| 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 |
| 2 | Jiangtang Xiaoke granule attenuates glucose metabolism disorder via regulating endoplasmic reticulum stress in the liver of type 2 diabetes mellitus mice显示文摘OBJECTIVE:To observe the effect of Jiangtang Xiaoke(JTXK) granule on endoplasmic reticulum(ER)stress in high fat diet(HFD)-induced type 2 diabetes mellitus(T2 DM) KK-Ay mice.METHODS:KK-Ay mice were fed with HFD to induce the T2 DM model,while normal control C57 BL/6 J mice were given standard feed.Fasting blood glucose(FBG) in all mice was measured weekly and oral glucose tolerance tests(OGTTs) were performed at 4 and 10 weeks after start of treatment to determine glucose metabolism.Serum fasting insulin(FINS) and insulin sensitivity index(ISI) were measured to determine insulin sensitivity.m RNA expressions of eukaryotic initiation factor-2 alpha(e IF2α),glucose regulated protein 78(GRP78),activating transcription factor 4(ATF4),and C/EBP homology protein(CHOP) were assessed by reverse transcription polymerase chain reaction and the protein expressions of p-e IF2α,GRP78,and CHOP were assessed by Western blotting.RESULTS:JTXK granule significantly reduced FBG and free fatty acid levels and improved OGTT at the120 min of the 10-week treatment in T2 DM KK-Ay mice.FINS and Hb Alc levels were reduced and insulin sensitivities were increased in KK-Ay diabetic mice,which were improved with the treatment of JTXK granule,especially at the 7 and 3.5 g/kg doses.JTXK granule at the 3.5 g/kg dose was most effective in reducing both gene and protein expressions of e IF2α,GRP78,and CHOP.CONCLUSION:ER stress response is increased in T2 DM KK-Ay mice.Treatment with JTXK granule attenuates glucose disorders,improves insulin sensitivity,and reduces serum FFA in T2 DM KK-Ay mice.The mechanisms may be attributed to regulation of the signaling ER stress pathway via decreasing e IF2α phosphorylation and suppressing e IF2α-ATF4-CHOP activation. | Zhang Yi Mo Fangfang Zhang Dongwei Gao Sihua Zhao Dandan Yu Na Mu Qianqian Zuo Jiacheng Ma Yue | 2018 | Journal of Traditional Chinese Medicine2018，38，4： | 3 |

| 7 | Rapid bioluminescence assay for monitoring rat CES1 activity and its alteration by traditional Chinese medicines显示文摘In traditional Chinese medicine herbs(TCM),including Radix Salviae Miltiorrhizae(Danshen),Radix Puerariae Lobatae(Gegen),Radix Angelicae Sinensis(Danggui),and Rhizoma Chuanxiong(Chuanxiong)are widely used for the prevention and treatment of cardiovascular diseases and also often co-administered with Western drugs as a part of integrative medicine practice.Carboxylesterase 1(CES1)plays a pivotal role in the metabolisms of pro-drugs,Since(S)-2-(2-(6-dimethylamino)-benzothiazole)-4,5-dihydrothiazole-4-carboxylate(NLMe)has recently been identified by us as a selective CES1 bioluminescent sensor,we developed a rapid method using this substrate for the direct measurement of CES1 activity in rats.This bioluminescence assay was applied to determine CES1 activity in rat tissues after a two-week oral administration of each of the four herbs noted above.The results demonstrated the presence of CES1 enzyme in rat blood and all tested tissues with much higher enzyme activity in the blood,liver,kidney and heart than that in the small intestine,spleen,lung,pancreas,brain and stomach.In addition,the four herbs showed tissue-specific effects on rat CES1 expression.Based on the CES1 biodistribution and its changes after treatment in rats,the possibility that Danshen,Gegen and Danggui might alter CES1 activities in human blood and kidney should be considered.In summary,a selective and sensitive bioluminescence assay was developed to rapidly evaluate CES1 activity and the effects of orally administered TCMs in rats. | Jun Zhang Dandan Wang Liwei Zou Min Xiao Yufeng Zhang Ziwei Li Ling Yang Guangbo Ge Zhong Zuo | 2020 | Journal of Pharmaceutical Analysis2020，10，3： | 1 |

