| 1 | The kinase AKT1 potentiates the suppressive functions of myeloid-derived suppressor cells in inflammation and cancer显示文摘Myeloid-derived suppressor cells(MDSCs)are a group of heterogeneous cells1 that play crucial negative regulatory roles in immune-associated diseases,including infections,2 cancer,3 transplantation4,and autoimmunity.5 We and others have shown that mTOR signaling and its downstream metabolic pathways regulate MDSC recruitment and function in inflammation and autoimmunity. | Anna Jia Yuexin Wang Yufei Wang Yan Li Qiuli Yang Yejin Cao Ying He Lin Dong Yingjie Dong Yueru Hou Ruoning Wang Yujing Bi Guangwei Liu | 2021 | Cellular & Molecular Immunology2021，18，4： | 7 |
| 2 | IL-17A-dependent gut microbiota is essential for regulating diet-induced disorders in mice显示文摘The gut microbiota plays a key role in obesity and related metabolic disorders, and multiple factors including diet, host genotype, and age regulate it. Many studies have examined the contribution of extrinsic factors to the regulation of the gut microbiota, but the importance of the host genetic constitution cannot be ignored. Interleukin 17A(IL-17A), a pro-inflammatory cytokine, is important in the defense against infection and diseases. Here, we investigated the association among IL-17, a high-fat diet(HFD), and the gut microbiota. Mice deficient in IL-17A were resistant to diet-induced obesity and related diseases. Compared with the Ⅱ-17^(-/-)mice, wild-type(WT) mice challenged with HFD showed obvious weight fluctuations, such as those seen in type 2 diabetes, and hematological changes similar to those associated with metabolic syndrome. However, housing WT mice and Ⅱ-17a^(-/-)mice together significantly alleviated these symptoms in the WT mice. A metagenomic analysis of the mouse feces indicated that the microbial community compositions of these two groups differed before HFD feeding. The HFD mediated shifts in the gut microbial compositions, which were associated with the mouse phenotypes.We also identified potentially beneficial and harmful species present during this period, and drew networks of the most abundant species. A functional analysis indicated pathway changes in the WT and Ⅱ-17a^(-/-)mice when fed the HFD. Collectively, these data underscore the importance of the host factor IL-17 A in shaping and regulating the gut microbiota, which conversely, influences the host health. | Yujing Bi Chunxiao Li Lin Liu Jiyuan Zhou Zhengchao Li Huimin Deng Chunyan Wu Yanping Han Yajun Song Yafang Tan Xiaoyi Wang Zongmin Du Yujun Cui Yanfeng Yan Fachao Zhi Guangwei Liu Nan Qin Heping Zhang Ruifu Yang | 2017 | Science Bulletin2017，62，15： | 5 |
| 3 | Alterations in gut microbiota and metabolites associated with altitude-induced cardiac hypertrophy in rats during hypobaric hypoxia challenge显示文摘The gut microbiota is involved in host responses to high altitude.However,the dynamics of intestinal microecology and their association with altitude-related illness are poorly understood.Here,we used a rat model of hypobaric hypoxia challenge to mimic plateau exposure and monitored the gut microbiome,short-chain fatty acids(SCFAs),and bile acids(BAs)over 28 d.We identified weight loss,polycythemia,and pathological cardiac hypertrophy in hypoxic rats,accompanied by a large compositional shift in the gut microbiota,which is mainly driven by the bacterial families of Prevotellaceae,Porphyromonadaceae,and Streptococcaceae.The aberrant gut microbiota was characterized by increased abundance of the Parabacteroides,Alistipes,and Lactococcus genera and a larger Bacteroides to Prevotella ratio.Trans-omics analyses showed that the gut microbiome was significantly correlated with the metabolic abnormalities of SCFAs and BAs in feces,suggesting an interaction network remodeling of the microbiome-metabolome after the hypobaric hypoxia challenge.Interestingly,the transplantation of fecal microbiota significantly increased the diversity of the gut microbiota,partially inhibited the increased abundance of the Bacteroides and Alistipes genera,restored the decrease of plasma propionate,and moderately ameliorated cardiac hypertrophy in hypoxic rats.Our results provide an insight into the longitudinal changes in intestinal microecology during the hypobaric hypoxia challenge.Abnormalities in the gut microbiota and microbial metabolites contribute to the development of high-altitude heart disease in rats. | Zhiyuan Pan Yichen Hu Zongyu Huang Ni Han Yan Li Xiaomei Zhuang Jiye Yin Hui Peng Quansheng Gao Wenpeng Zhang Yong Huang Yujun Cui Yujing Bi Zhenjiang Zech Xu Ruifu Yang | 2022 | Science China(Life Sciences)2022，65，10： | 5 |
