Article Title: High-salt diet promotes atopic dermatitis by partially enhancing intestinal SGK1/ENaC signaling and destroying gut Lactobacillus -maintained systemic type 1 interferon

doi: 10.3389/fcimb.2026.1794494

Figure Lengend Snippet: Effect of Lactobacillus supplementation on atopic dermatitis (AD) and its correlation with gut homeostasis and the type 1 interferon (IFN1) level in mice receiving a high-salt diet (HSD). MC903 (45 μM, 20 μl/cm 2 ) was topically applied to the exposed nape of wild-type ( wt ) or Ifnar1 knockout ( Ifnar1 KO ) mice (8–10 weeks old, eight male mice per group) for 12 consecutive days. Mice synchronously received HSD and SVT or Lactobacillus ( Lactob ) supplementation for 2 weeks prior to and during MC903 application. The mice were then anesthetized and related samples were obtained. Skin lesions, hematoxylin–eosin (HE) staining of the lesions, and ileum zonula occludens-1 (ZO-1) protein expression (A) (bar represents 100 μm), serum IgE (B) , serum IL-4 and IL-13 (C) , total serum IFN1 level (D) , related proteins in the ileum (E) , β-diversity based on principal coordinate analysis (F) , and the relative abundance of the main differential gut microbiota at species level (G) are shown. Statistics: One-way ANOVA + Bonferroni’s tests. n.s., p > 0.05; * p < 0.05, ** p < 0.01, *** p < 0.001.
