Figure Lengend Snippet: KFDV infection of HDMECs leads to their activation. a HDMECs were infected with KFDV at an MOI of 10. Mock-infected HDMECs were exposed to the same dose of UV-inactivated KFDV. At 24 and 48 h p.i., mRNA expression of E-selectin, ICAM1, and VCAM1 was analyzed by qRT-PCR and normalized to the expression of housekeeping genes. Fold increase indicates differences in normalized mRNA expression relative to expression in noninfected cells. b Flow cytometry was used to measure the protein levels of E-selectin, VCAM1, and ICAM1 expression in the KFDV-infected HDMECs at 48 h p.i. The production of cell-adhesion molecules is shown in overlapping histograms of relative fluoresce intensity in the analyzed cells; empty histograms with solid lines represent mock-infected (UV-inactivated virus) HDMECs, and gray histograms represent the KFDV-infected cells. c HDMECs were treated with TNF-α (positive control) or mock-infected with UV-inactivated KFDV or infected with KFDV at an MOI of 10 and incubated for 24 and 48 h. After incubation, the adhesion of BCECF–stained leukocytes was measured as described in the Materials and Methods. The leukocyte adhesion index represents the fold change relative to controls (y-axis). d HDMECs grown and fixed on slides at 48 h p.i. were stained with anti-flavivirus envelope (green) and anti-occludin (red) or anti-ZO-1 antibodies and counterstained with DAPI (blue). Bar = 20 µm. e Total RNA from uninfected, mock- and KFDV-infected HDMECs 48 h p.i. was used to determine the fold change in occludin and ZO-1 mRNA expression by qRT-PCR. * p

Figure Lengend Snippet: PMN rolling and adhesion on Bartonella- exposed HUVEC under flow at a shear rate of 1 dyne/cm 2 . Bacteria were centrifuged on endothelial cells in four-well plates containing rectangular coverslips. After 8 h coverslips were processed for a laminar-flow adhesion assay. PMN (3 × 10 6 per ml) were injected into the flow system and perfused over endothelial cell monolayers for 5 min using a high-precision syringe pump. When indicated, cells were preincubated with Abs against E-selectin, ICAM-1, or VCAM-1 120 min before measurement. TNF-α (20 ng/ml) was used as a positive control. Rolling PMN (for a definition see Materials and Methods) were counted over a 3-min observation period. Adherent PMN were determined by counting 10 to 12 random high-power fields (see Materials and Methods). B. henselae Berlin-1 was almost as effective as TNF-α. Note that PMN rolling and adhesion were almost completely blocked by an anti-E-selectin MAb. Data are means ± standard errors of the means of three separate experiments.

Figure Lengend Snippet: (a) B. henselae- induced translocation of transcription factor NF-κB in HUVEC. An EMSA using a 32 P-labeled double-stranded NF-κB consensus oligonucleotide was performed. Nuclear proteins were extracted 10 to 180 min p.i. TNF-α was used as a positive control. Note biphasic NF-κB translocation in B. henselae- exposed HUVEC. Moreover, note the undiminished NF-κB signal in HUVEC treated with heat-inactivated polymyxin B (50 μg/ml)-exposed bacteria (right lane), suggesting that living bacteria and LPS are not central to NF-κB-translocation. A representative gel (of five independent experiments) is shown. (b) NF-κB upregulation was detected even at 72 h p.i. (c) Control experiments with a 2- to 20-fold molar excess of an NF-κB consensus oligonucleotide clearly demonstrate the specificity of the shift. (d) B. henselae- induced E-selectin and ICAM-1 expression was dose dependently reduced by NF-κB-specific inhibitor CAPE, as demonstrated by cell surface ELISA.

