Glycogenolysis and Purinergic Signaling
2014Both ATP and glutamate are on one hand essential metabolites in brain and on the other serve a signaling function as transmitters. However, there is the major difference that the flux in the pathway producing transmitter glutamate is comparable to the rate of glucose metabolism in brain, whereas that producing transmitter ATP is orders of magnitude ...

Brain Research Reviews, 2010
A growing body of evidence indicates that extracellular nucleotides play important roles in the regulation of neuronal and glial functions in the nervous system through P2 purinoceptors. P2 purinoceptors are divided into two families, ionotropic receptors (P2X) and metabotropic receptors (P2Y).

Purinergic signaling in thyroid disease
Purinergic Signalling, 2022It is known that thyroid hormones play pivotal roles in a wide variety of pathological and physiological events. Thyroid diseases, mainly including hyperthyroidism, hypothyroidism, and thyroid cancer, are highly prevalent worldwide health problems and frequently associated with severe clinical manifestations.

Purinergic Signalling and Endothelium
Current Vascular Pharmacology, 2016Purinergic signalling is involved in the control of vascular tone and remodelling. Endothelial cells release purines and pyrimidines in response to changes in blood flow (evoking shear stress) and hypoxia. They then act on P2Y, P2X and P1 receptors on endothelial cells leading to release of EDRF mediated by nitric oxide and prostaglandins and EDHF ...

Wiley Interdisciplinary Reviews: Membrane Transport and Signaling, 2012
AbstractThe concept of purinergic neurotransmission was proposed in 1972, after it was shown that adenosine 5′‐triphosphate (ATP) was a transmitter in non‐adrenergic, non‐cholinergic inhibitory nerves in the guinea pig taenia coli. Subsequently, ATP was identified as a cotransmitter in sympathetic and parasympathetic nerves, and it is now recognized ...

Signaling at Purinergic P2X Receptors
Annual Review of Physiology, 2009P2X receptors are membrane cation channels gated by extracellular ATP. Seven P2X receptor subunits (P2X1-7) are widely distributed in excitable and nonexcitable cells of vertebrates. They play key roles in inter alia afferent signaling (including pain), regulation of renal blood flow, vascular endothelium, and inflammatory responses.

Purinergic Signalling in the Gut
2016The article will begin with the discovery of purinergic inhibitory neuromuscular transmission in the 1960s/1970s, the proposal for purinergic cotransmission in 1976 and the recognition that sympathetic nerves release adenosine 5'-triphosphate (ATP), noradrenaline and neuropeptide Y, while non-adrenergic, non-cholinergic inhibitory nerve cotransmitters ...

Purinergic Signaling in Glioma Progression
2012Among the pathological alterations that give tumor cells invasive potential, purinergic signaling is emerging as an important component. Studies performed in in vitro, in vivo and ex vivo glioma models indicate that alterations in the purinergic signaling are involved in the progression of these tumors.

Introduction to Purinergic Signaling
2019Purinergic signaling was proposed in 1972, after it was demonstrated that adenosine 5'-triphosphate (ATP) was a transmitter in nonadrenergic, noncholinergic inhibitory nerves supplying the guinea-pig taenia coli. Later, ATP was identified as an excitatory cotransmitter in sympathetic and parasympathetic nerves, and it is now apparent that ATP acts as a

Purinergic signalling in brain ischemia
Neuropharmacology, 2016Ischemia is a multifactorial pathology characterized by different events evolving in the time. After ischemia a primary damage due to the early massive increase of extracellular glutamate is followed by activation of resident immune cells, i.e microglia, and production or activation of inflammation mediators.
