Activity-dependent adenosine release may be linked to activation of Na+-K+ ATPase : an in vitro rat study [PDF]
, 2014 In the brain, extracellular adenosine increases as a result of neuronal activity. The mechanisms by which this occurs are only incompletely understood. Here we investigate the hypothesis that the Na+ influxes associated with neuronal signalling activate ...

Presynaptic Purinergic Modulation of the Rat Neuro-Muscular Transmission
Current Issues in Molecular Biology, 2023 ATP, being a well-known universal high-energy compound, plays an important role as a signaling molecule and together with its metabolite adenosine they both attenuate the release of acetylcholine in the neuro-muscular synapse acting through membrane P2 ...

Sleep-wake sensitive mechanisms of adenosine release in the basal forebrain of rodents : an in vitro study [PDF]
, 2013 Adenosine acting in the basal forebrain is a key mediator of sleep homeostasis. Extracellular adenosine concentrations increase during wakefulness, especially during prolonged wakefulness and lead to increased sleep pressure and subsequent rebound sleep.

ATP as a Multi-target Danger Signal in the Brain
Frontiers in Neuroscience, 2015 ATP is released in an activity-dependent manner from different cell types in the brain, fulfilling different roles as a neurotransmitter, neuromodulator, astrocyte-to-neuron communication, propagating astrocytic responses and formatting microglia ...

A metabolic immune checkpoint: adenosine in tumor microenvironment
Frontiers in Immunology, 2016 Within tumors, some areas are less oxygenated than others. Since their home ground is under chronic hypoxia, tumor cells adapt to this condition by activating aerobic glycolysis; however, this hypoxic environment is very harsh for incoming immune cells ...

Molecular Vibration-Activity Relationship in the Agonism of Adenosine Receptors [PDF]
Genomics & Informatics, 2013 The molecular vibration-activity relationship in the receptor-ligand interaction of adenosine receptors was investigated by structure similarity, molecular vibration, and hierarchical clustering in a dataset of 46 ligands of adenosine receptors.

Role of cGMP as second messenger of adenosine in the inhibition of renin release
, 1988 Adenosine is known to be a potent inhibitor of renin release from the kidneys. The aim of this study was to investigate the transmembrane signalling avenue that the second messenger of adenosine causes inhibition of renal renin release.
