Abstract:Bronchi are exposed to particulate matter, including bacteria, fungi and dusts, that should trigger release of molecules which attract polymorphonuclear neutrophils (PMN). However, normal bronchi are relatively devoid of PMN, suggesting that there exists a mechanism to dampen acute inflammation in the lung. We have previously reported that bronchial lavage from normal humans contains a nonpolar peptide that inhibits PMN chemotaxis and oxidant production. In the present study we devised preparative methods to o… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
