| 1 | Inhibiting Hv1 channel in peripheral sensory neurons attenuates chronic inflammatory pain and opioid side effects显示文摘Both opioids and nonsteroidal anti-inflammatory drugs(NSAIDS)produce deleterious side effects and fail to provide sustained relief in patients with chronic inflammatory pain.Peripheral neuroinflammation(PN)is critical for initiation and development of inflammatory pain.A better understanding of molecular mechanisms underlying PN would facilitate the discovery of new analgesic targets and the development of new therapeutics.Emerging evidence suggests that peripheral sensory neurons are not only responders to painful stimuli,but are also actively engaged in inflammation and immunity,whereas the intrinsic regulatory mechanism is poorly understood.Here we report the expression of proton-selective ion channel Hv1 in peripheral sensory neurons in rodents and humans,which was previously shown as selectively expressed in microglia in mammalian central nervous system.Neuronal Hv1 was up-regulated by PN or depolarizing stimulation,which in turn aggravates inflammation and nociception.Inhibiting neuronal Hv1 genetically or by a newly discovered selective inhibitor YHV98-4 reduced intracellular alkalization and ROS production in inflammatory pain,mitigated the imbalance in downstream SHP-1-pAKT signaling,and also diminished pro-inflammatory chemokine release to alleviate nociception and morphine-induced hyperalgesia and tolerance.Thus,our data reveal neuronal Hv1 as a novel target in analgesia strategy and managing opioids-related side effects. | Qiansen Zhang Yimin Ren Yiqing Mo Peipei Guo Ping Liao Yuncheng Luo Jie Mu Zhuo Chen Yang Zhang Ya Li Linghui Yang Daqing Liao Jie Fu Juwen Shen Wei Huang Xuewen Xu Yanyan Guo Lianghe Mei Yunxia Zuo Jin Liu Huaiyu Yang Ruotian Jiang | 2022 | Cell Research2022，32，5： | 3 |

| 8 | Apoptotic gene expression in the neural tube during early human embryonic development显示文摘Neural tube development comprises neural induction,neural epithelial cell proliferation,and apoptosis,as well as migration of nerve cells.Too much or too little apoptosis leads to abnormal nervous system development.The present study analyzed expression and distribution of apoptotic-related factors,including Fas,FasL,and caspase-3,during human embryonic neural tube development.Experimental results showed that increased caspase-3 expression promoted neural apoptosis via a mitochondrial-mediated intrinsic pathway at 4 weeks during early human embryonic neural tube development.Subsequently,Fas and FasL expression increased during embryonic development.The results suggest that neural cells influence neural apoptosis through synergistic effects of extrinsic pathways.Therefore,neural apoptosis during the early period of neural tube development in the human embryo might be regulated by the death receptor induced apoptotic extrinsic pathways. | Guifang Chen Tiandong Li Peipei Ding Ping Yang Xiao Zhang | 2011 | Neural Regeneration Research2011，6，1： | 0 |
| 9 | Influence of Recirculated Flue Gas Distribution on Combustion and NOx Formation Characteristics in S-CO_(2) Coal-fired Boiler显示文摘Supercritical carbon dioxide(S-CO_(2))Brayton power cycle power generation technology,has attracted more and more scholars'attention in recent years because of its advantages of high efficiency and flexibility.Compared with conventional steam boilers,S-CO_(2) has different heat transfer characteristics,it is easy to cause the temperature of the cooling wall of the boiler to rise,which leads to higher combustion gas temperature in the furnace,higher NOX generation concentration.The adoption of flue gas recirculation has a significance impact on the combustion process of pulverized coal in the boiler,and it is the most effective ways to reduce the emission of NOX and the combustion temperature in the boiler.This paper takes 1000MW S-CO_(2) T-type coal-fired boiler as the research target to investigate the combustion and NOX generation characteristics of S-CO_(2) coal-fired boilers under flue gas recirculation condition,the influence of recirculated flue gas distribution along the furnace height on the characteristics of NOX formation and the combustion of pulverized coal.The results show that the recirculated flue gas distribution has the great impact on the concentration of NOX at the boiler outlet.When the bottom recirculation flue gas rate is gradually increased,the average temperature of the lower boiler decreases and the average temperature of the upper boiler increases slightly;The concentration of NOx at the furnace outlet increases. | Peipei WANG Mingyan GU Yao FANG Boyu JIANG Mingming WANG Ping CHEN | 2021 | Mechanical Engineering Science2021，3，2： | 0 |
