Fig. 8. FimH induces human peripheral blood DC (PBDC) activation.

Fig. 8

Peripheral blood mononuclear cells (PBMCs) were treated with 5 μg per ml of FimH and 2 μg per ml of LPS for 24 h. a The distinctness of the PBDCs from the PBMCs is shown. The lineage markers included CD3, CD14, CD16, CD19, CD20, and CD56. b The expression levels of costimulatory molecules and MHC classes I and II in BDCA1+ (upper panel) and BDCA3+ DCs (lower panel) are shown. (n = 4 donors, one-way ANOVA, mean ± SEM). c Syngeneic CD4 T cell proliferation and IFN-γ production were measured after co-cultured with stimulated BDCA1+ DCs and T cells. d PBMCs were pre-treated with 20 μM MD2 inhibitors for 30 min and subsequently treated with FimH and LPS. The expression of costimulatory molecules and MHC class I and II in BDCA1+ (upper panel) and BDCA3+ DCs (lower panel) are shown. (n = 4 donors, one-way ANOVA, mean ± SEM).
