Effect of blockade of p38 or MEK on MK2 activation following TLR stimulation in moDC. MoDC were pre-treated with p38 inhibitors SB203580 10 mM (S), BIRB0796 (B) 0.1 or 1.0 mM or MEK inhibitor UO126 10 mM (U) for 1hr followed by poly I:C/R848 stimulation for 30 min then Western blotted for p-MK2 with β-actin loading control.

A,IC50 of Bosutinib that block ANDV-induced EC permeability. Endothelial cells were ANDV infected, and 3 days postinfection the permeability of cells in response to VEGF addition was determined in the presence or absence of increasing amounts of kinase inhibitor. The effect of inhibitors is presented as the percentage of ANDV-induced permeability of inhibitor-treated monolayers 3 days postinfection and 30 min post-VEGF and FITC-dextran addition. B, VEGFR2-Src inhibitors block ANDV-induced permeability. Endothelial cells were plated on vitronectin-coated Transwell inserts and infected at an MOI of 0.5 in triplicate with ANDV. Three days postinfection, the permeability of ANDV- and mock-infected endothelial cell monolayers was determined as described for Fig. 1 at indicated times in the presence or absence of Bosutinib .

HBMEC were preincubated with the indicated concentrations of either ErB1/2/4 inhibitor (Pelitinib; EKB-569), and cells were then infected for 4 h with the unencapsulated strain, MC58 siaD. The numbers of adherent (black bars) and invasive (gray bars) bacteria were determined in a gentamicin protection assay. The graphs show the percentages of adhesion and invasion of inhibitor-treated cells, relative to control cells (means 盨D of three independent experiments performed in duplicate). *, P < 0.05.

Cellular senescence and SIRT1 phosphorylation was monitored in PAECs (P2) incubated in DMEM containing HDL (50 mg/L), LDL (50 mg/L), or resveratrol (100 μM) for 24 hours.

Images of typical cultures treated with the compounds and/or 500 pM BoNT/A. Cells were treated with the compounds for 30 min and then intoxicated with 500 pM BoNT/A for 4 h. Cells were then fixed and immunostained for neuron-specific b-III Tubulin (green) and Hoechst dye (nuclei; blue).

Breast cancer cells line MDA-MB-231 were treated with the indicated concentrations of ENMD-2076.

 

Dectin-1 is involved in activation of NLRP3-inflammasome by Malassezia spp. IL-1b secretion from mature human mono-DCs incubated with Syk-inhibitors (piceatannol, R406 or P505), 1 h prior to exposure to medium, MSU, b-glucan, nigericin or live M. furfur (MOI = 10) was determined after 6 h by ELISA.

Inhibition of PLCG1 phosphorylation by the silencing of DopEcR, ErGPCR, and Gq and the addition of inhibitors of RTK and Src. 5 µM SU6668 (RTK inhibitor) and 20 µM PP2 (Src inhibitor) were added to the cells for 30 min treatment before the 20E stimulation.

PP121 induces apoptosis in ATC cells. CAL62 cells were treated with PP121 at the indicated concentrations for 48 h, followed by PI staining. The nuclei were stained with Hoechst and analyzed using a fluorescent microscope. The representative images are shown.

Three days postinfection, the permeability of ANDV- and mock-infected endothelial cell monolayers was determined as described for inhibitors at indicated times in the presence or absence of the kinase inhibitor PP1. The percent change in FITC-dextran over controls is presented as a measure of EC monolayer permeability. Data are derived from two independent experiments performed in triplicate with comparable results.

WT mouse primary macrophages were untreated as control (lane 1) or treated with 0.1μg/ml E. coli LPS (lane 5-8), 10μM E-64 (lane 2 and 6), 250μM PMSF (lane 3 and 7), or 20μM MNS (lane 4 and 8).
