Effect of anti-inflammatory agents on expression of amyloidogenic proteins (A, B). The expression of APP, BACE and C99 were detected by Western blotting using specific antibodies in astrocytes (A) and neuronal cells (B). β-Actin protein was used as an internal control. Each blot is representative for five experiments. Sulindac sulfide inhibits expression of amyloidogenic proteins (C) and Aβ1–42 secretion (D) induced by LPS in cultured neuronal cells. Combined Sulindac sulfide (12.5, 25, 50 μM) and LPS treatment for 24 hr were used. (C), The expression of APP, BACE and C99 in neuronal cells was detected by Western blotting using specific antibodies. β-Actin protein was used as an internal control. (D), Media were collected to determine an Aβ1–42 secretion by ELISA. Data represent mean ± S.E. of three experiments with duplicated. *Significant different from LPS treated group (p < 0.05).
