Preventive effects of Congo red against Wt-Aβ42 or E22P-Aβ42-induced neurotoxicity and intracellular ROS accumulation. (A, B) In MTT test, cultures were treated with Congo red and (A) Wt-Aβ42 (20 μM) or (B) E22P-Aβ42 (5 μM) for 48 h. (C, D) In DCF assay, cultures were incubated with Congo red and (C) Wt-Aβ42 (20 μM) or (D) E22P-Aβ42 (5 μM) for 24 h. The intrinsic fluorescence of Congo red was subtracted: (∗∗) P < 0.01, (∗∗∗) P < 0.001 vs vehicle, (#) P < 0.05, (###) P < 0.001.
