Anti-tumor effect was observed in each setting and GVHD was aggravated graft-vs-host disease (GVHD) in the animals when we performed tumor-specific DLI 2 weeks after HCT. GVHD aggravation was observed only in the recipients of MHC-matched HCT, not in those of MHC-mismatched HCT when we performed tumor-specific DLI 8 weeks after HCT. Our pre-clinical data suggest that GVHD aggravation caused by tumor-specific DLI is dependent on timing and MHC disparity. This study will contribute to clinical development of tumor-specific DLI for the tumor-relapsed patients after allogeneic HCT., 2017年度~2019年度科学研究費補助金(基盤研究(C))研究成果報告書, 17K09949}, title = {遺伝子改変同種リンパ球による移植後再発腫瘍治療モデル開発と安全性基盤の確立}, year = {2020}, yomi = {タワラ, イサオ and イケダ, ヒロアキ} }
