Description:
Cystic fibrosis (CF) patients are hypersusceptible to chronic Pseudomonas aeruginosa lung infections. Cultured human airway epithelial cells expressing the delta F508 allele of the cystic fibrosis transmembrane conductance regulator (CFTR) were defective in uptake of P. aeruginosa compared with cells expressing the wild-type allele. Pseudomonas aeruginosa lipopolysaccharide (LPS)-core oligosaccharide was identified as the bacterial ligand for epithelial cell ingestion; exogenous oligosaccharide inhibited bacterial ingestion in a neonatal mouse model, resulting in increased amounts of bacteria in the lungs. CFTR may contribute to a host-defense mechanism that is important for clearance of P. aeruginosa from the respiratory tract.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3677515/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3677515/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pier, G B -- Grout, M -- Zaidi, T S -- Olsen, J C -- Johnson, L G -- Yankaskas, J R -- Goldberg, J B -- AI22806/AI/NIAID NIH HHS/ -- AI35674/AI/NIAID NIH HHS/ -- HL42384/HL/NHLBI NIH HHS/ -- R01 HL058398/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1996 Jan 5;271(5245):64-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Channing Laboratory, Brigham and Women's Hospital, Harvard Medical School, Boston, MA 02115-5899, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8539601" target="_blank"〉PubMed〈/a〉
