Fast in vivo assay of creatine kinase activity in the human brain by P-31 magnetic resonance fingerprinting

Lijing Xin, Mark Stephan Widmaier, Songi Lim, Daniel Wenz

A new and efficient magnetisation transfer P-31 magnetic resonance fingerprinting (MT-P-31-MRF) approach is introduced to measure the creatine kinase metabolic rate kCK

Metabolic, cellular and defense responses to single and co-exposure to carbamazepine and methylmercury in Dreissena polymorpha

Florian Frédéric Vincent Breider, Dominique Grandjean

Carbamazepine (CBZ) and Hg are widespread and persistent micropollutants in aquatic environments. Both pollutants are known to trigger similar toxicity mechanisms, e.g. reactive oxygen species (ROS) production. Here, their effects were assessed in the zebr ...

Abnormal brain oxygen homeostasis in an animal model of liver disease

Cristina Ramona Cudalbu Moldovan, Dunja Simicic, Katarzyna Pierzchala

Background & Aims: Increased plasma ammonia concentration and consequent disruption of brain energy metabolism could underpin the pathogenesis of hepatic encephalopathy (HE). Brain energy homeostasis relies on effective maintenance of brain oxygenation, an ...

Radical-free hyperpolarized MRI using endogenously occurring pyruvate analogues and UV-induced nonpersistent radicals

Rolf Gruetter, Josefina Adriana Maria Bastiaansen, Hikari Ananda Infinity Yoshihara, Andrea Capozzi, Alice Radaelli, Claudia Christina Zanella

It was recently demonstrated that nonpersistent radicals can be generated in frozen solutions of metabolites such as pyruvate by irradiation with UV light, enabling radical-free dissolution dynamic nuclear polarization. Although pyruvate is endogenous, the ...

Brain NAD Is Associated With ATP Energy Production and Membrane Phospholipid Turnover in Humans

Rolf Gruetter, Lijing Xin, Özlem Ipek, Maya Shevlyakova

The brain requires a large amount of energy, mostly derived from the metabolism of glucose, which decreases substantially with age and neurological diseases. While mounting evidence in model organisms illustrates the central role of brain nicotinamide aden ...

Pyruvate cellular uptake and enzymatic conversion probed by dissolution DNP-NMR: the impact of overexpressed membrane transporters

Arnaud Comment, Paul Romeo Vasos, Riccardo Balzan

Pyruvate membrane crossing and its lactate dehydrogenase-mediated conversion to lactate in cells featuring different levels of expression of membrane monocarboxylate transporters (MCT4) were probed by dissolution dynamic nuclear polarization-enhanced NMR. ...

A Cellular Perspective on Brain Energy Metabolism and Functional Imaging

Pierre Magistretti, Igor Allaman

The energy demands of the brain are high: they account for at least 20% of the body's energy consumption. Evolutionary studies indicate that the emergence of higher cognitive functions in humans is associated with an increased glucose utilization and expre ...

Mitochondrial function in the brain links anxiety with social subordination

Maria del Carmen Sandi Perez, Carlos Canto Alvarez, Olivia Zanoletti, Fiona Hollis, Laura Lozano Montes

Dominance hierarchies are integral aspects of social groups, yet whether personality traits may predispose individuals to a particular rank remains unclear. Here we show that trait anxiety directly influences social dominance in male outbred rats and ident ...

Genes Involved in the Astrocyte-Neuron Lactate Shuttle (ANLS) Are Specifically Regulated in Cortical Astrocytes Following Sleep Deprivation in Mice

Pierre Magistretti, Sophie Burlet Godinot

Study Objectives: There is growing evidence indicating that in order to meet the neuronal energy demands, astrocytes provide lactate as an energy substrate for neurons through a mechanism called "astrocyte-neuron lactate shuttle" (ANLS). Since neuronal act ...

Lactate metabolism shift in CHO cell culture: the role of mitochondrial oxidative activity

Florian Maria Wurm, Martin Jordan, Mathieu Benjamin Stettler

Lactate production is monitored in industrial processes as a crucial metabolite for cultured mammalian cells. Typically lactate is strongly produced during the exponential growth phase, while its net consumption is frequently observed when cells enter into ...

Metabolic Flux and Compartmentation Analysis in the Brain In vivo

João Miguel das Neves Duarte, Rolf Gruetter, Bernard Lanz

Through significant developments and progresses in the last two decades, in vivo localized nuclear magnetic resonance spectroscopy (MRS) became a method of choice to probe brain metabolic pathways in a non-invasive way. Beside the measurement of the total ...

Differential effects of pro- and anti-inflammatory cytokines alone or in combinations on the metabolic profile of astrocytes

Pierre Magistretti, Igor Allaman

We have previously reported that the pro-inflammatory cytokines tumor necrosis factor-α (TNFα) and interleukin-1β (IL-1β) induce profound modifications of the metabolic profile of astrocytes. The present study was undertaken to further characterize the eff ...

Stimulation-induced increases of astrocytic oxidative metabolism in rats and humans investigated with 1-11C-acetate

Pierre Magistretti

The purpose of this study was to investigate astrocytic oxidative metabolism using 1-(11)C-acetate. 1-(11)C-acetate kinetics were evaluated in the rat somatosensory cortex using a beta-scintillator during different manipulations (test-retest, infraorbital ...

Brain lactate kinetics: Modeling evidence for neuronal lactate uptake upon activation

Pierre Magistretti

A critical issue in brain energy metabolism is whether lactate produced within the brain by astrocytes is taken up and metabolized by neurons upon activation. Although there is ample evidence that neurons can efficiently use lactate as an energy substrate, ...
