Disease relevance of Ptgdr

  • Finally, in a model of contact allergen-induced LC migration, we show that activation of the DP receptor not only inhibits LC emigration but also dramatically reduces the contact hypersensitivity responses after challenge [1].
  • Augmented anti-AChR titers were not seen in strain A mice, but after 6 months of DP treatment increased susceptibility developed to the induction of experimental autoimmune myasthenia gravis [2].
  • The mechanism of induction of cleft palate in DP-treated mice was explored by histological studies using light microscopy [3].
  • Newborn mice treated with DP (1 g/kg/day) showed retarded weight gain, hyperelasticity of skin, and a bizarre forelimb posture with subcutaneous edema on experimental day (ED) 7 [4].
  • Prostaglandin D2 receptor of mastocytoma P-815 cells--possible regulation by phosphorylation and dephosphorylation [5].
 

Psychiatry related information on Ptgdr

  • Two different doses of DP were administered orally for either 5 or 4 consecutive days during the critical period of palatal closure [3].
 

High impact information on Ptgdr

  • Prostanoids, including prostaglandin (PG) D(2), PGE(2), PGF(2alpha), PGI(2) and thromboxane (TX) A(2), exert their actions through specific receptors: DP, EP (EP(1), EP(2), EP(3), EP(4)), FP, IP and TP, respectively [6].
  • Activated mast cells release various chemical mediators, including prostaglandin D2 (PGD2), whose role in allergic asthma has now been investigated by the generation of mice deficient in the PGD receptor (DP) [7].
  • Moreover, DP-/- mice showed only marginal infiltration of eosinophils and failed to develop airway hyperreactivity [7].
  • However, the concentrations of TH2 cytokines and the extent of lymphocyte accumulation in the lung of OVA-challenged DP-/- mice were greatly reduced compared with those in wild-type animals [7].
  • Moreover, the potent DP receptor antagonist BW A868C restores LC migration in infected mice [1].
 

Chemical compound and disease context of Ptgdr

 

Biological context of Ptgdr

  • BW 245C (an agonist for PGD (DP) receptor) blocked the allodynia with an IC50 of 83 ng kg(-1) [8].
  • We have used a molecular genetic approach to investigate the role that DP I and II may play in the association of the desmosomal plaque with cytoplasmic intermediate filaments (IF) [9].
  • Infusion of prostaglandin (PG) D(2) into the lateral ventricle of the brain induced an increase in the amount of non-rapid eye movement sleep in wild-type (WT) mice but not in mice deficient in the PGD receptor (DP) [10].
  • Long-term DP treatment is associated with augmented anti-AChR antibody responses in C3H/He and C57BL/6 mice, and increased susceptibility to experimental autoimmune myasthenia gravis in strain A mice [2].
  • Taken together, our data suggest that the activation of DP receptor by PGD(2) may represent a pathway to control airway DC migration and to limit the activation of T cells in the LNs under steady state conditions, possibly contributing to homeostasis in the lung [11].
 

Anatomical context of Ptgdr

  • 7. These results demonstrate that PGD2 inhibits the nociceptin-evoked allodynia through DP receptors in the spinal cord and that glycine may be involved in this inhibition [8].
  • However, even at 10 microM concentration, AL-8810 did not significantly inhibit functional responses of TP, DP, EP(2), EP(4), receptor subtypes in various cell lines [12].
  • Contraction of the fundus to PGD(2) was significantly enhanced in DP(-/-) mice, and contractions of the fundus and ileum to this PG decreased in FP(-/-) and EP(3)(-/-) mice [13].
  • These results suggest a role for the DP carboxyl terminus in the attachment of IF to the desmosome in either a direct or indirect manner [9].
  • Immunogold localization of COS-7 cells transfected with constructs including the carboxyl terminus of DP demonstrated an accumulation of mutant protein in perinuclear aggregates within which IF subunits were sequestered [9].
 

Associations of Ptgdr with chemical compounds

  • This binding was displaced by unlabeled ligands in the following order: PGD2 > BW 245C (a PGD agonist) > BW A868C (a PGD antagonist) > STA2 (a thromboxane A2 agonist) [14].
  • 3. The blockade of nociceptin-induced allodynia by PGD2 was reversed by the potent and selective DP-receptor antagonist BW A868C in a dose-dependent manner with an ED50 of 42.8 ng kg(-1) [8].
  • In DP(-/-) mice, sulprostone showed increased contraction [13].
  • Control cultures prelabelled with either AA or EPA produced similar amounts of the respective PGF, PGE, and PGD [15].
  • However, phloretin antagonized functional responses of EP2 and DP prostanoid receptors, and also the V1-vasopressin receptor [16].
 

Other interactions of Ptgdr

 

Analytical, diagnostic and therapeutic context of Ptgdr

  • Immunofluorescence staining of WT mouse brain revealed that DP immunoreactivity was dominantly localized in the leptomeninges (LM) of the basal forebrain but that PGD synthase immunoreactivity was widely distributed in the LM of the entire brain [10].
  • Finally, in situ hybridization was performed to localize PGD synthase mRNA [18].
  • PGD synthase activity was determined, and the protein was quantified by Western blot analysis and localized immunohistochemically [18].
  • Intradermal injection of Sm28GST in wild-type (WT), but not in D prostanoid receptor (DP) 1-deficient mice abrogates the departure of LC from the epidermis after TNF-alpha or FITC treatment [19].
  • IgG responses were significantly greater in the DP treated mice than in the control group while IgM responses were not significantly different [20].
