Inhibition by peptides A, B, and C of the expression of E-selectin, ICAM-1, and VCAM-1 on HUVEC preincubated with the anti-β2GPI mAbs ILA-1 (diagonal ladder column), ILA-3 (ladder column), and H-3 (spotted column), respectively. Peptide D (solid column) was used as control. Each point represents the mean ± SD of three separate experiments.
