Neuropeptide
Neuropeptide — A small protein-like molecule produced by neurons that acts as a chemical messenger in the nervous system, modulating synaptic transmission.
What Is a Neuropeptide?
A neuropeptide is a peptide produced by neurons that functions as a neurotransmitter, neuromodulator, or neurohormone. Neuropeptides are synthesized as large precursors, processed in dense-core vesicles, and released by calcium-dependent exocytosis. The human genome encodes over 100 neuropeptide precursors generating 300+ bioactive neuropeptides.
Major Neuropeptide Families
- Opioid: Enkephalins, endorphins, dynorphins. Pain and reward
- Hypothalamic: Oxytocin, vasopressin, GnRH, CRH, TRH
- GI: Substance P, VIP, CCK, NPY
- Sleep: Orexin/hypocretin, DSIP, galanin
