An improved cell line-derived xenograft humanized mouse model for evaluation of PD-1/PD-L1 blocker BMS202-induced immune responses in colorectal cancer
文献摘要:
The establishment of an in vivo mouse model mimicking human tumor-immune environments provides a pro-mising platform for immunotherapy assessment,drug discovery and clinical decision guidance.To this end,we construct humanized NCG mice by transplanting human hCD34+hematopoietic progenitors into non-obese dia-betic(NOD)Cg-PrkdcscidIL2rgrm1wjl/Sz(null;NCG)mice and monitoring the development of human hematopoietic and immune systems(Hu-NCG).The cell line-derived xenograft(CDX)Hu-NCG mouse models are set up to assess the outcome of immunotherapy mediated by the small molecule BMS202.As a PD-1/PD-L1 blocker,BMS202 shows satisfactory antitumour efficacy in the HCT116 and SW480 xenograft Hu-NCG mouse models.Mechanistically,BMS202 exerts antitumour efficacy by improving the tumor microenvironment and enhancing the infiltration of hCD8+T cells and the release of hIFNγ in tumor tissue.Thus,tumor-bearing Hu-NCG mice are a suitable and important in vivo model for preclinical study,particularly in cancer immunotherapy.
