Oligodendrocytes myelinate axons for rapid impulse conduction and contribute to normal axonal functions in the central nervous system. In multiple sclerosis, demyelination is caused by autoimmune attacks, but the role of oligodendroglial cells in disease progression and axon degeneration is unclear. Here we show that oligodendrocytes harbor peroxisomes(More)
Disorders of neuronal migration in cerebral cortex are associated with neurological impairments, including mental retardation and epilepsy. Their causes and pathophysiology remain largely unknown, however. In patients with Zellweger disease, a lethal panperoxisomal disorder, and in mice lacking the Pxr1 import receptor for peroxisomal matrix proteins, the(More)
The Herschel ATLAS is the largest open-time key project that will be carried out on the Herschel Space Observatory. It will survey 510 square degrees of the extragalactic sky, four times larger than all the other Herschel surveys combined, in five far-infrared and submillimetre bands. We describe the survey, the complementary multi-wavelength datasets that(More)
Oxysterols and cholestenoic acids are oxidised forms of cholesterol with a host of biological functions. The possible roles of oxysterols in various neurological diseases makes the analysis of these metabolites in the central nervous system of particular interest. Here, we report the identification and quantification of a panel of twelve sterols in mouse(More)
Peroxisomal metabolism is essential for normal brain development both in men and in mice. Using conditional knock-out mice, we recently showed that peroxisome deficiency in liver has a severe and persistent impact on the formation of cortex and cerebellum, whereas absence of functional peroxisomes from the CNS only causes developmental delays without(More)
Defects in the formation of the cerebral cortex and the cerebellum are a prominent feature of the peroxisome biogenesis disorder Zellweger syndrome and in mouse models for this disease. The aim of the present study was to investigate the impact of liver and brain peroxisomes on neurodevelopment by analyzing mice with tissue-selective elimination of(More)
Ablation of functional peroxisomes from all neural cells in Nestin-Pex5 knockout mice caused remarkable neurological abnormalities including motoric and cognitive malfunctioning accompanied by demyelination, axonal degeneration, and gliosis. An oligodendrocyte selective Cnp-Pex5 knockout mouse model shows a similar pathology, but with later onset and slower(More)
The dynamics of dopamine (DA) action on PRL release was studied in superfused rat anterior pituitary cell aggregates, cultured for for 5 days either in conventional or in serum-free defined medium. In aggregates cultured in conventional medium 0.1-1 nM DA applied for 20 min provoked a rapid and concentration-dependent inhibition of PRL release, lasting only(More)
alpha-Synuclein (alphaS) is a presynaptic protein implicated in Parkinson's disease (PD). Growing evidence implicates mitochondrial dysfunction, oxidative stress, and alphaS-lipid interactions in the gradual accumulation of alphaS in pathogenic forms and its deposition in Lewy bodies, the pathological hallmark of PD and related synucleinopathies. The(More)
In superfused rat anterior pituitary cell reaggregates, cultured for 5 days in serum-free defined medium, vasoactive intestinal peptide (VIP) concentration-dependently stimulated prolactin (Prl) release but had only a marginal effect on growth hormone (GH) release. When reaggregates were cultured in the presence of 80 nM dexamethasone (Dex) VIP strongly(More)
