Figure Lengend Snippet: rAT reduced pulmonary inflammation in LPS-induced ARDS model mice. ( A–D ) The levels of inflammatory factors, including IL-6 ( A ), TNF-α ( B ), IL-8 ( C ), and hs-CRP ( D ), were decreased in the serum of the rAT-treated group, as detected by ELISA. ( E ) Immunohistochemical staining for F4/80 revealed that rAT treatment reduced the proportion of macrophages in the lung tissue of LPS-induced ARDS model mice. ( F ) Immunohistochemical staining for MRCI, a marker of M2 macrophages, showed that rAT treatment increased the proportion of M2 macrophages in the lung tissue of LPS-induced ARDS model mice. ( G ) Immunohistochemical staining for Ly6G, a marker of neutrophils, showed that rAT treatment reduced the proportion of neutrophils in the lung tissue of LPS-induced ARDS model mice. All the data are presented as the means ± SDs of three independent experiments. One-way ANOVA, *p < 0.05, **p < 0.01, ***p < 0.001, ns, not significant; scale bar, 50 μm.

Figure Lengend Snippet: The efficacy of rAT in mitigating lung injury, suppressing the immune response, and inhibiting the activation of the NF-κB signaling pathway in LPS-induced ARDS mice were diminished by the administration of IL-17a. ( A ) ELISA results demonstrated that the administration of IL17a inhibited the ability of rAT to reduce inflammatory factors, including IL-6, TNF-α, and IL-8, in the serum of LPS-induced ARDS mice. ( B ) The analysis of the wet/dry weight ratio of the lung tissue revealed that the administration of IL17a counteracted the ability of rAT to alleviate pulmonary exudation in LPS-induced ARDS mice. ( C ) The administration of IL17a did not significantly affect the ability of rAT to reduce the number of cells in the BALF of LPS-induced ARDS mice. ( D ) The administration of IL17a attenuated the ability of rAT to reduce the concentrations of proteins in the BALF of LPS-induced ARDS mice. ( E ) Real-time PCR results showed that the administration of IL17a blocked the ability of rAT to downregulate the expression of target genes in the IL17a/NF-κB signaling pathway. ( F ) The protein levels of the NF-κB signaling pathway were assessed by Western blotting, and gray intensity analysis of the blots showed that the administration of IL17a in LPS-induced ARDS mice counteracted the ability of rAT to suppress the phosphorylation of IκBα, IKKα/β, and P65. The data are expressed as the means ± SDs (n=3 in each group). One-way ANOVA, *p < 0.05, **p < 0.01, ***p < 0.001, and ns not significant.
