| Research Abstract |
In order to a movement of virus in an experimental model of IgA nephropathy, detecting a virus-specific RNA using an in situ hybridization and a virus-surface protein with an immunoflurorescence study of mice intravenously inculated once with coxsackievirus B4 (10^7TCD_<50> : Cox.B4) were carried out.
The signal of the Cox.B4-specific RNA was observed in the mesangial areas from 6 hours to 28 days after the inoculation. Cox.B4-surface protein was not detected at 6 hours after the inoculation, but was observed at 28 days in the mesangial areas.
Inoculated Cox.B4 have revealed the signal of the Cox.B4-specific RNA in the mesangial areas for a long time, and produce the surface protein in the same areas after 28 days. These findings suggest that in situ immune complexes are maked by responding to virus-surface protein and virus antibody in the mesangial areas.
