Effect of Nlac PorB on B cell proliferation. B cells from C57Bl/6 mice (black bars) and TLR2 knockout mice (white bars) were incubated for 44h with Nlac PorB or Nme PorB (10 µg/ml), LOS (100 ng/ml) or the mitogen Concanavalin A (ConA, 5 µg/ml) as previously described. Medium alone was used as a negative control. Proliferation was determined by the MTT assay as previously described. The values represent the mean of quadruplicate wells ± standard deviation and expressed as Stimulation Index (SI) as described in the text.
