L'epitelio nasale è il sito di barriera primario incontrato da tutti i patogeni respiratori. Qui, descriviamo i metodi per utilizzare le cellule epiteliali nasali primarie cresciute come colture di interfaccia aria-liquido (ALI) per caratterizzare le interazioni coronavirus-ospite umano in un sistema fisiologicamente rilevante.
