| pathogen and autoantigen homologous regions within the cystic fibrosis transmembrane conductance regulator (cftr) protein suggest an autoimmune treatable component of cystic fibrosis. | the cystic fibrosis transmembrane conductance regulator (cftr) chloride channel provides the glutathione and hypochlorous acid necessary for bactericidal/viricidal actions. cftr mutations block these effects, diminishing pathogen defence and allowing extracellular pathogen accumulation, where antibody encounter is likely. kegg pathway analysis of the cftr interactome shows that cftr is involved in pathogen entry pathways and immune defence as well as in pathways relevant to comorbid conditions ( ... | 2011 | 21496124 |

| intragenomic and intraspecific heterogeneity of the 16s rrna gene in seven bacterial species from the respiratory tract of cystic fibrosis patients assessed by pcr-temporal temperature gel electrophoresis. | 16s rrna gene-based cultivation-independent methods are increasingly used to study the diversity of microbiota during health and disease. one bias of these methods is the variability of 16s rrna gene that may exist among strains of a same species (intraspecific heterogeneity) or between rrs copies in a genome (intragenomic heterogeneity). we evaluated the level of intraspecific and intragenomic 16s rdna variability in seven species frequently encountered in respiratory tract samples in cystic fi ... | 2011 | 21621347 |
| a novel highly charged exopolysaccharide produced by two strains of stenotrophomonas maltophilia recovered from patients with cystic fibrosis. | stenotrophomonas maltophilia is a non-fermenting gram-negative microorganism capable of causing chronic pulmonary infection in cystic fibrosis patients and its ability to form biofilms on polystyrene and glass surfaces, as well as on cystic fibrosis-derived bronchial epithelial ib3-i cells was recently demonstrated. the latter evidence might explain the power of s. maltophilia to produce persistent lung infections, despite intensive antibiotic treatment. in addition to being important components ... | 2011 | 21636078 |
