Addition of the anti–α4 -integrin antibodies HP2/1 or HP1/2 inhibited the remaining firm adhesion in the presence of IB4. Similar results were seen with the addition of the anti-β1 antibodies K20 or LIA1/2. A control antibody was not inhibitory. *P < .05 relative to DHCB-treated neutrophils + IB4 .
