Prostaglandin E₂sequentially activates E‐prostanoid receptor‐3 and thromboxane prostanoid receptor to evoke contraction and increase in resistance of the mouse renal vasculature

Although recognized to have an in vivo vasodepressor effect blunted by the vasoconstrictor effect of E-prostanoid receptor-3 (EP3), prostaglandin E2 (PGE2 ) evokes contractions of many vascular beds that are sensitive to antagonizing the thromboxane prostanoid receptor (TP). This study aimed to determine the direct effect of PGE2 on renal arteries and/or the whole renal vasculature and how each of these two receptors is involved in the...
