Current Opinion in Pharmacology, 2003
Activation of P2Y(1) and P2Y(12) receptors, through secreted ADP that is stimulated by agonists such as thrombin, thromboxane and collagen, is a major mechanism of platelet activation. P2X(1) receptors also participate in platelet shape change and potentiation of calcium mobilization.

Annals of the New York Academy of Sciences, 1990
In rabbits the contractile response of the urinary bladder is only partially due to cholinergic innervation since atropine does not completely block neuronally mediated contractions. In the human bladder this atropine resistance is controversial with some reporting atropine resistance in vitro while others have stated that the atropine resistance is ...

Purinergic receptors in airway hydration
Biochemical Pharmacology, 2021Airway epithelial purinergic receptors control key components of the mucociliary clearance (MCC), the dominant component of pulmonary host defense. In healthy airways, the periciliary liquid (PCL) is optimally hydrated, thus acting as an efficient lubricant layer over which the mucus layer moves by ciliary force.

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 receptors, prostacyclin and atherosclerosis
Pharmacological Research, 1992Over the last decade, evidence has been provided that endothelial cells have a metabolic function in order to maintain blood vessel homeostasis. The endothelium releases relaxing and contracting factors in response to endogenous or exogenous substances such as acetylcholine, calcimycine, adenosine 5'triphosphate (ATP), bradykinin, arachidonic acid and ...

Abstract The term purinergic receptor (or purinoceptor ) was first introduced to describe classes of membrane receptors that, when activated by either neurally released ATP (P2 purinoceptor ) or its breakdown product adenosine (P1 purinoceptor ), mediated relaxation of gut smooth muscle (Burnstock 1972, 1978).

Current Pharmaceutical Design, 2009
There is a brief summary of the early background literature about purinergic signalling and its involvement in pain, of ATP storage, release and ectoenzymatic breakdown and of the current classification of receptor subtypes for purines and pyrimidines. The review then focuses on purinergic mechanosensory transduction involved in visceral, cutaneous and

Purinergic receptors in auditory neurotransmission
Hearing Research, 2003The effects of ATP (adenosine 5' triphosphate) analogs on gross cochlear potentials and single primary afferent discharge properties were studied by intracochlear perfusion in anesthetized guinea pigs. ATP-gamma-S was most potent, with betagammamethylene-ATP and Bz-ATP being significantly less effective.

Purinergic receptors in gastrointestinal inflammation
American Journal of Physiology-Gastrointestinal and Liver Physiology, 2008Purinergic receptors comprise a family of transmembrane receptors that are activated by extracellular nucleosides and nucleotides. The two major classes of purinergic receptors, P1 and P2, are expressed widely in the gastrointestinal tract as well as immune cells.
