Fig. 10

Recombinant ACE2 protein ameliorated ALI induced by coexposed to SARS-CoV-2 spike RBD and LPS. A The representative images of H&E staining of the lung tissues. The left panel, 100 × , scale bar = 100 μm; the right panel, 400×, scale bar = 100 μm. B The lung injury score was calculated according to the results of H&E staining. (40 fields for each sample were determined.) C The wet-to-dry weight ratio of the lung tissues was determined (n = 4 for each group). D The cell counts in the BALF were determined (n = 6 for each group). E The protein concentrations of the BALF were determined by BCA (n = 6 for each group). F Schematic diagram of the mechanism of the rescue effects of rACE2. Data are shown as mean ± S.D., *P < 0.05 and **P < 0.01
