| Outline of Final Research Achievements |
The aim of this study is to establish a method for immunostimulation to compensate gene polymorphism-associated deterioration of NK cell function. In mouse models, we found that heat shock protein (HSP)70 inducer enhance the expression of TRAIL on live NK cells. We investigated the effects of epigenetic drugs on immunogenicity of neoplastic cells and function of NK cells by use of clinical specimens and human lymphocytes. In addition, we found that ex vivo licensing NK cells developed from hematopoietic stem cells for adoptive immunotherapy was feasible by cultivating them with HLA class I-KIR matched fibroblasts.
