Effector functions
- Infiltrate damaged tissue and fight pathogens
- If neutrophils do not encounter pro-inflammatory signals or signals to prolong life
- Undergo apoptosis within days of release from the bone marrow (Geering and Simon 2011)
- Neutrophils infiltrate the infected tissue by transmigration through the endothelium and epithelium
- Arriving at the site of infection - four main effector functions
- Facilitate the clearance of pathogens
- Promote further neutrophil recruitment
- Phagocytosis
- ROS production
- Degranulation
- Neutrophil granules develop sequentially in a process called granulopoiesis.
- Neutrophil extracellular trap (NET) formation
Neutrofily
- Recruitment of neutrophil to the interstitial tissue
- Release of matrix metalloproteases
- Generates N-acetyl-PGP
- Recruiting more neutrophils [23]
- Necrotic neutrophils, not cleared by macrophages
- Lyse and release DNA, protease and ROS
- Promote airway obstruction
- Remodel the airway causing a loss of lung function [23]
