1Comparison of nonhuman primates identified the suitable model for COVID-19显示文摘Identification of a suitable nonhuman primate(NHP)model of COVID-19 remains challenging.Here,we characterized severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection in three NHP species:Old World monkeys Macaca mulatta(M.mulatta)and Macaca fascicularis(M.fascicularis)and New World monkey Callithrix jacchus(C.jacchus).Infected M.mulatta and M.fascicularis showed abnormal chest radiographs,an increased body temperature and a decreased body weight.Viral genomes were detected in swab and blood samples from all animals.Viral load was detected in the pulmonary tissues of M.mulatta and M.fascicularis but not C.jacchus.Furthermore,among the three animal species,M.mulatta showed the strongest response to SARS-CoV-2,including increased inflammatory cytokine expression and pathological changes in the pulmonary tissues.Collectively,these data revealed the different susceptibilities of Old World and New World monkeys to SARS-CoV-2 and identified M.mulatta as the most suitable for modeling COVID-19.Shuaiyao Lu Yuan Zhao Wenhai Yu Yun Yang Jiahong Gao Junbin Wang Dexuan Kuang Mengli Yang Jing Yang Chunxia Ma Jingwen Xu Xingli Qian Haiyan Li Siwen Zhao Jingmei Li Haixuan Wang Haiting Long Jingxian Zhou Fangyu Luo Kaiyun Ding Daoju Wu Yong Zhang Yinliang Dong Yuqin Liu Yinqiu Zheng Xiaochen Lin Li Jiao Huanying Zheng Qing Dai Qiangming Sun Yunzhang Hu Changwen Ke Hongqi Liu Xiaozhong Peng 2020Signal Transduction and Targeted Therapy2020,5,1:5
2Histones released by NETosis enhance the infectivity of SARS-CoV-2 by bridging the spike protein subunit 2 and sialic acid on host cells显示文摘Neutrophil extracellular traps(NETs)can capture and kill viruses,such as influenza viruses,human immunodeficiency virus(HIV),and respiratory syncytial virus(RSV),thus contributing to host defense.Contrary to our expectation,we show here that the histones released by NETosis enhance the infectivity of SARS-CoV-2,as found by using live SARS-CoV-2 and two pseudovirus systems as well as a mouse model.The histone H3 or H4 selectively binds to subunit 2 of the spike(S)protein,as shown by a biochemical binding assay,surface plasmon resonance and binding energy calculation as well as the construction of a mutant S protein by replacing four acidic amino acids.Sialic acid on the host cell surface is the key molecule to which histones bridge subunit 2 of the S protein.Moreover,histones enhance cell-cell fusion.Finally,treatment with an inhibitor of NETosis,histone H3 or H4,or sialic acid notably affected the levels of sgRNA copies and the number of apoptotic cells in a mouse model.These findings suggest that SARS-CoV-2 could hijack histones from neutrophil NETosis to promote its host cell attachment and entry process and may be important in exploring pathogenesis and possible strategies to develop new effective therapies for COVID-19.Weiqi Hong Jingyun Yang Jun Zou Zhenfei Bi Cai He Hong Lei Xuemei He Xue Li Aqu Alu Wenyan Ren Zeng Wang Xiaohua Jiang Kunhong Zhong Guowen Jia Yun Yang Wenhai Yu Qing Huang Mengli Yang Yanan Zhou Yuan Zhao Dexuan Kuang Junbin Wang Haixuan Wang Siyuan Chen Min Luo Ziqi Zhang Tiangi Lu Li Chen Haiying Que Zhiyao He Qiu Sun Wei Wang Guobo Shen Guangwen Lu Zhiwei Zhao Li Yang Jinliang Yang Zhenling Wang Jiong Li Xiangrong Song Lunzhi Dai Chong Chen Jia Geng Maling Gou Lu Chen Haohao Dong Yong Peng Canhua Huang Zhiyong Qian Wei Cheng Changfa Fan Yuquan Wei Zhaoming Su Aiping Tong Shuaiyao Lu Xiaozhong Peng Xiawei Wei 2022Cellular & Molecular Immunology2022,19,5:2
3A chromosome-scale genome assembly of Dasypyrum villosum provides insights into its application as a broad-spectrum disease resistance resource for wheat improvement显示文摘Dasypyrum villosum is one of the most valuable gene resources in wheat improvement,especially for disease resistance.The mining of favorable genes from D.villosum is frustrated by the lack of a whole genome sequence.In this study,we generated a doubled-haploid line,91C43^(DH),using microspore culture and obtained a 4.05-GB high-quality,chromosome-scale genome assembly for D.villosum.The assembly contains39727 high-confidence genes,and 85.31% of the sequences are repetitive.Two reciprocal translocation events were detected,and 7VS-4VL is a unique translocation in D.villosum.The prolamin seed storage protein-coding genes were found to be duplicated;in particular,the genes encoding low-molecular-weight glutenin at the Glu-V3 locus were significantly expanded.RNA sequencing(RNA-seq)analysis indicated that,after Blumeria graminearum f.sp tritici(Bgt)inoculation,there were more upregulated genes involved in the pattern-triggered immunity and effector-triggered immunity defense pathways in D.villosum than in Triticum urartu.MNase hypersensitive sequencing(MH-seq)identified two Bgt-inducible MH sites(MHSs),one in the promoter and one in the 3'terminal region of the powdery mildew resistance(Pm)gene NLR1-V.Each site had two subpeaks and they were termed MHS1(MHS1.1/1.2)and MHS2(MHS2.1/2.2).Bgt-inducible MHS2.2 was uniquely present in D.villosum,and MHS1.1 was more inducible in D.villosum than in wheat,suggesting that MHSs may be critical for regulation of NLR1-V expression and plant defense.In summary,this study provides a valuable genome resource for functional genomics studies and wheat-D.villosum introgression breeding.The identified regulatory mechanisms may also be exploited to develop new strategies for enhancing Pm resistance by optimizing gene expression in wheat.Xu Zhang Haiyan Wang Haojie Sun Yingbo Li Yilong Feng Chengzhi Jiao Mengli Li Xinying Song Tong Wang Zongkuan Wang Chunxia Yuan Li Sun Ruju Lu Wenli Zhang Jin Xiao Xiue Wang 2023Molecular Plant2023,16,2:1