| 10 | Increasing Fusarium verticillioides resistance in maize by genomicsassisted breeding:Methods,progress,and prospects显示文摘Maize(Zea mays L.)is an indispensable crop worldwide for food,feed,and bioenergy production.Fusarium verticillioides(F.verticillioides)is a widely distributed phytopathogen and incites multiple destructive diseases in maize:seedling blight,stalk rot,ear rot,and seed rot.As a soil-,seed-,and airborne pathogen,F.verticillioides can survive in soil or plant residue and systemically infect maize via roots,contaminated seed,silks,or external wounds,posing a severe threat to maize production and quality.Infection triggers complex immune responses:induction of defense-response genes,changes in reactive oxygen species,plant hormone levels and oxylipins,and alterations in secondary metabolites such as flavonoids,phenylpropanoids,phenolic compounds,and benzoxazinoid defense compounds.Breeding resistant maize cultivars is the preferred approach to reducing F.verticillioides infection and mycotoxin contamination.Reliable phenotyping systems are prerequisites for elucidating the genetic structure and molecular mechanism of maize resistance to F.verticillioides.Although many F.verticillioides resistance genes have been identified by genome-wide association study,linkage analysis,bulkedsegregant analysis,and various omics technologies,few have been functionally validated and applied in molecular breeding.This review summarizes research progress on the infection cycle of F.verticillioides in maize,phenotyping evaluation systems for F.verticillioides resistance,quantitative trait loci and genes associated with F.verticillioides resistance,and molecular mechanisms underlying maize defense against F.verticillioides,and discusses potential avenues for molecular design breeding to improve maize resistance to F.verticillioides. | Yufang Xu Zhirui Zhang Ping Lu Ruiqi Li Peipei Ma Jianyu Wu Tao Li Huiyong Zhang | 2023 | The Crop Journal2023，11，6： | 0 |

| 12 | Schiff-base silver nanocomplexes formation on natural biopolymer coated mesoporous silica contributed to the improved curative effect on infectious microbes显示文摘Infectious microbes that spread easily in healthcare facilities remain as the severe threat for the public health,especially among immunocompromised populations.Given the intricate problem of dramatic increase in resistance to common biocides,the development of safe and efficient biocide formulated agents to alleviate drug resistance is highly demanding.In this study,Schiff-base ligands were successfully formed on natural biopolymer of epsilon-poly-L-lysine(ε-PL)decorated aldehyde functionalized mesoporous silica SBA-15(CHO-SBA-15)for the selective coordination of silver ions,which was affirmed by various physicochemical methods.Besides the identified broad-spectrum antibacterial activities,the as-prepared Schiff-base silver nanocomplex(CHO-SBA-15/ε-PL/Ag,CLA-1)exhibited an improved inhibitory effect on infectious pathogen growth typified by Escherichia coli and Staphylococcus aureus in comparison with two control silver complexes without Schiff-base conjugates,SBA-15/ε-PL/Ag and CHO-SBA-15/Ag,respectively.In addition,CLA-1 remarkably inhibited the growth of Mycobacterium tuberculosis due to the excellent antimicrobial activity of silver species.Significantly,CLA-1 kills Candida albicans cells,inhibits biofilm formation,and eliminates preformed biofilms,with no development of resistance during continuous serial passaging.The antifungal activity is connected to disruption of bacterial cell membranes and increased levels of intracellular reactive oxygen species.In mouse models of multidrug-resistant C.albicans infection,CLA-1 exhibited efficient in vivo fungicidal efficacy superior to two antifungal drugs,amphotericin B and fluconazole.Moreover,CLA-1 treatment induces negligible toxicity against normal tissues with safety.Therefore,this study reveals the pivotal role of the molecular design of Schiff-base silver nanocomplex formation on biopolymer surface-functionalized silica mesopores as a green and efficient nanoplatform to tackle infectious microbes. | Ling Cai Yanqiang Huang Yuanyuan Duan Qiao Liu Qilan Xu Jia Jia Jianming Wang Qian Tong Peipei Luo Yujie Wen Luming Peng Qian Wu Xudong Hang Huijun Jiang Ping Zhu Yanmei Yang Boshen Zhou Liping Zeng Hongkai Bi Jin Chen | 2021 | Nano Research2021，14，8： | 0 |
