1Blocking FSH inhibits hepatic cholesterol biosynthesis and reduces serum cholesterol显示文摘Menopause is associated with dyslipidemia and an increased risk of cardio-cerebrovascular disease.The classic view assumes that the underlying mechanism of dyslipidemia is attributed to an insufficiency of estrogen.In addition to a decrease in estrogen, circulating follicle-stimulating hormone (FSH)levels become elevated at menopause.In this study,we find that blocking FSH reduces serum cholesterol via inhibiting hepatic cholesterol biosynthesis.First,epidemiological results show that the serum FSH levels are positively correlated with the serum total cholesterol levels,even after adjustment by considering the effects of serum estrogen,in addition,the prevalence of hypercholesterolemia is significantly higher in peri-menopausal women than that in premenopausal women.Furthermore,we generated a mouse model of FSH elevation by intraperitoneally injecting exogenous FSH into ovariectomized (OVX)mice,in which a normal level of estrogen (E2)was maintained by exogenous supplementation. Consistently,the results indicate that FSH,independent of estrogen,increases the serum cholesterol level in this mouse model. Moreover,blocking FSH signaling by anti-FSHβ antibody or ablating the FSH receptor (FSHR)gene could effectively prevent hypercholesterolemia induced by FSH injection or high-cholesterol diet feeding.Mechanistically,FSH,via binding to hepatic FSHRs, activates the Gi2α/β-arrestin-2/Akt pathway and subsequently inhibits the binding of FoxO1 with the SREBP-2 promoter,thus preventing FoxO1 from repressing SREBP-2 gene transcription.This effect,in turn,results in the upregulation of SREBP-2,which drives HMGCR nascent transcription and de novo cholesterol biosynthesis,leading to the increase of cholesterol accumulation.This study uncovers that blocking FSH signaling might be a new strategy for treating hypercholesterolemia during menopause, particularly for women in peri-menopause characterized by FSH elevation only.Yanjing Guo Meng Zhao Tao Bo Shizhan Ma Zhongshang Yuan Wenbin Chen Zhao He Xu Hou Jun Liu Zhenhai Zhang Qiang Zhu Qiangxiu Wang Xiaoyan Lin Zhongli Yang Min Cui Lu Liu Yujie Li Chunxiao Yu Xiaoyi Qi Qian Wang Haiqing Zhang Qingbo Guan Lifang Zhao Shimeng Xuan Huili Yan Yanliang Lin Li Wang Qihang Li Yongfeng Song Ling Gao Jiajun Zhao 2019Cell Research2019,29,2:16
2A comparative analysis of five global cropland datasets in China显示文摘Accurate information of cropland area and spatial location is critical for studies of national food security, global environmental change, terrestrial ecosystem geophysics and the geochemical cycle. In this paper, we compared five global cropland datasets in circa 2010 of China from in terms of cropland area and spatial location, including Global Land30, FROM-GLC, Glob Cover, MODIS Collection 5, and MODIS Cropland. The results showed that the accuracies of cropland area and spatial location of Globe Land30 were higher than the other four products. The cropland areas of the five products varied in most of the provinces. Compared with the statistical data, the best goodness of fit was obtained using Globe Land30, followed by MODIS Collection 5 and FROM-GLC, with MODIS Cropland and Glob Cover having the poorer accuracies. Regarding the spatial location of cropland, Globe Land30 achieved the best accuracy, followed by FROM-GLC and MODIS Collection 5, with Glob Cover and MODIS Cropland having the poorer accuracies. In addition, the spatial agreement of the five datasets was reduced from agricultural production area to pastoral area and significantly affected by elevation and slope factors. Although the spatial resolution of MODIS Collection 5 was the lowest, accuracies of the cropland area and spatial location were better than those of Glob Cover and MODIS Cropland. Therefore, high