To test the impact of PP on MT and dilation to flow (FMD) or to acetylcholine (Ach), isolated pressurized mouse posterior cerebral arteries were subjected to either static pressure (SP) or a physiological PP (amplitude: 30\u2009mm Hg; frequency: 550 bpm). Under PP, MT was significantly higher than in SP conditions ( p\u2009&lt;\u20090.05) and was not affected by eNOS inhibition. In contrast, under SP, eNOS inhibition increased ( p\u2009&lt;\u20090.05) MT to levels observed under PP, suggesting that PP may inhibit eNOS. At a shear stress of 20\u2009dyn\/cm\n                    <jats:sup>2<\/jats:sup>\n                    , FMD was lower ( p\u2009&lt;\u20090.05) under SP than PP. Under SP, eNOS-dependent [Formula: see text] production contributed to FMD, while under PP, eNOS-dependent NO was responsible for FMD, indicating that PP favours eNOS coupling. Differences in FMD between pressure conditions were abolished after NOX2 inhibition. In contrast to FMD, Ach-induced dilations were higher ( p\u2009&lt;\u20090.05) under SP than PP. Reactive oxygen species scavenging reduced ( p\u2009&lt;\u20090.05) Ach-dependent dilations under SP, but increased ( p\u2009&lt;\u20090.05) them under PP; hence, under PP, Ach promotes ROS production and limits eNOS-derived NO activity. In conclusion, PP finely regulates eNOS, controlling cerebral artery reactivity.\n
