Low concentrations of prostaglandin (PG) E(2) enhance platelet aggregation, whereas high concentrations inhibit it. The effects of PGE(2) are mediated through 4 G protein-coupled receptors, termed E-type prostaglindin (EP) receptor EP1, EP2, EP3, and EP4. The platelet-stimulating effect of PGE(2) has been suggested to involve EP3 receptors. Here we analyzed the receptor usage relating to the inhibitory effect of PGE(2).
