Graphical Abstract Highlights d Oxytocin is replaced in its precursor with the insect peptide allatostatin (Ast) d Viral expression induces activity-dependent, synaptic release of bioactive Ast d Ast is expressed in vagal afferents and Ast receptor in Phox2 NTS neurons d This induces a long-term reduction in baroreceptor sensitivity and bodyweight gain

Mots clés: allatostatin; chemogenetics; viral transduction; viscerosensory system; baroreceptor sensitivity; vagus; nucleus of the solitary tract; bodyweight
