| 1 | Baicalin induces ferroptosis in bladder cancer cells by downregulating FTH1显示文摘Ferroptosis is a non-apoptotic regulated cell death caused by iron accumulation and subsequent lipid peroxidation.Currently,the therapeutic role of ferroptosis on cancer is gaining increasing interest.Baicalin an active component in Scutellaria baicalensis Georgi with anticancer potential various cancer types;however,the effects of baicalein on bladder cancer and the underlying molecular mechanisms remain largely unknown.In the study,we investigated the effect of baicalin on bladder cancer cells5637 and KU-19-19.As a result,we show baicalin exerted its anticancer activity by inducing apoptosis and cell death in bladder cancer cells.Subsequently,we for the first time demonstrate baicalin-induced ferroptotic cell death in vitro and in vivo,accompanied by reactive oxygen species(ROS) accumulation and intracellular chelate iron enrichment.The ferroptosis inhibitor deferoxamine but not necrostatin-1,chloroquine(CQ),N-acetyl-L-cysteine,L-glutathione reduced,or carbobenzoxy-valyl-alanyl-aspartyl-[O-methyl]-fluoromethylketone(Z-VAD-FMK) rescued baicalin-induced cell death,indicating ferroptosis contributed to baicalin-induced cell death.Mechanistically,we show that ferritin heavy chain1(FTH1) was a key determinant for baicalin-induced ferroptosis.Overexpression of FTH1 abrogated the anticancer effects of baicalin in both 5637 and KU19-19 cells.Taken together,our data for the first time suggest that the natural product baicalin exerts its anticancer activity by inducing FTH1-dependent ferroptosis,which will hopefully provide a prospective compound for bladder cancer treatment. | Na Kong Xiaying Chen Jiao Feng Ting Duan Shuiping Liu Xueni Sun Peng Chen Ting Pan Lili Yan Ting Jin Yu Xiang Quan Gao Chengyong Wen Weirui Ma Wencheng Liu Mingming Zhang Zuyi Yang Wengang Wang Ruonan Zhang Bi Chen Tian Xie Xinbing Sui Wei Tao | 2021 | Acta Pharmaceutica Sinica B2021,11,12: | 23 |
| 2 | Gut microbiota contributes to the distinction between two traditional Chinese medicine syndromes of ulcerative colitis显示文摘BACKGROUND Ulcerative colitis(UC)is considered to be closely associated with alteration of intestinal microorganisms.According to the traditional Chinese medicine(TCM)theory,UC can be divided into two disease syndromes called Pi-Xu-Shi-Yun(PXSY)and Da-Chang-Shi-Re(DCSR).The relationships among gut microbiota,TCM syndromes,and UC pathogenesis have not been well investigated.AIM To investigate the role of gut microbiota in UC and the distinction of microbiota dysbiosis between PXSY and DCSR syndromes.METHODS From May 2015 to February 2016,UC patients presenting to LongHua Hospital who met the established inclusion and exclusion criteria were enrolled in this retrospective study.Fresh stool specimens of UC patients with PXSY or DCSR were collected.The feces of the control group came from the health examination population of Longhua Hospital.The composition of gut bacterial communities in stool samples was determined by the pyrosequencing of 16S ribosomal RNA.The high-throughput sequencing reads were processed with QIIME,and biological functions were predicted using Phylogenetic Investigation of Communities by Reconstruction of Unobserved States.RESULTS The composition of gut bacterial communities in 93 stool samples(30 healthy controls,32 patients with PXSY syndrome,and 31 patients with DCSR syndrome)was determined by the pyrosequencing of 16S ribosomal RNA.Beta diversity showed that the composition of the microbiota was different among the three groups.At the family level,Porphyromonadaceae,Rikeneliaceae,and Lachnospiraceae significantly decreased while Enterococcus,Streptococcus,and other potential pathogens significantly increased in UC patients compared to healthy subjects.At the genus level,Parabacteroides,Dorea,and Ruminococcus decreased while Faeca-libacterium showed increased abundance in UC compared to healthy controls.Five differential taxa were identified between PXSY and DCSR syndromes.At the genus level,a significantly increased abundance of Streptococcus was observed in DCSR patients,while Lachnoclostridium increased in PXSY patients.The differential functional pathways of the gut microbiome between the PXSY and DCSR groups mainly included lipid metabolism,immunity,and the metabolism of polypeptides.CONCLUSION Our study suggests that the gut microbiota contributes to the distinction between the two TCM syndromes of UC. | Ya-Li Zhang Li-Ting Cai Jun-Yi Qi Yun-Zheng Lin Yan-Cheng Dai Na Jiao You-Lan Chen Lie Zheng Bei-Bei Wang Li-Xin Zhu Zhi-Peng Tang Rui-Xin Zhu | 2019 | World Journal of Gastroenterology2019,25,25: | 19 |
