Due to a production error, there was a mistake in Figure 1, Figure 2 and Figure 3 as published. The images for Figure 1, Figure 2 and Figure 3 were replaced with the images for Supplementary Figure S1, Supplementary Figure S2, and Supplementary Figure S3, respectively. The correct images for Figure 1, Figure 2 and Figure 3 appear below.

FIGURE 1

FIGURE 1. Expression of GSDMD and pyroptosis-related molecules was significantly increased after kainic acid-induced SE. (A,B) WB bands of GSDMD, GSDMD-N, and β-actin proteins in the ipsilateral and contralateral hippocampus. (C–F) Statistical analyses of GSDMD, GSDMD-N, and β-actin proteins in the ipsilateral and contralateral hippocampus. (G,H) WB bands of caspase-1, IL-1β, and β-actin proteins in the ipsilateral and contralateral hippocampus. (I–L) Statistical analyses of caspase-1, IL-1β, and β-actin proteins in the ipsilateral and contralateral hippocampus (n = 3 in each group, *p < 0.05, **p < 0.01, and ***p < 0.001).

FIGURE 2

FIGURE 2. Clasmatodendritic astrocytes co-labeled with GSDMD after SE. (A–C) Representative images of GSDMD (red)/GFAP (green), GSDMD (red)/NeuN (green), and GSDMD (red)/Iba-1 (green) staining in hippocampal slices from mice at day 7 after kainic acid injection. (D) Microphotographs of GSDMD (red) and GFAP (green) staining in the CA1 region of the hippocampus in the sham, SE-1d, SE-7d, and SE-21d groups (bar = 50 µm). (E) Typical GSDMD-positive clasmatodendritic astrocytes in the CA1 region of the hippocampus at 7 days after SE (bar = 12.5 µm). (F–H) Statistical analyses of the number of GSDMD-positive clasmatodendritic astrocytes and total astrocytes in the CA1, CA3, and DG regions (n = 3 in each group, asterisks represent the total astrocytes in comparison with the sham group, *p < 0.05, **p < 0.01, and ***p < 0.001; well number represents the clasmatodendritic astrocytes in comparison with the sham group, ###p < 0.001). (I) Microphotographs of Iba1 (red) staining in the CA1, CA3, and DG regions of the hippocampus in the sham, SE-1d, SE-7d, and SE-21d groups. (J) Statistical analyses of the number of Iba1-positive cells in the CA1, CA3, and DG regions (n = 3 in each group, asterisks represent the comparison with the sham group, *p < 0.05, **p < 0.01, and ***p < 0.001).

FIGURE 3

FIGURE 3. DMF intervention inhibited the expression of GSDMD-N and attenuated astrocytic clasmatodendrosis. (A–C) WB bands and statistical analyses of GSDMD, GSDMD-N, and β-actin proteins in the ipsilateral and contralateral hippocampus in the SE + CMC and SE + DMF groups (n = 6 in each group, asterisks represent the comparison with the SE + CMC group, *p < 0.05, **p < 0.01, and ***p < 0.001). (D–F) WB bands and statistical analyses of pro-caspase-1, cleaved-caspase1, and β-actin proteins in the ipsilateral and contralateral hippocampus (n = 6 in each group, asterisks indicate the comparison with the SE + CMC group, *p < 0.05, **p < 0.01, and ***p < 0.001). (G–I) WB bands and statistical analyses of pro-IL-1β, cleaved–IL-1β, and β-actin proteins in the ipsilateral and contralateral hippocampus (n = 6 in each group, asterisks indicate the comparison with the SE + CMC group, *p < 0.05, **p < 0.01, and ***p < 0.001). (J) Microphotographs of GSDMD (red) and GFAP (green) staining in the CA1 region of the hippocampus in the SE + CMC and SE + DMF groups. (K) Statistical analyses of the number of GSDMD-positive clasmatodendritic astrocytes and total astrocytes in the CA1 region in the SE + CMC and SE + DMF groups (n = 3 in each group, asterisks represents the total astrocytes in comparison with the sham group, ***p < 0.001; well number represents the clasmatodendritic astrocytes in comparison with the sham group, ###p < 0.001).
