Astrocytic and neuronal oxidative metabolism are coupled to the rate of glutamate-glutamine cycle in the tree shrew visual cortex

Rolf Gruetter, Nathalie Just, Sarah Catherine Sonnay, Gregor Rainer, João Miguel das Neves Duarte, Anne Catherine Clerc

Astrocytes play an important role in glutamatergic neurotransmission, namely by clearing synaptic glutamate and converting it into glutamine that is transferred back to neurons. The rate of this glutamate–glutamine cycle (VNT) has been proposed to couple t ...

Stress, glucocorticoid receptor and social behaviors

Peripuberty, comprising childhood and adolescence, constitutes an important time window in the brain development and maturation. Exposure to prolonged stress during this period has been shown to increase the risk for the development of psychopathologies la ...

MRS studies of neuroenergetics and glutamate/glutamine exchange in rats: Extensions to hyperammonemic models

Cristina Ramona Cudalbu, Bernard Lanz, Veronika Rackayová

In vivo Magnetic Resonance Spectroscopy is a useful tool to characterize brain biochemistry as well as its alteration in a large number of major central nervous system diseases. The present review will focus on the study of the glutamate-glutamine cycle, a ...

Neuronal Depolarization Drives Increased Dopamine Synaptic Vesicle Loading via VGLUT

Brian Donal McCabe

The ability of presynaptic dopamine terminals to tune neurotransmitter release to meet the demands of neuronal activity is critical to neurotransmission. Although vesicle content has been assumed to be static, in vitro data increasingly suggest that cell a ...

Layer-Dependent Short-Term Synaptic Plasticity Between Excitatory Neurons in the C2 Barrel Column of Mouse Primary Somatosensory Cortex

Carl Petersen, Sandrine Lefort

Neurons process information through spatiotemporal integration of synaptic input. Synaptic transmission between any given pair of neurons is typically a dynamic process with presynaptic action potentials (APs) evoking depressing or facilitating postsynapti ...

Physiological regulation of the CDK16/PCTAIRE-1 protein kinase and its proposed role in the brain

Saifeldin Nasser Mohamed Ibrahim Shehata

Cell signalling, mediated to a large extent by protein kinase phosphorylation, plays a vital role in regulation of cellular function. PCTAIRE-1 (also known as cyclin-dependent protein kinase (CDK)16), is a Ser/Thr kinase that has been implicated in many ce ...

LRH-1-dependent programming of mitochondrial glutamine processing drives liver cancer

Johan Auwerx, Kristina Schoonjans, Arnaud Comment, Hadrien Charles Edouard Demagny, Dongryeol Ryu, Xu Wang, Emine Can, Norman Lionel Moullan, Pan Xu, Matthias Alexander Sokrates Stein, Maaike Hélène Oosterveer

Various tumors develop addiction to glutamine to support uncontrolled cell proliferation. Here we identify the nuclear receptor liver receptor homolog 1 (LRH-1) as a key regulator in the process of hepatic tumorigenesis through the coordination of a noncan ...

Genetic dissection of the role of BMP signaling for the development of the auditory brainstem nuclei and the large calyx of Held synapse

Elin Kristina Kronander

Synapses are key elements for communication within the complex network of neurons that make up our brain. Interestingly, synaptic connections can differ greatly in form and function, depending on the specific circuit into which they are embedded. In this P ...

A Gating Mechanism of the Serotonin 5-HT3 Receptor

Horst Vogel, Shuguang Yuan

Our recently solved high-resolution structure of the serotonin 5-HT3 receptor (5-HT3R) delivered the first detailed structural insights for a mammalian pentameric ligand-gated ion channel. Based on this structure, we here performed a total of 2.8-μs all-at ...

Single-molecule microscopy to study plasma membrane receptor dynamics

Luc Veya

Cell surface receptors allowthe cell to sense and respond to external signals. Receptor malfunctions are associated with many diseases. The diffusional behavior of receptors is of particular interest to understand how the cell modulates receptor function i ...

Semisynthetic and in Vitro Phosphorylation of Alpha-Synuclein at Y39 Promotes Functional Partly Helical Membrane-Bound States Resembling Those Induced by PD Mutations

Hilal Lashuel, Bruno Claude Daniel Fauvet, Anne-Laure Mahul Mellier, Carole Desobry, Farah El Turk, Ana Jovicic

Alpha-synuclein is a presynaptic protein of poorly understood function that is linked to both genetic and sporadic forms of Parkinson's disease. We have proposed that alpha-synuclein may function specifically at synaptic vesicles docked at the plasma membr ...
