Background Adrenal chromaffin cells mediate acute responses to stress through the release of epinephrine. Chromaffin cell function is regulated by several receptors, present both in adrenergic (AD) and noradrenergic (NA) cells.

P2X1 receptors and the endothelium
Adenosine triphosphate (ATP) is now established as a principle vaso-active mediator in the vasculature. Its actions on arteries are complex, and are mediated by the P2X and P2Y receptor families.

Purinergic receptor mediated calcium signalling in urothelial cells [PDF]
Non-neuronal ATP released from the urothelium in response to bladder stretch is a key modulator of bladder mechanosensation. Whilst non-neuronal ATP acts on the underlying bladder afferent nerves to facilitate sensation, there is also the potential for ...

P2Y receptors in the gastrointestinal epithelium [PDF]
AbstractP2Y receptors are widely expressed in all gastrointestinal (GI) epithelia. Commonly, one epithelial tissue or cell expresses several P2Y receptors, which are located in both the apical and basolateral membranes. In almost all studied GI tissues, stimulation of P2Y receptors activates ion secretion, either that of NaCl, KCl, NaHCO3, or KHCO3. In

P2X receptors: epithelial ion channels and regulators of salt and water transport. [PDF]
When the results from electrophysiological studies of renal epithelial cells are combined with data from in vivo tubule microperfusion experiments and immunohistochemical surveys of the nephron, the accumulated evidence suggests that ATP-gated ion ...

Apical membrane P2Y4 purinergic receptor controls K+ secretion by strial marginal cell epithelium
Background It was previously shown that K+ secretion by strial marginal cell epithelium is under the control of G-protein coupled receptors of the P2Y family in the apical membrane.

Ontogeny of purinergic receptor-regulated Ca2+ signaling in mouse cortical collecting duct epithelium [PDF]
Changes in ATP-induced increase in {[}Ca2+], during collecting duct ontogeny were studied in primary monolayer cultures of mouse ureteric bud (UB) and cortical collecting duct (CCD) cells by Fura-PE3 fluorescence ratio imaging.

Purinergic P2Y 2 receptors, G-protein coupled receptors that primarily couple with Gαq/11-proteins, are activated equipotently by adenosine-5′-triphosphate (ATP) and uridine-5′-triphosphate.

P2Y receptors in lung inflammation [PDF]
AbstractNucleotides, e.g., adenosine‐5′‐triphosphate (ATP), can be released into the extracellular space under acute or chronic inflammatory conditions and have been shown to serve as potent immunomodulators or danger signals involved in the initiation and maintenance of immune responses.

Purinergic Signaling in Liver Pathophysiology
Extracellular nucleosides and nucleotides activate a group of G protein-coupled receptors (GPCRs) known as purinergic receptors, comprising adenosine and P2Y receptors. Furthermore, purinergic P2X ion channels are activated by ATP.
