Figure Lengend Snippet: Endothelial P2Y 6 R activation failed to increase monocyte adhesion during schistosomiasis. A. Monocyte adhesion induced by UDP 100 µM was blocked by the selective P2Y 6 R antagonist (MRS2578 1 µM) in the control group (white bars). B. UDP 100 µM stimulus did not increase monocyte adhesion in the infected group (gray bars). ARL67156 100 µM = ectonucleotidase inhibitor (added 30 min before). Data were expressed as mean and SEM of n independent experiments performed in triplicate for each condition. ***p < 0.001 (One-way ANOVA followed by Tukey’s multiple comparisons test, n = 4 animals for each group)

Article Snippet: After that, cells were washed twice for 5 min with Triton X-100 0.2% diluted in PBS and incubated with anti-rabbit P2Y 6 R polyclonal antibody (1:500, Alomone Labs, Israel) overnight.

Techniques: Activation Assay, Control, Infection

Figure Lengend Snippet: Endothelial P2Y 6 R mRNA and protein levels are reduced during schistosomiasis. A. Immunocytochemistry staining of cultured mesenteric endothelial cells from control (top line) and infected (bottom line) groups using anti-P2Y 6 R antibody (1:500, overnight), followed by Alexa Fluor 488 secondary antibody (1:300, 1 h, green) and nuclear fluorescence using DAPI (blue) (scale bar = 20 μm; × 400) (see methods). B. The fluorescence intensity was quantified and then expressed as arbitrary units (a.u.). P2Y 6 R mRNA levels were lower in the infected (gray bars) than in the control (white bars) group. C. The P2Y 6 R mRNA levels were normalized by the endogenous gene β-actin. Data were expressed as mean and SEM of n independent cultures performed with different animals for each condition. ***p < 0.001, **p < 0.01 (unpaired t -test, n = 3–4 animals for each group)

Figure Lengend Snippet: Endothelial P2Y 6 R downregulation is mediated by proteosome degradation during schistosomiasis. A. Treatment with the ectonucleotidase inhibitor ( ARL67156 100 µM, 24 h) followed by a wash step and UDP 100 µM (5 h); treatment with apyrase 2 U/L (24 h) followed by washing and UDP 100 µM (5 h). B. Treatment with the proteosome inhibitor MG132 (1 µM, 1 h) followed by UDP (100 µM, 5 h). Data were expressed as mean and SEM of n independent cultures in triplicate for each condition. ***p < 0.001, *p < 0.05 (One-way ANOVA followed by Tukey’s multiple comparisons test, n = 3 animals for each group). ARL = ARL67156

Figure Lengend Snippet: Endothelial P2Y 6 R expression is increased by proteosome inhibition during schistosomiasis. A. Immunocytochemistry staining of cultured mesenteric endothelial cells from basal (top line) MG132 1 µM, 1 h (middle line) or MG132 1 µM, 6 h (bottom line) using anti-P2Y 6 R antibody (1:500, overnight) followed by Alexa Fluor 488 secondary antibody secondary antibody (1:300, 1 h, green) and nuclear fluorescence using DAPI (blue) (scale bar = 20 μm; × 400) (see methods). B. The fluorescence intensity was quantified for all groups and then expressed as arbitrary units (a.u.). C . ROS was quantified colorimetrically using NBT. D . Lipid peroxidation was quantified by the production of malondialdehyde (MDA) in reaction with thiobarbituric acid. Data were expressed as the mean and SEM of n independent cultures in triplicate for each condition. **p < 0.01 ( B , One-way ANOVA followed by Tukey’s multiple comparisons test, n = 3 animals for each group); ***p < 0.001; **p < 0.01 (C, D, unpaired t -test, n = 3 animals for each group).

Figure Lengend Snippet: Proposed mechanism of proteasomal-dependent P2Y 6 receptor downregulation pathway in mesenteric endothelial cells in a preclinical model of intestinal schistosomiasis. The mesenteric endothelial cells primed by infection showed a proteasome-dependent P2Y 6 receptor downregulation under conditions of oxidative stress (1) triggering post-translational modifications protein such as polyubiquitination (2), which targets the receptor to the proteasomal degradation pathway (3–4), ultimately resulting in reduced endothelial P2Y 6 R expression and diminished proinflammatory effect (5)
