  • Epstein-Barr virus-negative NK cell line
    Patent number: 7781210
    Abstract: The present invention provides Epstein-Barr virus (EBV)-negative NK cell lines. The NK cell lines of the present invention are useful for screening factors associated with the proliferation and expression functions of NK cells and to discover factors produced by the NK cells. In addition, the cell lines are immortalized despite the fact that they are EBV-negative. Thus, unknown mechanisms of oncogenesis may be elucidated through an understanding of the mechanisms underlying the immortalization of the cell lines of the present invention.
