| Outline of Final Research Achievements |
To identify the subtype-specific biomarkers of Alzheimer’s disease (AD), iPS cells, which are derived from AD patients who showed accumulation of amyloid beta peptide inside or outside of neurons (intracellular and extracellular AD subtype, respectively), were differentiated into neurons and the culture media were purified and analyzed by liquid chromatography-tandem mass spectrometry (LC-MSMS) for comprehensive and quantitative analysis. We selected several biomarker candidates for intracellular, extracellular and common AD . We next quantitated the levels of the candidates in the culture media by multiplexed-MRM (multiple reaction monitoring) method and have confirmed three candidates show the same change as analyzed by LC-MSMS.
