(A, B) In situ real-time morphological changes of PC-12 cells co-incubated with freshly preformed Aβ₄₀ fibrils without (A) or with 50 mg·L⁻¹ Au₂₃(CR)₁₄ (B). (C) Viabilities of PC-12 cells after Aβ₄₀ fibril treatment in the absence (red) and presence (blue) of 50 mg·L⁻¹ Au₂₃(CR)₁₄ for 3, 6, 12, 24 and 48 h. No treatment was included as the blank control (gray). Student's t-test: n = 5, ^*P < 0.05, ^***P < 0.001 vs. Aβ₄₀ fibrils-induced group; ^&P < 0.05, ^&&P < 0.01, ^&&&P < 0.001 vs. control.
