Many drugs have been approved for relapsing forms of multiple sclerosis but are only partly effective, are injected, and are expensive. We aimed to investigate use of of oral simvastatin (80 mg) in 30 individuals with relapsing-remitting multiple sclerosis. The mean number of gadolinium-enhancing lesions at months 4, 5, and 6 of treatment was compared with(More)
Proinflammatory cytokines and inducible nitric oxide synthase (iNOS) are involved in the pathogenesis of experimental allergic encephalomyelitis (EAE), an animal model of multiple sclerosis (MS). We have previously reported that lovastatin (Pahan, K., Sheikh., F.G., Namboodiri, A. and Singh, I., Lovastatin and Phenylacetate inhibit the induction of nitric(More)
Statins are inhibitors of HMG-CoA reductase that have been recently recognized as anti-inflammatory and neuroprotective drugs. Herein, we investigated anti-excitotoxic and anti-seizure effects of statins by using kainic acid (KA)-rat seizure model, an animal model for temporal lobe epilepsy and excitotoxic neurodegeneration. We observed that pre-treatment(More)
Mononuclear cell infiltration into the CNS and induction of inflammatory cytokines and iNOS in diseases like multiple sclerosis (MS) and experimental allergic encephalomyelitis (EAE) have been implicated in subsequent disease pathogenesis and progression. We report that Lovastatin treatment blocks the clinical disease and induction of inflammatory cytokines(More)
Inducible nitric oxide synthase (iNOS) is one of three NOS isoforms generating nitric oxide (NO) by the conversion of l-arginine to l-citrulline. iNOS has been found to be a major contributor to initiation/exacerbation of the central nervous system (CNS) inflammatory/degenerative conditions through the production of excessive NO which generates reactive(More)
X-adrenoleukodystrophy (X-ALD) is a complex disease where inactivation of ABCD1 gene results in clinically diverse phenotypes, the fatal disorder of cerebral ALD (cALD) or a milder disorder of adrenomyeloneuropathy (AMN). Loss of ABCD1 function results in defective beta oxidation of very long chain fatty acids (VLCFA) resulting in excessive accumulation of(More)
Globoid cell leukodystrophy (Krabbe disease) is an inherited neurological disorder caused by the pathogenomic accumulation of psychosine (galactosylsphingosine), a substrate for the deficient enzyme galactocerebroside beta-galactosidase. This study underscores the mechanism of action of psychosine in the regulation of oligodendrocyte cell death via the(More)
This study was designed to understand the role of inflammatory mediators involved in the neurobiology of childhood adrenoleukodystrophy (cALD) by comparing the differential expression of the inflammatory mediators with metabolite very long chain fatty acids that accumulate in this disease. Histopathological examinations indicated extensive demyelination and(More)
AMP-activated-protein-kinase (AMPK) is a key sensor and regulator of cellular and whole-body energy metabolism and plays a key role in regulation of lipid metabolism. Since lipid metabolism has been implicated in neuronal amyloid-beta (Abeta) homeostasis and onset of Alzheimer's disease, we investigated the involvement of AMPK in neuronal lipid metabolism(More)
