Average rolling velocities of monocytes on IL-1β–stimulated HUVECs at a wall shear stress of 2 dynes/cm². Four-second maximization images were acquired to calculate rolling velocities of monocytes. *Statistically significant (P < .05) difference in rolling velocity as compared with control. †Statistical significance (P < .05) of anti–VLA-4 and anti-β₂ integrin treatments compared with all other treatments (n = 25-35). Monocytes from different experiments were included for rolling velocity measurements.
