Metabolic gene expression changes in astrocytes in Multiple Sclerosis cerebral cortex are indicative of immune-mediated signaling

Pierre Magistretti, Igor Allaman

Emerging as an important correlate of neurological dysfunction in Multiple Sclerosis (MS), extended focal and diffuse gray matter abnormalities have been found and linked to clinical manifestations such as seizures, fatigue and cognitive dysfunction. To in ...

SOD1 silencing in motoneurons or glia rescues neuromuscular function in ALS mice

Patrick Aebischer, Bernard Schneider, Christopher Towne, Elisabeth Anne Dirren, Julianne Bobela, Cylia Cloé Rochat

Objective: Amyotrophic lateral sclerosis is an incurable disorder mainly characterized by motoneuron degeneration. Mutations in the superoxide dismutase 1 (SOD1) gene account for 20% of familial forms of the disease. Mutant SOD1 exerts multiple pathogenic ...

Brain energy metabolism measured by 13C magnetic resonance spectroscopy in vivo upon infusion of [3-13C]lactate

Rolf Gruetter, João Miguel das Neves Duarte, Freya-Merret Girault

The brain uses lactate produced by glycolysis as an energy source. How lactate originated from the blood stream is used to fuel brain metabolism is not clear. The current study measures brain metabolic fluxes and estimates the amount of pyruvate that becom ...

Control of Mitochondrial pH by Uncoupling Protein 4 in Astrocytes Promotes Neuronal Survival

Pierre Magistretti, Hélène Danielle Perreten Lambert, Sylvain Eric Lengacher, Manuel Raphael Zenger, Jean-Yves Chatton

Brain activity is energetically costly and requires a steady and highly regulated flow of energy equivalents between neural cells. It is believed that a substantial share of cerebral glucose, the major source of energy of the brain, will preferentially be ...

In vivo quantification of neuro-glial metabolism and glial glutamate concentration using 1H-[13C] MRS at 14.1T

Rolf Gruetter, Lijing Xin, Bernard Lanz

Astrocytes have recently become a major center of interest in neurochemistry with the discoveries on their major role in brain energy metabolism. An interesting way to probe this glial contribution is given by in vivo 13C NMR spectroscopy coupled with the ...

Connexin 30 sets synaptic strength by controlling astroglial synapse invasion

Graham Knott, Nicole Déglon

Astrocytes play active roles in brain physiology by dynamic interactions with neurons. Connexin 30, one of the two main astroglial gap-junction subunits, is thought to be involved in behavioral and basic cognitive processes. However, the underlying cellula ...

Astrocyte–neuron co-culture on microchips based on the model of SOD mutation to mimic ALS

Philippe Renaud, Pierre Magistretti, Patrick Aebischer, Sylvain Eric Lengacher, Anja Kunze, Elisabeth Anne Dirren

Amyotrophic lateral sclerosis (ALS) is the most common motor neuron disease. ALS is believed to be a non-cell autonomous condition, as other cell types, including astrocytes, have been implicated in disease pathogenesis. Hence, to facilitate the developmen ...

Regulation of Neurotrophic Factors and Energy Metabolism by Antidepressants in Astrocytes

Pierre Magistretti, Jean-Luc Martin, Igor Allaman

There is growing evidence that astrocytes are involved in the neuropathology of major depression. In particular, decreases in glial cell density observed in the cerebral cortex of individuals with major depressive disorder are accompanied by a reduction of ...
