a Changes in mean arterial pressure (MAP) and heart rate (HR); b low frequency (LF) of the systolic blood pressure (SBP); and c baroreflex function in rats fed either the standard diet (SD) or high-fat diet (HFD) that received injections of AAV2-CBA-eGFP or AAV2-CBA-AT2R (arrows in a) into the nucleus of the solitary tract 3 weeks after starting the SD or HFD. The results are presented as the means ± SEM from the SD-eGFP (n = 6), HFD-eGFP (n = 7), SD-AT2 (n = 5), and HFD-AT2 (n = 7) group. In a, data were analyzed using two-way ANOVA followed by the Student–Newman–Keuls test; *different from week 0; # different from the SD group; & different from the HFD-eGFP group; P < 0.05. In b and c, data were analyzed using one-way ANOVA followed by the Student–Newman–Keuls test; *different from the SD group; # different from the HFD-eGFP group; P < 0.05
