Outline of Final Research Achievements |
It has been reported that therapeutic effects of anti-tumor antibodies are dependent on Fc receptor polymorphism that affects affinity between immune cells and antibodies. In this study, we explored novel approaches to genetically modify Fc receptor of NK cells, so as to increase affinity to antibodies and to improve anti-tumor potential of NK cells. Our studies demonstrated that genetic modification of NK cells to express high-affinity Fc receptor enhances their anti-tumor responses in the presence of antibodies. These findings suggest that therapeutic effects of anti-tumor effects in patients who express low-affinity Fc receptor could be improved by a transfer of gene-modified NK cells expressing high-affinity Fc receptor.
