| Research Abstract |
In the present study, it was elucidated that parvoviral nonstructure (NS) protein induced DNA methylation in T lymphocytes and caused change of apoptosis resistancy and cell proliferation. Moreover, a possible effect of NS for incidence of collagen-induced arthritis was examined in vivo. The most of mouse T lymphocytes infected with NS-EGFP expression vector caused apoptosis, and the survived cells suppressed Bmper expression by DNA methylation. These cells acquired to be resistant for parvoviral re-infection. DBA/1 mice infected with NS-EGFP expression vector developed collagen-induced arthritis, though there was no significant difference on incidence of them to that of the control.
