MBL restoration ameliorated silica-induced pulmonary fibrosis in mice. (AD) MBL−/− mice were tail vein injected with MBL-expressed AAV or control AAV combined with intratracheally injected with silica suspension (5mg silica in 50μL sterile PBS) for 35 d. The lung tissues and sera were collected at the end of the experiment. (A) Histological analysis of lung tissues was determined by H&E staining. (B) Hydroxyproline levels in lung tissues were detected. (C) FCM analysis was performed to evaluate Th17 or Treg frequency in lung tissues, HLN, and BALF. (D) Expression of AhR in CD4+ T cells was detected by FCM assay. *p < 0.05, **p < 0.01. The data represent three independent experiments with similar results.