| 4 | Glucocorticoid receptor promotes the function of myeloid-derived suppressor cells by suppressing HIF1α-dependent glycolysis显示文摘Immunomodulatory signaling imposes tight regulations on metabolic programs within immune cells and consequentially determines immune response outcomes.Although the glucocorticoid receptor(GR)has been recently implicated in regulating the function of myeloid-derived suppressor cells(MDSCs),whether the dysregulation of GR in MDSCs is involved in immune-mediated hepatic diseases and how GR regulates the function of MDSCs in such a context remains unknown.Here,we revealed the dysregulation of GR expression in MDSCs during innate immunological hepatic injury(IMH)and found that GR regulates the function of MDSCs through modulating HIF1α-dependent glycolysis.Pharmacological modulation of GR by its agonist(dexamethasone,Dex)protects IMH mice against inflammatory injury.Mechanistically,GR signaling suppresses HIF1αand HIF1α-dependent glycolysis in MDSCs and thus promotes the immune suppressive activity of MDSCs.Our studies reveal a role of GR-HIF1αin regulating the metabolism and function of MDSCs and further implicate MDSC GR signaling as a potential therapeutic target in hepatic diseases that are driven by innate immune cell-mediated systemic inflammation. | Yun Lu Huanrong Liu Yujing Bi Hui Yang Yan Li Jian Wang Zhengguo Zhang Yu Wang Chunxiao Li Anna Jia Linian Han Ying Hu Yong Zhao Ruoning Wang Guangwei Liu | 2018 | Cellular & Molecular Immunology2018，15，6： | 4 |
| 5 | Transcriptomic Response to Yersinia pestis:RIG-I Like Receptor Signaling Response Is Detrimental to the Host against Plague显示文摘Bacterial pathogens have evolved various mechanisms to modulate host immune responses for successful infection.In this study,RNAsequencing technology was used to analyze the responses of human monocytes THP1 to Yersinia pestis infection.Over 6000 genes were differentially expressed over the 12 h infection.Kinetic responses of pathogen recognition receptor signaling pathways,apoptosis,antigen processing,and presentation pathway and coagulation system were analyzed in detail.Among them,RIG-I-like receptor(RLR) signaling pathway,which was established for antiviral defense,was significantly affected.Mice lacking MAVS,the adaptor of the RLR signahng pathway,were less sensitive to infection and exhibited lower IFN-P production,higher Thl-type cytokines IFN-y and IL-12 production,and lower Th2-type cytokines EL-4 and IL-13 production in the serum compared with wild-type mice.Moreover,infection of pathogenic bacteria other than Y.pestis also altered the expression of the RLR pathway,suggesting that the response of RLR pathway to bacterial infection is a universal mechanism. | Zongmin Du Huiying Yang Yafang Tan Guang Tian Qingwen Zhang Yujun Cui Yanfeng Yan Xiaohong Wu Zuyun Chen Shiyang Cao Yujing Bi Yanping Han Xiaoyi Wang Yajun Song Ruifu Yan | 2014 | Journal of Genetics and Genomics2014，41，7： | 2 |
| 6 | A large-scale outdoor atmospheric simulation smog chamber for studying atmospheric photochemical processes:Characterization and preliminary application显示文摘Understanding the formation mechanisms of secondary air pollution is very important for the formulation of air pollution control countermeasures in China.Thus,a large-scale outdoor atmospheric simulation smog chamber was constructed at Chinese Research Academy of Environmental Sciences(the CRAES Chamber),which was designed for simulating the atmospheric photochemical processes under the conditions close to the real atmospheric environment.The chamber consisted of a 56-m^(3) fluorinated ethylene propylene(FEP) Teflon film reactor,an electrically-driven stainless steel alloy shield,an auxiliary system,and multiple detection instrumentations.By performing a series of characterization experiments,we obtained basic parameters of the CRAES chamber,such as the mixing ability,the background reactivity,and the wall loss rates of gaseous compounds(propene,NO,NO_(2),ozone) and aerosols(ammonium sulfate).Oxidation experiments were also performed to study the formation of ozone and secondary organic aerosol(SOA),including α-pinene ozonolysis,propene and 1,3,5-trimethylbenzene photooxidation.Temperature and seed effects on the vapor wall loss and SOA yields were obtained in this work:higher temperature and the presence of seed could reduce the vapor wall loss;SOA yield was found to depend inversely on temperature,and the presence of seed could increase SOA yield.The seed was suggested to be used in the chamber to reduce the interaction between the gas phase and chamber walls.The results above showed that the CRAES chamber was reliable and could meet the demands for investigating tropospheric chemistry. | Junling Li Hong Li Xuezhong Wang Weigang Wang Maofa Ge Hao Zhang Xin Zhang Kun Li Yan Chen Zhenhai Wu Fahe Chai Fan Meng Yujing Mu Abdelwahid Mellouki Fang Bi Yujie Zhang Lingyan Wu Yongchun Liu | 2021 | Journal of Environmental Sciences2021，33，4： | 2 |