spatial resolution remote sensing images can help to improve the accuracy of the dataset during land cover mapping, while it is also important to select a suitable classification method. Furthermore, in northwestern and southeastern China, spectral mixing pixels are universal because of the complicated landscape and fragmentized topography and result in uncertainty and poor consistency when using the five products. Therefore, these regions require additional attention in future cropland mapping studies.LU Miao WU WenBin ZHANG Li LIAO AnPing PENG Shu TANG HuaJun 2016Science China(Information Sciences)2016,59,12:15
3Cropland redistribution to marginal lands undermines environmental sustainability显示文摘Cropland redistribution to marginal land has been reported worldwide;however,the resulting impacts on environmental sustainability have not been investigated sufficiently.Here we investigated the environmental impacts of cropland redistribution in China.As a result of urbanization-induced loss of high-quality croplands in south China(~8.5 t ha^(-1)),croplands expanded to marginal lands in northeast(~4.5 t ha^(-1)) and northwest China(~2.9 t ha^(-1)) during 1990-2015 to pursue food security.However,the reclamation in these low-yield and ecologically vulnerable zones considerably undermined local environmental sustainability,for example increasing wind erosion(+3.47%),irrigation water consumption(+34.42%),fertilizer use(+20.02%) and decreasing natural habitats(-3.11%).Forecasts show that further reclamation in marginal lands per current policies would exacerbate environmental costs by 2050.The future cropland security risk will be remarkably intensified because of the conflict between food production and environmental sustainability.Our research suggests that globally emerging reclamation of marginal lands should be restricted and crop yield boost should be encouraged for both food security and environmental benefits.Wenhui Kuang Jiyuan Liu Hanqin Tian Hao Shi Jinwei Dong Changqing Song Xiaoyong Li Guoming Du Yali Hou Dengsheng Lu Wenfeng Chi Tao Pan Shuwen Zhang Rafiq Hamdi Zherui Yin Huimin Yan Changzhen Yan Shixin Wu Rendong Li Jiuchun Yang Yinyin Dou Wenbin Wu Liqiao Liang Bao Xiang Shiqi Yang 2022National Science Review2022,9,1:13
4Effects of bamboo vinegar powder on growth performance and mRNA expression levels of interleukin-10,interleukin-22,and interleukin-25 in immune organs of weaned piglets显示文摘The aim of this study was to explore the effects of bamboo vinegar powder on growth performance,diarrhea situation and mRNA expression levels of cytokines i.e., interleukin-10(IL-10), interleukin-22(IL-22), and interleukin-25(IL-25) in immune organs of weaned piglets, and to accumulate theoretical data for the application of bamboo vinegar powder in weaned piglet production. Forty-five crossbred(Duroc × Landrace × Yorkshire, all male) weaned piglets with similar body weight(6.74 ± 0.17 kg) at 31 days of age were randomly assigned to 5 treatments with 3 replicates per treatment and 3 piglets in each replicate. The five treatments were as follows: CON(a basal diet), ANT(the basal diet + 0.12% antibiotics),BV1(the basal diet + 0.1% bamboo vinegar powder), BV5(the basal diet + 0.5% bamboo vinegar powder),BV10(the basal diet + 1.0% bamboo vinegar powder). This experiment lasted 35 days. The growth performance and diarrhea situation were recorded. The relative mRNA expression levels of IL-10, IL-22 and IL-25 in liver, spleen, duodenum and mesenteric lymph nodes were detected by real-time PCR. Feed:gain of BV5 was significantly lower than that of CON(P < 0.05). In comparison with CON, diarrhea rate and diarrhea index of BV1 and BV5 all tended to decrease(P < 0.1). Compared with CON, mRNA expression level of IL-10 in liver of ANT tended to be lower(P < 0.1) and these of BV1, BV5 and BV10 were significantly