Usually You Do Not Need To Be GUCY1B3 Addicted To Get Stung

To test the hypothesis that loss of CFTR alters periciliary liquid depth in the absence of infection, inflammation, and tissue remodeling, A 1331852 we studied pigs 8�C15 hr after birth. In GUCY1B3 depth was not statistically different between non-CF (4.0 �� 0.3 ��m, n?= 5 pigs) and CF (4.7 �� 0.3 ��m, n?= 5 pigs) epithelia (Figure?3G). Compared to earlier studies, our measurements of periciliary liquid depth have the advantages that the epithelia were in?vivo rather than cultured, they were immediately prepared without other manipulations, the epithelia did not demonstrate inflammation from chronic infection, and the experiments were performed at a time point when bacterial eradication was impaired. Our data also agree with an earlier study of maximal cilia length in formalin fixed/paraffin embedded newborn porcine airway epithelia, which showed no difference between CF and non-CF (Meyerholz et?al., 2010a). Potential EAI045 differences with a study of bronchoscopic biopsies in patients with acute and chronic disease (Griesenbach et?al., 2010) raise interesting questions of whether inflammation with its associated effects on surface epithelium and submucosal glands might change ion transport or periciliary liquid height. Although our data show no difference in periciliary liquid depth between CF and non-CF newborn pigs, it is possible that with time and progression of disease, the depth of periciliary liquid might differ between the genotypes.