| 8 | Review on cryogenic technologies for CO_(2) removal from natural gas显示文摘CO_(2) in natural gas(NG)is prone to condense directly from gas to solid or solidify from liquid to solid at low temperatures due to its high triple point and boiling temperature,which can cause a block of equipment.Meanwhile,CO_(2) will also affect the calorific value of NG.Based on the above reasons,CO_(2) must be removed during the NG liquefaction process.Compared with conventional methods,cryogenic technologies for CO_(2) removal from NG have attracted wide attention due to their nonpolluting and low-cost advantages.Its integration with NG liquefaction can make rational use of the cold energy and realize the purification of NG and the production of byproduct liquid CO_(2).In this paper,the phase behavior of the CH_(4)-CO_(2) binary mixture is summarized,which provides a basis for the process design of cryogenic CO_(2) removal from NG.Then,the detailed techniques of design and optimization for cryogenic CO_(2) removal in recent years are summarized,including the gas-liquid phase change technique and the gas-solid phase change technique.Finally,several improvements for further development of the cryogenic CO_(2) removal process are proposed.The removal process in combination with the phase change and the traditional techniques with renewable energy will be the broad prospect for future development. | Yujing BI Yonglin JU | 2022 | Frontiers in Energy2022，16，5： | 1 |

| 11 | Crucial role of histone deacetylase SIRT1 in myeloid-derived suppressor cell-mediated reprogramming of CD4^(+) T-cell differentiation显示文摘Myeloid-derived suppressor cells(MDSCs)are heterogeneous,immature myeloid cells that inhibit the immune responses of T cells.1–5 MDSCs play a crucial role in infection,6,7 transplantation,8,9 autoimmune diseases10,11,and tumors12,13 by driving the differentiation of specific T-cell subsets,but the precise regulatory mechanism is still unclear.Recently,our results showed that SIRT1,a histone deacetylase,suppresses the functions of proinflammatory MDSCs and promotes tumor growth.14 However,it remains unclear whether SIRT1 regulates the MDSC-induced differentiation of T cells.Here,we identified the regulatory effects of SIRT1 in CD11b+Gr1+MDSCs on T-cell differentiation. | Lin Dong Yujing Bi Anna Jia Qing Yu Yuexin Wang Yufei Wang Qiuli Yang Yejin Cao Ying He Ruichen Liu Yan Li Guangwei Liu | 2020 | Cellular & Molecular Immunology2020，17，7： | 0 |
| 12 | Genetic and Functional Differences of Escherichia coli Strains from Colorectal Cancer Mucosal Tissues显示文摘Colorectal cancer(CRC)is the third leading cancer globally.Metagenomics has been widely used to analyze the association between the gut microbiota and CRC based on bacterial genus-or species-level comparisons,providing evidence of dysbiosis in CRC development.However,this kind of analysis is unable to provide strain-level information for understanding the individual role of a species in CRC.Here,we used culturomics to isolate CRC mucosal samples and selected 158 Escherichia coli strains to reveal their differences in both genomics and functions by means of phylogenetic analysis and inflammatory induction based on cell and animal experiments.Through genomic comparison,these strains were divided into five phylogroups.The representative strains of each phylogroup significantly induced different levels of cytokine secretion by human leukemic monocyte(THP-1 cell)-based Transwell and animal experiments.Further bioinformatic analysis revealed different profiles of single-nucleotide polymorphisms,genes,and metabolic pathways in the different phylogroups,which can improve the current understanding of the phenotypic differences between these strains.The strain differences revealed in both genomics and functions indicate that the microbiota’s function at the strain level should be investigated in order to understand the interacting mechanisms between hosts and gut bacteria. | Yuxiao Chang Xiang Li Lei Ding Chao Yang Zhiyuan Pan Ni Han Yujun Cui Fachao Zhi Ruifu Yang Hong Gao Yujing Bi | 2022 | Engineering2022，，9： | 0 |

| 14 | Arabidopsis SYP121 acts as an ROP2 effector in the regulation of root hair tip growth显示文摘Tip growth is an extreme form of polarized cell expansion that occurs in all eukaryotic kingdoms to generate highly elongated tubular cells with specialized functions, including fungal hyphae, animal neurons, plant pollen tubes, and root hairs (RHs). RHs are tubular structures that protrude from the root epidermis to facilitate water and nutrient uptake, microbial interactions, and plant anchorage. RH tip growth requires polarized vesicle targeting and active exocytosis at apical growth sites. However, how apical exocytosis is spatially and temporally controlled during tip growth remains elusive. Here, we report that the Qa-Soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) SYP121 acts as an effector of Rho of Plants 2 (ROP2), mediating the regulation of RH tip growth. We show that active ROP2 promotes SYP121 targeting to the apical plasma membrane. Moreover, ROP2 directly interacts with SYP121 and promotes the interaction between SYP121 and the R-SNARE VAMP722 to form a SNARE complex, probably by facilitating the release of the Sec1/Munc18 protein SEC11, which suppresses the function of SYP121. Thus, the ROP2-SYP121 pathway facilitates exocytic trafficking during RH tip growth. Our study uncovers a direct link between an ROP GTPase and vesicular trafficking and a new mechanism for the control of apical exocytosis, whereby ROP GTPase signaling spatially regulates SNARE complex assembly and the polar distribution of a Q-SNARE. | Xiankui Cui Shuwei Wang Yaohui Huang Xuening Ding Zirong Wang Lidan Zheng Yujing Bi Fanghui Ge Lei Zhu Ming Yuan Shaul Yalovsky Ying Fu | 2022 | Molecular Plant2022，15，6： | 0 |
