Figure Lengend Snippet: 2LZONA-5 reduced the expression of HLA-DR in IFN-γ-stimulated HUVEC, while it did not impact the expression of HLA variants and the viability of IFN-γ-stimulated human macrophages. ( A ) The expression level of HLA-DR was assessed in HUVEC either left untreated as a control (Ct.) (white histogram), or treated with 20 ng/mL IFN-γ (red histogram). ( B ) Interferon-γ-stimulated HUVEC were treated with either the Veh. (gray histogram) or 2LZONA-5 (purple histogram) for 48 h. In ( A ) the results are expressed as the mean MFI ± S.D. for n = 3 replicates per condition and in ( B ), the results are normalized and expressed as the mean percentage ± S.D. of the Veh. conditions, the latter being set at 100%. ( C-E ) The expression level of HLA-DP, HLA-DQ and HLA-DR was assessed in human M1 macrophages treated for six days with 20 ng/mL IFN-γ, in the presence of either the Veh. (gray histogram) or 2LZONA-5 (purple histogram). The measures were done in triplicate, for n = 4 healthy donors (#1, #2, #3, and #4), and the results are normalized and expressed as the mean percentage ± S.E.M. of the Veh. conditions, the latter being set at 100%. ( F ) The cell viability has been appraised by flow cytometry after six days of treatment in the presence of 20 ng/mL IFN-γ added with either the Veh. or 2LZONA-5. The results are presented as the mean percentage of live cells/ total cells ± S.E.M. obtained for the four tested donor. The measures were done in triplicate for each donor. In ( B-F ), the dotted lines are drawn to highlight the effect of 2LZONA-5 compared with the Veh. In ( C ) the results are expressed as the mean MFI ± S.E.M for n = 4 donors (#1, #2, #3 and #4), each measure having been done in triplicate.
Article Snippet: As a previously published method, , human umbilical vascular endothelial cells (HUVEC) (passage 5) were purchased from PromoCell (PromoCell, Heidelberg, Germany) as a pool from n = 6 donors and were grown in endothelial cell growth medium (ECBM) media (PromoCell), added with 2% fetal bovine serum (FBS) (PAN-Biotech GmbH, ref: #P170201, Aidenbach, Germany).
