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

The release of polymorphonuclear leukocyte proteinases in buffy-coat-depleted red cell concentrates was examined during a storage period of 35 days. Collagenase, gelatinase and elastase predominantly induce breakdown of connective tissue. However, when released by cell disintegration during red cell concentrate

Alterations in neutrophil functions by tobacco components may play a pivotal role in pulmonary emphysema. This study examined the role of nicotine in altering F-actin formation and calcium (Ca2+) release (two early events in neutrophil motility). The effects of these

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

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.
