Effect of Colivelin on neuronal death induced by Aβ1-43. PCNs were treated with 25 μm Aβ1-43 in the presence or absence of Colivelin or AGA-(C8R)HNG17 (100 am, 1 fm, 10 fm, 100 fm, 1 pm, 10 pm, 100 pm, 1 nm, 10 nm, or 100 nm). Indicated concentrations of neuroprotective peptides were added at 16 h before the onset of Aβ treatment. Cell viability was measured 72 h after Aβ1-43 treatment by WST-8 assay (left) and calcein assay (right). noT, Not transfected. All values in this study indicate means ± SD.
