HECA-452 does not block neutrophil accumulation on 4 hr. IL-1β activated HUVEC. Freshly isolated human neutrophils were untreated, treated with rat IgM or treated with 100 μg/ml HECA-452, as indicated, prior to the adhesion assay and perfused over 4 h. IL-1β activated HUVEC for 2.5 minutes. The number of adherent neutrophils was determined after the perfusion period and normalized to the area of the field of view. Shear stress = 1.5 dynes/cm2; Results shown are the average of n=3.
