Antifluorescein antibody molecules were used to interrupt the stimulation of neutrophils by a fluoresceinated chemotactic peptide. From the results we construct a semiquantitative relationship among ligand-receptor interaction, the time course of cell triggering and response, and aspects of cellular adaptation.

Binding of chemoattractant to polymorphonuclear leukocytes (PMNL) triggers a series of events like polymerization of actin and tubulin, orientation of cells, chemotaxis, increase in fluid pinocytosis and phagocytosis, and stimulation of microbicidal pathways which includes lysosomal degranulation and generation of

To define a possible role of the enzyme phosphatidylinositol 3-kinase (PI 3-kinase) in motile functions of neutrophils, we have used a potent inhibitor of this enzyme, [1S-(1alpha,6b alpha,9a beta,11alpha,11bbeta)]-1-(acetyloxy)-1,6b,7,8,9a,10,11 ,11b-octahydro-1-(methoxymethyl)-9a,11b-dimethyl-3H-furo[4,3,2-de]indeno [4,5-h]-2-benzopyran-3,6,9-trione (wortmannin). Wortmannin markedly attenuated chemotactic peptide-induced development of polarity

The formyl peptide chemotactic receptor has been solubilized by digitonin treatment of purified human neutrophil membranes. Of several potential assay methods tested for their ability to separate receptor-bound from free ligand, only gel filtration through an acrylamide cross-linked agarose matrix

A potent chemotactic peptide, formyl-norleucyl-leucyl-phenylalanyl-norleucyl-tyrosyl-lysine was derivatized by reaction with N-succinimidyl 4-fluorobenzoate. This derivatized peptide bound to human polymorphonuclear leukocytes in vitro and exhibited biological activity in a superoxide production assay. Peptide labeling using N-succinimidyl 4-[18F]fluorobenzoate was accomplished in reasonable
