5-HT-induced vasoconstriction was not significantly impaired in mesenteric (A; n=6–10) arterioles. An attenuated response was observed only in coronary (B; n=6–8) arterioles from groups 24 hr post-exposure to 400 μg CeO2 NPs. Values are means SE. ‡ p ≤ 0.05 vs. 50 μg CeO2 NPs; ^ p ≤ 0.05 vs. 100 μgCeO2 NPs. The right panel represents the responses of the various doses ofCeO2 NPs and was analyzed by nonlinear regression. The left panel highlights the point-to-point differences between the control and CeO2 NP exposed group.
