Lack of endogenous adenosine tonus on sympathetic neurotransmission in spontaneously hypertensive rat mesenteric artery.

open access: yesPLoS ONE, 2014
BackgroundIncreased sympathetic activity has been implicated in hypertension. Adenosine has been shown to play a role in blood flow regulation. In the present study, the endogenous adenosine neuromodulatory role, in mesenteric arteries from normotensive ...

Adenosine Inhibits the Excitatory Synaptic Inputs to Basal Forebrain Cholinergic, GABAergic and Parvalbumin Neurons in mice

open access: yesFrontiers in Neurology, 2013
Coffee and tea contain the stimulants caffeine and theophylline. These compounds act as antagonists of adenosine receptors. Adenosine promotes sleep and its extracellular concentration rises in association with prolonged wakefulness, particularly in the ...

ATP- and Adenosine-Mediated Signaling in the Central Nervous System: Adenosine Stimulates Glutamate Release From Astrocytes via A2a Adenosine Receptors

open access: yesJournal of Pharmacological Sciences, 2004
Adenosine enhanced intracellular Ca2+ concentrations in astrocytes via A2a adenosine receptors involving protein kinase A (PKA) activation. The Ca2+ rise is inhibited by brefeldin A, an inhibitor of vesicular transport; but not by neomycin and U73122 ...

Adenosine A2A receptor binding profile of two antagonists, ST1535 and KW6002: consideration on the presence of atypical adenosine A2A binding sites

open access: yesFrontiers in Psychiatry, 2010
Adenosine A2A receptors seem to exist in typical (more in striatum) and atypical (more in hippocampus and cortex) subtypes. In the present study, we investigated the affinity of two adenosine A2A receptor antagonists, ST1535 [2 butyl -9-methyl-8-(2H-1,2 ...

Development of adenosine signalling in the cerebellum [PDF]

open access: yes
The release and clearance of adenosine are reasonably well-documented in the mature CNS but relatively little is known about how adenosine signalling changes during postnatal development.

ADENOSINE RECEPTORS IN RESPIRATORY DISORDERS AS CHRONIC OBSTRUCTIVE PULMONARY DISEASE AND MALIGNANT PLEURAL MESOTHELIOMA [PDF]

open access: yes, 2012
Adenosine is a purine nucleoside that is commonly expressed in the body and involved in a wide range of physiological processes. The effects of adenosine are mediated through specific G-protein coupled cell surface receptors, named A1, A2A, A2B and A3 ...

Evidence for coordinated induction and repression of ecto-5'-nucleotidase (CD73) and the A2a adenosine receptor in a human B cell line [PDF]

open access: yes, 2003
In the human B cell line P493-6 two mitogenic signals, the EpsteinBarr virus nuclear antigen 2 (EBNA2) and myc, can be independently regulated by means of an estrogen receptor fusion construct or an inducible expression vector, respectively.

The Selective Antagonism of Adenosine A2B Receptors Reduces the Synaptic Failure and Neuronal Death Induced by Oxygen and Glucose Deprivation in Rat CA1 Hippocampus in Vitro

open access: yesFrontiers in Pharmacology, 2018
Ischemia is a multifactorial pathology characterized by different events evolving in time. Immediately after the ischemic insult, primary brain damage is due to the massive increase of extracellular glutamate.
