Perfusion of 1 µM Lovastatin (LS) with 50 μg/ml eLDL blocks eLDL-mediated altered vasoactivity (ai) (mean ± S.D., n = 4 TEBVs, Phe: phenylephrine, Ach: acetylcholine) and NO production (a-ii) in TEBVs (mean ± S.D., n = 2 from 8 TEBVs, R means recovery). b Lovastatin (1 µM) blocks the 50 U/ml TNFα mediated dysfunction of vasoactivity (i, mean ± S.D., n = 3 TEBVs, Phe: phenylephrine, Ach: acetylcholine) and NO production in TEBVs (ii, mean ± S.D., n = 2 from 8 TEBVs, R means recovery). c Lovastatin block eLDL-mediated monocyte accumulation in TEBVs (mean ± S.D., n = 4,7,5,4,4 TEBVs by two-way ANOVA). d Lovastatin inhibits ICAM-1 and E-selectin expression on endothelial cells in TEBVs (mean ± S.D., n = 5,3,4,5,3 TEBVs for VCAM-1 accordingly, n = 4,3,4,5,4 TEBVs for ICAM-1 accordingly, n = 5,3,4,4,4 TEBVs for E-Selectin accordingly, **P = 0.0097, ***P = 0.0007 by two-way ANOVA and Tukey post hoc test, MFI = mean fluorescence intensity). e Lovastatin (LS) blocks primary monocyte differentiation into macrophages, flow cytometry testing of CD80 (mean ± S.D., n = 3 independent wells from one monocyte isolations, ICAM-1: **P = 0.00016, E-Selectin: ***P < 0.0001 by Student’s t test, MFI = mean fluorescence intensity). f Lovastatin (LS) blocks primary monocytes activation, flow cytometry testing of CD36 (mean ± S.D., n = 3 independent wells, ***P < 0.0001 by Student’s t test, MFI = mean fluorescence intensity). (Flow rate: 0.5 ml/min per TEBV (0.4 Pa) for vasoactivity testing and 0.125 ml/min (0.1 Pa) for monocyte accumulation).