| 3 | A review of ecological restoration techniques in fluvial rivers显示文摘Rivers play an important role in people's living and agricultural production,however,intense human activities have broken the original ecological balance,and affected structures and functions of the river ecosystem.To restore the damaged river ecosystem back to a healthy status,effective ecological restoration measures need to be implemented.The main problems that the damaged rivers face are either the locally altered hydrological processes affected by construction of hydraulic facilities,or the deterioration of water quality resulted from pollution emissions,or both.In this study,ecological restoration techniques of the rivers affected by engineering control or pollution are reviewed respectively.In addition,three kinds of methods,i.e.physical,chemical and biological-ecological methods are introduced in details for the rivers affected by water pollution.At present,the development of river restoration techniques shows the following trends:1) the scale of ecological restoration is becoming larger;2) ecological restoration measures are required to meet multiple objectives;and 3) the management of water environment is changing from water quality management to aquatic ecosystem management. | Baozhu Pan Jianping Yuan Xinhua Zhang Zhaoyin Wang Jiao Chen Jinyou Lu Wenjun Yang Zhiwei Li Na Zhao Mengzhen Xu | 2016 | International Journal of Sediment Research2016,31,2: | 18 |
| 4 | Relative importance of climate factors and human activities in impacting vegetation dynamics during 2000–2015 in the Otindag Sandy Land,northern China显示文摘In recent years, there has been increasing research interests in differentiating the relative importance of climate factors and human activities in impacting vegetation dynamics. In this study, based on residual trend method, we used MOD13A3(MODIS vegetation index product), MCD12Q1(MODIS land cover product) and meteorological datasets to differentiate the relative importance of climate factors and human activities in impacting vegetation dynamics during 2000–2015 in the Otindag Sandy Land, northern China. Results show that during the study period(2000–2015), the overall vegetation condition had improved in the Otindag Sandy Land. The driving forces of vegetation dynamics differed spatially in the whole study area over the study period. The area with vegetation degradation solely resulted from human activities accounted for 8.23% of the study area, while the area with vegetation degradation resulted from others(including climate factors and combination of climate factors and human activities) occupied 1.53%. The area with vegetation recovery benefitted from human activities occurred over 26.02% of the study area; the area benefitted from climate factors accounted for 23.69%; and the area benefitted from both climate factors and human activities occupied 37.74%. All in all, impacts of climate factors and human activities on vegetation dynamics varied at the county/city/banner scales and locality-specific measures should be adopted to protect the environments. | MA Wenyong WANG Xunming ZHOU Na JIAO Linlin | 2017 | Journal of Arid Land2017,9,4: | 11 |
| 5 | A fundamental theorem for eco-environmental surface modelling and its applications显示文摘We propose a fundamental theorem for eco-environmental surface modelling(FTEEM) in order to apply it into the fields of ecology and environmental science more easily after the fundamental theorem for Earth’s surface system modeling(FTESM). The Beijing-Tianjin-Hebei(BTH) region is taken as a case area to conduct empirical studies of algorithms for spatial upscaling, spatial downscaling, spatial interpolation, data fusion and model-data assimilation, which are based on high accuracy surface modelling(HASM), corresponding with corollaries of FTEEM. The case studies demonstrate how eco-environmental surface modelling is substantially improved when both extrinsic and intrinsic information are used along with an appropriate method of HASM. Compared with classic algorithms, the HASM-based algorithm for spatial upscaling reduced the root-meansquare error of the BTH elevation surface by 9 m. The HASM-based algorithm for spatial downscaling reduced the relative error of future scenarios of annual mean temperature by 16%. The HASM-based algorithm for spatial interpolation reduced the relative error of change trend of annual mean precipitation