[PDF][PDF] LTP induction boosts glutamate spillover by driving withdrawal of perisynaptic astroglia

…, L Bard, A Panatier, JP Reynolds, O Kopach… - Neuron, 2020 - cell.com
Extrasynaptic actions of glutamate are limited by high-affinity transporters expressed by
perisynaptic astroglial processes (PAPs): this helps maintain point-to-point transmission in …

Persistent inflammation induces GluR2 internalization via NMDA receptor-triggered PKC activation in dorsal horn neurons

…, K Takamiya, A Sotnik, O Kopach… - Journal of …, 2009 - Soc Neuroscience
Spinal cord GluR2-lacking AMPA receptors (AMPARs) contribute to nociceptive
hypersensitivity in persistent pain, but the molecular mechanisms underlying this event are not …

[HTML][HTML] Astrocytes regulate brain extracellular pH via a neuronal activity-dependent bicarbonate shuttle

…, PS Hosford, I Ruminot, O Kopach… - Nature …, 2020 - nature.com
Brain cells continuously produce and release protons into the extracellular space, with the
rate of acid production corresponding to the levels of neuronal activity and metabolism. …

[HTML][HTML] Protein aggregation and calcium dysregulation are hallmarks of familial Parkinson's disease in midbrain dopaminergic neurons

…, C Leighton, RS Saleeb, O Kopach… - npj Parkinson's …, 2022 - nature.com
Mutations in the SNCA gene cause autosomal dominant Parkinson’s disease (PD), with

Mitochondrial ROS control neuronal excitability and cell fate in frontotemporal dementia

N Esteras, O Kopach, M Maiolino… - Alzheimer's & …, 2022 - Wiley Online Library
Introduction The second most common form of early‐onset dementia—frontotemporal dementia
(FTD)—is often characterized by the aggregation of the microtubule‐associated protein …

Inflammation alters trafficking of extrasynaptic AMPA receptors in tonically firing lamina II neurons of the rat spinal dorsal horn

O Kopach, SC Kao, RS Petralia, P Belan, YX Tao… - PAINŽ, 2011 - Elsevier
Peripheral inflammation alters AMPA receptor (AMPAR) subunit trafficking and increases
