26184350 Results demonstrate that the stoichiometry of the heterotrimeric hP2X2/3 receptor is not fixed, but determined by the relative availability of P2X2 and P2X3 subunits
25336328 esophagitis increases mRNA expressions of P2X3 and P2X7 receptors accompanied by up-regulation of TRPV1 and neurotrophic factors (NGF and GDNF).

23959888 Data indicate that MgATP2- activates P2X1 and P2X3, but not P2X2 and P2X4 receptors.
23917247 ATP-gated P2X3 channels in enterochromaffin cells are downregulated in ulcerative colitis.
22963434 Structure and function of P2RX3 is reviewed, and its role in treatment of pain is discussed. [Review Article]
22498660 The effects of single alanine substitutions of amino acid residues in the supposed ATP binding site of the human P2X3 receptor on the agonistic effect of nucleotide analogs.
22378790 one subunit of P2X2 and two subunits of P2X3 form P2X2/3 heteromeric receptors, whereas two subunits of P2X2 and one subunit of P2X6 constitute P2X2/6 receptors
22160848 HEK 293 cells are not permissive for stable P2X3 expression afer a significant time-dependent cell loss; often used in a recmbinant expression system, HEK cells represent a limiting permissive environment for P2X3 receptors.
22052556 An early and broad expression of P2X3 receptors was found in prenatal dorsal root ganglion neurons.

20418063 P2X3 positive fibres in the trigeminal sensory system were significantly increased in burning mouth syndrome patients compared with controls.
20308565 Released ATP activates P2X(3) receptors in the beta-cell plasma membrane, resulting in increased [Ca(2+)](i) and enhanced insulin secretion.
20110693 P2X(1) receptors showed an anti-inflammatory effect reducing NF-kappaB activation and TNF-alpha release whilst P2X(3) receptors mediated opposite response.
19960242 The present data indicate a novel target, P2X3 receptors, to express the action of Cdk5 on membrane proteins involved in pain perception.
19456993 These cells expressed P2X3 receptors. Suburothelial myofibroblasts may be intermediate in processing adenosine triphosphate-mediated sensory activation
18805451 Sodium Ferrulate may inhibit the initiation of pain and primary afferent sensitization mediated by P2X(3) receptor during chronic constriction injury.
18600577 genetic and pharmacological approaches have provided converging evidence that activation of P2X3-containing channels is an important mediator of acute and persistent nociceptive signaling--review
17052768 These data indicate that PKC activation can enhance both the Ca(2+) signal as well as the cation current through P2X(3)R, however it appears that the regulation is unlikely to be a result of direct phosphorylation of the receptor.
15475563 negative residues in the P2X3 ATP receptor ectodomain are structural determinants for desensitization and the Ca2+-sensing modulatory sites
15331767 Effect of acute hypoxia on cloned homo- and heteromeric P2X3 receptors expressed in human embryonic kidney 293 cells.
14520770 in fibers of human tooth pulp ... may play a role in perception of dental pain
12885270 Review. Activation of P2X(3)-containing channels is an important mediator of persistent nociceptive signalling. The data also indicate potential discrete roles for homomeric P2X(3) & heteromeric P2X(2/3) receptor activation in acute & chronic pain.
