<p>Internal states including stress and satiety, affect cue-induced feeding behaviors, yet the underlying neural mechanisms remain poorly understood. The nucleus of the solitary tract (NTS), a key hindbrain hub that integrates interoceptive and viscerosensory signals and projects to reward processing nuclei, is anatomically well-positioned to modulate cue-induced feeding behaviors in response to internal state changes. Using behavioral paradigms combined with chemogenetics and fibre photometry, this study investigated the hypothesis that NTS mediates the effects of stress and satiety on cue-induced feeding behaviors via A2 neurons and modulation of ventral tegmental area (VTA) dopamine signaling. We first showed that both foot shock stress and outcome specific satiety (i.e., sucrose prefeed) reduced cue-induced appetitive behavior. Inhibition of NTS neurons only attenuated the suppressive effect of foot shock stress, but not that of outcome specific satiety, indicating that NTS is required for stress-induced suppression of cue-induced appetitive behavior. Further investigation into the contributing neural phenotype revealed that stimulation of NTS A2 neurons reduced conditioned approach and suppressed cue-evoked VTA dopamine neural activity, without any effects on lateral hypothalamus (LH) neuron activity. Together, these findings suggest that NTS neurons mediate the effects of foot shock stress, but not outcome specific satiety, on cue-induced appetitive behavior, in part through activation of NTS A2 neurons and modulation of cue-evoked VTA dopamine neural activity. These results provide an NTS-mediated mechanism through which stress suppresses cue-induced feeding behavior.</p>
