Investigation of physiological roles of AMPK-activated protein kinase y3

Clinical trials have shown that direct activators of an evolutionary-conserved metabolic sensor, AMP-activated protein kinase (AMPK), are beneficial in preventing/treating a range of metabolic disorders, including type 2 diabetes. These activators, includi ...

Glycogen metabolism is impaired in the brain of male type 2 diabetic Goto‐Kakizaki rats

João Miguel das Neves Duarte, Ana Francisca Leal Silva Soares

Diabetes impacts the central nervous system predisposing to cognitive decline. While glucose is the main source of energy fueling the adult brain, brain glycogen is necessary for adequate neuronal function, synaptic plasticity and memory. In this study, we ...

Ultra high magnetic field for glial contribution into brain metabolism studied by MR spectroscopy and CEST methods for molecular imaging of glycogen

Elise Marie Catherine Vinckenbosch

Magnetic resonance at ultra-high field increases signal and spectral dispersion. In this thesis, I use those characteristics to investigate three different subjects in 13C spectroscopy, hyperpolarized methods and chemical exchange saturation transfer (CEST ...

Technical and experimental features of Magnetic Resonance Spectroscopy of brain glycogen metabolism

Rolf Gruetter, Hongxia Lei, Ana Francisca Leal Silva Soares

In the brain, glycogen is a source of glucose not only in emergency situations but also during normal brain activity. Altered brain glycogen metabolism is associated with energetic dysregulation in pathological conditions, such as diabetes or epilepsy. Bot ...

Glycogen Supercompensation in the Rat Brain After Acute Hypoglycemia is Independent of Glucose Levels During Recovery

Rolf Gruetter, João Miguel das Neves Duarte

Patients with diabetes display a progressive decay in the physiological counter-regulatory response to hypoglycemia, resulting in hypoglycemia unawareness. The mechanism through which the brain adapts to hypoglycemia may involve brain glycogen. We tested t ...

Functional analysis of Bicc1 and novel interacting proteins in renal tubule cell metabolism and polycystic kidneys

Lucía Carolina Leal Esteban

Genetic disorders known as ciliopathies develop polycystic kidneys, including autosomal dominant and autosomal recessive polycystic kidney diseases (ADPKD and ARPKD). Several signaling pathways including the cAMP/PKA pathway are implicated in driving cyst ...

Three-dimensional immersive virtual reality for studying cellular compartments in 3D models from EM preparations of neural tissues

Pierre Magistretti, Corrado Cali, Daniya Boges, Madhusudhanan Srinivasan

Advances in the application of electron microscopy (EM) to serial imaging are opening doors to new ways of analyzing cellular structure. New and improved algorithms and workflows for manual and semiautomated segmentation allow us to observe the spatial arr ...

AMP-activated protein kinase

Serge Thanh Son Ducommun

AMP-activated protein kinase (AMPK) is an evolutionally conserved key sensor of cellular energy status. Under conditions of cellular energy stress, AMPK is activated and will switch off anabolic processes that consume ATP, while activating catabolic proces ...

Glutamate Cysteine Ligase-Modulatory Subunit Knockout Mouse Shows Normal Insulin Sensitivity but Reduced Liver Glycogen Storage

Pierre Magistretti, Kim Do

Glutathione (GSH) deficits have been observed in several mental or degenerative illness, and so has the metabolic syndrome. The impact of a decreased glucose metabolism on the GSH system is well-known, but the effect of decreased GSH levels on the energy m ...

Regulation Of Neuron-Astrocyte Metabolic Coupling Across The Sleep-Wake Cycle

Pierre Magistretti, Jean-Marie Petit

Over the last thirty years, a growing number of studies showed that astrocytes play a pivotal role in the energy support to synapses. More precisely, astrocytes adjust energy production to neuronal energy needs through different mechanisms grouped under th ...
