Outline of Final Research Achievements

CSM14.1 is a rat mesencephalic neuronal cell line that can be induced to differentiate into neurons by culture under non-permissive conditions. CSM14.1 cells become more resistant to Japanese encephalitis virus (JEV) infection as they mature. Differentiation-dependent gene expression in CSM14.1 cells was analyzed by microarray. To identify host molecules that is responsible for the differentiation-dependent susceptibility of neuronal cells with JEV infection, we cloned two genes whose expression in undifferentiated CSM14.1 cell was higher than that in differentiated CSM14.1 cells, and also cloned other two genes whose expression in differentiated CSM14.1 cell was higher than that in undifferentiated CSM14.1 cells. Effect of expression of those genes in undifferentiated CSM14.1 cells on JEV-susceptibility was analyzed.
