed until they are adults. NP-B is known as the non-neurological type because the brain is not usually affected.. Is there ...

Understanding disease pathology and developing treatments in rare and neglected diseases.. Our goal is to convert research findings into therapeutics in rare, inherited disorders as well as neglected infectious diseases. These diseases have generally been ignored by the pharmaceutical industry because the financial rewards for developing new drugs and vaccines to treat them are so insignificant. In rare diseases we focus on lysosomal disorders such as Niemann Pick Type C (NP-C) and Mucopolysaccharidosis Type III A (MPS IIIA), that result in neurodegenerative disease.. We have developed a quantitative, rapid neurobehavioural score by which to measure NP-C disease in mice. Using this scale, we are able to identify unique genetic signatures associated with disease progression, develop biomarkers as well as screen for drugs to treat disease in mice, in order that drugs can be progressed to clinical trials and therapeutic utilization. Parallel studies are underway with MPS IIIA. We also study how ...

Niemann-Pick disease (NPD) is a lipid storage disorder that results from the deficiency of a lysosomal enzyme, acid sphingomyelinase. The original description of NPD referred to what is currently termed NPD type A, which is a fatal disorder of early childhood characterized by failure to thrive, hepatosplenomegaly, and a rapidly progressive ne...

Cyclodextrin therapy for NPC disease was first evaluated in 2001 when it was found that intraperitoneal HPβCD (500 mg/kg given three times per week) lowered liver unesterified cholesterol and delayed the onset of continuous extensor tremor of the limbs in Npc1−/− mice (26). In a subsequent study, a single dose of SC-administered allopregnanolone (25 mg/kg) dissolved in a 20% HPβCD solution (4000 mg/kg) increased Purkinje cell and granule cell survival, reduced brain ganglioside accumulation, and nearly doubled the life span of Npc1−/− mice (43). Although the substantial positive effects were attributed to the reconstitution of allopregnanolone in the Npc1−/− mouse brain (43), follow-up studies by two laboratories independently found that HPβCD (4000 mg/kg SC) alone was sufficient to reduce storage of cholesterol and gangliosides and to positively affect NPC-related neurological disease (30, 31, 44). Our data in the feline model support evidence of a dose-related effect of SC ...

Background: Niemann-Pick C1 like 1 Protein (NPC1L1), a target protein of ezetimibe, is expressed not only in the small intestine but also in the liver of humans, while its expression in the liver of mice has been shown to be little. To elucidate the role of hepatic NPC1L1 expression on lipoprotein and glucose metabolism, we over-expressed NPC1L1 in mice liver utilizing adenoviral gene transfer.. Methods & Results: C57BL/6 mice, fed on normal chow with or without ezetimibe for 4 weeks, were injected with NPC1L1 adenovirus (L1-mice) or control virus (C-mice). Four and 5 days after injection, we analyzed glucose metabolism and plasma lipid profiles, respectively. The plasma cholesterol levels increased in L1-mice (C-mice 96 mg/dl vs L1-mice 155 mg/dl); the FPLC profile of pooled plasma revealed increased cholesterol contents in the LDL-sized and large HDL-sized lipoprotein fractions. The large HDL fractions, which showed α-mobility on agarose electrophoresis, were rich in apoE and free cholesterol ...

The selection of Vα14 NKT cells in the thymus is dependent on the expression of iGb3-CD1d complexes by cortical thymocytes. Presentation of the endogenous iGb3 by CD1d molecules requires the presence of iGb3 in the lysosomes and its assisted loading into CD1d by LTPs. We previously showed that the impaired production of iGb3 or the lack of saposins resulted in the severe deficiency or lack of Vα14 NKT cells (10, 21). In an attempt to find other lysosomal LTPs involved in the loading of lipid antigens into CD1d, we investigated whether NPC2 could play a role in Vα14 NKT cell selection and lipid antigen presentation.. Our study establishes that a deficiency in NPC2 profoundly affects the numbers of Vα14 NKT cells in the thymus and peripheral tissues. It is important to notice that this phenotype was observed in mice and cells that have some residual NPC2 activity (27) and that a complete knockout of expression would likely reinforce the traits that we observed. The thymic phenotype reveals two ...

