Leukocyte rolling in TNFα-stimulated venules.

Leukocyte rolling was observed in venules stimulated for 2.5 hours with TNFα. Rolling before and after E-selectin mAb (10E6, 10 μg), E-selectin mAb plus P-selectin mAb (RB40.34, 10 μg), or antineutrophil mAb (RB6-8C5) were quantified and data are presented as mean ± SE. **Denotes significant difference (P < .01) from no mAb.