by 0.2%. The HASM-based algorithm for data fusion reduced the relative error of change trend of annual mean temperature by 70%. The HASM-based algorithm for model-data assimilation reduced the relative error of carbon stocks by 40%. We propose five theoretical challenges and three application problems of HASM that need to be addressed to improve FTEEM. | Tianxiang YUE Na ZHAO Yu LIU Yifu WANG Bin ZHANG Zhengping DU Zemeng FAN Wenjiao SHI Chuanfa CHEN Mingwei ZHAO Dunjiang SONG Shihai WANG Yinjun SONG Changqing YAN Qiquan LI Xiaofang SUN Lili ZHANG Yongzhong TIAN Wei WANG Ying’an WANG Shengnan MA Hongsheng HUANG Yimin LU Qing WANG Chenliang WANG Yuzhu WANG Ming LU Wei ZHOU Yi LIU Xiaozhe YIN Zong WANG Zhengyi BAO Miaomiao ZHAO Yapeng ZHAO Yimeng JIAO Ufra NASEER Bin FAN Saibo LI Yang YANG John PWILSON | 2020 | Science China Earth Sciences2020,63,8: | 7 |

| 7 | CRISPR/Cas9-mediated VvPR4b editing decreases downy mildew resistance in grapevine(Vitis vinifera L.)显示文摘Downy mildew of grapevine(Vitis vinifera L.),caused by the oomycete pathogen Plasmopara viticola,is one of the most serious concerns for grape production worldwide.It has been widely reported that the pathogenesis-related 4(PR4)protein plays important roles in plant resistance to diseases.However,little is known about the role of PR4 in the defense of grapevine against P.viticola.In this study,we engineered loss-of-function mutations in the VvPR4b gene from the cultivar“Thompson Seedless”using the CRISPR/Cas9 system and evaluated the consequences for downy mildew resistance.Sequencing results showed that deletions were the main type of mutation introduced and that no off-target events occurred.Infection assays using leaf discs showed that,compared to wild-type plants,the VvPR4b knockout lines had increased susceptibility to P.viticola.This was accompanied by reduced accumulation of reactive oxygen species around stomata.Measurement of the relative genomic abundance of P.viticola in VvPR4b knockout lines also demonstrated that the mutants had increased susceptibility to the pathogen.Our results confirm that VvPR4b plays an active role in the defense of grapevine against downy mildew. | Meng-Yuan Li Yun-Tong Jiao Yu-Ting Wang Na Zhang Bian-Bian Wang Rui-Qi Liu Xiao Yin Yan Xu Guo-Tian Liu | 2020 | Horticulture Research2020,7,1: | 6 |

| 9 | Using ultrasound to improve the sequential post-synthesis modification method for making mesoporous Y zeolites显示文摘Mesoporous Y zeolites were prepared by the sequential chemical dealumination(using chelating agents such as ethylenediaminetetraacetic acid,H EDTA,and citric acid aqueous solutions)and alkaline desilication(using sodium hydroxide,NaOH,aqueous solutions)treatments.Specifically,the ultrasound-assisted alkaline treatment(i.e.,ultrasonic treatment)was proposed as the alternative to conventional alkaline treatments which are performed under hydrothermal conditions.In comparison with the hydrothermal alkaline treatment,the ultrasonic treatment showed the comparatively enhanced efficiency(with the reduced treatment time,i.e.,5 min vs.30 min,all with 0.2 mol·L NaOH at 65°C)in treating the dealuminated Y zeolites for creating mesoporosity.For example,after the treatment of a dealuminated zeolite Y(using 0.1 mol·L H EDTA at 100°C for 6 h),the ultrasonic treatment produced the mesoporous zeolite Y with the specific external surface area()of 160 m·g and mesopore volume()of 0.22 cm·g,being slightly higher than that by the conventional method(i.e.,=128 m·g and=0.19 cm·g).The acidic property and catalytic activity(in catalytic cracking of-octane)of mesoporous Y zeolites obtained by the two methods were comparable.The ultrasonic desilication treatment was found to be generic,also being effective to treat the dealuminated Y zeolites by citric acid.Additionally,the first step of chemical dealumination treatment was crucial to enable the effective creation of mesopores in the parent Y zeolite(with a silicon-to-aluminium ratio,Si/Al=2.6)regardless of the subsequent alkaline desilication treatment(i.e.,ultrasonic or hydrothermal).Therefore,appropriate selection of the condition of the chemical dealumination treatment based on the property of parent zeolites,such as Si/Al ratio and crystallinity,is important for making mesoporous zeolites effectively. | Rongxin Zhang Peinan Zhong Hamidreza Arandivan Yanan Guan Jinmin Liu Na Wang Yilai Jiao Xiaolei Fan | 2020 | Frontiers of Chemical Science and Engineering2020,14,2: | 5 |
