The paraventricular nucleus (PVN) of the hypothalamus is a critical neuroendocrine center that integrates stress responses, autonomic function, and homeostasis. Corticotropin-releasing hormone (CRH) neurons in the PVN are the primary drivers of the hypothalamic-pituitary-adrenal (HPA) axis, which is chronically dysregulated in neurodegenerative diseases. Understanding PVN CRH neuron function is essential for developing therapies targeting stress-related pathology in Alzheimer's disease, Parkinson's disease, and related disorders.
Overview
The paraventricular nucleus of the hypothalamus (PVN) is a small, bilateral nucleus located in the anterior hypothalamus adjacent to the third ventricle. PVN CRH neurons represent a key node in the neuroendocrine stress response system, coordinating behavioral, autonomic, and hormonal responses to physical and psychological stressors. [@vale1981]
