Figure Lengend Snippet: Fig. 1. Overexpression of CSF-1R in CD206+ M2 macrophages. (A) Flow cytometry analysis of CSF-1R and CD206 expression in F4/80+ macrophages. Right panels: Quantified data in sorted F4/80+ macrophages. Results are expressed as means ± SD ( n = 3; ∗∗P < 0.01). (B) Representative results for coimmunostaining of CD206 and CSF-1R in the lung sections from bleomycin-treated mice. Representative images are shown. Bar = 20 μm. (C) Immunohistochemistry staining of CSF-1R and CD206 in the lung sections of IPF patients. Representative images are shown. Bar = 50 μm. (D-F) Single cell atlas of IPF patients according to dataset GSE122960. (D) Upper panels: Cellular populations identified. Lower panels: t-distributed stochastic neighbor embedding (t-SNE) depicting cell clusters originating either from a donor or from IPF patients. (E) Expression of CSF-1R for the cell types defined above each panel. (F) Percentage of cells with non-zero CSF-1R expression. (G) Kaplan– Meier survival analyses of IPF patients based on the expression of CSF-1R according to dataset GSE70866. (H) Immunofluorescence staining of CSF-1R and α-SMA on mouse lung tissues. Representative images are shown. Bar = 50 μm.

Figure Lengend Snippet: Fig. 5. (A) Schematic diagram of the BLZ-loaded NPs therapy procedure. (B) Inhibitory effects of scrNP-BLZ@Mn-Cur or M2NP-BLZ@Mn-Cur on CSF-1R phosphorylation in lung tissues. (C) Representative flow cytometry results is shown to identify pulmonary macrophage subsets from lung digests in BLM-treated mice. Right panels: Quantified data in sorted F4/80+ macrophages ( n = 3, means ± SD). (D) Cell differential from BAL fluid was counted by Diff-Quik staining ( n = 5; mean ± SD; ∗p < 0.05). (E) The level of TGF- β1, IL-6, IL-11, and TNF- α in lung tissues were determined by ELISA. Results are expressed as means ± SD ( n = 3; ∗∗p < 0.01, ∗p < 0.05).
