Early intervention with a PACAP lactoside following repetitive mild traumatic brain injury prevents persistent LHb hyperactivity and motivational deficits in male mice
This study demonstrates that early intervention with a novel PAC1R agonist (TES2320) following repetitive mild traumatic brain injury in male mice prevents persistent lateral habenula hyperactivity and motivational deficits by restoring PACAP signaling, whereas late intervention fails to improve these outcomes and may induce adverse behavioral effects.
