Journal ArticleDOI
Defective CFTR induces aggresome formation and lung inflammation in cystic fibrosis through ROS-mediated autophagy inhibition
Alessandro Luciani,Valeria Rachela Villella,Speranza Esposito,Nicola Brunetti-Pierri,Diego L. Medina,Carmine Settembre,Manuela Gavina,Laura Pulze,Ida Giardino,Massimo Pettoello-Mantovani,Maria D'Apolito,Stefano Guido,Eliezer Masliah,Brian Spencer,Sonia Quaratino,Valeria Raia,Andrea Ballabio,Luigi Maiuri,Luigi Maiuri +18 more
TL;DR: It is shown how the defective CFTR results in defective autophagy and decreases the clearance of aggresomes, leading to the accumulation of protein aggregates and to lung inflammation.
Journal ArticleDOI
Targeting the Intracellular Environment in Cystic Fibrosis: Restoring Autophagy as a Novel Strategy to Circumvent the CFTR Defect.
Valeria Rachela Villella,Speranza Esposito,Emanuela M. Bruscia,Maria Chiara Maiuri,Valeria Raia,Guido Kroemer,Luigi Maiuri +6 more
TL;DR: Recent pre-clinical evidence indicating that targeting the intracellular environment surrounding the misfolded mutant CFTR instead of protein itself could constitute an attractive therapeutic option to sensitize patients carrying the F508del-CFTR mutation to the beneficial action of CFTR potentiators on lung inflammation is reviewed.
Journal ArticleDOI
Restoration of CFTR function in patients with cystic fibrosis carrying the F508del-CFTR mutation
Daniela De Stefano,Valeria Rachela Villella,Speranza Esposito,Antonella Tosco,Angela Sepe,Fabiola De Gregorio,Laura Salvadori,R. Grassia,Carlo A Leone,Giuseppe De Rosa,Maria Chiara Maiuri,Massimo Pettoello-Mantovani,Stefano Guido,Anna Bossi,A. Zolin,Andrea Venerando,Lorenzo A. Pinna,Anil Mehta,Gianni Bona,Guido Kroemer,Luigi Maiuri,Valeria Raia +21 more
TL;DR: It is reported that oral treatment with cysteamine greatly reduces the mortality rate and improves the phenotype of newborn mice bearing the F508del-CFTR mutation, and optimal schedules of cysteamines plus EGCG might be used for the treatment of CF caused by the F504del- CFTR mutation.
Journal ArticleDOI
Targeting autophagy as a novel strategy for facilitating the therapeutic action of potentiators on ΔF508 cystic fibrosis transmembrane conductance regulator.
Alessandro Luciani,Valeria Rachela Villella,Speranza Esposito,Manuela Gavina,Ilaria Russo,Marco Silano,Stefano Guido,Massimo Pettoello-Mantovani,Rosa Carnuccio,Bob J. Scholte,Antonella De Matteis,Maria Chiara Maiuri,Valeria Raia,Alberto Luini,Guido Kroemer,Luigi Maiuri +15 more
TL;DR: It is demonstrated that human and mouse CF airways are autophagy deficient due to functional sequestration of BECN1 and that the tissue transglutaminase-2 inhibitor, cystamine, or antioxidants restore BECn1-dependent autophamy and reduce SQSTM1/p62 levels, thus favoring ΔF508-CFTR trafficking to the epithelial surface.
Journal ArticleDOI
A novel treatment of cystic fibrosis acting on-target: cysteamine plus epigallocatechin gallate for the autophagy-dependent rescue of class II-mutated CFTR.
Antonella Tosco,F. De Gregorio,Speranza Esposito,D. De Stefano,I Sana,Eleonora Ferrari,Angela Sepe,Laura Salvadori,P. Buonpensiero,A. Di Pasqua,R. Grassia,C A Leone,Stefano Guido,G. De Rosa,Sara Lusa,Gianni Bona,Gautier Stoll,Maria Chiara Maiuri,Anil Mehta,Guido Kroemer,Luigi Maiuri,Valeria Raia +21 more
TL;DR: The proof-of-concept that this combination treatment restored CFTR function and reduced lung inflammation is provided and the results suggest that the combination treatment of cysteamine plus EGCG acts ‘on-target’ because it can only rescueCFTR function when autophagy is functional and improves CFTRfunction when a rescuable protein is expressed.