Eye movement abnormalities in familial mental retardation syndrome should lead to the suspicion of a storage disorder, including Niemann Pick disease type C, Gauchers disease, abetalipoproteinemia and Wilsons disease. The eye movement abnormalities in our two patients were suggestive of Niemann Pick disease type C, characterized by initial loss of voluntary vertical eye movements and subsequent loss of horizontal eye movements, with preservation of the vestibulo-ocular response. The characteristics of eye movements in storage disorders are different. In Gauchers disease a progressive horizontal gaze palsy, in abetalipoproteinemia a particular type of internuclear ophthalmoplegia with nystagmus of the adducting eye and in Wilsons disease slowing of saccades may be observed ...

BACKGROUND: The parasitic flatworm Clonorchis sinensis inhabits the biliary tree of humans and other piscivorous mammals. This parasite can survive and thrive in the bile duct, despite exposure to bile constituents and host immune attack. Although the precise biological mechanisms underlying this adaptation are unknown, previous work indicated that Niemann-pick type C2 (NPC2)-like sterol-binding proteins might be integral in the host-parasite interplay. Expansions of this family in some invertebrates, such as arthropods, have shown functional diversification, including novel forms of chemoreception. Thus, here we curated the NPC2-like protein gene complement in C. sinensis, and predicted their conserved and/or divergent functional roles. METHODS: We used an established comparative genomic-bioinformatic approach to curate NPC2-like proteins encoded in published genomes of Korean and Chinese isolates of C. sinensis. Protein sequence and structural homology, presence of conserved domains and ...

Chief Technologist: Éva Kálmánchey Gombos. TThe Molecular Pathology division of the department was established in 1995. At the beginning the DNA analysis panel of severe inherited disorders was introduced, which was extended with the analysis of different genetic risk factors and pharmacogenetic testing. The division provides genetic testing in three main areas:. 1. Molecular genetic analysis of severe inherited diseases (cystic fibrosis, Duchenne/Becker muscular dystrophy, hemochromatosis, Smith-Lemli-Opitz syndrome, Niemann-Pick disease type C, autosomal recessive polycystic kidney disease, MODY, neonatal diabetes, etc).. 2. Molecular genetic analysis of inherited risk factors predisposing to different multifactorial diseases (thrombosis risk factors, hyperlipidemic risk factors).. 3. Pharmacogenetic testing (CYP2C9, TPMT, UGT1A1, VKORC1). In the routine diagnostic procedures a number of different methods are used (blotting techniques, allele-specific PCR, fluorescent real-time PCR methods, ...

Niemann-Pick type C disease (NP-C) is a fatal neurodegenerative disorder caused by a deficiency of NPC1 gene function, which leads to severe neuroinflammation such as astrogliosis. While reports demonstrating neuroinflammation are prevalent in NP-C, information about the onset and progression of cerebellar astrogliosis in this disorder is lacking. Using gene targeting, we generated vascular endothelial growth factor (VEGF) conditional null mutant mice. Deletion of VEGF in cerebellar Purkinje neurons (PNs) led to a significant increase of astrogliosis in the brain of NP-C mice in addition to the loss of PNs, suggesting PN-derived VEGF as an important factor in NP-C pathology ...

8. The mevalonate pathway. of LDL receptors, internalization of the receptor or changes in enzymes involved in synthesis, and cholesterol efflux via lipoproteins. Niemann-Pick Type C disease is characterized by substantial intracellular accumulation of unesterified cholesterol. Binding, internalization and lysosomal hydrolysis of LDL is normal. Cholesterol esterification, however, is not stimulated, and there is a lag in down regulation of the receptor and cellular cholesterol synthesis. A defect in intracellular transport of LDL derived cholesterol has been proposed [247]. O. Ratios above this have been related to a number of disease states as well as being found in human aging systems. The causes of such a change in relative amounts of cholesterol and PL may be due to alterations in cholesterol exchange with the environment, changes in the relative rates of turnover of cholesterol and lipids or changes in the activities of the proteins involved in the coordination of their metabolism. Cornell ...

Förster resonance energy transfer (FRET) -based techniques have recently been applied to study the interactions between β-site APP-cleaving enzyme-GFP (BACE1-GFP) and amyloid precursor protein-mRFP (APP-mRFP) in U373 glioblastoma cells. In this context, the role of APP-BACE1 proximity in Alzheimers disease (AD) pathogenesis has been discussed. FRET was found to depend on intracellular cholesterol levels and associated alterations in membrane stiffness. Here, NPC1 null cells (CHO-NPC1−/−), exhibiting increased cholesterol levels and disturbed cholesterol transport similar to that observed in Niemann-Pick type C disease (NPC), were used to analyze the influence of altered cholesterol levels on APP-BACE1 proximity. Fluorescence lifetime measurements of whole CHO-wild type (WT) and CHO-NPC1−/− cells (EPI-illumination microscopy), as well as their plasma membranes (total internal reflection fluorescence microscopy, TIRFM), were performed. Additionally, generalized polarization (GP) measurements of

