PT‐BsAb inhalation modulates macrophage subtypes in the injured heart. a) Schematic illustrating the overall design of animal experiments to test the effect on macrophages of different treatments. b) Quantification of CD68⁺ macrophages after different treatments at 4 h (before treatments), 3 days, 7 days, and 14 days (with treatments). The result of NT‐BsAbs group was not shown. c) Quantification of M1‐like and M2‐like macrophages in the heart of mice treated with PT‐BsAbs via inhalation administration. d) Flow cytometry results of macrophage percentage (M) were shown in gate 1. Macrophages were stained with CD11b⁺F4/80⁺. M2‐like macrophages were stained with CD11b⁺F4/80⁺CD206⁺ and CCR2⁺ macrophages was stained with CD11b⁺F4/80⁺CCR2⁺. e) Quantitative analysis of results from figure (d) in different time points. N = 4.
