Disease relevance of P2ry6

  • After stab wound injury the additional expression of the P2Y2 and P2Y6 receptors, and an up-regulation of the P2Y1,4 receptor-labeling on astrocytic cell bodies and/or processes was observed [1].
 

High impact information on P2ry6

  • This notion is supported by molecular evidence that demonstrates the presence of P2Y6 receptor transcripts in rat pulmonary arterial smooth muscle [2].
  • Our findings demonstrate the presence of functional P2Y6 receptors in osteoclasts [3].
  • In contrast, UDP or INS48823 (P2Y6 agonists) induced a significant increase in the number of cells exhibiting NF-kappaB activation, a process sensitive to the proteasome inhibitor lactacystin [3].
  • P2Y receptor expression (P2Y2 and P2Y6) was detected in cultured MC and isolated glomeruli, and demonstrated a transient marked increase during anti-Thy1 disease [4].
  • Northern blots revealed an age-related increase in levels of mRNA for P2Y6 receptors in cultures obtained at postnatal days 1 and 5, respectively, but no change in transcripts for P2Y1 and P2Y2 [5].
 

Biological context of P2ry6

 

Associations of P2ry6 with chemical compounds

  • These results indicate that P2Y6 receptors mediate UTP-evoked noradrenaline release from rat sympathetic neurons via activation of protein kinase C, but not inhibition of K(M) channels [5].
  • 3. Uridine nucleotides also inhibited I(K(M)) in P2Y6 cRNA-injected cells (by up to 71% at 10 microM UTP; perforated-patch) [7].
  • 1. The P2Y6 receptor is a uridine nucleotide-specific G protein-linked receptor previously reported to stimulate the phosphoinositide (PI) pathway [7].
 

Other interactions of P2ry6

  • The wide distribution of the uridine nucleotide-activated P2Y2, P2Y4 and P2Y6 receptors suggests a role for UTP as an important extracellular signalling molecule [8].
