Findings remain preclinical; leaves open translation of medullary angiotensin actions to human therapy.
Does injection of angiotensin II or angiotensin-(1-7) into the nucleus tractus solitarii reduce blood pressure and heart rate in rats with unilateral sinoaortic denervation?
Angiotensin II and angiotensin-(1-7) exert biological activity via receptor-mediated actions in the dorsal medulla oblongata, with angiotensin II effects not requiring intact baroreceptor input.
Campagnole‐Santos et al. (1990) studied this question.
