Fig 6. S100A8/A9 inhibits bacterial growth of S. Typhimurium and S. Typhi in vitro.

Fig 6

Growth of S. Typhimurium (14028; A) and S. Typhi (Vivotif, Crucell; B) was assessed for a maximum of 24 hours in the presence of recombinant S100A8/A9 (50 μg/ml; grey bars) or control (white bars). Bacterial growth was dose dependently inhibited by S100A8/A9. Growth arrested, CFSE-labelled heat-inactivated S. Typhimurium bacteria were incubated with peripheral blood neutrophils (C) from wildtype (WT; white) and S100A9 -/- mice (grey) (n = 4 per mouse strain) for 0, 15 and 60 minutes respectively after which phagocytosis was quantified (see Methods). Data are expressed, as mean ± SD. **** P<0.0001, determined via non-parametric t tests comparing different dosages per time point.
