Burkholderia multivorans and Burkholderia cenocepacia are the species responsible for most of the infections of cystic fibrosis patients. Lipopolysaccharide endotoxins (LPSs) are among the foremost factors of pathogenesis of Gram-negative infection and, in particular, lipid A is the endotoxic portion of LPS responsible for eliciting host innate immune response. In this work, the complete primary structure of the lipid A from B. multivorans C1576 has been defined and, further, its pro-inflammatory activity in a cystic fibrosis airways model is shown. The structure of B. multivorans lipid A was attained by chemical, mass spectrometry and nuclear magnetic resonance analyses whereas its biological activity was assessed on the intestinal epithelial cell line CACO-2 cells, on the airway epithelial IB3-1 cells, carrying the \u0394F508\/W1282X CFTR mutation and on an ex vivo model of culture explants of nasal polyps.<\/jats:p>","DOI":"10.1177\/1753425909347400","type":"journal-article","created":{"date-parts":[[2009,10,30]],"date-time":"2009-10-30T21:55:05Z","timestamp":1256939705000},"page":"354-365","source":"Crossref","is-referenced-by-count":13,"title":["The
