Modeling rotavirus infection and antiviral therapy using primary intestinal organoids
Source Yin et al., 2015 · Erasmus MC-University Medical Center, Rotterdam, The Netherlands · 10.1016/j.antiviral.2015.09.010
Abstract
This protocol describes the establishment of three-dimensional primary intestinal organoid cultures from human and mouse tissues and their use as a model system for rotavirus infection and antiviral therapy testing. Human organoids demonstrate high permissiveness to rotavirus, supporting both laboratory-adapted (SA11) and patient-derived strains, with robust production of infectious viral particles. The system enables rapid assessment of individual responsiveness to antiviral agents including interferon-alpha and ribavirin.
