FIG. 5.

CXCL13 concentrations in the supernatants of monocytes preincubated either with a neutralizing TLR2 antibody (Ab) (gray bars) or with the corresponding isotype control (black bars) (both at 12.5 μg/ml) and then for 24 h with either medium, B. garinii (MOI, 2), or LPS (1 ng/ml). The asterisk indicates that the P value is <0.05 for a comparison with the isotype control. The bars indicate the means of at least three independent experiments done in duplicate, and the error bars indicate the standard errors of the means of the independent experiments.
