MnPO inhibition lowers BP more in hypertensive rat models; leaves open whether this nucleus is a viable therapeutic target in human hypertension.
Does inhibition of the Median Preoptic Nucleus affect arterial blood pressure and renal vascular conductance in normotensive and spontaneously hypertensive rats?
The Median Preoptic Nucleus is involved in tonic blood pressure regulation and its increased activity may contribute to sympathoexcitation and hypertension maintenance in spontaneously hypertensive rats.
Lima‐Silveira et al. (2012) studied this question.
