Suppression of the Proliferation of Mouse Splenocytes by Pseudorabies Virus

[摘要] References(18)Pseudorabies virus(PRV)infection in resistant swine caused immunosuppression which sometimes resulted in secondary infection by other viruses or bacteria.However the mechanism of the immunosuppression is not well understood.In this study, the effect of PRV on the immune system was examined in the mouse model.Splenocytes or lymphocytes prepard from the spleen of BALB/c mice were incubated in vitro with mitogen, and the ability of cells to proliferation was measured.When the cells were incubated with PRV, the ability of cells to proliferate was inhibited, although PRV did not multiply in the lymphocytes.UV−inactivated PRV also suppressed the proliferation of mice splenocyte.This result suggests that the structural component of PRV virion might cause the immunosuppression.
