Figure Lengend Snippet: CCL5 directly regulates macrophage polarization. Mouse peritoneal macrophages (PMφ) and bone marrow-derived macrophages (BMMφ) were stimulated with 100 ng/ml rmCCL5 for 6 h, and the expression of M1 macrophage markers (iNOS, IL-1β, and TNFα) was detected by qPCR in PMφ (a) and BMMφ (b). PMφ and BMMφ were stimulated with 20 ng/ml IL4 and with or without 100 ng/ml rmCCL5 for 6 h, and the expression of M2 macrophage markers (Arg1, Ym1, and CD206) was detected by qPCR in PMφ (c) and BMMφ (d). PMφ and BMMφ were stimulated with 20 ng/ml IL4 and with or without 100 ng/ml rmCCL5 for 24 h, and the expression of M2 macrophage markers (Arg1, Ym1, and CD206) was detected by western blot analysis in PMφ (e) and BMMφ (f).
