Although several single photon emission computed tomography (SPECT) tracers for Aplaques imaging were reported, to the best of our knowledge, no tracer is successful for tau imaging in the living brains. \n\nPURPOSE: In the present study, we have developed a novel SPECT tracer AD-DRK for A and tau deposition for in-vivo detection.\n\nMETHODS: 125I-labeled AD-DRK ([125I] AD-DRK) was designed and synthesized based on our previous publication. The biodistribution was determined in normal mice. The detectability of Ab and tau deposition was investigated by in-vitro and ex-vivo autoradiography in APP and tauopathy mouse models, and post-mortem human brains.\n\nRESULTS: [125I] AD-DRK showed high initial brain uptake with a peak value of approximately 7% of injection dose per ml at 2 minute post-injection and rapid washout thereafter. In vitro autoradiography has clearly demonstrated that there was overt specific binding of [125I] AD-DRK in temporal cortex region of AD or progressive supranuclear palsy (PSP) enriched with A plaques and/or neurofibrillary tangle. Moreover, ex vivo autoradiographic analysis showed that [125I] AD-DRK has higher accumulation in forebrain enriched with A or tau accumulation in AD and tauopathy mouse models compared with normal mouse, implying the utility of AD-DRK for in-vivo imaging for A and/or tau deposition.\n\nCONCLUSION: [125I] AD-DRK has demonstrated high potential as SPECT ligand for diagnosis for AD and/or related tauopathies.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"THE 13TH ASIA OCEANIA
