P2 receptors: intracellular signaling
Pflügers Archiv - European Journal of Physiology, 2006P2 receptors for extracellular nucleotides are divided into two categories: the ion channel receptors (P2X) and the G-protein-coupled receptors (P2Y). For the P2X receptors, signal transduction appears to be relatively simple. Upon activation by extracellular ATP, a channel comprised of P2X receptor subunits opens and allows cations to move across the ...

Renal P2 receptors and hypertension
Acta Physiologica, 2014AbstractThe regulation of extracellular fluid volume is a key component of blood pressure homeostasis. Long‐term blood pressure is stabilized by the acute pressure natriuresis response by which changes in renal perfusion pressure evoke corresponding changes in renal sodium excretion.

Current Topics in Medicinal Chemistry, 2004
The current status of ligand gated ion channel P2X and G protein-coupled P2Y receptor subtypes is described. This is followed by a summary of what is known of the distribution and roles of these receptor subtypes. Potential therapeutic targets of purinoceptors are considered, including those involved in cardiovascular, nervous, respiratory ...

Adenine nucleotides (ADP and ATP) play crucial roles in the physiological process of primary hemostasis and in the development and extension of arterial thrombosis. They act on platelets through three distinct P2 receptors: the P2Y1 and P2Y12 receptors, which are G protein-coupled ADP receptors and the P2X1 receptor, a ligand-gated cation channel ...

P2 receptors and neuronal injury
Pflügers Archiv - European Journal of Physiology, 2006Extracellular adenosine 5'-triphosphate (ATP) was proposed to be an activity-dependent signaling molecule that regulates glia-glia and glia-neuron communications. ATP is a neurotransmitter of its own right and, in addition, a cotransmitter of other classical transmitters such as glutamate or GABA.

Extracellular ATP, P2 receptors, and inflammation
Drug Development Research, 2003AbstractOver the past few years, P2 receptors have emerged as new potential players in the early phases of inflammation in their function of chemotactic receptors, triggers of proinflammatory cytokine release, and cytotoxic molecules. However, more recent data suggest that the role of P2 receptors in immunity is much more widespread and touches the ...

Journal of the Autonomic Nervous System, 2000
Although the emphasis in ATP research has been on postjunctional receptors, there is also evidence for presynaptic receptors regulating transmitter release in the autonomic nervous system. Recent work has attempted to identify similar mechanisms in the central nervous system.

P2-Pyrimidinergic Receptors and Their Ligands
Current Pharmaceutical Design, 2002Pyrimidine nucleotides, including UTP, UDP and UDP-glucose, are important signaling molecules which activate G protein-coupled membrane receptors of the P2Y family. Four distinct pyrimidine nucleotide-sensitive P2Y receptor subtypes have been cloned, P2Y(2), P2Y(4), P2Y(6) and P2Y(14).

P2 receptors in the murine gastrointestinal tract
Neuropharmacology, 2002The actions of adenosine, adenosine 5'-triphosphate (ATP), 2-methylthio adenosine diphosphate ADP (2-MeSADP), 2-methylthio ATP (2-MeSATP), alpha,beta-methylene ATP (alpha,beta-meATP) and uridine triphosphate (UTP) on isolated segments of mouse stomach (fundus), duodenum, ileum and colon were investigated. The localization of P2Y(1), P2Y(2), P2Y(4), P2X(

The platelet P2 receptors in inflammation
Hämostaseologie, 2015SummaryIn addition to their well characterized and established role in haemostasis and thrombosis, platelets contribute to the pathogenesis of inflammation. Adenine nucleotides are signalling molecules that regulate the function of virtually every cell in the body, by interacting with P2 receptors.
