PSP-induced TNF-α and IL-6 production by mouse peritoneal macrophages. B10 (TLR4+/+) and ScCr (TLR4−/−) mouse peritoneal macrophages were treated with PSP (25 μg/ml) or LPS (100 ng/ml) for 24 h. TNF-α (a) or IL-6 (b) concentration (pg/ml) in the culture supernatant was determined by ELISA. Data represent the mean ± SD of three experiments. *p < 0.05 vs. control (B10). #p < 0.05 vs. PSP (B10)