| 13 | Mechanism of activation and biased signaling in complement receptor C5aR1显示文摘The complement system plays an important role in the innate immune response to invading pathogens.The complement fragment C5a is one of its important effector components and exerts diverse physiological functions through activation of the C5a receptor 1(C5aR1)and associated downstream G protein andβ-arrestin signaling pathways.Dysfunction of the C5a-C5aR1 axis is linked to numerous inflammatory and immune-mediated diseases,but the structural basis for activation and biased signaling of C5aR1 remains elusive.Here,we present cryo-electron microscopy structures of the activated wild-type C5aR1–Gi protein complex bound to each of the following:C5a,the hexapeptidic agonist C5apep,and the G protein-biased agonist BM213.The structures reveal the landscape of the C5a–C5aR1 interaction as well as a common motif for the recognition of diverse orthosteric ligands.Moreover,combined with mutagenesis studies and cell-based pharmacological assays,we deciphered a framework for biased signaling using different peptide analogs and provided insight into the activation mechanism of C5aR1 by solving the structure of C5aR1I116A mutant–Gi signaling activation complex induced by C089,which exerts antagonism on wild-type C5aR1.In addition,unusual conformational changes in the intracellular end of transmembrane domain 7 and helix 8 upon agonist binding suggest a differential signal transduction process.Collectively,our study provides mechanistic understanding into the ligand recognition,biased signaling modulation,activation,and Gi protein coupling of C5aR1,which may facilitate the future design of therapeutic agents. | Yuying Feng Chang Zhao Yue Deng Heli Wang Liang Ma Sicen Liu Xiaowen Tian Bo Wang Yan Bin Peipei Chen Wei Yan Ping Fu Zhenhua Shao | 2023 | Cell Research2023，33，4： | 0 |
| 14 | Self-healable gels in electrochemical energy storage devices显示文摘In the green energy and carbon-neutral technology,electrochemical energy storage devices have received continuously increasing attention recently.However,due to the unavoidable volume expansion/shrinkage of key materials or irreversible mechanical damages during application,the stability of energy storage and delivery as well as the lifetime of these devices are severely shortened,leading to serious performance degradation or even safety issues.Therefore,the utilization of self-healable gels into electrochemical energy storage devices,such as electrodes,binders,and electrolytes,is proven as an effective method to realize long-term stable operation of these devices via the self-repairing of mechanical and electrochemical characteristics.Herein,this review first summarizes the feature and fabrication of different gels,paying special attention to hydrogels,organohydrogels,and ionogels.Then,basic concepts and figure of merit of self-healable gels are analyzed with a detailed discussion at the healing mechanisms,from reversible dynamic bonds to physical molecular diffusion,and to external healing trigger.Then we introduce all the important parts of electrochemical energy storage devices,which could be replaced by healable gels to enhance the durability,including electrodes,binders,and electrolytes.Finally,the critical challenges and future perspectives regarding the future development of healable gels based high-performance electrochemical energy storage devices or electronics are provided. | Yang Li PeiPei Ding Yuzhe Gu Sheng Qian Yuncong Pang Lele Wang Jiayang Feng Baoguang Liu Qi Wan Ping Li Zhiwei Liu | 2024 | Nano Research2024，17，4： | 0 |
