Pentapeptides derived from Abeta 1-42 protect neurons from the modulatory effect of Abeta fibrils--an in vitro and in vivo electrophysiological study.


Short fragments and fragment analogues of beta-amyloid 1-42 peptide (Abeta1-42) display a protective effect against Abeta-mediated neurotoxicity. After consideration of our earlier results with in vitro bioassay of synthetic Abeta-recognition peptides and toxic fibrillar amyloids, five pentapeptides were selected as putative neuroprotective agents: Phe-Arg… (More)
