Abstract

The caudal nucleus of the solitary tract () integrates signals from various stressors, highlighting the role of glucagon-like peptide-1 () and prolactin-releasing peptide () neurons.

  • GLP-1 and PrRP neurons in the cNTS are involved in coordinating responses to both interoceptive and psychogenic stress.
  • Co-activation of GLP-1 and PrRP neurons occurs in reaction to stressful stimuli, indicating their collaborative function.
  • PrRP neurons are positioned downstream of GLP-1 neurons, suggesting a hierarchical relationship in stress response mechanisms.
  • The review identifies potential targets for future research focused on stress-related disorders involving these neuronal pathways.
