Effect of BLT2 receptor agonists on vascular tone in mouse mesenteric arteries. Relaxation responses to the BLT2 receptor agonists CAY10583 (A) and leukotriene B4 (C) in mouse mesenteric arteries preconstricted with either phenylephrine (●) or U46619 (▽). CAY10583 had no effect on the basal tension (B). Each value represents the mean ± SE; n = 4–15. #P < 0.05 compared with U46619-preconstricted arteries.
