Outline of Final Research Achievements

Based on the neuroinflammation hypothesis of depression, we investigated behavior and brain of the mice which were injected with bacterial endotoxin. Despite of transient activation of the microglia, we could not detect persistent alteration of the marker molecules in the astroglia and oligodendroglia. Minocycline, inhibitor of microglial activation, induced depressive behavior in the tail suspension test in the mice. We also developed a new technique for creating induced microglia-like cells from human peripheral blood. In the MRI study, we accumulated diffuse tensor image of the patients with mood disorder. These results added further information regarding possible interaction between neuroinflammation and depression.
