In the article “The Prion Protein Ligand, Stress-Inducible Phosphoprotein 1, Regulates Amyloid-β Oligomer Toxicity” by Valeriy G. Ostapchenko, Flavio H. Beraldo, Amro H. Mohammad, Yu-Feng Xie, Pedro H. F. Hirata, Ana C. Magalhaes, Guillaume Lamour, Hongbin Li, Andrzej Maciejewski, Jullian C. Belrose, Bianca L. Teixeira, Margaret Fahnestock, Sergio T. Ferreira, Neil R. Cashman, Glaucia N. M. Hajj, Michael F. Jackson, Wing-Yiu Choy, John F. MacDonald, Vilma R. Martins, Vania F. Prado, and Marco A. M. Prado, which appeared on pages 16552–16564 of the October 16, 2013 issue, the authors regret an error in Figure 6D, where the panel for scrambled Aβ peptide treatment was accidentally duplicated. The data and the quantification were rechecked and the mistake was found only in the representative image. The correct Figure 6 is shown below.
