Development of antibacterial antibodies for cystic fibrosis patients
 Vašková, Michaela ; Hodek, Petr (advisor) ; Nosková, Libuše (referee)
Cystic fibrosis (CF) is an autosomal recessive disease caused by mutations in the CFTR gene (CF transmembrane conductance regulator). These mutations result in absent or defective CFTR chloride channel function. The susceptibility to bacterial respiratory infections due to the accumulation of thickened mucus and altered glycosylation in lungs is typical for this disease. Bacteria Pseudomonas aeruginosa (PA) is a major cause of these infections. Among other virulent factors, the pathogenicity of these bacteria is caused by fucose-specific PA-IIL lectin which plays a role as an adhesin. The effect of anti-PA-IIL egg yolk antibodies and multivalent fucose-based PA-IIL inhibitors on PA adherence to lung epithelial cells was studied in this work. Chicken antibodies were isolated from egg yolks before and after immunization with antigen PA-IIL. Specific anti-PA-IIL antibodies were obtained by affinity chromatography using a column with an immobilized PA-IIL. Reactivity of IgY was verified by ELISA. The presence of PA-IIL in the bacterial culture of Pseudomonas aeruginosa (PAK, ST 1763) and the ability of antibodies to recognize this bacterial lectin were verified by Western blotting followed by immunodetection. Appropriate culture conditions have also been found for the expression of this lectin. The...