Figure Lengend Snippet: (a) OMP-induced endothelial adhesion molecule expression was NF-κB dependent and unrelated to LPS. Effects of OMPs (500 ng/ml) on E-selectin and ICAM-1 expression were compared to those for untreated cells. When indicated, cells were pretreated with 5 or 25 μM CAPE 1 h before exposure to OMPs; this resulted in a dose-dependent reduction of adhesion molecule expression. When indicated, polymyxin B was added to OMPs or LPS in a concentration of 50 μg/ml. Data are means ± standard errors of the means of three separate experiments. (b) OMP induced translocation of transcription factor NF-κB in HUVEC. An EMSA was performed as described in Materials and Methods. Nuclear proteins were extracted 40 min p.i. TNF-α was used as a positive control. Note the weak NF-κB signal in LPS-exposed HUVEC compared to that for OMP-treated cells. A representative gel (from three independent experiments) is shown.

doi: 10.1155/2013/617809

Figure Lengend Snippet: Del-1 inhibits ICAM-1-dependent chemokine production by neutrophils. (a)–(c) ATRA-differentiated HL-60 neutrophils were cultured for 24 hours on plates coated with Fc protein control, ICAM-1-Fc, or Del-1-Fc, and induction of release of CCL3 (a), CXCL2 (b), and TNF (c) was assayed by ELISA. (d)-(e) ATRA-differentiated HL-60 neutrophils were cultured for 24 hours on ICAM-1-Fc-coated plates in the presence of the indicated concentrations of soluble Del-1, and induction of release of CCL3 (d) and CXCL2 (e) was assayed by ELISA. (f)-(g) ATRA-differentiated HL-60 neutrophils were stimulated for 24 hours with 1 μ g/mL Pam 3 CSK 4 or 0.1 μ g/mL LPS, in the absence or presence of the indicated concentrations of Del-1, and induction of release of CCL3 (f) and CXCL2 (g) was assayed by ELISA. Data are means ± SD ((a)–(e), n ≥ 4 and (f)-(g), n = 2 sets of HL-60 cells). * P

Figure Lengend Snippet: Regulation of Del-1 versus ICAM-1 and VCAM-1 by inflammatory stimuli. HUVEC were cultured for the indicated time intervals with 10 ng/mL TNF (a), 5 μ g/mL serum amyloid A (SAA; (b)), P. gingivalis (Pg; MOI = 10 : 1) (c), Pam 3 CSK 4 or LPS (both at 0.5 μ g/mL; (d)), 10 ng/mL IFN γ (e), or IL-17A or IL-17F (both at 10 ng/mL; (f)) and assayed for Del-1, ICAM-1, and VCAM-1 mRNA expression. Results were normalized to those of GAPDH mRNA and expressed as fold change in transcript levels relative to those of medium-treated cells at 2 hours (HRS), the average value of which was taken as 1. The medium-treated groups in (b) and (c) are the same (SAA and Pg were tested together but were separated in the graphs for enhanced clarity). Data are means ± SD of duplicate determinations from one of three independent sets of experiments that yielded similar results.

Figure Lengend Snippet: Expression of endothelial adhesion molecules in Del-1 deficiency. (a) Gingiva dissected from 16-week-old C57BL/6 Edil 3 +/+ (WT) and Edil 3 −/− mice were processed for quantitative real-time PCR analysis of mRNA expression of the indicated genes; results were normalized to those of GAPDH mRNA and expressed as fold change in Edil 3 −/− transcript levels relative to WT, the average value of which was taken as 1. (b) Sagittal sections of interdental gingiva from 16-week-old C57BL/6 WT or Edil 3 −/− mice were stained for ICAM-1, VCAM-1, or E-selectin and CD31, as indicated. Shown are representative overlays of differential interference contrast and fluorescent confocal images, with colocalization demonstrated in merged images (scale bar, 50 μ m). (c) The fluorescence intensities of the images shown here and of additional representative images from independent mice (5 per group) were quantified using ImageJ analysis. In (a) and (c), data are means ± SD ( n = 5 mice per group). No statistically significant differences were detected between Edil 3 −/− and WT littermate controls.
