Long-term expanding human airway organoids for disease modeling
Sachs from UMC Utrecht developed human airway organoids (miniature lungs) that offer the possibility to study RSV in an human in vitro model. The authors show that RSV replicates well in human airway organoids and that infection can be inhibited after pre-treatment with palivizumab. Furthermore, RSV caused epithelial changes that mimic disease characteristics such as epithelial shedding, syncytia formation and alterations of the cytoskeleton. Also, there was an upregulation of antiviral genes and an enhanced secretion of cytokines such as IP-10. Both of these findings reflect the immune responses following RSV infection in infants. Lastly, human airway organoids offer the possibility to study the interaction between immune cells and the RSV infected epithelium. The latter is of major importance to increase the knowledge on RSV immune signalling.
Altogether, RSV – infected airway organoids offer the possibility to study numerous aspects of RSV disease, including airway remodelling, immune cell interaction and treatment possibilities.