reduced(P < 0.05). The mRNA expression levels of IL-10 in duodenum of ANT, BV1, BV5 and BV10 were all lower than those of CON, of which BV10 had significantly decreased IL-10 mRNA expression in duodenum(P < 0.05). The mRNA expression levels of IL-22 in duodenum of ANT, BV1, BV5 and BV10 all tended to be inhibited compared with CON(P < 0.1). With the increase of bamboo vinegar powder dosage, mRNA expression levels of IL-25 in spleen and mesenteric lymph nodes of BV1, BV5 and BV10 tended to be up-regulated. Overall, bamboo vinegar powder could improve growth performance,and regulate mRNA expression levels of IL-10, IL-22 and IL-25 in immune organs of weaned piglets. The dosage at 0.5% showed optimum effects.Yongjiu Huo Zhengxu Liu Han Xuan Chunbin Lu Lihuai Yu Wenbin Bao Guoqi Zhao 2016Animal Nutrition2016,,2:11

6Observer-based adaptive consensus control for nonlinear multi-agent systems with time-delay显示文摘In this paper, we consider the observer-based adaptive consensus tracking problem for a class of nonlinear time-delay multi-agent systems in the presence of input saturation. Under the assumption that the communication topology is directed and connected, a distributed adaptive consensus controller is developed based on the dynamic surface control technique. By constructing the nonlinear observer, the unmeasurable agents dynamics can be estimated. Input saturation problem is solved by a smooth function combined with an auxiliary variable. With the help of prescribed performance functions, the synchronization errors converge to the prescribed sets, which are characterized as a neighborhood of zero. According to Lyapunov stability theory, it is shown that with the proposed distributed consensus tracking approach, the consensus errors are cooperatively semi-globally uniformly ultimately bounded. Finally, a simulation example is provided to show the effectiveness of the proposed algorithm.Wenbin XIAO Liang CAO Hongyi LI Renquan LU 2020Science China(Information Sciences)2020,63,3:10

10Polygenetic Mineralization of the Early ProterozoicTongkuangyu Metaporphyry Copper Deposit inthe Zhongtiao Mountains,Shanxi Province显示文摘The Tongkuangyu metaporphyry copper deposit formed in the Early Proterozoic is tectonically located in the northern part of the Zhongtiao X -type palaeorift depression, on the southern margin of the North China platform. The genesis of the deposit has long been a hot subject of research of geologists working on mineral deposits. By means of the protolith reconstruction and fluid inclusion and isotope studies of host rocks of the deposits, the authors hold that this deposit is the product of combined exogenic, endogenic and metamorphic processes. Its formation mainly involved the following four stages: (1) the stage of formation of Mg- and Fe-rich tuffaceous variegated cupriferous sand-shale and K-rich biomodal volcanic rocks; (2) the early stage of formation of the metaporphyry copper deposit; (3) the stage of formation of the metaporphyry copper deposit; and (4) the stage of reworking of the metaporphyry copper deposit.CHEN Wenming ZHANG Chengxin LU Jiren DANG Zefa LI Shuping CUI Wenbin NING Yuan 1998Acta Geologica Sinica(English Edition)1998,72,2:7
11Thermal Shock-Activated Spontaneous Growing of Nanosheets for Overall Water Splitting显示文摘Nanomaterials based on nickel foam(NF) have been widely applied in energy conversion and storage field.Traditional synthesis methods such as hydrothermal method which is dangerous and high cost limited the scalable developments.Herein,we report a fast,simple,and low-cost synthesis method of nanomaterials based on NF by Joule-heating and water soaking treatment.Thin carbon-coated CoS on NF(NF-C/CoS) was synthesized by Joule-heating for a few seconds with rapid cooling.And then,NF-C/CoS/NiOOH with core-shell heterostructure was fabricated by