Figure 4

Effect of central MR blockade on arterial pressure. SPIR was centrally given via an ICV injection once daily for 7 days in TASK+/+ and TASK−/− mice (n = 8 for each genotype). (A) Shows a schematic diagram of ICV injection (left) and a half slice image (right) of ICV injection of the Evans Blue. Application of SPIR considerably lowered 24-h average SBP (B) and DBP (C) TASK−/− mice, without significant impact on TASK+/+ mice. No obvious difference was found in HR (D) in both genotypes. **p < 0.01, ***p < 0.001 as indicated by two-way ANOVA with Tukey’s multiple comparisons test. ICV, intracerebroventricular; LV, lateral ventricle; 3V, third ventricle.
