Fig. 3From: PM2.5 exposure aggravates oligomeric amyloid beta-induced neuronal injury and promotes NLRP3 inflammasome activation in an in vitro model of Alzheimer’s diseasePM2.5 exposure increases ROS level in oAβ-stimulated microglia. Microglia with different treatment were incubated with CellROX (green). Meanwhile, cells were co-stained with DAPI (blue). Staining images of microglia with different treatments were shown.
