Pharmacology of the Adenosine A3 Receptor in the Vasculature and Essential Hypertension. [PDF]

PLoS ONE, 2016
BACKGROUND:Essential hypertension is considered to be a multifactorial disorder and its aetiology has yet to be clearly identified. As the adenosine receptors have a significant role in mediating vasodilation, alterations in their structures or ...

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

PLoS 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 Receptors and the Kidney [PDF]

, 2009
The autacoid, adenosine, is present in the normoxic kidney and generated in the cytosol as well as at extracellular sites. The rate of adenosine formation is enhanced when the rate of ATP hydrolysis prevails over the rate of ATP synthesis during increased tubular transport work or during oxygen deficiency.

Intracellular ATP influences synaptic plasticity in area CA1 of rat hippocampus via metabolism to adenosine and activity-dependent activation of adenosine A1 receptors [PDF]

, 2011
The extent to which brain slices reflect the energetic status of the in vivo brain has been a subject of debate. We addressed this issue to investigate the recovery of energetic parameters and adenine nucleotides in rat hippocampal slices and the ...

A2B Adenosine Receptor and Cancer [PDF]

International Journal of Molecular Sciences, 2019
There are four subtypes of adenosine receptors (ARs), named A1, A2A, A2B and A3, all of which are G protein-coupled receptors (GPCRs). Locally produced adenosine is a suppressant in anti-tumor immune surveillance. The A2BAR, coupled to both Gαs and Gαi G proteins, is one of the several GPCRs that are expressed in a significantly higher level in certain

Adenosine-mediated modulation of ventral horn interneurons and spinal motoneurons in neonatal mice

, 2015
The authors are grateful for support from the Wellcome Trust.Neuromodulation allows neural networks to adapt to varying environmental and biomechanical demands. Purinergic signalling is known to be an important modulatory system in many parts of the CNS,

Adenosine A1 receptor activation mediates the developmental shift at layer 5 pyramidal cell synapses and is a determinant of mature synaptic strength [PDF]

, 2013
During the first postnatal month glutamatergic synapses between layer 5 pyramidal cells in the rodent neocortex switch from an immature state exhibiting high probability of neurotransmitter release, large unitary amplitude and synaptic depression to a ...

Adenosine receptors and cancer

Biochimica et Biophysica Acta (BBA) - Biomembranes, 2011
Adenosine is a ubiquitous signaling molecule whose physiological functions are mediated by its interaction with four G-protein-coupled receptor subtypes, termed A(1), A(2A), A(2B) and A(3). As a result of increased metabolic rates, this nucleoside is released from a variety of cells throughout the body in concentrations that can have a profound impact ...

Chemical Probes for the Adenosine Receptors [PDF]

Pharmaceuticals, 2019
Research on the adenosine receptors has been supported by the continuous discovery of new chemical probes characterized by more and more affinity and selectivity for the single adenosine receptor subtypes (A1, A2A, A2B and A3 adenosine receptors). Furthermore, the development of new techniques for the detection of G protein-coupled receptors (GPCR ...

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

Journal 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 ...