| 10 | High performance hydroxyapatite ceramics and a triply periodic minimum surface structure fabricated by digital light processing 3D printing显示文摘High performance hydroxyapatite(HA)ceramics with excellent densification and mechanical properties were successfully fabricated by digital light processing(DLP)three-dimensional(3D)printing technology.It was found that the sintering atmosphere of wet C02 can dramatically improve the densification process and thus lead to better mechanical properties.HA ceramics with a relative density of 97.12%and a three-point bending strength of 92.4 MPa can be achieved at a sintering temperature of 1300℃,which makes a solid foundation for application in bone engineering.Furthermore,a relatively high compressive strength of 4.09 MPa can be also achieved for a DLP-printed p-cell triply periodic minimum surface(TPMS)structure with a porosity of 74%,which meets the requirement of cancellous bone substitutes.A further cell proliferation test demonstrated that the sintering atmosphere of wet CO2 led to improve cell vitality after 7 days of cell culture Moreover,with the possible benefit from the bio-inspired structure,the 3D-printed TPMS structure significantly improved the cell vitality,which is crucial for early osteogenesis and osteointegration. | Yongxia YAO Wei QIN Bohang XING Na SHA Ting JIAO Zhe ZHAO | 2021 | Journal of Advanced Ceramics2021,10,1: | 5 |
| 11 | Scale Issues of Wetland Classification and Mapping Using Remote Sensing Images: A Case of Honghe National Nature Reserve in Sanjiang Plain, Northeast China显示文摘Wetland research has become a hot spot linking multiple disciplines presently. Wetland classification and mapping is the basis for wetland research. It is difficult to generate wetland data sets using traditional methods because of the low accessibility of wetlands, hence remote sensing data have become one of the primary data sources in wetland research. This paper presents a case study conducted at the core area of Honghe National Nature Reserve in the Sanjiang Plain, Northeast China. In this study, three images generated by airship, from Thematic Mapper and from SPOT 5 were selected to produce wetland maps at three different wetland landscape levels. After assessing classification accuracies of the three maps, we compared the different wetland mapping results of 11 plant communities to the airship image, 6 plant ecotypes to the TM image and 9 landscape classifications to the SPOT 5 image. We discussed the different characteristics of the hierarchical ecosystem classifications based on the spatial scales of the different images. The results indicate that spatial scales of remote sensing data have an important link to the hierarchies of wetland plant ecosystems displayed on the wetland landscape maps. The richness of wetland landscape information derived from an image closely relates to its spatial resolution. This study can enrich the ecological classification methods and mapping techniques dealing with the spatial scales of different remote sensing images. With a better understanding of classification accuracies in mapping wetlands by using different scales of remote sensing data, we can make an appropriate approach for dealing with the scale issue of remote sensing images. | GONG Huili | 2011 | Chinese Geographical Science2011,21,2: | 5 |

| 14 | Occupational exposure to heavy metals, alcohol intake, and risk of type 2 diabetes and prediabetes among Chinese male workers显示文摘Objective: Both exposure to heavy metals and alcohol intake have been related to the risk of type 2 diabetes (T2D). In this study, we aimed to assess the potential interactions between metal exposure and alcohol intake on the risk of T2D and prediabetes in a cohort of Chinese male workers. Methods: We conducted a cross-sectional analysis of 26,008 Chinese male workers in an occupational cohort study from 2011 to 2013. We assessed metal exposure and alcohol consumption at baseline in these workers who were aged ≥20 years. Based on occupations which were categorized according to measured urine metal levels, multiple logistic regression analyses were used to evaluate the independent and joint effects of metal and alcohol exposure on the risk of T2D and prediabetes. Results: Risks of T2D (Ptrend= 0.0 0 1 ) and prediabetes (Ptrend = 0.001) were significantly elevated with increasing number of standard drinks per week, years of drinking, and lifetime alcohol consumption. An adjusted odds ratio (OR) of 6.1 (95% confidence interval [CI]: 4.8-7.8) was observed for the smelting/refining workers (highest metal exposure levels) who had the