Abstract
Corticotropin-releasing factor (CRF) is the hallmark brain peptide triggering the response to stress and mediates—in addition to the stimulation of the hypothalamus-pituitary-adrenal (HPA) axis—other hormonal, behavioral, autonomic and visceral components. Earlier reports indicate that somatostatin-28 injected intracerebroventricularly counteracts the acute stress-induced ACTH and catecholamine release. Mounting evidence now supports that activation of brain somatostatin signaling exerts a broader anti-stress effect by blunting the endocrine, autonomic, behavioral (with a focus on food intake) and visceral gastrointestinal motor responses through the involvement of distinct somatostatin receptor subtypes.

The past years have witnessed major advances in our understanding of the underlying mechanisms involved in the bodily response to stress (Chrousos and Zoumakis, 2017)
Mounting evidence supports that the activation of brain sst alleviates many components of the stress response involving brain corticotropin-releasing factor (CRF) signaling