| 9 | Single-cell analysis defines the lineage plasticity of stem cells in cervix epithelium显示文摘Information about the dynamic change and post-injury regeneration of cervical epithelium is relatively rare,even though it is tightly related to gynecologic malignancy.Here,using a feeder cell-based culturing system,we stably cloned mouse and human P63 and KRT5 expressing cells from the adult cervix as putative cervical stem/progenitor cells(CVSCs).When subjected to differentiation,the cultured cells gave rise to mature cervical epithelium by differentiating into squamous or glandular cells.The ability of endogenous mouse CVSCs to reconstitute cervical epithelium after injury was also evident from the genetic lineage tracing experiments.Single-cell transcriptomic analysis further classified the CVSCs into three subtypes and delineated their bi-lineage differentiation roadmap by pseudo-time analysis.We also tracked the real-time differentiation routes of two representing single CVSC lines in vitro and found that they recapitulated the predicted roadmap in pseudo-time analysis.Signaling pathways including Wnt,TGF-beta,Notch and EGFR were found to regulate the cervical epithelial hierarchy and implicated the different roles of distinct types of cells in tissue homeostasis and tumorigenesis.Collectively,the above data provide a cloning system to achieve stable in vitro culture of a bi-lineage stem/progenitor cell population in the cervix,which has profound implications for our understanding of the cervix stem/progenitor cell function in homeostasis,regeneration,and disease and could be helpful for developing stem cell-based therapies in future. | Zixian Zhao Yujia Wang Yingchuan Wu Dandan Li Ting Zhang Yu Ma Xiaoming Teng Wei Zuo | 2021 | Cell Regeneration2021，10，1： | 0 |
| 10 | Ginsenoside rg3 reduces body weight by regulating fat content and browning in obese mice显示文摘Objective:To determine the effects of ginsenoside rg3 on the body weight of C57BL/6J obese mice and to investigate its underlying weight loss mechanisms with a focus on white fat browning-related factors.Methods:Eight-week-old C57BL/6J male mice were fed a high-fat diet for 12 successive weeks to construct the obese model.C57BL/6J male mice were fed a standard chow diet to construct normal control group.After 8 weeks of intervention with ginsenoside rg3,the food intake,body weight,body fat mass,blood sugar,and lipid profiles of the mice in each group were detected.Hematoxylin and eosin(HE)staining was used to observe the histological morphology of the adipose tissues.Real-time polymerase chain reaction(RT-PCR)and Western blotting(WB)were applied to detect the gene and protein expression levels of peroxisome proliferators-activated receptor gama(PPARg),Peroxisome proliferatoractivated receptor-gamma coactivator-1alpha(PGC-1a),PR domain containing 16(PRDM16),and uncoupling protein 1(UCP-1).Results:Compared to normal control group mice,the body weight,food intake,body fat composition,and blood lipid levels of model group mice increased significantly.After 8 weeks of intervention with ginsenoside rg3,body weight,body fat composition,food intake,and blood lipid profiles decreased.HE staining showed that ginsenoside rg3 can improve white adipocyte hypertrophy to a certain extent.RTPCR and WB demonstrated that ginsenoside rg3 can increase the mRNA and protein expression levels of PPARg,PGC-1a,PRDM16,and UCP-1 in the adipose tissues of obese mice.Conclusion:The weight reduction effect of ginsenoside rg3 may be related to the promotion of white fat browning. | Qianqian Mu Jiacheng Zuo Dandan Zhao Xiaoshan Zhou Jing Hua Ying Bai Fangfang Mo Xin Fang Min Fu Sihua Gao | 2021 | Journal of Traditional Chinese Medical Sciences2021，8，1： | 0 |
| 11 | One‑Step Gas-Solid‑Phase Diffusion‑Induced Elemental Reaction for Bandgap‑Tunable Cu_(a)Agm_(1)Bim_(2)I_(n)/CuI Thin Film Solar Cells显示文摘Lead-free inorganic copper-silver-bismuth-halide materials have attracted more and more attention due to their environmental friendliness,high element abundance,and low cost.Here,we developed a strategy of one-step gas-solid-phase diffusioninduced reaction to fabricate a series of bandgap-tunable Cu_(a)Agm_(1)Bim_(2)I_(n)/CuI bilayer films due to the atomic diffusion effect for the first time.By designing and regulating the sputtered Cu/Ag/Bi metal film thickness,the bandgap of Cu_(a)Agm_(1)Bim_(2)I_(n)/CuI could be reduced from 2.06 to 1.78 eV.Solar cells with the structure of FTO/TiO_(2)/Cu_(a)Agm_(1)Bim_(2)I_(n)/CuI/carbon were constructed,yielding a champion power conversion efficiency of 2.76%,which is the highest reported for this class of materials owing to the bandgap reduction and the peculiar bilayer structure.The current work provides a practical path for developing the next generation of efficient,stable,and environmentally friendly photovoltaic materials. | Erchuang Fan Manying Liu Kangni Yang Siyu Jiang Bingxin Li Dandan Zhao Yanru Guo Yange Zhang Peng Zhang Chuantian Zuo Liming Ding Zhi Zheng | 2023 | Nano-Micro Letters2023，15，4： | 0 |
