Article Title: Effect of Flavonoids on MCP-1 Expression in Human Coronary Artery Endothelial Cells and Impact on MCP-1-Dependent Migration of Human Monocytes.

doi: 10.3390/ijms242216047

Figure Lengend Snippet: Figure 7. Effect of recombinant MCP-1 (A) and a neutralizing antibody (nab) directed against MCP-1 (B) on monocyte migration. Migration of THP-1 cells was determined with Boyden chamber assay toward increasing MCP-1 concentrations (A) or toward CM from HCAEC (B). In (A), medium containing recombinant MCP-1 added to the lower chamber was used to induce monocyte migration. In (B), CM from HCAEC previously treated with IL-1β or vehicle for 24 h was incubated with MCP-1 antibody (1 µg/mL) or the appropriate isotype control IgG2B (1 µg/mL) for 1 h after removal from the cells. Thereafter, migration of THP-1 monocytes toward CM was initiated. In both settings (A,B), migration was run for 6 h. Monocyte migration toward vehicle-containing medium (A) or toward CM of IL-1β-treated HCAEC containing IgG2B (B) were set to 100%. Data are presented as means ± SEM of n = 5–6 (A) or n = 6 (B) of three independent experiments each. ** p ≤0.01, *** p ≤0.001 vs. vehicle control; one-way ANOVA with Dunnett’s post hoc test (A). *** p ≤0.001 vs. vehicle control (leftmost white bar); ### p ≤0.001 vs. IL-1β-stimulated cells; one-way ANOVA with Bonferroni’s post hoc test (B).

Article Snippet: The human/mouse Anti-UCP1 antibody (MAB6158, monoclonal Mouse IgG 2B Clone # 536435, R&D Systems) was conjugated to Alexa647 (ThermoFisher Alexa Fluor 647 antibody labeling kit A20186) and incubated with adipocytes at 1:300 for 1 h. Mouse IgG2B Alexa Fluor 647-conjugated Isotype Control antibody (R&D systems) was used as a control.

Article Title: Phenotypically distinct anti-insulin B cells repopulate pancreatic islets after anti-CD20 treatment in NOD mice

doi: 10.1007/s00125-019-04974-y

Figure Lengend Snippet: Anti-insulin B cells repopulate pancreatic islets more rapidly than insulin-negative B cells after anti-CD20 treatment. Groups of VH125.hCD20/NOD mice, aged 6–8 weeks old, were injected with 2H7 anti-CD20 or IgG isotype control. Spleen, PLNs and pancreatic islets were analysed for insulin-positive and insulin-negative B cells at 8 weeks and 12 weeks post depletion by flow cytometry. ( a – f ) No. of cells from IgG control-treated (black circles) and 2H7-treated (grey squares) mice for insulin-negative B cells ( a – c ) and insulin-positive B cells ( d – f ) from spleen ( a , d ) PLNs ( b , e ) and islets ( c , f ). ( g – i ) Percentage of B cells repopulated at 8 and 12 weeks after treatment from spleen ( g ), PLNs ( h ) and islets ( i ) of mice shown in ( a – f ). Percentages were calculated as individual numbers from each 2H7-treated mouse / mean number from all IgG control antibody-treated mice. Horizontal lines represent the median value. Data represent three independent experiments. At 8 weeks, n = 7 (spleen), n = 7 (PLNs) and n = 9 (islets) for control IgG-treated mice and n = 10 (spleen), n = 9 (PLNs) and n = 12 (islets) for 2H7-treated mice. At 12 weeks, n = 8 (spleen), n = 6 (PLNs) and n = 7 (islets) for control IgG and n = 11 (spleen), n = 7 (PLNs) and n = 11 (islets) for 2H7-treated mice. * p < 0.05 (one-way ANOVA)

Article Snippet: Female VH125.hCD20/NOD mice, 6–8 weeks of age were chosen at random to receive either anti-hCD20 antibody (clone 2H7; Bio-XCell, West Lebanon, NH, USA) or control IgG2b antibody (clone MPC-11; Bio-XCell [ , , ]), as described previously [ ].

doi: 10.1007/s00125-019-04974-y

Figure Lengend Snippet: CD138 int anti-insulin B cells are enriched in pancreatic islets after anti-CD20 treatment. Groups of 6- to 8-week-old VH125.hCD20/NOD mice were injected with 2H7 anti-CD20 or IgG isotype control. Groups of mice ( n = 2 or 3 per group) were pooled and insulin + B cells from pancreatic islets were analysed for four different populations based on CD138 expression: CD138 − (blue); CD138 int IgM + (orange); CD138 int IgM lo (grey) and CD138 hi IgM lo (red). ( a , b ) Representative flow plots showing gating on live CD3 − CD11b − CD11c − ( a ) and graph showing the overall percentages of the four different populations ( b ). ( c , d ) Representative flow plots showing insulin − CD19 + , insulin + CD19 + and insulin + CD19 − cells ( c ) and graph showing the overall percentages of these cells ( d ); 2H7 (black circles), IgG (grey circles). ( e ) Representative flow plots showing CD138 and IgM expression in insulin + CD19 + and insulin + CD19 − cells. ( f , g ) Graphs showing CD138 and IgM populations on insulin + CD19 + ( f ) and insulin + CD19 − cells ( g ) ( n = 5 groups for control IgG treatment; n = 4 groups for 2H7 treatment). Horizontal lines represent the median values. Data represent two independent experiments. * p < 0.05 (one-way ANOVA)
