Renin-producing juxtaglomerular (JG) cells act as baroreceptors: they sense changes in perfusion pressure, and this sensing mechanism controls renin release [ 1...

... baroreceptor activation and impaired BRS (baroreflex sensitivity). In the present study we tested the hypothesis that the increased carotid artery stiffness in TGA patients was associated with reduced cardiovagal BRS. We studied 32 TGA patients aged 9–19 years, 12±3 years after surgical repair and 32 age...

...Marie Sumitani; E. M. Krieger 1. The extent of reversal of baroreceptor resetting after pressure normalization was studied in rats with renal hypertension of up to 6 months duration. The aortas of these rats when compared with those of 2 month hypertensive rats were thicker (44%) and had a larger...
