Activation of the hypothalamic–pituitary–adrenal (HPA) axis and subsequent release of glucocorticoid hormones is a key response that mobilizes fuel stores to meet energy demands1,2,3,4,5. Despite the importance of the HPA axis response, the neural mechanisms that drive its activation during energy deficit are unknown. Here, we show that fasting-activated hypothalamic agouti-related peptide (AgRP)-expressing neurons trigger and are essential for fasting-induced HPA axis activation. AgRP neurons do so through projections to the paraventricular hypothalamus (PVH), where, in a mechanism not previously described for AgRP neurons, they presynaptically inhibit the terminals of tonically active GABAergic afferents from the bed nucleus of the stria terminalis (BNST) that otherwise restrain activity of corticotrophin-releasing hormone (CRH)-expressing neurons. This disinhibition of PVHCrh neurons requires γ-aminobutyric acid (GABA)/GABA-B receptor signalling and potently activates the HPA axis. Notably, stimulation of the HPA axis by AgRP neurons is independent of their induction of hunger, showing that these canonical ‘hunger neurons’ drive many distinctly different adaptations to the fasted state. Together, our findings identify the neural basis for fasting-induced HPA axis activation and uncover a unique means by which AgRP neurons activate downstream neurons: through presynaptic inhibition of GABAergic afferents. Given the potency of this disinhibition of tonically active BNST afferents, other activators of the HPA axis, such as psychological stress, may also work by reducing BNST inhibitory tone onto PVHCrh neurons."}],"oa":1,"type":"journal_article","oa_version":"Submitted Version","author":[{"first_name":"Amelia May Barnett","last_name":"Douglass","id":"de5f6fda-80fb-11ef-996f-a8c4ecd8e289","full_name":"Douglass, Amelia May Barnett","orcid":"0000-0001-5398-6473"},{"last_name":"Resch","first_name":"Jon M.","full_name":"Resch, Jon M."},{"first_name":"Joseph C.","last_name":"Madara","full_name":"Madara, Joseph C."},{"full_name":"Kucukdereli, Hakan","last_name":"Kucukdereli","first_name":"Hakan"},{"full_name":"Yizhar, Ofer","last_name":"Yizhar","first_name":"Ofer"},{"last_name":"Grama","first_name":"Abhinav","full_name":"Grama, Abhinav"},{"full_name":"Yamagata, Masahito","first_name":"Masahito","last_name":"Yamagata"},{"full_name":"Yang, Zongfang","first_name":"Zongfang","last_name":"Yang"},{"full_name":"Lowell, Bradford B.","first_name":"Bradford B.","last_name":"Lowell"}],"language":[{"iso":"eng"}],"date_updated":"2025-07-10T11:51:40Z","status":"public","volume":620,"OA_place":"repository"}
