UASt regulatory sequences drive expression of an Aβ42 peptide carrying an artificial mutation (L17P) that has previously been shown to suppress amyloid fibril formation and toxicity in vitro. The protein is tagged with the Tag:SS(rPENK) signal peptide.
Expression of Hsap\APPAβ1-42.Scer\UAS.art driven by Scer\GAL4elav-C155 results in neurodegeneration, locomotor dysfunction and decreased adult lifespan. 5 and 10 day old mutant flies also manifest 1 hour memory defects.
Scer\GAL4elav-C155- or Scer\GAL4ey-OK107-driven expression of Hsap\APPAβ1-42.Scer\UAS.art results in neuropil degeneration in flies 47 days after eclosion.
Calyxes in the adult mushroom body expressing Scer\GAL4ey-OK107-driven Hsap\APPAβ1-42.Scer\UAS.art start to degenerate 47 days after eclosion.