soaking treatment of NF-C/CoS in water on which NiOOH nanosheets grew spontaneously.The formation mechanism is proposed that the coordination complex precursor converts into C/CoS on NF driven by Joule-heating,and the nickel on the surface of NF is activated to form metastable nickel simultaneously.The metastable nickel reacting with water leads to the formation of NiOOH,and the induction of CoS makes NiOOH grow continuously.This synthesis technology provides a new route to manufacture NF-based nanostructures,and the as-fabricated NF-C/CoS/NiOOH exhibits great potential as electrocatalyst for oxygen evolution reaction and hydrogen evolution reaction.Han Wu Qi Lu Jinfeng Zhang Jiajun Wang Xiaopeng Han Naiqin Zhao Wenbin Hu Jiajun Li Yanan Chen Yida Deng 2020Nano-Micro Letters2020,12,11:6
12Characterization of event-related potentials in obsessive compulsive disorder patients: Comparison with depression and generalized anxiety disorder patients显示文摘BACKGROUND: Study results of event-related potential in obsessive compulsive disorder (OCD) remain controversial, potentially as a result of different instruments utilized and their differing technical characteristics. OBJECTIVE: To investigate the differences in several common event-related potentials, i.e. contingent negative variations, P300, and mismatch negativity (MMN), in OCD patients, depression patients, generalized anxiety disorder (GAD) patients, and healthy controls. DESIGN, TIME AND SETTING: A case-control study was performed in the Department of Electrophysiology, Shanghai Mental Health Center from May 2002 to December 2005. PARTICIPANTS: A total of 38 OCD patients, 20 depression patients, and 18 GAD patients, who were diagnosed according to the criteria of Chinese Classification of Mental Disorders (Version 3), formulated by the Chinese Psychiatry Association, were selected from the Outpatient Department o Shanghai Mental Health Center. Patients with two or more the above diseases were excluded. In addition, 28 healthy people, gender and age matched, were selected as controls. METHODS: Contingent negative variations, P300, and MMN were recorded by a Nicolet Spirit Instrument. All electrodes were attached at Cz according to the International 10-20 system, with the mastoid leads as reference and Fpz as ground. MAIN OUTCOME MEASURES: Amplitude and latency of contingent negative variations, P300, and MMN. RESULTS: The contingent negative variations, P300, and MMN were different (P < 0.01). OCD patients showed an increased M1 amplitude compared with controls, depression, and GAD patients (P < 0.01). Target P300 amplitudes were significantly lower in OCD, depression, and GAD patients compared with controls (P < 0.01). Moreover, N2 latency and latency of MMN were prolonged in OCD and depression groups compared with controls (P < 0.05). CONCLUSION: Event-related potentials were different in depression, GAD, and OCD patients and healthy controls. In particular, OCD patients exhibited unique characteristics.Yingzhi Lu Wenbin Zong Hanzhen Dong Faxin Wang Jinyu PU Xingshi Chen Yunxiang Tang 2010Neural Regeneration Research2010,5,12:5
13Application of Bis[2-(3,4-epoxycyclohexyl)ethyl]octamethyltetrasiloxane in the Preparation of a Photosensitive Resin for Stereolithography 3D Printing显示文摘Bis[2-(3,4-epoxycyclohexyl)ethyl]octamethyltetrasiloxane is also called diepoxycyclohexylethyl octamethyltetrasiloxane. In the present paper, diepoxycyclohexylethyl octamethyltetrasiloxane was synthesized, and the synthesized product was characterized by FTIR and 1 HMR. The synthesized product was compounded with some acrylates and an expoxide as well as photoinitiators to obtain a 3D printing stereolithography resin(3DSLR111). The properties of 3DSLR111 and its UV-cured samples were investigated by some instruments and equipments. The experimental results show that