doi: 10.1038/s41598-019-45798-5
Figure Lengend Snippet: (A ) RAGE inhibition decreases histological features of lung injury. Lung injury scores were higher in acid-injured (HCl) than in uninjured piglets (Sham) and acid-injured piglets treated with RAGE antagonist peptide (HCl + RAP) or recombinant sRAGE (HCl + sRAGE) (n = 12 per group). Values are reported as box and whisker plots. The Kruskal-Wallis test, with post-hoc Bonferroni test for pairwise comparisons were used. (B – E) Representative hematoxylin and eosin–stained sections at x20 original magnification of (B) uninjured piglets (Sham), (C) acid-injured piglets (HCl), acid-injured piglets treated with (D) RAGE antagonist peptide (HCl + RAP) or (E) recombinant sRAGE (HCl + sRAGE). There was greater cellularity consisting mainly of neutrophils (black arrowheads), more alveolar wall thickening (white arrowheads), and more areas of atelectasis and increased alveolar disruption, proteinous debris, and hemorrhage (black arrows) in untreated, acid-injured than in uninjured or treated piglets. Scale bars, 100 µm.
Article Snippet: The “sRAGE group” (n = 12) included animals with HCl-induced lung injury that also received intravenous treatment with sRAGE (3 mg.kg −1 ) (Recombinant Human RAGE Fc Chimera, R&D Systems, Minneapolis, MN).
