| 1 | Remdesivir and chloroquine effectively inhibit the recently emerged novel coronavirus (2019-nCoV) in vitro显示文摘Dear Editor,In December 2019,a novel pneumonia caused by a previously unknown pathogen emerged in Wuhan,a city of 11 million people in central China.The initial cases were linked to exposures in a seafood market in Wuhan.1 As of January 27,2020,the Chinese authorities reported 2835 confirmed cases in China's Mainland,including 81 deaths.Additionally,19 confirmed cases were identified in Hong Kong,Macao and Taiwan,and 39 imported cases were identified in Thailand,Japan,South Korea,United States,Vietnam,Singapore,Nepal,France,Australia and Canada.The pathogen was soon identified as a novel coronavirus(2019-nCoV),which is closely related to sever acute respiratory syndrome CoV(SARS-CoV).2 Currently,there is no specific treatment against the new virus.Therefore,identifying effective antiviral agents to combat the disease is urgently needed. | Manli Wang Ruiyuan Cao Leike Zhang Xinglou Yang Jia Liu Mingyue Xu Zhengli Shi Zhihong Hu Wu Zhong Gengfu Xiao | 2020 | Cell Research2020，30，3： | 563 |
| 2 | Sequential fate-switches in stem-like cells drive the tumorigenic trajectory from human neural stem cells to malignant glioma显示文摘Glioblastoma(GBM)is an incurable and highly heterogeneous brain tumor,originating from human neural stem/progenitor cells(hNSCs/hNPCs)years ahead of diagnosis.Despite extensive efforts to characterize hNSCs and end-stage GBM at bulk and single-cell levels,the de novo gliomagenic path from hNSCs is largely unknown due to technical difficulties in early-stage sampling and preclinical modeling.Here,we established two highly penetrant hNSC-derived malignant glioma models,which resemble the histopathology and transcriptional heterogeneity of human GBM.Integrating time-series analyses of whole-exome sequencing,bulk and single-cell RNA-seq,we reconstructed gliomagenic trajectories,and identified a persistent NSC-like population at all stages of tumorigenesis.Through trajectory analyses and lineage tracing,we showed that tumor progression is primarily driven by multi-step transcriptional reprogramming and fate-switches in the NSC-like cells,which sequentially generate malignant heterogeneity and induce tumor phenotype transitions.We further uncovered stage-specific oncogenic cascades,and among the candidate genes we functionally validated C1QL1 as a new glioma-promoting factor.Importantly,the neurogenic-to-gliogenic switch in NSC-like cells marks an early stage characterized by a burst of oncogenic alterations,during which transient AP-1 inhibition is sufficient to inhibit gliomagenesis.Together,our results reveal previously undercharacterized molecular dynamics and fate choices driving de novo gliomagenesis from hNSCs,and provide a blueprint for potential early-stage treatment/diagnosis for GBM. | Xiaofei Wang Ran Zhou Yanzhen Xiong Lingling Zhou Xiang Yan Manli Wang Fan Li Chuanxing Xie Yiming Zhang Zongyao Huang Chaoqiong Ding Kaidou Shi Weida Li Yu Liu Zhongwei Cao Zhen-Ning Zhang Shengtao Zhou Chong Chen Yan Zhang Lu Chen Yuan Wang | 2021 | Cell Research2021，31，6： | 8 |
| 3 | Identification of Porphyra lines using computerized DNA fingerprinting显示文摘RAPD (Randomly Amplified Polymorphic DNA) analysis was performed with filaments of 15 Porphyra lines representing four important groups (P. yezoensis, P. haitanensis, P. katadai var. Hemiphylla and P. digospermatangia). Eight stable and repeatable RAPD bands amplified with two primers, OPN-02 and OPJ-18, were selected for the construction of DNA fingerprinting. The RAPD results were scored based on the presence or absence of each of the 8 bands and then converted to computer language expressed with two digitals, 1 and 0, which represented the presence (numbered as 1) or absence (numbered as 0) of each band, respectively. Based on these results, a model DNA fingerprint and a computerized DNA fingerprint were constructed. In the constructed DNA fingerprint, each Porphyra line has its unique fingerprinting pattern and can be easily distinguished from each other. Later, a software, named as PhGI, was designed based on this DNA fingerprinting. It can be used in practical Porphyra line identification. | WangBin, Jia Jianhang, Shi Jinfeng, Chen Yihua, JinDemin, Xu Pu, Mei Junxue, Weng Manli 1.

