Fig. 4: Fibrosis inhibits S100A9 expression, which can be ascribed to M2-like macrophages.

a, b The expression of S100A9 in the livers of control and fibrotic mice with or without D-GalN/LPS challenge. (n = 4–7) c, d Comparison of S100A9 expression in fibrotic mice upon acute insult with or without M2-like macrophage depletion. (n = 4–7) e, f Comparison of S100A9 expression in control mice upon acute insult with or without M2-like macrophage transfer. (n = 4–7) GL D-GalN/LPS.