4Preparation of Gallic Acid-chitosan Copolymer and Its Antibacterial Activity against Staphylococcus Aureus and Escherichia Coli显示文摘To synthesize three different grafting ratios of gallic acid(GA)-chitosan(CS)copolymer by a free radical mediated grafting method,which is further applied to the field of antibacterial materials,crosslinking structures of the compound GA-CS copolymer were characterized,fully indicating that gallic acid is resoundingly grafted onto chitosan.The grafting ratios of three copolymers GA-CS are 45.71%(Ⅰ),36.12%(Ⅱ),and 18.96%(Ⅲ)were determined by UV-Vis spectrophotometer.The minimum inhibitory concentrations of three GA-CS copolymers are 30μg/mL against Escherichia coli and are ranged from 250 to 550μg/mL against Staphylococcus aureus.By counting viable bacterial colonies,it can be found that antibacterial property is preferable by increasing the grafting ratio of GA-CS copolymers.Findings of investigation on aforementioned bacteria experiment indicate that the CFU/mL values of GA-CS(Ⅰ,Ⅱ,Ⅲ)are 2.04×10^(6),7.56×10^(6),1.48×10^(7) to Staphylococcus aureus,and 2.96×10^(6),1.01×10^(7),2.14×10^(7) to Escherichia coli after 12 h treatment.In addition,the interaction process between GA-CS copolymer and bacteria can be observed through a transmission electron microscope.The specific manifestation is that the bacterial cell membranes are ruptured after being treated with the copolymer,which causes the cell contents to flow out,and the cell morphology is shrunk and out ofshape.颜春潮 肖锋 QIU Tong ZHANG Xueqiong ZHAN Siwen LU Mengli 杨梦佳 张娟 2021Journal of Wuhan University of Technology(Materials Science)2021,36,6:1

6Clinical characteristics and vaccine effectiveness against SARS-CoV-2 Omicron subvariant BA.2 in the children显示文摘Dear Editor,The Omicron variant of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)has rapidly replaced the Delta variant as a dominating SARS-CoV-2 variant because of natural selection,which favors the variant with higher infectivity and stronger vaccine breakthrough ability.1 Among three lineages BA.1(B.1.1.529.1),BA.2(B.1.1.529.2),and BA.3(B.1.1.529.3)of Omicron,BA.2 is rising rapidly worldwide since January 2022 and become a new dominating“variant of concern”in China.2 With the current surge in Omicron in China,both the absolute number of children hospitalized with COVID-19 and the percentage of total COVID-19 hospitalizations have been boosting recently.Understanding the clinical characteristics of SARS-CoV-2 Omicron subvariant BA.2 in children and the protective effect of vaccines is of great help for epidemic prevention strategies.However,so far no sufficient experimental data have been reported about infectivity,disease severity,vaccine breakthrough capability,and antibody resistance from pediatric BA.2.Xiaohe Li Liwen Wu Youzhi Qu Mengli Cao Jiaqi Feng Hua Huang Yi Liu Hongzhou Lu Quanying Liu Yingxia Liu 2022Signal Transduction and Targeted Therapy2022,7,7:0
7The olfactory route is a potential way for SARS-CoV-2 to invade the central nervous system of rhesus monkeys显示文摘Neurological manifestations are frequently reported in the COVID-19 patients.Neuromechanism of SARS-CoV-2 remains to be elucidated.In this study,we explored the mechanisms of SARS-CoV-2 neurotropism via our established non-human primate model of COVID-19.In rhesus monkey,SARS-CoV-2 invades the CNS primarily via the olfactory bulb.Thereafter,viruses rapidly spread to functional areas of the central nervous system,such as hippocampus,thalamus,and medulla oblongata.The infection of SARS-CoV-2 induces the inflammation possibly by targeting neurons,microglia,and astrocytes in the CNS.Consistently,SARS-CoV-2 infects neuro-derived SK-N-SH,glial-derived U251,and brain microvascular endothelial cells in vitro.To our knowledge,this is the first experimental evidence of SARS-CoV-2 neuroinvasion in the NHP model,which provides important insights into the CNS-related pathogenesis of SARS-CoV-2.Li Jiao Yun Yang Wenhai Yu Yuan Zhao Haiting Long Jiahong Gao Kaiyun Ding Chunxia Ma Jingmei Li Siwen Zhao Haixuan Wang Haiyan Li Mengli Yang Jingwen Xu Junbin Wang Jing Yang Dexuan Kuang Fangyu Luo Xingli Qian Longjiang Xu Bin Yin Wei Liu Hongqi Liu Shuaiyao Lu Xiaozhong Peng 2021Signal Transduction and Targeted Therapy2021,6,5:0
