Article Title: Pre-existing Schistosoma japonicum infection alters the immune response to Plasmodium berghei infection in C57BL/6 mice

doi: 10.1186/1475-2875-12-322

Figure Lengend Snippet: Mice in Plasmodium berghei ANKA-mono-infection group and Schistosoma japonicum-P. berghei ANKA-co-infection group were compared at different time points according to data obtained by flow cytometry. Proportion of splenic DCs subpopulation, CD11c + CD11b + and CD11c + CD45R⁄ B220 + , were analysed in A and B , with absolute number of these DCs present in C and D . Proportion of splenic CD11c + DCs expressing TLR4 , TLR9, MHC class II, and CD86 of the two groups were compared in E , F , G , H , respectively. MFI of TLR4, TLR9, MHC class II, and CD86, which were expressed on CD11c + CD11b + DCs and CD11c + CD45R⁄ B220 + DCs were present in I and J . At each time point, at least three mice per group were sacrificed. Bars represent the mean values ± SD. Student t test by comparisons between the two groups was performed with * indicating P <0.05 and # indicating P <0.01.

Article Snippet: After fixation and permeabilization using staining buffer reagents as instructed by the manufacturer, cells were incubated with biotinylated anti-mouse TLR9 (clone 5G5, Hycult Biotechnology (HBT), Uden, The Netherlands) followed by PE-conjugated streptavidin (Biolegend, San Diego, CA, USA).

Article Title: Overexpression of TLR2 and TLR9 on monocyte subsets of active rheumatoid arthritis patients contributes to enhance responsiveness to TLR agonists

doi: 10.1186/s13075-015-0901-1

Figure Lengend Snippet: Increased level of toll-like receptor 9 ( TLR9 ) on circulating and synovial monocyte subsets of rheumatoid arthritis ( RA ) patients. a Flow cytometry analysis of TLR9 expression on blood monocyte subsets from healthy controls and RA patients. TLR9 expression for synovial monocyte subsets is also shown for RA patients. TLR9 expression appears in green (P1), blue (P2) or purple (P3). Gray histograms represent internal negative controls. Data are cell populations of representative donors. b TLR9 expression on blood monocyte subsets from healthy controls and RA patients are presented as mean fluorescence intensity ( MFI ) (mean ± standard error of the mean (SEM)). Black bars healthy donors, gray bars RA patients. c TLR9 expression in the monocyte subsets of RA patient synovial fluids is presented as MFI (mean ± SEM). Striped bars RA patient synovial fluids: * p ≤0.05

Article Snippet: Enriched monocyte subsets (identified as detailed above) and neutrophils were washed twice in Hanks Balanced Salt Sodium (HBSS; Wisent) and stained with TLR2-fluorescein isothiocyanate (FITC) (TL2.1) or TLR9-FITC (5G5) antibodies (Hycult Biotech, Uden, The Netherlands).

Figure Lengend Snippet: Expression of toll-like receptor 2 ( TLR2 ) and TLR 9 in neutrophils of rheumatoid arthritis ( RA ) patients. a Flow cytometry analysis of TLR2 and TLR9 expression in neutrophils isolated from blood of healthy controls and RA patients and synovial fluids of RA patients. TLR2 and TLR9 expression is represented by red histograms whereas negative control is represented by gray histograms . Data are neutrophils of representative donors. b TLR2 and TLR9 expression on blood neutrophils from healthy controls and RA patients are presented as mean fluorescence intensity ( MFI ) (mean ± standard error of the mean (SEM)). Black bars healthy donors, gray bars RA patients . c TLR2 and TLR9 expression on synovial fluid neutrophils from RA patients are presented as MFI (mean ± SEM).

Figure Lengend Snippet: Intracellular cytokine expression in monocyte subsets from rheumatoid arthritis (RA) patients following toll-like receptor 9 (TLR9) stimulation. Mononuclear cells from RA patients and healthy donors were enriched and stimulated with CpG-2006 ( a ) and Epstein–Barr virus ( EBV ) DNA (TLR9 ligands) ( b ) in vitro. Gating strategy is described in Fig. . Intracellular cytokine level for IL-6, IL-1β, TNFα and monocyte chemoattractant protein-1 ( MCP-1 ) are shown for all three subsets of monocytes. Gray non-stimulated samples, Blue healthy donors, red RA patients. Representative cytometry histograms are representative of ten donors
