Figure Lengend Snippet: Extracellular HMGB1 affects the inflammatory response in lung tissues in ALI. Histopathological changes and injury scores in the left lung are shown for different groups: (A) Control group, LPS group, Anti-HMGB1 group and LPS + anti-HMGB1 group (H&E staining, ×200 magnification). (B) Control group, LPS group, rHMGB1 group and LPS + rHMGB1 group (H&E staining, ×200 magnification). Effects of (C) anti-HMGB1 and (D) rHMGB1 on the lung W/D ratio of LPS-induced ALI mice. Effects of (E) anti-HMGB1 and (F) rHMGB1 on MPO activity in lung tissues and infiltration of inflammatory cells in BALF of LPS-induced ALI mice. All the experiments were repeated more than three times (n=4-6 mice per each group). Data presented is from a selected representative experiment. All data are expressed as the mean ± standard deviation. * P<0.05, ** P<0.01 and *** P<0.001 vs. LPS group; # P<0.05 vs. control group. Extracellular HMGB1 affects the inflammatory response in lung tissues in ALI. Effects of (G) anti-HMGB1 and (H) rHMGB1 on MPO activity in lung tissues and infiltration of inflammatory cells in BALF of LPS-induced ALI mice. Effects of (I) anti-HMGB1 and (J) rHMGB1 on the ELISA results of secretion of inflammatory cytokines (TNF-α, IL-6, MCP-1, IL-1β, and IL-18) in BALF.
