Fig. 3. AAV-mediated expression of AGTRAP in RVLM astrocytes, but not neurons, lowers blood pressure in SHRSPs.

Fig. 3

a, Schematic of the experimental protocol to analyse the effects of AAV-mediated transduction of RVLM astrocytes or neurons with the Agtrap gene. ITR, inverted terminal repeat. b,c, Astrocyte-specific (b) and neuron-specific (c) transgene expression by RVLM injection of AAV9 vectors. Micrographic images of GFP (green) and anti-GFAP (b) or anti-NeuN (c) immunostaining (blue) of RVLM in SHRSPs 15 days after the injection of the AAV9 vectors indicated at the top. Scale bars, 50 μm. Images are representative of three rats. df, MAP values just before (day 1) (d) and 2 weeks after (day 15) (e) AAV injection into the RVLM (P = 0.0222 (GFAP-control versus GFAP-AGTRAP) and P > 0.9999 (NSE-control versus NSE-AGTRAP) (d); P = 0.0229 (column 1 versus 2), P = 0.6864 (column 3 versus 4) (e); n = 6 (GFAP-control), n = 7 (GFAP-AGTRAP), n = 7 (NSE-control) and n = 6 (NSE-AGTRAP) rats) and 24 h urinary noradrenaline excretion (f) (P = 0.0497 (column 1 versus 2), P = 0.7455 (column 3 versus 4); n = 4 rats for each group) in SHRSPs after RVLM injection of AAV9 vectors. Data are mean ± s.e.m. Statistical analysis was performed using two-way repeated-measures ANOVA with Bonferroni’s post hoc multiple-comparison test (d) or one-way ANOVA with Tukey’s post hoc multiple-comparison test (e and f); *P < 0.05.
