| pubmed-article:15830387 | pubmed:abstractText | Cystic fibrosis (CF) is a progressive disease in which the lung is perceived to be normal at birth and is injured by recurrent infection. However, there is increasing evidence that the lung is functionally and structurally abnormal prior to the appearance of clinical infection. The cystic fibrosis transmembrane regulator (CFTR) is highly expressed in fetal tissues, and this review examines the role of CFTR in regulatory cascades during lung development. Early changes in the CF lung are examined from a perspective of disrupted fetal development, explaining a number of paradoxes seen with the disease. | lld:pubmed |
