ABSTRACT
Cystic fibrosis (CF) is a common and life-threatening autosomal recessive disorder in Caucasians populations. The disease is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. The absence of mature CFTR at the correct cellular location or dysfunction of CFTR proteins has been observed in CF patients. CF is frequently accompanied by a variety of complex complications, such as impairments in pulmonary functions, which may lead to successive infections and respiratory failure. Recently, with the understanding of the pathogenesis of CF, a wide array of therapeutic strategies for the treatment of CF has been designed. This review summarizes pathogenic mechanisms of CF, mechanisms of action of drugs, routes of administration, and new drug development as well as provides insights into the advanced treatment strategies for CF.
