Abstract:

Extracellular nucleotides interact with purinergic receptors, which regulate ion transport in a variety of epithelia. With the use of two different human epithelial carcinoma cell lines (HCT8 and Caco-2), we have shown by RT-PCR that the cells express mRNA for P2X1, P2X3, P2X4, P2X5, P2X6, P2X7, P2Y1, P2Y2, P2Y4, P2Y6, P2Y11, and P2Y12 receptors. Protein expression for P2Y1 and P2Y2 receptors was also demonstrated immunohistochemically, and P2X receptor subtype protein was present in the following decreasing order: P2X4 > P2X7 > P2X1 > P2X3 > P2X6 > P2X5 >> P2X2.

In human osteoblast-like MG-63 cells, extracellular ATP increased [3H]thymidine incorporation and cell proliferation and synergistically enhanced platelet-derived growth factor- or insulin-like growth factor I-induced [3H]thymidine incorporation. ATP-induced [3H]thymidine incorporation was mimicked by the nonhydrolyzable ATP analogs adenosine 5′- O-(3-thiotriphosphate) and adenosine 5′-adenylylimidodiphosphate and was inhibited by the P2 purinoceptor antagonist suramin, suggesting involvement of P2 purinoceptors.

Abstract:

ATP, acting through P2X2/P2X3 receptor-channel complexes, plays an important role in carotid body chemoexcitation in response to natural stimuli in the rat. Since the channels are permeable to calcium, P2X activation by ATP should induce changes in intracellular calcium ([Ca2+]i). Here, we describe a novel ex vivo approach using fluorescence [Ca2+]i imaging that allows screening of retrogradely labeled chemoafferent neurons in the petrosal ganglion of the rat. ATP-induced [Ca2+]i responses were characterized at postnatal days (P) 5–8 and P19–25. While all labeled cells showed a brisk increase

Abstract:

Contraction of airway smooth muscle (ASM) plays an important role in the regulation of air flow and is potentially involved in the pathophysiology of certain respiratory diseases. Extracellular nucleotides regulate ASM contraction via purinergic receptors, but the signaling mechanisms involved are not fully understood. Uridine adenosine tetraphosphate (Up4A) contains both pyrimidine and purine moieties, which are known to potentially activate P2X and P2Y receptors. Both P2X and P2Y receptors have been identified in the lung, including airway epithelial cells and ASM. We report here a study of

Coexposure of hypothalamo-neurohypophyseal system explants to ATP and phenylephrine [PE; an α1-adrenergic receptor (α1-AR) agonist] induces an extended elevation in vasopressin and oxytocin (VP/OT) release. New evidence is presented that this extended response is mediated by recruitment of desensitization-resistant ionotropic purinergic receptor subtypes (P2X-Rs): 1) Antagonists of the P2X2/3 and P2X7-Rs truncated the sustained VP/OT release induced by ATP+PE but did not alter the transient response to ATP alone. 2) The P2X2/3 and P2X7-R antagonists did not alter either ATP or ATP+PE-induced i

Abstract:

Nociceptive neurons in the dorsal root ganglia (DRG) are activated by extracellular ATP, implicating P2X receptors as potential mediators of painful stimuli. However, the P2X receptor subtype(s) underlying this activity remain in question. Using electrophysiological techniques, the effects of P2X receptor agonists and antagonists were examined on acutely dissociated adult rat lumbar DRG neurons. Putative P2X-expressing nociceptors were identified by labeling neurons with the lectin IB4. These neurons could be grouped into three categories based on response kinetics to extracellularly applied A

The ligand-gated channels transient receptor potential vanilloid 1 (TRPV1) and P2X3 have been reported to facilitate colorectal afferent neuron sensitization, thus contributing to organ hypersensitivity and pain. In the present study, we hypothesized that TRPV1 and P2X3 cooperate to modulate colorectal nociception and afferent sensitivity. To test this hypothesis, we employed TRPV1-P2X3 double knockout (TPDKO) mice and channel-selective pharmacological antagonists and evaluated combined channel contributions to behavioral responses to colorectal distension (CRD) and afferent fiber responses to

