Abstract
The neutrophil is a crucial early defence against microbial infection, butneutrophilic inflammation can result in devastating acute and chronicinflammatory diseases. In the lungs, the neutrophil is a principal part of thepathology of the acute respiratory distress syndrome, and its activation mayalso be of substantial importance in chronic obstructive pulmonary disease andsome forms of asthma. Induction of neutrophil recruitment in response tomicrobial attack requires activation of TLR (Toll-like receptor)-basedsignalling pathways and the concerted actions of multiple cell types, includingsentinel cells such as monocytes and macrophages acting together with tissuecell types such as the epithelium or smooth-muscle cell. The present reviewdescribes some of these networks and the resulting potential for their targetingin respiratory disease.

PMID: 18031251 It has long been known that many cells respond to microbial stimuli such as LPS (lipopolysaccharide), lipoproteins and flagellin by the generation of neutrophil-recruiting chemokines such as IL-8 (interleukin-8).

PMID: 18031251, 9670975 Of these, LPS was thought to be a potent stimulator of neutrophil survival, acting again via IL-1beta [39], since it was apparent that LPS-activated neutrophils were themselves a source of IL-1beta, which was an effective stimulator of survival in an autocrine fashion.

PMID: 18031251, 1993838, 7504060 Such co-culture models have been employed previously to demonstrate that monocytes amplify prothrombotic responses to LPS {via production of TF (tissue factor) from endothelial cells [36]}, and can potentially enhance recruitment of other cells through the up-regulation of adhesion molecules such as VCAM (vascular cell adhesion molecule).

PMID: 18031251, 17138954 In part, this is because of a variety of physical defence measures, including the trapping of particulate matter in larger airways by mucus and the ability of various airway-secreted molecules such as surfactant proteins to bind and neutralize LPS.

PMID: 18031251, 1569186 Neutrophil proteases have the ability to further modify local responses, since they can digest CD14 and decrease LPS responsiveness of some cells, but may also generate IL-8 production from epithelial cells [55] or signal via TLR4.
