The hypothalamic paraventricular nucleus plays a critical role in regulating renal blood flow during hyperthermia and contributes to elevated renal sympathetic nerve activity in heart failure.
This review summarizes evidence on the hypothalamic paraventricular nucleus's role in regulating renal sympathetic nerve activity and blood flow, particularly in the context of hyperthermia and heart failure.
No immediate clinical application for PVN modulation; leaves open whether targeting it improves renal outcomes in HF.
The hypothalamic paraventricular nucleus is a key integrative area in the brain involved in influencing sympathetic nerve activity and in the release of hormones or releasing factors that contribute to regulating body fluid homeostasis and endocrine function. The endocrine and hormonal regulatory function of the paraventricular nucleus is well studied, but the regulation of sympathetic nerve activity and blood flow by this region is less clear. Here we review the critical role of the paraventricular nucleus in regulating renal blood blow during hyperthermia and the evidence pointing to an important pathophysiological role of the paraventricular nucleus in the elevated renal sympathetic nerve activity that is a characteristic of heart failure.

Emilio Badoer (2010) conducted a review in Heart failure and hyperthermia. Hypothalamic paraventricular nucleus (PVN) activity was evaluated. The hypothalamic paraventricular nucleus plays a critical role in regulating renal blood flow during hyperthermia and contributes to elevated renal sympathetic nerve activity in heart failure.
