    Abstract

    Cystic fibrosis (CF) patients develop chronic airway infections with Pseudomonas aeruginosa (PA). Pseudomonas aeruginosa synthesized lipopolysaccharide (LPS) with a variety of penta- and hexa-acylated lipid A structures under different environmental conditions. CF patient PA synthesized LPS with specific lipid A structures indicating unique recognition of the CF airway environment. CF-specific lipid A forms containing palmitate and aminoarabinose were associated with resistance to cationic antimicrobial peptides and increased inflammatory responses, indicating that they are likely to be involved in airway disease.

      • Related Citations
        Calculated set of PubMed citations closely related to the selected article(s) retrieved using a word weight algorithm. Related articles are displayed in ranked order from most to least relevant, with the “linked from” citation displayed first.
      • Compound (MeSH Keyword)
        PubChem chemical compound records that are classified under the same Medical Subject Headings (MeSH) controlled vocabulary as the current articles.
      • Gene (OMIM)
        Gene records associated with Online Mendelian Inheritance in Man (OMIM) records that cite the current articles in their reference lists.
      • Nucleotide (Weighted)
        Nucleotide records associated with the current articles through the Gene database. These are the related sequences on the Gene record that are added manually by NCBI.
      • OMIM (calculated)
        Online Mendelian Inheritance in Man (OMIM) records that include the current articles as references in the light bulb links within or in the citations at the end of the OMIM record. The references available through the light bulb link are collected using the PubMed related articles algorithm to identify records with similar terminology to the OMIM record.
      • OMIM (cited)
        Online Mendelian Inheritance in Man (OMIM) records that include the current articles as reference cited at the end of the OMIM record.
      • Protein (Weighted)
        Protein records associated with the current articles through related Gene database records. These are the related sequences on the Gene record that are added manually by NCBI.
      • Protein Clusters
        Clusters of related proteins from the Protein Clusters database that cite the current articles. Sources of references in Protein Clusters include the associated Gene and Conserved Domain records as well as NCBI added citations.
      • Substance (MeSH Keyword)
        PubChem chemical substance (submitted) records that are classified under the same Medical Subject Headings (MeSH) controlled vocabulary as the current articles.
