CB2R expression is increased in BLM-induced mice pulmonary fibrosis. BLM was used to induce pulmonary fibrosis in C57BL/6 mice. (A) Masson staining revealed a degree of pulmonary fibrosis in mice at 7, 14 and 28 days after BLM injection. (n=10 mice). Magnification, ×400. (B) The protein levels of CB2R at 14 and 28 days after BLM injection were detected by western blotting. (C) The mRNA levels of CB2R at 14 and 28 days after BLM injected were detected by reverse transcription-quantitative PCR. Data are presented as the mean ± SEM. **P<0.01 vs. the Con (Day 7) group; ##P<0.01, ###P<0.001 vs. Con (Day 14) group; $$$P<0.001 vs. Con (Day 28) group. Con, control; BLM, bleomycin; CB2R, CB2 receptor.