Abstract:

We provide both molecular and pharmacological evidence that the metabotropic, purinergic, P2Y6, P2Y12 and P2Y13 receptors and the ionotropic P2X4 receptor contribute strongly to the rapid calcium response caused by ATP and its analogues in mouse microglia. Real-time PCR demonstrates that the most prevalent P2 receptor in microglia is P2Y6 followed, in order, by P2X4, P2Y12, and P2X7 = P2Y13. Only very small quantities of mRNA for P2Y1, P2Y2, P2Y4, P2Y14, P2X3 and P2X5 were found. Dose-response curves of the rapid calcium response gave a potency order of: 2MeSADP>ADP=UDP=IDP=UTP>ATP>Bz

Structural information for the zebrafish P2X4 receptor in both an agonist bound and unbound resting state provided a major advance in understanding agonist action and has given insight into movement that occurs in the receptor upon ATP binding.

In this thesis the mechanism of antagonist action at the hP2X1 receptor has been investigated through determining properties of chimeras and mutant receptors based on differences between antagonist sensitive and insensitive P2X receptors.

ABSTRACT BACKGROUND AND AIMS: The P2X7 receptor (P2X7R) is an ATP-gated, non-selective cation channel highly expressed on monocytes, macrophages and microglia. Prolonged activation of the P2X7R by ATP leads to cytolytic pore formation and the release of inflammatory mediators including interleukin-1β and prostaglandin E2. Accumulating evidence suggests a role for the P2X7R in neuroinflammation and thus P2X7R antagonists might be useful in diseases including chronic pain, depression and Alzheimer’s disease.

P2X receptors are ATP-gated cation channels. P2X1 receptors are widely expressed throughout the body and have a range of functional roles, e.g. contraction of mesenteric arteries and regulation of blood clotting. The recent crystallisation of the zebra fish P2X4 receptor has provided a major advance in understanding the molecular basis of receptor properties. However, how agonists or antagonists are co-ordinated and the extent of the proposed ligand binding site have not been addressed at a structural level.

Abstract:

The ATP-gated P2X7 receptor (P2X7R) is a non-selective cation channel which senses high extracellular ATP concentrations and has been suggested as a target for the treatment of neuroinflammation and neurodegenerative diseases. The use of P2X7R antagonists may therefore be a viable approach for treating CNS pathologies, including epileptic disorders. Recent studies showed anticonvulsant potential of P2X7R antagonists in certain animal models. To extend this work, we tested three CNS-permeable P2X7R blocker (Brilliant Blue G, AFC-5128, JNJ-47965567) and a natural compound derivative (tanshinone

Abstract:

P2X receptors (P2XRs) activated by ATP are widely expressed throughout the human body and mediate various physiological and pathophysiological roles. Crystal structures have provided a major advance in understanding agonist and subtype selective antagonist actions. However, the molecular basis of antagonism of general antagonists is poorly understood. PPADS is an effective antagonist at most mammalian P2XRs. Previous studies suggested lysine residue 249 (K249) (numbering for P2X1R) was involved in PPADS action. The aim of this study was to determine the PPADS binding site in a molecular model

Abstract:

P2X4 is a purinergic receptor distributed all over the body with various roles. Among them, it was reportedly overexpressed in several neuronal and immune cell types following peripheral nerve injury and its activation leads to neuropathic pain. Several compounds were found to block P2X4 but none has gone into a clinical stage, probably due to insufficient information about the compound itself and P2X4 in general. One of such compounds, 5-(3-Bromophenyl)-1,3-dihydro-2H-Benzofuro[3,2-e]-1,4-diazepin-2-one (5-BDBD) is known to be widely used in P2X4-related studies despite its limited informatio
