Purpose : To evaluate apoptosis of cord blood mononuclear cells(CBMC) infected with enterovirus. Methods : Cord blood was obtained from 20 neonates which were delivered vaginally without any complications. Cord blood mononuclear cells(CBMC) were isolated, and after 24h and 48h incubation, cells were stained with Annexin V and Propidium Iodide and were analyzed with FACScan flowcytometer. CBMCs were also incubated with enterovirus and ■-INF. mRNA expression of FasL was evaluated with RT-PCR. Results : The mean rate of apoptosis of CBMC 24 hr after culture with virus showed no definite increase compared to that of culture only group. The mean rate of apoptosis in the culture group with ■-INF was higher than that of culture with virus group(P<0.01) but was not different from the group cultured with virus and ■-INF simultaneously. These findings were also seen in 48- hours-cultured groups. mRNA of CBMC of the groups cultured with ■-INF expressed FasL. Conclusion : The upregulated apoptosis of peripheral lymphocytes in patients with aseptic meningitis may be not due to enterovirus infection directly, but due to some mediators such as ■-INF from immune cells released through enteroviral infection.
