Figure 2. Aβ42 induces astrocyte pyroptosis. (A) Astrocytes were stimulated with the 1 μmol Aβ42 for 48 h were harvested for PI staining and flow cytometry analysis. (B) Scanning electron microscopy was performed to observe astrocyte pyroptosis in the control and Aβ42 groups. (C) Real-time quantitative PCR was used to detect the expression of astrocyte pyroptosis-associated inflammasomes (NLRP1, NLRP3, NLRP4) in the control and Aβ42 groups. *p < 0.05 vs. control group.
