Key Takeaways
• GO:0030072 peptide hormone secretion is the regulated release of a peptide hormone from a cell.
• Peptide hormone secretion depends on vesicle transport to the secretion site followed by exocytosis.
• Secretory dynamics are pulsatile and can be altered in disease, as shown for ACTH and cortisol.
• Peptide hormones such as leptin and ghrelin regulate food intake and body weight in humans.
• Cell volume changes can modulate peptide hormone secretion.
• Peptide hormone-GPCR interactions provide a paradigm for receptor analysis.
Description
GO:0030072 peptide hormone secretion is a biological process defined as the regulated release of a peptide hormone from a cell. Peptide hormones are synthesized and stored in secretory vesicles, then released in response to specific signals, allowing precise control of endocrine and paracrine communication. This process is fundamental for organismal physiology, including metabolic regulation by leptin and ghrelin and stress responses mediated by ACTH and cortisol. Understanding peptide hormone secretion is therefore central to endocrinology, metabolism, and neurobiology research [3,4].

What Happens During peptide hormone secretion?
Vesicle transport to the secretion site
In simple terms: Peptide hormone-containing vesicles move to the right place in the cell before release.
Peptide hormone vesicles are transported to the secretion site for exocytosis, a step essential for regulated release.
Exocytosis and regulated release
In simple terms: The vesicle fuses with the cell membrane and releases the hormone outside.
The regulated release of a peptide hormone from a cell occurs via exocytosis at the secretion site.
Pulsatile dynamics of secretion
In simple terms: Hormone release can occur in pulses rather than steadily.
ACTH and cortisol secretion show dynamic, pulsatile patterns with implications for disease.
Modulation by cell volume
In simple terms: Changes in cell size can affect how much hormone is released.
Cell volume changes can influence peptide hormone secretion.
Peptide hormone-GPCR signaling
In simple terms: Hormones bind receptors to trigger responses.
Peptide hormone-GPCR analyses provide a paradigm for understanding hormone-receptor interactions.
