DEXs regulated macrophage polarization via Treg cells. A Representative flow cytometry analysis images of different groups. NST, non-treated macrophages; LPS, LPS treated macrophages; IL-4/IL-13, IL-4 and IL-13 treated macrophages; DEX, macrophages co-cultured with DEXs; Treg, macrophages co-cultured with Treg cells. B–E Analysis of the proportions of iNOS⁺F4/80⁺ cells, CD206⁺F4/80⁺ cells, CD206⁺iNOS⁻ cells, iNOS⁺CD206⁻ cells in different groups. n = 3–4, *p < 0.05, **p < 0.01, ***p < 0.001
