(A) LDH enzyme activity detection in serum (left) and lung tissue homogenates (right) of mice in each group. (B) Quantitative analysis of lactate concentrations in serum and lung tissue. (C) Diff-Quik staining images of BALF cell smears (left, red box indicates magnified field) and statistics of eosinophil proportions (right). (D) H&E staining (top, showing inflammatory infiltration) and PAS staining (bottom, showing goblet cells and mucus) of lung tissue sections. Red arrows indicate lesion areas. Right side shows pathological scores. (E) ELISA detection of IL-4, IL-5, and IL-13 concentrations in BALF. (F) ELISA detection of serum total IgE and HDM-specific IgE levels. (G) Flow cytometric analysis of Th1 (IFN-γ + CD4 + ) and Th2 (IL-4 + CD4 + ) cell subsets in mediastinal lymph nodes (mLN) and spleen. Data are expressed as Mean ± SEM. n = 10 per group. ∗P < 0.05, ∗∗P < 0.01, ∗∗∗P < 0.001, ∗∗∗∗P < 0.0001; ns, not significant (One-way ANOVA).

Article Title: Wild-Mouse-Derived Gut Microbiome Transplantation in Laboratory Mice Partly Alleviates House-Dust-Mite-Induced Allergic Airway Inflammation

Figure Lengend Snippet: Compared with SPF-microbiome-associated mice, wild-mouse microbiome-associated mice showed reduced allergic airway inflammation: ( A ) Experimental design showing the timeline of antibiotic treatment (ABX) and microbiome transplantation (FMT) as well as house dust mite (HDM) sensitization and challenges before euthanization of male and female wild mice (wild) and specific pathogen-free (SPF) microbiome-associated BALB/c mice; ( B ) body weight; ( C ) bronchoalveolar fluid (BAL) cell counts; ( D ) numbers of eosinophils (CD11c-CD3-CD19-CD11b+Ly6G-SigF+) in the BAL fluid; ( E ) numbers of neutrophils (CD11c-CD3-CD19-CD11b+Ly6G+) in the BAL fluid; ( F ) numbers of T cells (CD11c-CD3+MHCII-) in the BAL fluid; ( G ) numbers of B cells (CD11c-CD19+MHCII+) in the BAL fluid; ( H ) lung concentration of TNF-α; ( I ) serum concentration of TNF-α; ( J ) serum total IgE concentrations; ( K ) histopathological inflammatory score in lung tissue, including representative images of H&E-stained sections ( L , M ); ( N ) percentage of mucin-positive bronchi, including representative images of PAS-stained sections ( O , P ), are shown for the wild ( n = 13) and SPF ( n = 8) microbiome-associated mice when euthanized at 7 weeks of age. All p values are given (significance < 0.05). The mean and SEM are shown.
