In vivo (13)C MRS in the mouse brain at 14.1 Tesla and metabolic flux quantification under infusion of [1,6-(13)C2]glucose

Rolf Gruetter, Cristina Ramona Cudalbu, Bernard Lanz, Carole Poitry-Yamate, Marta Lai, Corina Mihaela Berset

In vivo (13)C magnetic resonance spectroscopy (MRS) enables the investigation of cerebral metabolic compartmentation while, e.g. infusing (13)C-labeled glucose. Metabolic flux analysis of (13)C turnover previously yielded quantitative information of glutam ...

In vivo cerebral metabolism of glioblastoma xenografts assessed with ¹H MRS, ¹³C MRS and ¹⁸F-FDG PET

Marta Lai

Magnetic resonance spectroscopy (MRS) is a powerful tool when studying metabolism in intact and living organs preserving cells in their natural microenvironment with minimal external interference. The unique insights offered by the observation of metabolic ...

Adenosine A(1) receptors control the metabolic recovery after hypoxia in rat hippocampal slices

João Miguel das Neves Duarte

Adenosine is a neuromodulator that protects neurons from hypoxia. This effect is attributed to the ability of adenosine A(1) receptors (A(1)R) to inhibit excitatory synaptic transmission. However, A(1)R activation also protects non-brain tissues from hypox ...

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 ...

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 ...

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 ...

Glutamatergic and GABAergic energy metabolism measured in the rat brain by 13C NMR spectroscopy at 14.1 T

Rolf Gruetter, João Miguel das Neves Duarte

Energy metabolism supports both inhibitory and excitatory neurotransmission processes. This study investigated the specific contribution of astrocytic metabolism to γ-aminobutyric acid (GABA) synthesis and inhibitory GABAergic neurotransmission that remain ...

Role of the Glyoxalase System in Astrocyte-Mediated Neuroprotection

Pierre Magistretti, Igor Allaman, Thierry Laroche, Jiangyan Yang, Jean-Marie Petit

The glyoxalase system is the most important pathway for the detoxification of methylglyoxal (MG), a highly reactive dicarbonyl compound mainly formed as a by-product of glycolysis. MG is a major precursor of advanced glycation end products (AGEs), which ar ...

Comment on recent modeling studies of astrocyte-neuron metabolic interactions

Pierre Magistretti, Igor Allaman, Renaud Jolivet, Luc Pellerin

Recent years have seen a surge in mathematical modeling of the various aspects of neuron-astrocyte interactions, and the field of brain energy metabolism is no exception in that regard. Despite the advent of biophysical models in the field, the long-lastin ...

Restoration of cognitive and motor functions by ciliary neurotrophic factor in a primate model of Huntington's disease

Patrick Aebischer, Nicole Déglon

Huntington's disease (HD) is an inherited disorder characterized by cognitive impairments, motor deficits, and progressive dementia. These symptoms result from progressive neurodegenerative changes mainly affecting the neostriatum. This pathology is fatal ...
