An “ex vivo model” contributing to the diagnosis and evaluation of new drugs in cystic fibrosis

Abstract: La fibrosi cistica (FC) è una malattia autosomica recessiva causata da mutazioni nel gene CFTR (Cystic Fibrosis Transmembrane conductance Regulator). Finora sono state descritte circa 2000 mutazioni, ma per la maggior parte di esse è difficile definirne l’effetto senza complesse procedure in vitro. Abbiamo effettuato il campionamento (mediante brushing), la cultura e l’analisi di cellule epiteliali nasali umane (HNEC) utilizzando una serie di tecniche che possono aiutare a testare l’effetto delle mutazioni CFT… Show more

“…Here we show the use of epithelial nasal cells from patients as ex vivo model to evaluate the Kaftrio TM responsiveness on three CF patients with F508del/unknown genotype. Our model of nasal epithelial cells is simple, standardizable and non-invasive for the patient [19,20]. In the present study, all three patients analyzed responded very well to treatment with Kaftrio TM .…”

“…Here we show the use of epithelial nasal cells from patients as ex-vivo model to evaluate the Trikafta responsiveness on three CF patients with F508del/unknown genotype. Our model of nasal epithelial cells is simple, standardizable and non-invasive for the patient [16,17]. In the present study, all three patients analyzed responded very well to treatment with Trikafta.…”

“…On the other hand, given the high number of CFTR variants, functional drug testing on ex vivo models from patients represents a major step to predict effective treatments in an individual setting. International projects to evaluate the efficacy of new molecules on organoids from intestinal or nasal cells from patients with CF with rare mutations are ongoing, but such models are invasive and expensive [28][29][30]. The model of human nasal epithelial cells is a rapid, minimally invasive and effective tool to investigate the effect of novel variants and to assess the effect of novel molecular therapies in individual patients [30][31][32][33][34].…”
