Time course of chemotaxis and chemokinesis of neutrophils following stimulation with IL-8 or FMLP
Polymorphonuclear cells (PMNs) attend to inflammatory sites by chemotactic movement, caused by chemoattractants (CAs) like n-formyl-l-methionyl-l-leucyl-l-phenylalanine (FMLP) and interleukin-8 (IL-8).

Neutrophils in chronic lymphocytic leukemia are permanently activated and have functional defects [PDF]
A growing body of studies highlights involvement of neutrophils in cancer development and progression. Our aim was to assess the phenotypic and functional properties of circulating neutrophils from patients with chronic lymphocytic leukemia (CLL).

Dissociations in the effects of β2-adrenergic receptor agonists on cAMP formation and superoxide production in human neutrophils: support for the concept of functional selectivity. [PDF]
In neutrophils, activation of the β2-adrenergic receptor (β2AR), a Gs-coupled receptor, inhibits inflammatory responses, which could be therapeutically exploited. The aim of this study was to evaluate the effects of various β2AR ligands on adenosine-3',5'

Modulation of neutrophil chemotaxis by Aggregatibacter actinomycetemcomitans leukotoxin
Objective: Aggressive periodontitis (AgP) is frequently associated with the presence of Aggregatibacter actinomycetemcomitans, a Gram-negative pathogen, which expresses leukotoxin (Ltx) as a virulence factor.

Recruitment to the local tissue and alerted phenotype are the hallmarks of basophils in chronic urticaria (CU). Chemokine receptors such as chemokine (C-C motif) receptor 4 (CCR4) or CCR8 have been studied in skin diseases, e.g., atopic dermatitis, but ...

Lewis X antigen mediates adhesion of human breast carcinoma cells to activated endothelium. Possible involvement of the endothelial scavenger receptor C-Type lectin [PDF]
Lewis x (Lex, CD15), also known as SSEA-1 (stage specific embryonic antigen-1), is a trisaccharide with the structure Galβ(1–4)Fucα(1–3)GlcNAc, which is expressed on glycoconjugates in human polymorphonuclear granulocytes and various tumors such as colon

Differential fMet-Leu-Phe- and Platelet-activating Factor-induced Signaling Toward Ral Activation in Primary Human Neutrophils [PDF]
We have measured the activation of the small GTPase Ral in human neutrophils after stimulation with fMet- Leu-Phe (fMLP), platelet activating factor (PAF), and granulocyte macrophage-colony stimulating factor and compared it with the activation of ...

fMLP-Induced IL-8 Release Is Dependent on NADPH Oxidase in Human Neutrophils
N-Formyl-methionyl-leucyl-phenylalanine (fMLP) and platelet-activating factor (PAF) induce similar intracellular signalling profiles; but only fMLP induces interleukin-8 (IL-8) release and nicotinamide adenine dinucleotide phosphate reduced (NADPH ...