| 4 | Rapid isolation and immune profiling of SARS-CoV-2 specific memory B cell in convalescent COVID-19 patients via LIBRA-seq显示文摘B cell response plays a critical role against SARS-CoV-2 infection.However,little is known about the diversity and frequency of the paired SARS-CoV-2 antigen-specific BCR repertoire after SARS-CoV-2 infection.Here,we performed single-cell RNA sequencing and VDJ sequencing using the memory and plasma B cells isolated from five convalescent COVID-19 patients,and analyzed the spectrum and transcriptional heterogeneity of antibody immune responses.Via linking BCR to antigen specificity through sequencing(LIBRA-seq),we identified a distinct activated memory B cell subgroup(CD11c^(high) CD95^(high))had a higher proportion of SARS-CoV-2 antigen-labeled cells compared with memory B cells.Our results revealed the diversity of paired BCR repertoire and the non-stochastic pairing of SARS-CoV-2 antigen-specific immunoglobulin heavy and light chains after SARS-CoV-2 infection.The public antibody clonotypes were shared by distinct convalescent individuals.Moreover,several antibodies isolated by LIBRA-seq showed high binding affinity against SARS-CoV-2 receptor-binding domain(RBD)or nucleoprotein(NP)via ELISA assay.Two RBD-reactive antibodies C14646P3S and C2767P3S isolated by LIBRA-seq exhibited high neutralizing activities against both pseudotyped and authentic SARS-CoV-2 viruses in vitro.Our study provides fundamental insights into B cell response following SARS-CoV-2 infection at the single-cell level. | Bing He Shuning Liu Yuanyuan Wang Mengxin Xu Wei Cai Jia Liu Wendi Bai Shupei Ye Yong Ma Hengrui Hu Huicui Meng Tao Sun Yanling Li Huanle Luo Mang Shi Xiangjun Du Wenjing Zhao Shoudeng Chen Jingyi Yang Haipeng Zhu Yusheng Jie Yuedong Yang Deyin Guo Qiao Wang Yuwen Liu Huimin Yan Manli Wang Yao-Qing Chen | 2021 | Signal Transduction and Targeted Therapy2021，6，6： | 2 |
| 5 | Design and Implementation of Dynamic High-Speed Switches in Super Base Station Architectures显示文摘Novel centralized base station architectures integrating computation and communication functionalities have become important for the development of future mobile communication networks.Therefore,the development of dynamic high-speed interconnections between baseband units(BBUs)and remote radio heads(RRHs)is vital in centralized base station design.Herein,dynamic high-speed switches(HSSs)connecting BBUs and RRHs were designed for a centralized base station architecture.We analyzed the characteristics of actual traffic and introduced a switch traffic model suitable for the super base station architecture.Then,we proposed a data-priority-aware(DPA)scheduling algorithm based on the traffic model.Lastly,we developed the dynamic HSS model based on the OPNET platform and the prototype based on FPGA.Our results show that the DPA achieves close to 100%throughput with lower latency and provides better run-time complexity than iOCF and HE-iSLIP,thereby demonstrating that the proposed switch system can be adopted in centralized base station architectures. | Yingjiao Ma Jinglin Shi Yiqing Zhou Lin Tian Manli Qian | 2020 | China Communications2020，17，3： | 1 |

