| Research Abstract |
Nasal NK/T-cell lymphoma is EBV-related malignancy, and has a poor prognosis. We have already shown that an expression of LMP-1, EBV-originated oncoprotein, was enhanced by cytokines such as IL-2, 10, and 15 in nasal NK/T-cell lymphoma cell lines. In this study, we found that chemokine IP-10 (Interferon gamma-induced protein-10) was induced by LMP-1, and IP-10 enhanced invasive potential of the cells in autocrine manner. Moreover, we revealed that monocytes attracted by IP-10 enhanced proliferation and LMP-1 expression of the cells by cell-contact manner via membrane-bound IL-15. Therefore, LMP-1 enhanced the proliferating and invasive potential of the cells through IP-10 or monocytes.
