The paraventricular nucleus in heart failure

点击翻译按钮获取中文摘要

Heart failure is a severely debilitating condition with a poor prognosis. It is characterized by retention of fluid and high nervous activity especially to the kidneys and the heart. Even with the best current treatment available, patients with heart failure still suffer from abnormally high nerve activity to the further detriment of this condition. The successful completion of this project will provide considerable insight into the role of the brain in the elevated nerve activity in heart failure. It will also provide us with a significant understanding of the role in reflex sympathetic nerve regulation of an important brain region known as the hypothalamic paraventricular nucleus (PVN). Our findings will help us understand the nature of the neurotransmitters contributing to the reflex nerve regulation and the specific neurons within the PVN involved. This knowledge could help us to identify novel potential therapeutic targets within the brain to alleviate the problems observed in heart failure.