highest lifetime alcohol consumption (>873 kg)(Pinteraction = 0.018), whereas no statistically significant joint effect was found for prediabetes (Pinteraction =0.515). Conclusions: Both exposures to metal and heavy alcohol intake were associated with the risk of diabetes in this large cohort of male workers. There was a strong interaction between these two exposures in affecting diabetes risk that needs to be confirmed in future studies. | Ai-Min Yang Xiao-Bin Hu Simin Liu Ning Cheng De-Sheng Zhang Juan-Sheng Li Hai-Yan Li Xiao-Wei Ren Na Li Xi-Pin Sheng Jiao Ding Shan Zheng Min-Zheng Wang Tong-Zhang Zheng Ya-Na Bai | 2019 | Chronic Diseases and Translational Medicine2019,5,2: | 4 |
| 15 | On the Mechanism of a Terrain-Influenced Snow Burst Event during Midwinter in Northeast China显示文摘Short-duration snow bursts with heavy snow represent one type of hazardous weather in winter which can be easily missed by the winter weather warnings but often results in great hazards.In this paper,the mechanism for the occurrence of such events was investigated with the aid of a localized terrain-influenced snow burst event in Northeast China.The snow burst was produced by an eastward-moving cold-frontal snowband which encountered the downstream complex terrain of the Changbai Mountains and intensified.To ascertain the role of orography on the snow burst,numerical experiments,together with a parallel sensitivity experiment removing Changbai Mountains,were performed to attempt to distinguish the contributions of cold-frontal system and orographic effects to produce the heavy snow.Diagnosis showed that without the influence of Changbai Mountains,the release of conditional instability(CI)and inertial instability(II)within a weak frontogenetical environment was responsible for the snowband maintenance.Orographic effects played important roles in enhancing the snowband and increasing the snowfall intensities.The enhancement mechanism was related to the interactions of the cold-frontal snowband and the topography.On the one hand,orographic frontogenesis and persistent ascent,created by orographic gravity waves over the terrain,greatly enhanced the orographic lifting.The intensification of the lifting promoted the release of CI and thus enhanced the snowfall.On the other hand,pre-existing orographic instabilities were released due to the passing of the cold-frontal snowband,which could also serve to intensify the snowband over terrain and thus increase the snowfall. | Na LI Baofeng JIAO Lingkun RAN Xinyong SHEN Yanbin QI | 2021 | Advances in Atmospheric Sciences2021,38,5: | 4 |
| 16 | Therapeutic potential of dental pulp stem cell transplantation in a rat model of Alzheimer’s disease显示文摘Dental pulp stem cells are dental pulp-derived mesenchymal stem cells that originate from the neural crest.They exhibit greater potential for the treatment of nervous system diseases than other types of stem cells because of their neurogenic differentiation capability and their ability to secrete multiple neurotrophic factors.Few studies have reported Alzheimer’s disease treatment using dental pulp stem cells.Rat models of Alzheimer’s disease were established by injecting amyloid-β1–42 into the hippocampus.Fourteen days later,5×106 dental pulp stem cells were injected into the hippocampus.Immunohistochemistry and western blot assays showed that dental pulp stem cell transplantation increased the expression of neuron-related doublecortin,NeuN,and neurofilament 200 in the hippocampus,while the expression of amyloid-βwas decreased.Moreover,cognitive and behavioral abilities were improved.These findings indicate that dental pulp stem cell transplantation in rats can improve cognitive function by regulating the secretion of neuron-related proteins,which indicates a potential therapeutic effect for Alzheimer’s disease.This study was approved by the Animal Ethics Committee of Harbin Medical University,China(approval No.KY2017-132)on February 21,2017. | Xue-Mei Zhang Yuan-Jiao Ouyang Bing-Qian Yu Wei Li Mei-Yu Yu Jin-Yue Li Zhuo-Min Jiao Dan Yang Na Li Ying Shi Yun-Yun Xu Zhi-Jun He Duo Wang Hui Yue Jin Fu | 2021 | Neural Regeneration Research2021,16,5: | 3 |

