CD spectroscopic studies
showing β-sheet content and the
inhibitory effects of peptides (A) NT-02, (B) NT-03, and (C) NT-13.
CD spectra show the Aβ42 sample at t = 0 h
(green), and the Aβ42 sample at t = 7 days
(black). Dot blot assay for monitoring Aβ42 aggregation. (D)
Dot blot image for Aβ42 content detected by 6E10. (E) Dot blot
image for Aβ42 fibrillary aggregation inhibition in the presence
of NT peptides detected by OC. (F) Bar diagram of Aβ42 fibrillary
aggregation inhibition by NT peptides. (G) Dot blot image for Aβ42
content detected by 6E10. (H) Dot blot image for Aβ42 oligomeric
aggregation inhibition in the presence of NT peptides detected by
A11. (I) Bar diagram of Aβ42 oligomer inhibition by NT peptides.
Error bars represent mean ± standard deviation (SD), n = 3. Statistical data were analyzed by a one-way ANOVA
test by the multiple comparison test (*p < 0.05,
**p < 0.01, ***p < 0.001,
****p < 0.0001, vs control) using software (GraphPad
Prism, ISI, San Diego, CA).
