| Research Abstract |
In this study, Epstein-Barr virus (EBV) was implicated in the pathogenesis of primary central nervous system lymphomas (PCNLs) in immunocompetent hosts (elderly immunocompetent patients ; age≧60 years). Histologically, all cases were diagnosed as diffuse large B-cell lymphoma with extensive necrosis. EBV subtyping-PCR analysis demonstrated that many cases were EBNA 2A type and showed 30-bp LMP-1 deletion on PCR analysis. These results indicate that LMP-1 deletion may have more potent tumor-promoting activity than EBV containing the full-size LMP-1 gene in the pathogenesis of PCNLs in immunocompetent hosts. In addition, some EBV subtypes may show more potent tumor-promoting activity. Regarding chemokines, we have shown that CXCL12/CXCR4 was frequently expressed in PCNLs and other brain cells. Thus, the results suggest that the CXCL12/CXCR4 signaling mediates PCNLs development.
