We found the PGD2 receptors DP1 and chemoattractant receptor homologous molecule expressed on T helper type 2 cells (CRTH2) localized in neurons of the dorsal, and motoneurons in the ventral horn. | |||||||||||||||
| |||||||||||||||
|
This alternative lipid blocked interactions between PGD2 and its receptor on neutrophils, preventing the process of migration across the endothelial barrier. | |||||||||||||||
| |||||||||||||||
|
Importantly, a number of studies have shown that the presence of PGD2 can in turn inhibit the ability of DCs to migrate out of the lungs or the skin during an inflammatory response, although the molecular mechanism by which this inhibition is achieved remains undescribed [35],[36]. | |||||||||||||||
| |||||||||||||||
|
Saturation ligand binding isotherms demonstrated high-affinity binding of [3H]PGD2, with a Kd of 8.8 +/- 0.8 nM. | |||||||||||||||
| |||||||||||||||
|
Competition binding assays with a panel unlabeled prostanoids demonstrated an order of affinity of 13,14-dihydro-15-keto-PGD2 (DK-PGD2) >or= 15-deoxy-Delta12,14-PGJ2 (15d-PGJ2) >or= PGD2 >or= PGJ2. [3H]PGD2 binding was also displaced by the nonsteroidal anti-inflammatory drug indomethacin, with a Ki value of 1.04 +/- 0.13 microM. | |||||||||||||||
| |||||||||||||||
|
Indomethacin, sulindac sulfide, and zomepirac displaced [3H]PGD2 binding at the mouse CRTH2 receptor (mCRTH2) with comparable affinity (Ki = 1.5 +/- 0.1, 2.5 +/- 0.4, and 3.3 +/- 0.3 microM, respectively). | |||||||||||||||
| |||||||||||||||
|
Although it is also involved in acute inflammatory states, such as asthma [31,32], PGD2 is now increasingly recognized as an important mediator of the resolution of inflammation. | |||||||||||||||
| |||||||||||||||
|
However, deletion of mPGES-1 permits rediversion of the PGH2 substrate to other PG synthases and augmented formation of PGI2 and PGD2 mitigates this effect. | |||||||||||||||
| |||||||||||||||
|
This chimeric IPN-V/DPVI-C receptor acquired the ability to bind [3H]PGD2 and [3H]PGE2 without decreasing the affinities of the mIP receptor to [3H]iloprost and [3H]PGE1. | |||||||||||||||
| |||||||||||||||
|
The mDP receptor bound only [3H]PGD2 with a Kd value of 43 nM. | |||||||||||||||
| |||||||||||||||
|
This receptor did not bind [3H]PGD2, [3H]PGE2, and [3H]PGF2alpha. | |||||||||||||||
| |||||||||||||||
|
Magnolol was less potent on reducing PGD2 formation in rat mast cell than that of indomethacin. | |||||||||||||||
| |||||||||||||||
|
Four of these receptor subtypes bind PGE2 (EP1-EP4), two bind PGD2 (DP1 and DP2), and the other receptors bind PGF2, PGI2, and TxA2 (FP, IP, and TP) respectively (Narumiya et al. 1999; Breyer et al. 2001; Hirai et al. 2001). | |||||||||||||||
| |||||||||||||||
|
Prostanoids are lipid mediators generated from AA by the enzymatic action of the cyclooxygenases (COX) 1 and 2 to form the intermediate PGH2, with subsequent metabolism to specific prostanoid species (e.g., PGD2, PGE2, PGF2? | |||||||||||||||

Four of these receptor subtypes bind PGE2 (EP1-EP4), two bind PGD2 (DP1 and DP2), and the other receptors bind PGF2, PGI2, and TxA2 (FP, IP, and TP) respectively (Narumiya et al. 1999; Breyer et al. 2001; Hirai et al. 2001). | |||||||||||||||

|
CONCLUSIONS: Our results confirm that the action of DA D2 and D3 receptors could be dependent on the dopaminergic state, in this case modified by the action of morphine.
