Disease relevance of P2ry2

 

High impact information on P2ry2

  • Pressure-induced increases in membrane capacitance (a measure of apical plasma membrane surface area where 1 microF approximately equals 1 cm2) were inhibited by the serosal, but not mucosal, addition of apyrase or the purinergic receptor antagonist PPADS [5].
  • This purinergic receptor has been described chiefly in cells of hemopoietic origin such as T cells, thymocytes, monocytes, macrophages, and phagocytic cells of thymic reticulum [6].
  • These results suggest that during inflammatory conditions, IL-1beta reveals a functional P2Y2 signaling pathway in astrocytes that results in a dramatic increase in the levels of free AA [7].
  • ATP receptor mediated Ca2+ signaling was recorded from Bergmann glial cells in cerebellar slices obtained from mice of different ages (postnatal days 6 to 45) [8].
  • Since ADP, AMP, and adenosine (in descending order) were less potent or ineffective in inducing the cation conductance, the involvement of a P2 purinergic receptor is proposed [9].
 

Biological context of P2ry2

 

Anatomical context of P2ry2

  • In summary, these results indicate that both the P2Y2 and P2Y4 receptors are present in the luminal membrane of mouse distal colonic mucosa, and stimulation of these receptors leads to K+ secretion [10].
  • Taken together, these results point to the presence of functional P2Y1 (ADP), P2Y2 (ATP, UTP) and P2Y6 (UDP) receptors on murine aorta endothelial cells [15].
  • Thoracic aorta segments (width 2 mm) of P2Y2-deficient and wild-type (WT) mice were mounted in organ baths to measure isometric force development and intracellular calcium signalling.Relaxations evoked by ADP, UDP and acetylcholine were identical in knockout and WT mice, indicating that the receptors for these agonists function normally [16].
  • We have used two-electrode voltage-clamp analysis and ion substitution to further characterize these P2z purinergic receptor-induced currents as expressed in mRNA-injected oocytes [17].
  • 6 These results indicate the presence of several P2Y receptors coupled to an increase in intracellular calcium in the SCG: ADP-sensitive P2Y1 receptors and UDP-sensitive P2Y6 receptors in SCG neurons and glial cells, a novel UTP-sensitive P2Y receptor in SCG neurons and UTP- and ATP-sensitive P2Y2 receptors in SCG glia [18].
 

Associations of P2ry2 with chemical compounds

  • The luminal UTP-stimulated K+ secretion was still present in P2Y2 receptor knock-out mice, but significantly reduced (DeltaV(te): 0.83 +/- 0.26 mV) compared to wild-type littermates (DeltaV(te): 2.08 +/- 0.52 mV, n = 9) [10].
  • Furthermore, in vitro and in vivo administration of purinergic receptor antagonists suramin and pyridoxalphosphate-6-azophenyl-2',4'-disulfonic acid (PPADS) blocked the expression of HSP25 immunoreactivity in sustentacular cells [19].
  • P2Y2-deficient mice showed impaired ATP- and adenosine 5'[gamma-thio] triphosphate (ATPgammaS)-evoked relaxation, suggesting that in WT mice, ATP and ATPgammaS activate predominantly the P2Y2 subtype [16].
  • The P2U purinoceptor-selective agonist UTP and the P2Y purinoceptor-selective agonist ADP beta S induce inositol 1,4,5-trisphosphate generation in a concentration-dependent manner with maximal effective concentrations of approximately 100 microM [20].
  • The role of epithelial P2Y2 and P2Y4 receptors in the regulation of intestinal chloride secretion [21].
 

Other interactions of P2ry2

  • Luminal UTP-stimulated K+ secretion was completely absent in P2Y2/P2Y4 double receptor KO mice [10].
  • Pharmacological screening with purinergic ligands indicated the presence of P2Y1 and P2Y2/4 receptors linked to the activation of a K+ current and P2X receptors, including P2X7, linked to the activation of a nonselective cationic current [22].
  • For UTP, it was unclear whether P2Y2, P2Y6 or yet another subtype was involved [16].
  • The former, but not the latter, was inhibited by U-73122, indicating that the former was via the P2Y2 receptor and the latter via the P2X7 receptor [23].
  • Use of the polymerase chain reaction coupled with reverse transcription showed that mouse clonal early proximal tubule (S1) cell line (NF-5) and outer medullary collecting tubule (OMCT) cells expressed mRNA for P2X4, P2Y1 and P2Y2 purinoceptors [24].
 

Analytical, diagnostic and therapeutic context of P2ry2

  • Coexpression of TRPV1 mRNA with P2Y2 mRNA, but not P2Y1 mRNA, was determined in the rat lumbar DRG using in situ hybridization histochemistry [1].
  • Transcripts of the purinergic receptor P2Y2 subtype were amplified by polymerase chain reaction from the cDNA of granulosa cells or cumulus cells [25].
  • Total cell count in bronchoalveolar lavage fluids at 4 h and levels of IL-6 and macrophage inflammatory protein-2 in lung homogenates at 24 h postchallenge were significantly reduced in P2Y1/P2Y2-/- mice relative to wild-type mice [2].
  • 4. ATP and UTP applied to either the apical or the basolateral bath equi-potently stimulated ISC while 'purified' ADP and UDP had no effect consistent with P2Y2 purinoceptors, the expression of which was confirmed using RT-PCR [26].
  • In a co-culture of NHEKs and DRG neurons, mechanical-stimulation-evoked Ca2+ waves in NHEKs caused an increase in [Ca2+]i in the adjacent DRG neurons, which was also dependent on extracellular ATP and the activation of P2Y2 receptors [27].
