Erratum

In the article "Silencing of FSTL1 Alleviated LPS-Induced Inflammatory Damage and Oxidative Damage in Human Bronchial Epithelial Cells via BMP4/KLF4 Axis" [Int Arch Allergy Immunol. 2022;183(7):785-795. https://doi.org/10.1159/000521852] by Yi Zhang, Liping Yan, Jiao Yang and Xiangni Li, after publication, the authors identified an error in Figure 5a of their article.Fig. 5.Silencing FSTL1 promoted BMP4 and KLF4 expression. a Co-IP was used to study whether FSTL1 interacts directly with KLF4. b The expression levels of KLF4 and BMP4 were detected by Western blotting. c Quantitative value of BMP4 expression level. d Quantitative value of KLF4 expression level. ##p < 0.01 versus LPS + si-NC group. $p < 0.05 versus LPS + si-FSTL1 group. Co-IP, co-immunoprecipitation.Figure 5a was erroneously submitted by the authors as a draft sketch. The correct complete Figure 5 is shown here.The original article has been updated to reflect this.
