Furthermore, OxPCs may contribute to asthma pathobiology by promoting airway narrowing and inducing a pro-inflammatory phenotype and contraction of airway smooth muscle. OxPCs represent a potential novel target for treating oxidative stress-associated pathobiology in asthma.Unique profiles of oxidised phospholipids in the human lung correlate with airway pathophysiology. They are novel pro-inflammatory mediators with direct effects in structural cells via complex pathways, and are not targeted by standard asthma therapies. https://bit.ly/34UO2AL}, issn = {0903-1936}, URL = {//www.qdcxjkg.com/content/57/2/2000839}, eprint = {//www.qdcxjkg.com/content/57/2/2000839.full.pdf}, journal = {European Respiratory Journal} }