the critical exposure(Ec) of 3DSLR111 is 10.1 mJ/cm^2, its penetration depth(Dp) is 0.15 mm, and its viscosity at 30 ℃ is 319 mPa·s. Some samples were printed with 3DSLR111, and their linear shrinkage and warping factor were evaluated. The linear shrinkage and the curl distortion factor are less than 0.80% and 7.30%, respectively, which indicates that the sample printed with 3DSLR111 has high accuracy, and that the synthesized diepoxycyclohexylethyl octamethyltetrasiloxane can be well applied to the preparation of the photosensitive resin for stereolithography 3D printing.黄笔武 HAN Linlin WU Baolin CHEN Hao ZHOU Wenbin LU Zhenting 2019Journal of Wuhan University of Technology(Materials Science)2019,34,6:4
14Preparation of a Novel Cationic Photosensitive Resin(3D-SLR01) for Stereolithography 3D Printing and Determination of Its Some Properties显示文摘A novel cationic photosensitive resin(3 DSLR-01) for stereolithography 3 D printing was prepared with 3,4-epoxycyclohexylmethyl-3’,4’-epoxycyclohexane carboxylate(2021 P),1,4-cyclohexanedimethanol glycidyl ether(JX-026), diglycidyl 4,5-epoxycyclohexane-1,2-dicarboxylate(S-186), polycaprolactone polyol(Polyol-0305), novolac epoxy resin(F-51), bis(3-ethyl-3-oxetanylmethyl) ether(S-221) and a mixture of triarylsulfonium hexafluoroantimonate salts solution(UVI-6976). The properties of the photosensitive resin and its UV-cured films were investigated by some instruments and equipment.The experimental results show that the critical exposure(Ec) of the photosensitive resin is 16.3 mJ/cm^2, the penetration depth(Dp) is 0.14 mm, and the optical property of the photosensitive resin is excellent. Rectangle plates were printed by using a stereolithography apparatus(HRPL-150 A) with the photosensitive resin as the manufacturing material, and the shrinkage rates of the plates were less than 0.60%, which showed that the accuracy of the manufactured plates was very high.黄笔武 WU Baolin HAN Linlin LU Zhenting ZHOU Wenbin 2019Journal of Wuhan University of Technology(Materials Science)2019,34,4:4
15Performance enhancement of sandwich panels with honeycomb–corrugation hybrid core显示文摘The concept of combining metallic honeycomb with folded thin metallic sheets(corrugation) to construct a novel core type for lightweight sandwich structures is proposed. The honeycomb–corrugation hybrid core is manufactured by filling the interstices of aluminum corrugations with precision-cut trapezoidal aluminum honeycomb blocks, bonded together using epoxy glue. The performance of such hybrid-cored sandwich panels subjected to out-of-plane compression, transverse shear, and three-point bending is investigated, both experimentally and numerically. The strength and energy absorption of the sandwich are dramatically enhanced, compared to those of a sandwich with either empty corrugation or honeycomb core. The enhancement is induced by the beneficial interaction effects of honeycomb blocks and folded panels on improved buckling resistance as well as altered crushing modes at large plastic deformation.The present approach provides an effective method to further improve the mechanical properties of conventional honeycomb-cored sandwich constructions with low relative densities.Bin Han Wenbin Wang Zhijia Zhang Qiancheng Zhang Feng Jin Tianjian Lu 2016Theoretical & Applied Mechanics Letters2016,6,1:4
