NLRP3 Inflammasome Activation in the Brain after Global Cerebral Ischemia and Regulation by 17β-Estradiol

Figure 4

Proximity ligation assay demonstrating NLRP3-ASC complex formation after GCI and its suppression by E2. (a) Representative confocal images of proximity ligation assay (Duolink in situ co-IP) show that NLRP3-ASC complex is formed in hippocampal CA1 region of the young adult female rat at day 7 after GCI. This complex formation is robustly suppressed by E2 (magnification = 40x, scale bar = 50 μm). (b) Quantification of fluorescence intensity using MATLAB software shows a statistically significant suppression of complex formation at day 7 after GCI ( sham versus GCI; GCI versus GCI + E2) ( animals per group).
