Extends mechanistic insights into central mineralocorticoid actions; leaves open whether similar pathways operate in human cardiovascular disease.
Does central aldosterone infusion increase sympathetic nerve activity and oxidative stress via the renin-angiotensin system in normal rats?
Aldosterone acts centrally to upregulate the brain renin-angiotensin system and induce oxidative stress, leading to increased sympathetic nerve activity.
Yang et al. (2007) studied this question.
