Overview

Arginine vasopressin (AVP), also known as antidiuretic hormone (ADH), is a 9-amino acid neuropeptide encoded by the AVP gene on chromosome 20p13 that plays critical roles in water retention, blood pressure regulation, and social behavior["@du1954"]. Beyond its peripheral endocrine functions, AVP acts as a central neuropeptide modulating stress responses, social cognition, memory consolidation, and circadian rhythms—all processes relevant to neurodegenerative diseases.

Normal Function

The AVP gene encodes preprovasopressin, which is processed to mature AVP (arginine vasopressin) along with neurophysin I and a glycopeptide. AVP is synthesized primarily in the supraoptic nucleus (SON) and paraventricular nucleus (PVN) of the hypothalamus[@burbach2001].

Peripheral Functions

• Water reabsorption in kidney collecting ducts
• Vasoconstriction and blood pressure regulation
• ACTH release from pituitary (modulates HPA axis)
• Liver glycogenolysis

Central Functions

• Social behavior and pair-bonding
• Stress response modulation
• Memory consolidation
• Circadian rhythm regulation
• Thermoregulation

Neuropeptide Co-transmission

• Co-released with oxytocin in some [neurons](/entities/neurons)
• Interactions with CRH and HPA axis
• Modulates monoaminergic systems

Expression Pattern

AVP is expressed in brain regions involved in social and homeostatic functions:

| Brain Region | Expression Level | Functional Significance |
|--------------|------------------|------------------------|
| Supraoptic Nucleus | Very High | Water balance, stress |
| Paraventricular Nucleus | Very High | HPA axis modulation |
| Bed Nucleus of Stria Terminalis | High | Social behavior |
| Amygdala | Moderate | Emotional processing |
| [Hippocampus](/brain-regions/hippocampus) | Low-Moderate | Memory modulation |
| Lateral Septum | High | Social recognition |

Molecular Mechanisms

AVP signals through three G-protein coupled receptors (V1a, V1b, V2), with V1a and V1b being primarily expressed in the brain[@barberis1998]:

Receptor Signaling

• V1a (AVPR1A): Gq-coupled, phospholipase C activation, increased intracellular calcium
• V1b (AVPR1B): Gq-coupled, similar to V1a, pituitary expression
• V2 (AVPR2): Gs-coupled, adenylate cyclase activation, renal water reabsorption

Central Signaling Pathways

• Phospholipase C activation
• Protein kinase C activation
• Calcium mobilization
• MAPK pathway modulation

Disease Associations

Alzheimer's Disease

Parkinson's Disease

Diabetes Insipidus

Syndrome of Inappropriate ADH Secretion (SIADH)

Anxiety and Social Behavior

Therapeutic Implications

Vasopressin Receptor Ligands

CNS Applications

• V1a modulators for anxiety disorders
• Social behavior enhancement
• Memory consolidation effects
• Circadian rhythm disorders

Research Directions

• Brain-penetrant V1a antagonists
• Selective V1b compounds
• AVP as biomarker for neurodegeneration

Animal Models

Knockout Mice

• V1a knockout: altered social behavior
• V1b knockout: reduced stress response
• AVP knockout: diabetes insipidus phenotype

Transgenic Models

• AVP overexpression: enhanced social memory
• Human AVPR1A transgenic studies

Clinical Relevance

AVP system modulation has therapeutic potential:

• Neurodegeneration: Effects on memory and stress
• Psychiatric: Anxiety, depression, social behavior
• Endocrine: Diabetes insipidus, SIADH
• Cardiovascular: Blood pressure regulation
