Stimulation of TNF-α production in RAW 264.7 mousemacrophages by lipoprotein-enriched cell membrane fractions of E. faecaliswild type and ΔbgsA.RAW264.7 cells were incubated with lipoproteinenriched Triton X-114 extracts from total membrane protein fractions derived from the indicated E. faecalis strains. The concentration of lipoprotein extracts was measured photometrically and normalized to a bacterial cfu:RAW 264.7 cell ratio of 10,000:1. At 16 h, supernatants were collected and TNF-α concentrations were quantified by ELISA. LPS at a concentration of 100 ng/ml was used as positive control. Data represent mean ± SEM of triplicates. * p < 0.001 12030 ΔbgsA versus 12030WT.
