A, average mean arterial pressures, measured 24 hrs/day for 4 days by telemetry, in TNFR1−/− IKK2smKo (n=8) and their littermate TNFR1−/− controls (n=6).*P<0.05 vs. TNFR1−/−; two way ANOVA. B-E, acute increases in mean arterial pressure (ΔMAP) of TNFR1−/− IKK2smKo and their littermate TNFR1−/− controls in response to phenylephrine (PE, 10 µg/kg, B), thromboxane A2 agonist (TXA, 30 µg/kg, C), angiotensin II (AngII, 0.3 µg/kg, D), and nitroprusside sodium (NPS, 32 µg/kg, E). n=6/group. *P<0.05 v.s. TNFR1−/−; student t-test.
