Supraoptic Nucleus Vasopressin Neurons In Neurodegeneration is an important cell type in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Vasopressin (arginine vasopressin, AVP) neurons in the supraoptic nucleus (SON) play critical roles in body fluid homeostasis and have been implicated in various neurodegenerative processes. These neurons are part of the hypothalamic-neurohypophyseal system.
¶ Distribution and Properties
- Location: Supraoptic nucleus of the hypothalamus
- Neurotransmitter: Arginine vasopressin (peptide)
- Marker expression: Vasopressin, oxytocin, neurophysin I
- Projections: Posterior pituitary, limbic system
AVP neurons in AD show:
- Altered vasopressin levels: Dysregulated AVP secretion
- Memory function: AVP modulates memory consolidation
- Circadian rhythms: Disrupted in AD
- Autonomic dysfunction: AVP regulates blood pressure
- Sleep disorders: AVP affects sleep-wake cycles
- Fluid balance: Dysregulation contributes to symptoms
- Autonomic failure: Severe dysregulation of AVP
- Blood pressure control: Orthostatic hypotension
- Fluid homeostasis: Impaired osmoregulation
