abstract = {Several lines of evidence suggest that the
amyloid-β-peptide (Aβ) plays a central role in the
pathogenesis of Alzheimer's disease (AD). Not only Aβ
fibrils but also small soluble Aβ oligomers in particular
are suspected to be the major toxic species responsible for
disease development and progression. The present study
reports on in vitro and in vivo properties of the Aβ
targeting d-enantiomeric amino acid peptide D3. We show that
next to plaque load and inflammation reduction, oral
application of the peptide improved the cognitive
performance of AD transgenic mice. In addition, we provide
in vitro data elucidating the potential mechanism underlying
the observed in vivo activity of D3. These data suggest that
D3 precipitates toxic Aβ species and converts them into
nonamyloidogenic, nonfibrillar, and nontoxic aggregates
without increasing the concentration of monomeric Aβ. Thus,
D3 exerts an interesting and novel mechanism of action that
abolishes toxic Aβ oligomers and thereby supports their
decisive role in AD development and progression.},
