Abstract: The invention concerns a novel approach for treating cystic fibrosis using, in particular, anti-cancer chemotherapy. For the treatment of cystic fibrosis it proposes the use of at least one product which when administered to a patient brings about the expression or overexpression of an ABC carrier compound, in particular glutathione carrier. Preferably, the products used are anti-cancer products whose administration brings about the expression of MRP and/or MDR protein. The invention is also applicable to the treatment of rheumatoid polyarthritis or asthma.
