The gut-to-brain axis exhibits significant control over motivated behavior.However, mechanisms supporting this communication are poorly understood.We bunny spa headband reveal that a gut-based bariatric surgery chronically elevates systemic bile acids and attenuates copyright-induced elevations in accumbal dopamine.Notably, this surgery reduces reward-related behavior and psychomotor sensitization to copyright.Utilizing a knockout mouse model, we have determined that a main mediator of these post-operative effects is the Takeda G protein-coupled bile acid pituitary gland in spanish receptor (TGR5).

Viral restoration of TGR5 in the nucleus accumbens of TGR5 knockout animals is sufficient to restore copyright reward, centrally localizing this TGR5-mediated modulation.These findings define TGR5 and bile acid signaling as pharmacological targets for the treatment of copyright abuse and reveal a novel mechanism of gut-to-brain communication.
