Lateral hypothalamus CRFR1 regulation of chronic binge drinking: divergence along anterior-posterior axis.

ABSTRACT: Binge alcohol drinking increases the risk of developing an alcohol use disorder (AUD) and comorbid psychopathology. The lateral hypothalamus (LH) is a brain structure that integrates cognitive and sensory information to tightly regulate motivated behavior, including binge drinking. Importantly, LH function is vulnerable to modulation by the pro-stress neuropeptide corticotropin-releasing factor (CRF), and acute antagonism of CRF receptor 1 (CRFR1) in the LH blunts binge drinking. However, the role of LH CRFR1 in chronic binge drinking is unknown. We used genetically targeted knockdown (KD) of CRFR1 in the LH of male and female mice followed by three weeks of binge drinking using the "Drinking in the Dark" (DID) model. CRFR1 KD in the posterior LH increased alcohol consumption, independent
