[PDF][PDF] A local glutamate-glutamine cycle sustains synaptic excitatory transmitter release

H Tani, CG Dulla, Z Farzampour, A Taylor-Weiner… - Neuron, 2014 - cell.com
… effectively blocked by g-DGG. We found that the effect of g-DGG was enhanced even after
only two iterations of HFSs (Figure 5C). In slices pretreated with MSO, the effect of g-DGG was …

[PDF][PDF] Adenosine and ATP link PCO2 to cortical excitability via pH

CG Dulla, P Dobelis, T Pearson, BG Frenguelli… - Neuron, 2005 - cell.com
In addition to affecting respiration and vascular tone, deviations from normal CO 2 alter pH,
consciousness, and seizure propensity. Outside the brainstem, however, the mechanisms by …

Traumatic brain injury increases cortical glutamate network activity by compromising GABAergic control

…, D Hampton, G Tesco, CG Dulla - Cerebral …, 2015 - academic.oup.com
Traumatic brain injury (TBI) is a major risk factor for developing pharmaco-resistant epilepsy.
Although disruptions in brain circuitry are associated with TBI, the precise mechanisms by …

Neuronal activity drives pathway-specific depolarization of peripheral astrocyte processes

…, PG Haydon, ES Boyden, AE Cohen, CG Dulla - Nature …, 2022 - nature.com
Astrocytes are glial cells that interact with neuronal synapses via their distal processes,
where they remove glutamate and potassium (K + ) from the extracellular space following …

Glutamate clearance is locally modulated by presynaptic neuronal activity in the cerebral cortex

M Armbruster, E Hanson, CG Dulla - Journal of Neuroscience, 2016 - Soc Neuroscience
Excitatory amino acid transporters (EAATs) are abundantly expressed by astrocytes, rapidly
remove glutamate from the extracellular environment, and restrict the temporal and spatial …

Astrocytic BDNF signaling within the ventromedial hypothalamus regulates energy homeostasis

D Ameroso, A Meng, S Chen, J Felsted, CG Dulla… - Nature …, 2022 - nature.com
Brain-derived neurotrophic factor (BDNF) is essential for maintaining energy and glucose
balance within the central nervous system. Because the study of its metabolic actions has …

Tonic activation of GluN2C/GluN2D-containing NMDA receptors by ambient glutamate facilitates cortical interneuron maturation

…, F Noubary, J Chadchankar, CG Dulla - Journal of …, 2019 - Soc Neuroscience
Developing cortical GABAergic interneurons rely on genetic programs, neuronal activity,
and environmental cues to construct inhibitory circuits during early postnatal development. …

Effects of fluorescent glutamate indicators on neurotransmitter diffusion and uptake

M Armbruster, CG Dulla, JS Diamond - Elife, 2020 - elifesciences.org
Genetically encoded fluorescent glutamate indicators (iGluSnFRs) enable neurotransmitter
release and diffusion to be visualized in intact tissue. Synaptic iGluSnFR signal time courses …

Astrocytic glutamate uptake is slow and does not limit neuronal NMDA receptor activation in the neonatal neocortex

…, D Cantu, L Andresen, A Taylor, NC Danbolt, CG Dulla - Glia, 2015 - Wiley Online Library
Glutamate uptake by astrocytes controls the time course of glutamate in the extracellular
space and affects neurotransmission, synaptogenesis, and circuit development. Astrocytic …

[HTML][HTML] Novel approaches to prevent epileptogenesis after traumatic brain injury

CG Dulla, A Pitkänen - Neurotherapeutics, 2021 - Elsevier
Traumatic brain injury (TBI) is defined as an alteration in brain function or other evidence of
brain pathology caused by an external force. When epilepsy develops following TBI, it is …
