囊腫性纖維化
Cystic fibrosis (CF, mucoviscidosis) is a genetic disease with increased viscosity of various secretions leading to organ failure of lung, pancreas and other organs. It is caused in nearly all cases by a deletion of phenylalanine 508 of CFTR (cystic fibrosis transmembrane conductance regulator). This mutation causes a maturation defect of this ion channel protein with increased degradation, mediated by HSPs. Deletion of the co-chaperone AHA1 (activator of heat shock 90kDa protein ATPase homolog 1) leads to stabilization of CFTR and opens up a perspective for a new therapy.
