Functional characterization of podia formation in normal and malignant hematopoietic cells.

abstract：:Pulmonary sequestration and activation of polymorphonuclear leukocytes (PMNLs) are characteristic of many forms of acute lung injury. The present experiments were designed to study the effects of mepacrine on human neutrophils challenged with N-formylmethionyl-leucyl-phenylalanine (fMLP). Mepacrine inhibited fMLP-indu...