| 7 | Hybridoma-derived neutralizing monoclonal antibodies against Beta and Delta variants of SARS-CoV-2 in vivo显示文摘Neutralizing monoclonal antibodies(mAb)are a major therapeutic strategy for the treatment of severe acute respiratory syndrome coronavirus-2(SARS-CoV-2)infection.The continuous emergence of new SARS-CoV-2 variants worldwide has increased the urgency for the development of new mAbs.In this study,we immunized mice with the receptor-binding domain(RBD)of the SARS-CoV-2 prototypic strain(WIV04)and screened 35 RBDspecific mAbs using hybridoma technology.Results of the plaque reduction neutralization test showed that 25 of the mAbs neutralized authentic WIV04 strain infection.The 25 mAbs were divided into three categories based on the competitive enzyme-linked immunosorbent assay results.A representative mAb was selected from each category(RD4,RD10,and RD14)to determine the binding kinetics and median inhibitory concentration(IC_(50))of WIV04 and two variants of concern(VOC):B.1.351(Beta)and B.1.617.2(Delta).RD4 neutralized the B.1.617.2 variant with an IC50 of 2.67 ng/mL;however,it completely lost neutralizing activity against the B.1.351 variant.RD10 neutralized both variants with an IC50 exceeding 100 ng/mL;whereas RD14 neutralized two variants with a higher IC50(>1 mg/mL).Animal experiments were performed to evaluate the protective effects of RD4 and RD10 against various VOC infections.RD4 could protect Adv-hACE2 transduced mice from B.1.617.2 infection at an antibody concentration of 25 mg/kg,while RD10 could protect mice from B.1.351 infection at an antibody concentration of 75 mg/kg.These results highlight the potential for future modifications of the mAbs for practical use. | Qianran Wang Lu Peng Yanqiu Nie Yanni Shu Huajun Zhang Zidan Song Yufeng Li Hengrui Hu Liushuai Li Xi Wang Jia Liu Jiang Li Zhengli Shi Fei Deng Yu Guo Yiwu Zhou Bing Yan Zhihong Hu Manli Wang | 2023 | Virologica Sinica2023，38，2： | 0 |

| 9 | Comparative Antiviral Efficacy of Viral Protease Inhibitors against the Novel SARS-CoV-2 In Vitro显示文摘The recent outbreak of novel coronavirus pneumonia(COVID-19)caused by a new coronavirus has posed a great threat to public health.Identifying safe and effective antivirals is of urgent demand to cure the huge number of patients.Virusencoded proteases are considered potential drug targets.The human immunodeficiency virus protease inhibitors(lopinavir/ritonavir)has been recommended in the global Solidarity Trial in March launched by World Health Organization.However,there is currently no experimental evidence to support or against its clinical use.We evaluated the antiviral efficacy of lopinavir/ritonavir along with other two viral protease inhibitors in vitro,and discussed the possible inhibitory mechanism in silico.The in vitro to in vivo extrapolation was carried out to assess whether lopinavir/ritonavir could be effective in clinical.Among the four tested compounds,lopinavir showed the best inhibitory effect against the novel coronavirus infection.However,further in vitro to in vivo extrapolation of pharmacokinetics suggested that lopinavir/ritonavir could not reach effective concentration under standard dosing regimen[marketed as Kaletraò,contained lopinavir/ritonavir(200 mg/50 mg)tablets,recommended dosage is 400 mg/10 mg(2 tablets)twice daily].This research concluded that lopinavir/ritonavir should be stopped for clinical use due to the huge gap between in vitro IC50 and free plasma concentration.Nevertheless,the structure–activity relationship analysis of the four inhibitors provided further information for de novel design of future viral protease inhibitors of SARS-CoV-2. | Leike Zhang Jia Liu Ruiyuan Cao Mingyue Xu Yan Wu Weijuan Shang Xi Wang Huanyu Zhang Xiaming Jiang Yuan Sun Hengrui Hu Yufeng Li Gang Zou Min Zhang Lei Zhao Wei Li Xiaojia Guo Xiaomei Zhuang Xing-Lou Yang Zheng-Li Shi Fei Deng Zhihong Hu Gengfu Xiao Manli Wang Wu Zhong | 2020 | Virologica Sinica2020，35，6： | 0 |
