T cell-receptor transgenic NOD8.3 mice provide a model for spontaneous type 1 diabetes development. Infection of 5 week-old NOD8.3 mice with Rhesus monkey rotavirus (RRV) accelerates the onset of their diabetes. This acceleration requires virus replication and relates to the presence and level of serum anti-rotavirus antibodies, but the role of individual RRV genes is unknown. Here we assessed the importance for diabetes acceleration of the RRV genes encoding VP4 and VP7, by infecting NOD8.3 mice with parental and reassortant rotaviruses. Diabetes was accelerated by reassortant rotaviruses containing RRV VP7 on a UK rotavirus genetic background, but not by parental UK or a UK reassortant con..View full abstract
