Outline of Final Research Achievements |
We examined molecules that relate to microglial activation and investigated a linkage between neurogenesis and neuroinflammation using AD-like animal models (SAMP8 mice and naturally-developed demented macaque confirmed by [11C]PIB for amyloid pathology) by developing methods with which we were able to quantify the amount of neurogenesis and determine the types of microglial activation: protective or inflammatory. With the SAMP8 mice, a combination of Nestin promoter LAT4 system and [18F]dFMT enabled to illustrate the neurogenesis but the signal was small and ex vivo postmortem brain imaging was found to be necessary. Using a CB2R ligand permitted to depict microglial activation, but we found a more sensitive probe and method system necessary for examining these two phenomena in vivo in a living single animal.
