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.

PET Imaging of Purinergic Receptors
2020Over the recent years, interest in the purinergic signaling system has sparked in the field of positron emission tomography (PET). Purinergic receptors play key roles in physiological and pathological processes, although the exact role in these processes is not always fully understood.

Purinergic receptors in psychiatric disorders
Neuropharmacology, 2016Psychiatric disorders describe different mental or behavioral patterns, causing suffering or poor coping of ordinary life with manifold presentations. Multifactorial processes can contribute to their development and progression. Purinergic neurotransmission and neuromodulation in the brain have attracted increasing therapeutic interest in the field of ...

The enteric purinergic P2Y1 receptor
Current Opinion in Pharmacology, 2006Significant recent discoveries have shown that the P2Y(1) purinergic receptor subtype is expressed in the enteric nervous system and at intestinal neuromuscular junctions. Secretomotor neurons, which release vasoactive intestinal peptide at their junctions with intestinal secretory glands, express the P2Y(1) receptor.

Purinergic and Glutamatergic Receptors on Astroglia
2014Astroglial cells express many neurotransmitter receptors; the receptors to glutamate and ATP being the most abundant. Here, we provide a concise overview on the expression and main properties of astroglial glutamate receptors (ionotropic receptors represented by AMPA and NMDA subtypes) and metabotropic (mainly mGluR5 and mGluR3 subtypes) and ...