Cholesterol (Chol) is a crucial component of cellular membranes, but knowledge of its intracellular dynamics is scarce. Thus, it is of utmost interest to develop tools for visualization of Chol organization and dynamics in cells and tissues. For this purpose, many studies make use of fluorescently labeled Chol analogs. Unfortunately, the introduction of the label may influence the characteristics of the analog, such as its localization, interaction, and trafficking in cells; hence, it is important to get knowledge of such bias. In this report, we compared different fluorescent lipid analogs for their performance in cellular assays: 1) plasma membrane incorporation, specifically the preference for more ordered membrane environments in phase-separated giant unilamellar vesicles and giant plasma membrane vesicles; 2) cellular trafficking, specifically subcellular localization in Niemann-Pick type C disease cells; and 3) applicability in fluorescence correlation spectroscopy (FCS)-based and super-resolution

Lysosomal storage diseases (LSDs; /ˌlaɪsəˈsoʊməl/) are a group of about 50 rare inherited metabolic disorders that result from defects in lysosomal function. Lysosomes are sacs of enzymes within cells that digest large molecules and pass the fragments on to other parts of the cell for recycling. This process requires several critical enzymes. If one of these enzymes is defective, because of a mutation, the large molecules accumulate within the cell, eventually killing it. Lysosomal storage disorders are caused by lysosomal dysfunction usually as a consequence of deficiency of a single enzyme required for the metabolism of lipids, glycoproteins (sugar-containing proteins), or so-called mucopolysaccharides. Individually, LSDs occur with incidences of less than 1:100,000; however, as a group, the incidence is about 1:5,000 - 1:10,000. Most of these disorders are autosomal recessively inherited such as Niemann-Pick disease, type C, but a few are X-linked recessively inherited, such as Fabry ...

Miglustat (OGT 918, N-butyl-deoxynojirimycin) is a drug developed by Oxford GlycoSciences and marketed by Actelion and is used primarily to treat type I Gaucher disease (GD1). It is marketed under the trade name Zavesca. Miglustat is used to treat adults with mild-to-moderate type I Gaucher disease for whom enzyme replacement therapy is unsuitable. It was approved in Europe in 2002 and by the US FDA in 2003. Miglustat is the first treatment to be approved for treating progressive neurological complications in people with Niemann-Pick disease, type C (NPC); it has been approved in Europe in 2009, Canada in 2010, and Japan in 2012, but not in the US where the FDA declined to approve it in 2010 and called for more data. Miglustat is contraindicated for people with neurological conditions, kidney problems, women who are pregnant, and men and women planning to conceive a child. Serious side effects include pain, burning, numbness or tingling in the hands, arms, legs, or feet; shaking hands that ...

One of a series of posts honoring ‪#RareDiseaseDay (Feb 28, 2015).. Historically, the starting point for making a rare disease diagnosis is the patients clinical profile: the set of symptoms and features that together define Diamond Blackfan anemia (DBA), Niemann-Pick disease or any of a thousand other conditions.. For example, anemia and problems absorbing nutrients are features of Pearson marrow pancreas syndrome (PS), whereas oddly shaped fingernails, lacy patterns on the skin and a proneness to cancer point to dyskeratosis congenita (DC).. The resulting diagnoses give the child and family an entry point into a disease community, and is their anchor for understanding whats happening to them and others: Yes, my child has that and heres how it affects her. Does it affect your child this way too?. But as researchers probe the relationships between genes and their outward expression-between genotype and phenotype-some families are losing that anchor. They may discover that their child ...

the sphingolipid mutations look like IQ boosters. The key datum is the effect of increased levels of the storage compounds. Glucosylceramide, the Gaucher storage compound, promotes axonal growth and branching (Schwartz et al., 1995). In vitro, decreased glucosylceramide results in stunted neurones with short axons while an increase over normal levels (caused by chemically inhibiting glucocerebrosidase) increases axon length and branching. There is a similar effect in Tay-Sachs (Walkley et al., 2000; Walkley, 2003): decreased levels of GM2 ganglioside inhibit dendrite growth, while an increase over normal levels causes a marked increase in dendritogenesis. This increased dendritogenesis also occurs in Niemann-Pick type A cells, and in animal models of Tay-Sachs and Niemann-Pick. (Cochran et al., 2006 ...