162022 Chinese expert consensus and guidelines on clinical management of toxicity in anti-CD19 chimeric antigen receptor T-cell therapy for B-cell non-Hodgkin lymphoma显示文摘Adoptive cellular immunotherapy with chimeric antigen receptor(CAR)T cells has emerged as a novel modality for treating relapsed and/or refractory B-cell non-Hodgkin lymphoma(B-NHL).With increasing approval of CAR T-cell products and advances in CAR T cell therapy,CAR T cells are expected to be used in a growing number of cases.However,CAR T-cell-associated toxicities can be severe or even fatal,thus compromising the survival benefit from this therapy.Standardizing and studying the clinical management of these toxicities are imperative.In contrast to other hematological malignancies,such as acute lymphoblastic leukemia and multiple myeloma,anti-CD19 CAR T-cell-associated toxicities in B-NHL have several distinctive features,most notably local cytokine-release syndrome(CRS).However,previously published guidelines have provided few specific recommendations for the grading and management of toxicities associated with CAR T-cell treatment for B-NHL.Consequently,we developed this consensus for the prevention,recognition,and management of these toxicities,on the basis of published literature regarding the management of anti-CD19 CAR T-cell-associated toxicities and the clinical experience of multiple Chinese institutions.This consensus refines a grading system and classification of CRS in B-NHL and corresponding measures for CRS management,and delineates comprehensive principles and exploratory recommendations for managing anti-CD19 CAR T-cell-associated toxicities in addition to CRS.Ping Li Yang Liu Yun Liang Jian Bo Sujun Gao Yongxian Hu Yu Hu He Huang Xiaojun Huang Hongmei Jing Xiaoyan Ke Jianyong Li Yuhua Li Qifa Liu Peihua Lu Heng Mei Ting Niu Yongping Song Yuqin Song Liping Su Sanfang Tu Jianxiang Wang Depei Wu Zhao Wang Kailin Xu Zhitao Ying Qingming Yang Yajing Zhang Fengxia Shi Bin Zhang Huilai Zhang Xi Zhang Mingfeng Zhao Weili Zhao Xiangyu Zhao Liang Huang Jun Zhu Wenbin Qian Weidong Han Aibin Liang 2023Cancer Biology & Medicine2023,20,2:3
17A rapid and operator-safe powder approach for latent fingerprint detection using hydrophilic Fe3O4@SiO2-CdTe nanoparticles显示文摘A new kind of bifunctional magnetic-fluorescent nanoparticles(NPs)with abundant carboxyls on the surface has been prepared by covalently combining glutathiose(GSH)-modified CdTe quantum dots(QDs)with Fe3O4@SiO2NPs.The silica-coated Fe3O4NPs were functionalized with amino groups by(3-aminopropyl)triethoxysilane to provide Fe3O4@SiO2-NH2NPs,which was then chemically conjugated with GSH-modified CdTe QDs to form bifunctional magnetic-fluorescent NPs,Fe3O4@SiO2-NH-CO-CdTe-QDs NPs.The properties and morphologies of Fe3O4@SiO2-NH-CO-CdTe-QDs NPs were investigated by FTIR,X-ray diffraction,transmission electron microscopy(TEM),absorption and fluorescence spectroscopy and vibrating sample magnetometry.TEM images display that Fe3O4@SiO2-NH-CO-CdTe-QDsNPs possess spherical core-shell structure with a uniform size about 50 nm.The bifunctional NPs were found to exhibit good magnetic and strong fluorescent properties favorable for their application in the detection of latent fingerprints.Furthermore,the carboxyls on the surface of NPs have good absorptions with water in air and the residues of fingerprints so as to not only avoid dust flying to protect the health of operators,but also improve the efficiency of detection.Zhaolei Wang Xue Jiang Wenbin Liu Guolin Lu Xiaoyu Huang 2019Science China Chemistry2019,62,7:3
18Stable perovskite solar cells with efficiency of 22.6%via quinoxaline-based polymeric hole transport material显示文摘Poor stability of spiro-OMe TAD hole transport materials(HTMs)with dopant is a major obstacle for the commercialization of perovskite solar cells(pero-SCs).Herein,we demonstrate a series of quinoxaline-based D-A copolymers PBQ5,PBQ6 and PBQ10 as the dopant-free polymer HTMs for high performance pero-SCs.The D-A copolymers are composed of fluorothienyl benzodithiophene(BDTT)as D-unit,difluoroquinoxaline(DFQ)with different side chains as A-unit,and thiophene asπ-bridge,where the side chains on the DFQ unit are bi-alkyl for PBQ5,bi-alkyl-fluorothienyl for PBQ6,and alkoxyl for PBQ10.All the three copolymers are adopted as the dopant-free HTM in the