La mucoviscidose est une maladie génétique mortelle qui touche principalement les personnes d’origine caucasienne. Elle est causée par des mutations du gène CFTR, qui code pour un canal ionique chlorure. La mutation la plus fréquente, ∆F508, modifie le repliement de la protéine CFTR et empêche son expression à la surface des cellules épithéliales, perturbant ainsi le transport des ions et de l’eau et entraînant la production d’un mucus épais, caractéristique de l’atteinte pulmonaire liée à la mucoviscidose. Les traitements ont progressé : les antibiotiques permettent de gérer les infections chroniques et les modulateurs du gène CFTR (ivacaftor, tezacaftor, elexacaftor) améliorent la fonction de la protéine. Cependant, de nombreux patients porteurs de mutations rares ou présentant une résistance aux médicaments restent sans traitement. Les thérapies émergentes se concentrent désormais sur la thérapie génique, visant à corriger ou remplacer le gène CFTR défectueux, et sur la thérapie cellulaire, pour régénérer un épithélium fonctionnel à partir de cellules souches corrigées. L’association de ces stratégies offre une voie prometteuse vers une correction personnalisée et durable de la cause moléculaire de la mucoviscidose.

  • Viral Replication Complexes
    Viruses are obligate intracellular parasites that need to co-opt a living cell’s machinery for replication. At the heart of the viral replication machinery are the nucleic acid polymerases, which are responsible for efficiently copying the viral genome. This process must often be coordinated with other viral processes, including protein translation and viral packaging. The poly...

    The flaviviruses are composed almost entirely of arthropod-borne viruses, a subset of which are responsible for millions of cases of human disease each year. Among these viruses are dengue virus—a scourge throughout the tropical regions of Asia and the Americas; yellow fever virus—the “original” hemorrhagic fever virus; and the recently emerged Zika virus. While the flaviviruse...

    This edited book brings together research reports on the asymmetry of brain function in various species, including humans, dogs, birds, lizards and bees. As shown in a wide range of species, and, as we now know, not solely in humans, the left and right sides of the brain process information in different ways and control different responses or patterns of behaviour. Since this d...

    Joëlle Roche
    The epithelial-to-mesenchymal transition (EMT) is a highly dynamic process with multiple transitional states, by which epithelial cells can convert into a mesenchymal phenotype. This process involves loss of cellular adhesion and cellular polarity, and an improvement in migratory and invasive properties. It occurs during normal embryonic development, tissue regeneration, organ ...

There has been progress in the treatment of acute m...
