FIG. 3.

CXCL13 concentrations in the supernatants of monocytes incubated with bacteria (B. garinii, T. pallidum, or S. pneumoniae) in vitro. The bars indicate the means of three independent experiments done in duplicate, and the error bars indicate the standard errors of the means of the independent experiments. Two asterisks indicate that the P value is ≤0.01 for comparisons with the unstimulated control (unstim.) and equal concentrations of T. pallidum and S. pneumoniae; one asterisk indicates that the P value is ≤0.01 for comparisons with the unstimulated control and an equal concentration of S. pneumoniae.
