Direct observation of ATP-induced conformational changes in single P2X(4) receptors. [PDF]

PLoS Biology, 2009
The ATP-gated P2X(4) receptor is a cation channel, which is important in various pathophysiological events. The architecture of the P2X(4) receptor in the activated state and how to change its structure in response to ATP binding are not fully understood.

ATP signaling in the integrative neural center of Aplysia californica

Scientific Reports, 2021
ATP and its ionotropic P2X receptors are components of the most ancient signaling system. However, little is known about the distribution and function of purinergic transmission in invertebrates.

Emerging key roles for P2X receptors in the kidney [PDF]

, 2013
P2X ionotropic non-selective cation channels are expressed throughout the kidney and are activated in a paracrine or autocrine manner following the binding of extracellular ATP and related extracellular nucleotides.

Inhibitory role of supraspinal P2X₃/P2X_2/3 subtypes on nociception in rats

Molecular Pain, 2006
Extracellular ATP is known to mediate synaptic transmission as a neurotransmitter or a neuromodulator via ionotropic P2X and metabotropic P2Y receptors.

P2X receptors: epithelial ion channels and regulators of salt and water transport. [PDF]

, 2008
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 ...

Identification of ionotrophic purinergic receptors in Huh-7 cells and their response towards structural proteins of HCV genotype 3a

Virology Journal, 2011
Hepatitis C virus (HCV) is a major health problem in developing countries including Pakistan. Chronic HCV infection results in progressive liver disease including fibrosis, cirrhosis, insulin resistance and eventually hepatocellular carcinoma (HCC ...

Introduction and perspective, historical note

Frontiers in Cellular Neuroscience, 2013
P2 nucleotide receptors were proposed to consist of two subfamilies based on pharmacology in 1985, named P2X and P2Y receptors. Later, this was confirmed following cloning of the receptors for nucleotides and studies of transduction mechanisms in the ...

Lack of neuroprotection in the absence of P2X7 receptors in toxin-induced animal models of Parkinson's disease

Molecular Neurodegeneration, 2011
Background Previous studies indicate a role of P2X7 receptors in processes that lead to neuronal death. The main objective of our study was to examine whether genetic deletion or pharmacological blockade of P2X7 receptors influenced dopaminergic cell ...
