Effects of antibodies against different adhesion molecules on adhesion of PV RBCs to HUVECs under static conditions. (A) When incubated with HUVECs, neither anti-Lu/BCAM anti-α₂, anti-α₅, α₆, β₁, α_vβ₃ integrins, nor anti-RAGE antibodies modified adhesion of RBCs (n = 10). In contrast, anti-α₅ chain laminin and to a lesser extent anti-α₃ integrins significantly reduced adhesion (**P < .01; *P < .05; n = 10). (B) Monoclonal or polyclonal anti-Lu/BCAM incubated with RBCs inhibited the adhesion of HUVECs measured in static conditions (**P < .01; *:P < .05, respectively; n = 10), while anti-ICAM-4 or control mAb anti-CD59 had no significant effect on adhesion (n = 5).
