Effects of TFA and FEB on macrophage polarization in vitro. (A) A WB analysis of iNOS and IL6 in RAW 264.7 cells exposed to LPS (100 ng/ml) with or without TFA (20 μg/ml) or FEB (100 nM) for 24 h. (B) A WB analysis of CD163, CD206, and ARG1 in RAW 264.7 cells exposed to LPS (100 ng/ml) with or without TFA (20 μg/ml) or FEB (100 nM) for 24 h. The data are expressed as the mean ± SD, (n = 3). * P < 0.05, ** P < 0.01. TFA, total flavones of Abelmoschus manihot; FEB, febuxostat; iNOS, inducible nitric oxide synthase; IL6, interleukin 6; LPS, lipopolysaccharide; ARG1, arginase 1; NS, not significant; WB, Western blotting.
