Neutrophil recruitment into organs is orchestrated by tissue-resident cells. • Transendothelial migration of neutrophils is influenced by organ-specific endothelium and closely-associated cells of the vasculature. • Tissue immune and stromal cells work in concert to regulate neutrophil recruitment into the organ interstitium.

Mechanisms of Immune Complex–Mediated Neutrophil ...

May 25, 2017·Tissue-accumulated neutrophils release inflammatory mediators (eg, reactive oxygen species [ROS], proteases, eicosanoids, and cytokines) that activate resident cells. They also produce cytokines and chemokines that promote their own recruitment and the recruitment of other circulating leukocyte subsets.

Neutrophils | British Society for Immunology

Neutrophils are the first white blood cells recruited to sites of acute inflammation, in response to chemotactic cues such as CXCL8 (interleukin-8, IL-8) produced by stressed tissue cells and tissue-resident immune cells such as macrophages. Neutrophils therefore comprise a large proportion of the early cellular infiltrate in inflamed tissues ...

Crosstalk between Sentinel and Helper Macrophages ... - Cell

Ly6C − macrophages acted as tissue-resident sentinels that attracted circulating neutrophils and Ly6C + macrophages. Such Ly6C + macrophages played a previously undescribed helper role: once recruited to the site of infection, they produced the cytokine TNF, which caused Ly6C − macrophages to secrete CXCL2. This chemokine activated matrix ...

Neutrophils Function and Abnormal Results

Sep 23, 2020·Neutrophils have a very short lifespan, living on average only 8 hours,   but our bodies produce roughly 100 billion of these cells each day. After being released from the bone marrow, around half of these cells are present along the lining of blood vessels and the other half are found in tissues of the body.
