The correction of protein folding is fundamental for cellular functionality and its failure can lead to severe diseases. In this context, molecular chaperones are crucial players involved in the tricky process of assisting in protein folding, stabilization, and degradation. Chaperones, such as heat shock proteins (HSP) 90, 70, and 60, operate within complex systems, interacting with co-chaperones both to prevent protein misfolding and direct to the correct folding. Chaperone targeting drugs could represent a challenging approach for the treatment of cystic fibrosis (CF), an autosomal recessive genetic disease caused by mutations in the CFTR gene, encoding for the CFTR chloride channel. In this review, we discuss the potential role of molecular chaperones as proteostasis modulators affecting CFTR biogenesis. In particular, we focused on HSP90 and HSP70, for their key role in CFTR folding and trafficking, as well as on HSP60 for its involvement in the inflammation process.

Abstract

The correction of protein folding is fundamental for cellular functionality and its failure can lead to severe diseases. In this context, molecular chaperones are crucial players involved in the tricky process of assisting in protein folding, stabilization, and degradation. Chaperones, such as heat shock proteins (HSP) 90, 70, and 60, operate within complex systems, interacting with co-chaperones both to prevent protein misfolding and direct to the correct folding. Chaperone targeting drugs could represent a challenging approach for the treatment of cystic fibrosis (CF), an autosomal recessive genetic disease caused by mutations in the CFTR gene, encoding for the CFTR chloride channel. In this review, we discuss the potential role of molecular chaperones as proteostasis modulators affecting CFTR biogenesis. In particular, we focused on HSP90 and HSP70, for their key role in CFTR folding and trafficking, as well as on HSP60 for its involvement in the inflammation process.
