Exocytosis of ATP from astrocytes modulates phasic and tonic inhibition in the neocortex. [PDF]
PLoS Biology, 2014 Communication between neuronal and glial cells is important for many brain functions. Astrocytes can modulate synaptic strength via Ca(2+)-stimulated release of various gliotransmitters, including glutamate and ATP.

Purinergic Signaling in Spermatogenesis
Frontiers in Endocrinology, 2022 Adenosine triphosphate (ATP) serves as the essential source of cellular energy. Over the last two decades, however, ATP has also attracted increasing interest as an extracellular signal that activates purinergic plasma membrane receptors of the P2 family.

Purinergic receptors in airway epithelia [PDF]
Current Opinion in Pharmacology, 2009 Nucleotides and nucleosides within the airway surface liquid regulate mucociliary clearance (MCC) activities, the primary innate defense mechanism that removes foreign particles and pathogens from airway surfaces. Nucleotide and nucleoside actions in the airways are mediated mainly by two purinergic receptor subtypes, the Gq-coupled ATP/UTP-sensing ...

Mitochondria Synergize With P2 Receptors to Regulate Human T Cell Function
Frontiers in Immunology, 2020 Intracellular ATP is the universal energy carrier that fuels many cellular processes. However, immune cells can also release a portion of their ATP into the extracellular space.

Cells, 2023 In the cerebral cortex, glutamate activates NMDA receptors (NMDARs), localized in noradrenergic neurons, inducing noradrenaline release that may have a permissive effect on glutamatergic transmission, and therefore, on the modulation of long-term ...

Purine and purinergic receptors [PDF]
Brain and Neuroscience Advances, 2018 Adenosine 5′-triphosphate acts as an extracellular signalling molecule (purinergic signalling), as well as an intracellular energy source. Adenosine 5′-triphosphate receptors have been cloned and characterised. P1 receptors are selective for adenosine, a breakdown product of adenosine 5′-triphosphate after degradation by ectonucleotidases.

Advanced Healthcare Materials, EarlyView.This work presents ARC‐3D, a soft 3D model that recreates how brain support cells, called astrocytes, react to oxidative stress. The system visualizes rapid calcium changes and inflammatory signals, and shows how the drug KDS12025 can protect cells from damage. ARC‐3D offers a simple, reliable way to study early drivers of brain inflammation.

Mediators of Inflammation, 2015 Purinergic mediators such as adenosine 5′-triphosphate (ATP) are released into the extracellular compartment from damaged tissues and activated immune cells. They are then recognized by multiple purinergic P2X and P2Y receptors.

Purinergic Signaling in the Pathophysiology and Treatment of Huntington’s Disease
Frontiers in Neuroscience, 2021 Huntington’s disease (HD) is a devastating, progressive, and fatal neurodegenerative disorder inherited in an autosomal dominant manner. This condition is characterized by motor dysfunction (chorea in the early stage, followed by bradykinesia, dystonia ...
