Description: All three steps can be reconstituted in vitro. Both P-selectin and ICAM-1 are incorporated on the wall of a flow chamber. Neutrophils are infused and begin rolling on the P-selectin. There is no interaction with ICAM-1, because the aMb2 and aLb2 integrins on the neutrophil have not been activated. Subsequently, a chemoattractant such as a bacterial N-formylated peptide (fMLP) is added to the perfusate. When it reaches the position of the rolling neutrophils in the flow chamber, it rapidly activa
