ATP mediates NADPH oxidase/ROS generation and COX-2/PGE2 expression in A549 cells: role of P2 receptor-dependent STAT3 activation. [PDF]

open access: yesPLoS ONE, 2013
BACKGROUND: Up-regulation of cyclooxygenase (COX)-2 and its metabolite prostaglandin E(2) (PGE(2)) are frequently implicated in lung inflammation. Extracellular nucleotides, such as ATP have been shown to act via activation of P2 purinoceptors, leading ...

Effects of prolactin on movement disorders and APOE, GFAP, and PRL receptor gene expression following intracerebral hemorrhage in rats [PDF]

open access: yesIranian Journal of Basic Medical Sciences, 2021
Objective(s): Intracerebral hemorrhage (ICH) occurs mostly in the striatum. In ICH, blood prolactin level increases 3-fold. The effects of intracerebroventricular injection (ICV) of prolactin on motor disorders will be investigated. Materials and Methods:

P2 receptors in renal pathophysiology [PDF]

open access: yesPurinergic Signalling, 2009
Our knowledge and understanding of the P2 receptor signalling system in the kidney have increased significantly in the last ten years. The broad range of physiological roles proposed for this receptor system and the variety of P2 receptor subtypes found in the kidney suggest that any disturbance of function may contribute to several pathological ...

P2 receptors and platelet function [PDF]

open access: yesPurinergic Signalling, 2011
Following vessel wall injury, platelets adhere to the exposed subendothelium, become activated and release mediators such as TXA(2) and nucleotides stored at very high concentration in the so-called dense granules. Released nucleotides and other soluble agents act in a positive feedback mechanism to cause further platelet activation and amplify ...

Dynamics of receptor-operated Ca2+ Currents Through TRPC Channels Controlled via the PI(4,5)P2-PLC Signaling Pathway

open access: yesFrontiers in Pharmacology, 2015
Transient receptor potential canonical (TRPC) channels are Ca2+-permeable, nonselective cation channels that carry receptor-operated Ca2+ currents (ROCs) triggered by receptor-induced, phospholipase C (PLC)-catalyzed hydrolysis of phosphatidylinositol 4 ...

P2 receptors and immunity

open access: yesMicrobes and Infection, 2012
Immune cells express receptors for extracellular nucleotides named P2 receptors. P2 receptors transduce signals delivered by nucleotides present in the extracellular environment. Accruing evidence shows that purinergic signalling has a profound effect on multiple immune cell responses such as T lymphocyte proliferation, chemotaxis, cytokine release ...

P2 Receptors in Renal Autoregulation [PDF]

open access: yesCurrent Vascular Pharmacology, 2014
Autoregulation of renal blood flow and glomerular filtration rate is an essential function of the renal microcirculation. While the existence of this phenomenon has been known for many years, the exact mechanisms that underlie this regulatory system remain poorly understood.

ATP- and Adenosine-Mediated Signaling in the Central Nervous System: Adenosine Receptor Activation by ATP Through Rapid and Localized Generation of Adenosine by Ecto-nucleotidases

open access: yesJournal of Pharmacological Sciences, 2004
Extracellular ATP is now recognized as a neurotransmitter or neuromodilator in the nervous system, producing diverse physiological effects by activating multiple P2 receptors.

P2X and P2Y receptor signaling in red blood cells

open access: yesFrontiers in Molecular Biosciences, 2015
Purinergic signaling involves the activation of cell surface P1 and P2 receptors by extracellular nucleosides and nucleotides such as adenosine and adenosine triphosphate (ATP), respectively.

Control of Gut Inflammation by Modulation of Purinergic Signaling

open access: yesFrontiers in Immunology, 2020
Inflammatory bowel disease (IBD) is a serious inflammatory condition of the gastrointestinal tract. Crohn's disease (CD) and ulcerative colitis (UC) are two of the most common IBD manifestations and are both associated with unfettered inflammation, often
