VX765, a Specific Caspase-1 Inhibitor, Alleviates Lung Ischemia Reperfusion Injury by Suppressing Endothelial Pyroptosis and Barrier Dysfunction

Figure 7

VX765 treatment attenuated I/R-induced endothelial pyroptosis. (a–h) Mouse lung tissue and serum were collected from each group for the following experiments. (a–c) Caspase-1, GSDMD, and IL-1β mRNA levels measured by RT-qPCR. (d) Protein levels of pro-GSDMD, GSDMD-N, pro-caspase-1, and caspase-1 P20 detected by Western blotting. (e, f) IL-1β protein level in lung tissue and serum measured by ELISA. (g, h) Colabeled CD31 (green) with caspase-1 or GSDMD (red). DAPI was used to stain the cell nuclei by immunofluorescence; vascular endothelium (yellow arrow), scale bar, 200 μm. The data are expressed as ( per group). . vs. control. # vs. I/R.
