| Outline of Final Research Achievements |
We investigated an antidepressant like effect of bovine latoferrin (bLf) in repeated forced-swim (FS) stress mice model. Supplemented bLf (1 %) suppressed an immobility time in the FS test. This antidepressant like effect of bLf was disappeared by pre-treatment with a nitric oxide synthase inhibitor or kappa-opioid receptor antagonist. BLf had no effect on the immobility time by combination with fluoxetine, imipramine and pramipexole. While the dopamine D2 receptor mRNA expression in the frontal lobe was significantly increased in the FS treated mice, bLf maintained it as a control level. We couldn’t detect transported bLf nor liposomal bLf in the hippocampus following even after the iv injection.
