AA13 protected primary cultured neuroglia against Aβ‐induced cytotoxicity. (A, B) Both astrocytes and microglia were treated by 10 μmol/L Aβ
1‐42 with or without 10 μmol/L AA13 and AA13 alone, respectively, for 24 h. Cell viability was determined using MTT assay. (C, D) The morphological alterations of astrocytes and microglia were visualized by a phase‐contrast microscope. *P<.05, **P<.01, ***P<.001 compared with control group. ##P<.01 compared with Aβ‐treated group
