Although many of the receptors mediating neutrophil (polymorphonuclear leukocyte (PMN)) adhesion to extracellular matrix (ECM) proteins have been identified, the signal transduction pathways leading to cell spreading are not clearly defined. Studies

In FMLP-activated polymorphonuclear leukocytes (PMNs) challenged with IgG-opsonized erythrocytes (EIgG), the termination of phagocytosis correlates with an accumulation of ceramide, a product of sphingolipid metabolism. Furthermore, the exogenous add

Thrombospondin (TSP), a multifunctional homotrimeric glycoprotein of approximately 450,000 M(r), is a component of the extracellular matrix that mediates the adhesive interactions of several different cell types including hematopoietic progenitor cel

Differentiation of the human promyelocytic leukemia cell line HL-60 to polymorphonuclear leukocyte (PMN)-like cells with DMSO provides an important model for studying the acquisition of PMN functional responses that accompany differentiation. We show

Chemoattractant-induced activation of human polymorphonuclear leukocytes involves receptor coupling to guanine nucleotide binding proteins (G-proteins). Treatment of polymorphonuclear leukocytes with pertussis toxin, which ADP-ribosylates neutrophil

The extracellular matrix (ECM) protein thrombospondin (TSP) binds specifically to polymorphonuclear leucocyte (PMN) surface receptors and promotes cell adhesion and motility. TSP receptor expression increases 30-fold after activation with the synthet

Thrombospondin (TSP), a 450-kDa extracellular matrix protein secreted by platelets may be instrumental in triggering polymorphonuclear leukocyte (PMN) activation and mediating PMN-endothelial cell interactions. TSP alone had no effect on O-2 generati

Thrombospondin (TSP), a 450-kDa trimeric glycoprotein secreted by platelets and endothelial cells at sites of tissue injury or inflammation, may play an important role in polymorphonuclear leukocyte (PMN) adherence to blood vessel walls before diaped

We have identified two major proteins in human neutrophils that are phosphorylated in vitro by protein kinase C (PKC) as lipocortins III and a fragment of a lipocortin-like 68-kDa protein. In electroporated cells, the 68-kDa protein was phosphorylate

The sphingomyelin cycle, which plays an important role in regulation of cell growth, differentiation, and apoptosis, involves the formation of ceramide by the action of a membrane-associated, Mg2+-dependent, neutral sphingomyelinase and/or a lysosoma
