| 1 | Defined tumor antigen-specific T cells potentiate personalized TCR-T cell therapy and prediction of immunotherapy response显示文摘Personalized immunotherapy targeting tumor-specific antigens(TSAs)could generate efficient and safe antitumor immune response without damaging normal tissues.Although neoantigen vaccines have shown therapeutic effect in clinic trials,precise prediction of neoantigens from tumor mutations is still challenging.The host antitumor immune response selects and activates T cells recognizing tumor antigens.Hence,T cells engineered with T-cell receptors(TCRs)from these naturally occurring tumor antigen-specific T(Tas)cells in a patient will target personal TSAs in his/her tumor.To establish such a personalized TCR-T cell therapy,we comprehensively characterized T cells in tumor and its adjacent tissues by single-cell mRNA sequencing(scRNA-seq),TCR sequencing(TCR-seq)and in vitro neoantigen stimulation.Compared to bystander T cells circulating among tissues,Tas cells were characterized by tumor enrichment,tumor-specific clonal expansion and neoantigen specificity.We found that CXCL13 is a unique marker for both CD4^(+)and CD8^(+)Tas cells.Importantly,TCR-T cells expressing TCRs from Tas cells showed significant therapeutic effects on autologous patient-derived xenograft(PDX)tumors.Intratumoral Tas cell levels measured by CXCL13 expression precisely predicted the response to immune checkpoint blockade,indicating a critical role of Tas cells in the antitumor immunity.We further identified CD200 and ENTPD1 as surface markers for CD4^(^(+))and CD8^(^(+))Tas cells respectively,which enabled the isolation of Tas cells from tumor by Fluorescence Activating Cell Sorter(FACS)sorting.Overall,our results suggest that TCR-T cells engineered with Tas TCRs are a promising agent for personalized immunotherapy,and intratumoral Tas cell levels determine the response to immunotherapy. | Jingjing He Xinxin Xiong Han Yang Dandan Li Xuefei Liu Shuo Li Shuangye Liao Siyu Chen Xizhi Wen Kuai Yu Lingyi Fu Xingjun Dong Kaiyu Zhu Xiaojun Xia Tiebang Kang Chaochao Bian Xiang Li Haiping Liu Peirong Ding Xiaoshi Zhang Zhenjiang Liu Wende Li Zhixiang Zuo Penghui Zhou | 2022 | Cell Research2022，32，6： | 10 |

| 3 | Whole‑genome transcriptome and DNA methylation dynamics of pre‑implantation embryos reveal progression of embryonic genome activation in buffaloes显示文摘Background During mammalian pre-implantation embryonic development(PED),the process of maternal-to-zygote transition(MZT)is well orchestrated by epigenetic modification and gene sequential expression,and it is related to the embryonic genome activation(EGA).During MZT,the embryos are sensitive to the environment and easy to arrest at this stage in vitro.However,the timing and regulation mechanism of EGA in buffaloes remain obscure.Results Buffalo pre-implantation embryos were subjected to trace cell based RNA-seq and whole-genome bisulfite sequencing(WGBS)to draw landscapes of transcription and DNA-methylation.Four typical developmental steps were classified during buffalo PED.Buffalo major EGA was identified at the 16-cell stage by the comprehensive analy-sis of gene expression and DNA methylation dynamics.By weighted gene co-expression network analysis,stage-spe-cific modules were identified during buffalo maternal-to-zygotic transition,and key signaling pathways and biological process events were further revealed.Programmed and continuous activation of these pathways was necessary for success of buffalo EGA.In addition,the hub gene,CDK1,was identified to play a critical role in buffalo EGA.Conclusions Our study provides a landscape of transcription and DNA methylation in buffalo PED and reveals deeply the molecular mechanism of the buffalo EGA and genetic programming during buffalo MZT.It will lay a foundation for improving the in vitro development of buffalo embryos. | Penghui Fu Du Zhang Chunyan Yang Xiang Yuan Xier Luo Haiying Zheng Yanfei Deng Qingyou Liu Kuiqing Cui Fei Gao Deshun Shi | 2023 | Journal of Animal Science and Biotechnology2023，14，6： | 0 |
