At 5 min post- ip. injection, there was no significant increase of liraglutide in the brains of mice (A). There was an increase in liraglutide levels in the brains of mice injected with 25 or 250 nmol/kg bw at 30 min (B) and only those injected with the highest dose at 3 h post-injection (C). Brain levels of cAMP were increased 30 min post injection with 25 nmol/kg bw ip.. * = p < 0.05. Values are the mean ± S.E.M.
