Figure Lengend Snippet: Sauchinone inhibits M1 macrophage polarization and promotes M2 macrophage polarization in BMDM. (A) The cytotoxicity of Sauchinone on BMDM was detected by CCK-8 kit. (B-G) BMDM were stimulated with LPS plus IFN-γ to induce M1 polarization in the presence or absence of different doses of Sauchinone. The transcription levels of Tnf-α , Il-6 , Il −12 , Inos , Il-1β , Cox-2 and Nlrp3 (B) were detected by RT-qPCR. TNF-α, IL-6, IL-12 and NO levels in culture supernatants (C) were measured by ELISA or Griess assay. The protein levels of p-STAT-1, STAT-1, and INOS in cell lysates (D) were detected by western blot. The percentages of INOS + , MHCⅡ + and CD86 + BMDM (E) were measured by FACS. (F-H) BMDM were stimulated with IL-4 plus IL-13 to induce M2 polarization in the presence or absence of different doses of Sauchinone. The transcription levels of Arg-1, Fizz1 , Ym-1 , Cd206 , Cd301 , and Dectin-1 (F) were detected by RT-qPCR. The protein levels of p-STAT-6 and STAT-6 in cell lysates (G) were detected by western blot. The percentages of CD301 + BMDM (H) were measured by FACS. Data were shown as Mean ± SEM from triplicate measurements. *P < 0.05, **P < 0.01 compared as indicated.
