Fig. 4.
Effect of Aβ peptide and trolox in the expression of p-tau. Cultured neurons treated with 5 µM of Aβ showed significantly higher expression of p-tau (p < 0.05). Trolox reverted the Aβ-induced effects. Representative Western blots are shown. In all cases, values are means ± SD of 9 experiments. **p < 0.05 compared to control values. +p < 0.05 compared to values obtained with Aβ.