| 18 | Rapid operando gas monitor for commercial lithium ion batteries: Gas evolution and relation with electrode materials显示文摘Internal gases caused by side reactions are crucial signals for evaluating health and safety states of Li-ion batteries(LIBs)while it is still a great challenge to timely realize accurate monitoring.To address the issues of implanting various gas sensors into commercial batteries,here a novel method is developed to fast operando monitoring gas evolution via equipping non-dispersive infrared multi-gases sensors into a sealed tank,where real commercial batteries with one open end could be settled for operating.The generated CO_(2)concentration is strongly linked with both voltage and temperature,while the concentrations of CH_(4) and C_(2)H_(4) are solely dependent on temperature.As a typical trace gas,evolution behaviors of CO_(2)have been related to 0_(2) generation from LiNi_(o.5)Mn_(0.3)CoO_(2)0_(2) positive electrode,implying stable CO_(2)release below a critical voltage of 4.5 V.By tracking CO_(2)concentration,an increased amount of Li_(2)CO_(3) was monitored on the surface of graphite negative electrode during discharge process at dfferent temperatures and cutoff voltages,which contributes to the component variation of solid electrolyte interfaces.Such operando techniques promise a plaform for well understanding the interaction of side reactions linked with gas evolution between positive and negative electrodes in commercial LIBs. | Siqi Lyu Na Li Lei Sun Shuqiang Jiao Haosen Chen Wei-Li Song | 2022 | Journal of Energy Chemistry2022,31,9: | 3 |
| 19 | Plant multiscale networks:charting plant connectivity by multi-level analysis and imaging techniques显示文摘In multicellular and even single-celled organisms,individual components are interconnected at multiscale levels to produce enormously complex biological networks that help these systems maintain homeostasis for development and environmental adaptation.Systems biology studies initially adopted network analysis to explore how relationships between individual components give rise to complex biological processes.Network analysis has been applied to dissect the complex connectivity of mammalian brains across different scales in time and space in The Human Brain Project.In plant science,network analysis has similarly been applied to study the connectivity of plant components at the molecular,subcellular,cellular,organic,and organism levels.Analysis of these multiscale networks contributes to our understanding of how genotype determines phenotype.In this review,we summarized the theoretical framework of plant multiscale networks and introduced studies investigating plant networks by various experimental and computational modalities.We next discussed the currently available analytic methodologies and multi-level imaging techniques used to map multiscale networks in plants.Finally,we highlighted some of the technical challenges and key questions remaining to be addressed in this emerging field. | Xi Zhang Yi Man Xiaohong Zhuang Jinbo Shen Yi Zhang Yaning Cui Meng Yu Jingjing Xing Guangchao Wang Na Lian Zijian Hu Lingyu Ma Weiwei Shen Shunyao Yang Huimin Xu Jiahui Bian Yanping Jing Xiaojuan Li Ruili Li Tonglin Mao Yuling Jiao Sodmergen Haiyun Ren Jinxing Lin | 2021 | Science China(Life Sciences)2021,64,9: | 3 |
| 20 | HMGB1 from Astrocytes Promotes EAE by Influencing the Immune Cell Infiltration-Associated Functions of BMECs in Mice显示文摘High mobility group box 1(HMGB1)has been reported to play an important role in experimental autoimmune encephalomyelitis(EAE).Astrocytes are important components of neurovascular units and tightly appose the endothelial cells of microvessels by their perivascular endfeet and directly regulate the functions of the blood-brain barrier.Astrocytes express more HMGB1 during EAE while the exact roles of astrocytic HMGB1 in EAE have not been well elucidated.Here,using conditional-knockout mice,we found that astrocytic HMGB1 depletion decreased morbidity,delayed the onset time,and reduced the disease score and demyelination of EAE.Meanwhile,there were fewer immune cells,especially pathogenic T cells infiltration in the central nervous system of astrocytic HMGB1 conditional-knockout EAE mice,accompanied by up-regulated expression of the tight-junction protein Claudin5 and down-regulated expression of the cell adhesion molecules ICAM1 and VCAM1 in vivo.In vitro,HMGB1 released from astrocytes decreased Claudin5 while increased ICAM1 and VCAM1 expressed by brain microvascular endothelial cells(BMECs)through TLR4 or RAGE.Taken together,our results demonstrate that HMGB1 derived from astrocytes aggravates EAE by directly influencing the immune cell infiltration-associated functions of BMECs. | Junyu Shi Yifan Xiao Na Zhang Mengya Jiao Xuhuan Tang Chan Dai Chenchen Wang Yong Xu Zheng Tan Feili Gong Fang Zheng | 2022 | Neuroscience Bulletin2022,38,11: | 3 |
