BAI reduces the production of IL-6 and TNF-α from HK-MRSA-stimulated peritoneal Mϕs and iBMDMs. Primary peritoneal Mϕs (3.5 × 10⁵/well) and iBMDMs (2 × 10⁵/well) were seeded into plates and incubated overnight respectively. Cells were administrated with different concentrations of BAI for 12 or 24 h with the stimulation of HK-MRSA (MOI = 10). The secretion of IL-6 and TNF-α was detected in the supernatants of primary peritoneal Mϕs (A, B) or iBMDMs (C, D). Values were means of 3 replicate determinations (n = 3) ± sd. Statistical significance was determined at ^*P < 0.05; ^**P < 0.01; and ^***P < 0.001
