Since the cloning of the defective gene in cystic fibrosis, much has been l
earned on the function of CFTR and on the mechanisms regulating its express
ion. Based on the current understanding of the processes involved in lung d
isease progression, a number of approaches have been developed using gene t
herapy and pharmacological agents. Several of these these agents have been
reported to restitute a function to CFTR with specific mutations. Other mol
ecules act on channels other than CFTR, and may be effective by bypassing C
FTR itself. In the present review the various therapeutical strategies curr
ently investigated are discussed. (C) 1998 Elsevier, Paris.
