Prolactin Producing Neurons is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Prolactin (PRL)-producing neurons are a subset of hypothalamic neuroendocrine cells that synthesize and release prolactin, a hormone traditionally associated with lactation but with important neuroprotective and immunomodulatory functions relevant to neurodegenerative diseases.
Prolactin-producing neurons are primarily located in:
- Hypothalamic arcuate nucleus (ARC)
- Dorsomedial hypothalamus
- Periventricular nucleus
- Some subsets in the preoptic area
- PRL: Prolactin
- PRLR: Prolactin receptor
- D2R: Dopamine D2 receptor (negative regulation)
- Prolactin (primary)
- May co-express other hypothalamic peptides depending on subset
- Primary regulator of lactogenesis
- Modulates hypothalamic-pituitary-gonadal axis
- Influences maternal behavior
- Promotes oligodendrocyte differentiation
- Supports myelination
- Neurotrophic effects
- Anti-inflammatory properties
- Modulates microglial activity
- Supports blood-brain barrier integrity
