Macrophage-induced neutrophil apoptosis.
Macrophages (Mphi) contribute to the resolution of early inflammation by recognizing and ingesting apoptotic polymorphonuclear neutrophils (PMN). In addition, experiments reported here demonstrated that Mphi can actively induce PMN apoptosis. Coculture of cells from 2- or 5-day-old wounds in rats, or of Mphi purified from such preparations, with PMN-rich wound cell populations obtained 1 day af...
متن کاملNeutrophil elastase-induced elastin degradation mediates macrophage
23 Neutrophil (PMNL) influx precedes lung macrophage (LM) influx into the lung following 24 exposure of newborn pups to 60% O2. We hypothesized that PMNL were responsible for the 25 signals leading to LM influx. This was confirmed when inhibition of PMNL influx with a CXC 26 chemokine receptor-2 antagonist, SB-265610, also prevented the 60% O2-dependent LM influx, 27 LM-derived nitrotyrosine fo...
متن کاملMycobacterium tuberculosis-induced neutrophil ectosomes decrease macrophage activation.
BACKGROUND The existence of ectosome-like microvesicles released by neutrophils was proposed a few decades ago. Other studies revealed that the innate immune response during mycobacterial infection is accompanied by an intense migration of neutrophils to the site of infection, which may be important during the acute phase of tuberculosis. We found that the ectosomes derived from infected neutro...
متن کاملNeutrophil apoptosis during experimentally induced Staphylococcus aureus mastitis.
The objective of this study was to determine whether neutrophil apoptosis and their consequent elimination by macrophages from the mammary gland is modulated by an infection caused by Staphylococcus aureus (S. aureus). The study was performed on twenty mammary glands of 5 virgin heifers. A buffered physiological solution (PBS) was administered as a means of control into the mammary glands of th...
متن کاملRoscovitine ameliorates endotoxin-induced uveitis through neutrophil apoptosis
Neutrophils have been recognized as critical response cells during the pathogenesis of endotoxin‑induced uveitis (EIU). Apoptosis of neutrophils induced by roscovitine has previously been demonstrated to ameliorate inflammation in several in vivo models. The present study aimed to assess whether roscovitine ameliorates EIU. EIU was induced in female C57BL/6 mice by a single intravitreal injecti...
