Identification of atropine-and P2X1 receptor antagonist-reistant, neurogenic contractions of the urinary bladder [PDF]

open access: yes, 2007
Acetylcholine and ATP are excitatory cotransmitters in parasympathetic nerves. We used P2X1 receptor antagonists to further characterize the purinergic component of neurotransmission in isolated detrusor muscle of guinea pig urinary bladder.

Multiple P2Y receptors couple to calcium-dependent, chloride channels in smooth muscle cells of the rat pulmonary artery [PDF]

open access: yes, 2005
Uridine 5'-triphosphate (UTP) and uridine 5'-diphosphate (UDP) act via P2Y receptors to evoke contraction of rat pulmonary arteries, whilst adenosine 5'-triphosphate (ATP) acts via P2X and P2Y receptors.

Synthesis and Structure-Activity Relationships of Pyridoxal-6-arylazo-5'-phosphate and Phosphonate Derivatives as P2 Receptor Antagonists. [PDF]

open access: yes, 1998
Novel analogs of the P2 receptor antagonist pyridoxal-5'-phosphate-6-phenylazo-2',4'-disulfonate (PPADS) were synthesized. Modifications were made through functional group substitution on the sulfophenyl ring and at the phosphate moiety through the ...

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 ...

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.

The relationship between P2X4 and P2X7: a physiologically important interaction? [PDF]

open access: yes, 2013
Purinergic signaling within the kidney is becoming an important focus in the study of renal health and disease. The effectors of ATP signaling, the P2Y and P2X receptors, are expressed to varying extents in and along the nephron.

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.

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

Pharmacological and Molecular Characterisation of P2Y Receptors in Endothelial and Epithelial Cells [PDF]

open access: yes, 2007
Submitted in partial fulfilment of the requirements of the University of Wolverhampton for the degree of Doctor of PhilosophyIn light of the significant modulation of receptor activity previously shown by a peptide (designated L247), designed to mimic ...

In silico identification and experimental validation of cellular uptake and intracellular labeling by a new cell penetrating peptide derived from CDN1

open access: yesDrug Delivery, 2021
Bioactive therapeutic molecules are generally impermeable to the cell membrane, hindering their utility and efficacy. A group of peptides called cell-penetrating peptides (CPPs) were found to have the capability of transporting different types of cargo ...
