Research Abstract

Prostaglandin D2 (PGD2) has been known to play an important role in allergic inflammation through cell surface receptor CRTH2 and DP1, and also through nuclear receptor PPARg. Our previous study suggested the presence of novel receptor other than these three known receptors for PGD2.
Since we found that PGD2 induced chemokine receptor CCR3 internalization, we studied the possibility that PGD2 act through CCR3. Receptor binding assay and calcium signaling assay using CCR3-transfected cell indicated that PGD2 did not bind/activate CCR3.
