Successive cleavage of APP by β- and γ-secretases generates the aggregatable amyloid-β peptide (Aβ), while cleavage of APP or Alcα by α- and γ-secretases generates non-aggregatable p3 or p3-Alcα peptides. Aβ and p3-Alcα can be recovered from human cerebrospinal fluid (CSF). We have previously reported alternative processing of APP and Alcα in the CSF of some patients with sporadic mild cognitive impairment (MCI) and AD (SAD).BioMed CentralJournal Articleapplication/pdfhttp://hdl.handle.net/2115/51698https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/51698/1/90_1750-1326-7-16.pdf1750-1326Molecular neurodegeneration7162012enginfo:pmid/22534039info:doi/10.1186/1750-1326-7-16http://creativecommons.org/licenses/by/3.0/publisher
