Rescue of cell viability after treatment with Aβ 1–42 oligomers co-incubated with D19, D20 or D19/20, as measured by MTS assay in primary cortical neurons.

<p>Cell toxicity was partially rescued when cells were treated with oligomer reactions of Aβ 1–42 co-incubated with peptide (Aβ42+peptide). No rescue was observed if cells were treated sequentially with Aβ 1–42 oligomers and then peptide oligomers (Aβ 1-42(+peptide)), without prior co-incubation. Values shown are normalized to Aβ 1–42 toxicity levels. n ≥ 6. ** p < 0.01.