pero-SCs.The planar n-i-p structured pero-SCs based on(FAPb I_(3))_(0.98)(MAPb Br_(3))_(0.02)with PBQ6 HTM demonstrated the high power conversion efficiency(PCE)of 22.6%with Vocof1.13 V and FF of 80.8%,which is benefitted from the suitable energy level and high hole mobility of PBQ6.The PCE of 22.6%is the highest efficiency reported in the n-i-p structured pero-SCs based on dopant-free D-A copolymer HTM.In addition,the peroSCs show significantly enhanced ambient,thermal and light-soaking stability compared with the devices with traditional spiroOMe TAD HTM.Chenxing Lu Can Zhu Lei Meng Chenkai Sun Wenbin Lai Shucheng Qin Jinyuan Zhang Wenchao Huang Jiaqi Du Yiyang Wang Yongfang Li 2021Science China Chemistry2021,64,11:2
19Analytical design of effective thermal conductivity for fluid-saturated prismatic cellular metal honeycombs显示文摘A comparative optimal design of fluid-saturated prismatic cellular metal honeycombs(PCMHs) having different cell shapes is presented for thermal management applications. Based on the periodic topology of each PCMH, a unit cell(UC) for thermal transport analysis was selected to calculate its effective thermal conductivity. Without introducing any empirical coefficient, we modified and extended the analytical model of parallel–series thermal–electric network to a wider porosity range(0.7 ~ 0.98) by considering the effects of two-dimensional local heat conduction in solid ligaments inside each UC. Good agreement was achieved between analytical predictions and numerical simulations based on the method of finite volume. The concept of ligament heat conduction efficiency(LTCE) was proposed to physically explain the mechanisms underlying the effects of ligament configuration on effective thermal conductivity(ETC).Based upon the proposed theory, a construct strategy was developed for designing the ETC by altering the equivalent interaction angle with the direction of heat flow: relatively small average interaction angle for thermal conduction and relatively large one for thermal insulation.Wenbin Wang Xiaohu Yang Bin Han Qiancheng Zhang Xiangfei Wang Tianjian Lu 2016Theoretical & Applied Mechanics Letters2016,6,2:2
20Impeding the combination of astrocytic ASCT2 and NLRP3 by talniflumate alleviates neuroinflammation in experimental models of Parkinson's disease显示文摘Alanine-serine-cysteine transporter 2(ASCT2)is reported to participate in the progression of tumors and metabolic diseases.It is also considered to play a crucial role in the glutamate-glutamine shuttle of neuroglial network.However,it remains unclear the involvement of ASCT2 in neurological diseases such as Parkinson’s disease(PD).In this study,we demonstrated that high expression of ASCT2 in the plasma samples of PD patients and the midbrain of MPTP mouse models is positively correlated with dyskinesia.We further illustrated that ASCT2 expressed in astrocytes rather than neurons significantly upregulated in response to either MPP+or LPS/ATP challenge.Genetic ablation of astrocytic ASCT2 alleviated the neuroinflammation and rescued dopaminergic(DA)neuron damage in PD models in vitro and in vivo.Notably,the binding of ASCT2 to NLRP3 aggravates astrocytic inflammasometriggered neuroinflammation.Then a panel of 2513 FDA-approved drugs were performed via virtual molecular screening based on the target ASCT2 and we succeed in getting the drug talniflumate.It is validated talniflumate impedes astrocytic inflammation and prevents degeneration of DA neurons in PD models.Collectively,these findings reveal the role of astrocytic ASCT2 in the pathogenesis of PD,broaden the therapeutic strategy and provide a promising candidate drug for PD treatment.Yang Liu Ting Liu Yuanzhang Zhou Wenjie Li Min Wang Nanshan Song Wenbin Zhang Jingwei Jiang Shengtao Yuan Jianhua Ding Gang Hu Ming Lu 2023Acta Pharmaceutica Sinica B2023,13,2:2
