| 1 | Age-related rhesus macaque models of COVID-19显示文摘Background:Since December 2019,an outbreak of the Corona Virus disease 2019(COVID-19)caused by severe acute respiratory syndrome coronavirus(SARS-CoV-2)in Wuhan,China,has become a public health emergency of international concern.The high fatality of aged cases caused by SARS-CoV-2 was a need to explore the possible age-related phenomena with non-human primate models.Methods:Three 3-5 years old and two 15 years old rhesus macaques were intratracheally infected with SARS-CoV-2,and then analyzed by clinical signs,viral replication,chest X-ray,histopathological changes and immune response.Results:Viral replication of nasopharyngeal swabs,anal swabs and lung in old monkeys was more active than that in young monkeys for 14 days after SARS-CoV-2 challenge.Monkeys developed typical interstitial pneumonia characterized by thickened alveolar septum accompanied with inflammation and edema,notably,old monkeys exhibited diffuse severe interstitial pneumonia.Viral antigens were detected mainly in alveolar epithelial cells and macrophages.Conclusion:SARS-CoV-2 caused more severe interstitial pneumonia in old monkeys than that in young monkeys.Rhesus macaque models infected with SARS-CoV-2 provided insight into the pathogenic mechanism and facilitated the development of vaccines and therapeutics against SARS-CoV-2 infection. | Pin Yu Feifei Qi Yanfeng Xu Fengdi Li Peipei Liu Jiayi Liu Linlin Bao Wei Deng Hong Gao Zhiguang Xiang Chong Xiao Qi Lv Shuran Gong Jiangning Liu Zhiqi Song Yajin Qu Jing Xue Qiang Wei Mingya Liu Guanpeng Wang Shunyi Wang Haisheng Yu Xing Liu Baoying Huang Wenling Wang Li Zhao Huijuan Wang Fei Ye Weimin Zhou Wei Zhen Jun Han Guizhen Wu Qi Jin Jianwei Wang Wenjie Tan Chuan Qin | 2020 | Animal Models and Experimental Medicine2020,3,1: | 22 |
| 2 | Detection of DNA methylation changes during seed germination in rapeseed (Brassica napus)显示文摘DNA methylation is known to play a crucial role in regulating plant development and or- gan or tissue differentiation. In this study, we as- sessed the extent and pattern of cytosine methylation during rapeseed (Brassica napus L.) seed germina- tion, and compared the methylation level of various tissues in seedling, using the techniques of methyla- tion-sensitive amplified polymorphism (MSAP) and HPLC separation and quantification of nucleosides. In all, 484 bands, each representing a recognition site cleaved by either or both of the isoschizomers, were amplified by 12 pairs of selective primers in DNA ob- tained from dry seeds. A total of 76 sites were found to be differentially digested by the isoschizomers, indicating that approximately 15.7% of 5′-CCGG-3′ sites in the genome were cytosine methylated. Four classes of patterns were observed in a comparative assay of cytosine methylation in the dry and germi- nating seeds; a small number of hypermethylation events occurred at 5′-CCGG-3′ sites in germinating seeds compared with dry seeds, while many more hypomethylation events were detected after seed germination. Differences in DNA methylation level in various tissues were also detected; radicel was less methylated than hypocotyl and cotyledon. These observations were further confirmed by HPLC analy- sis. In addition, sequencing of eleven differentially methylated fragments and the subsequent blast search revealed that cytosine methylated 5′-CCGG- 3′ sequences were equally distributed between cod- ing and non-coding regions. These results clearly demonstrate the power of MSAP technique for large-scale DNA methylation detection in rapeseed genome, and the complexity of DNA methylationchange during seed germination. DNA Hypomethyla- tion going with seed germination appears to be a necessary step toward transcriptional activation in gene expression, and may well contribute to the de- velopmental gene regulation. | LU Guangyuan WU Xiaoming CHEN Biyun GAO Guizhen XU Kun LI Xiangzhi | 2006 | Chinese Science Bulletin2006,51,2: | 14 |
| 3 | Hes1 Knockdown Exacerbates Ischemic Stroke Following tMCAO by Increasing ER Stress-Dependent Apoptosis via the PERK/ eIF2a/ATF4/CHOP Signaling Pathway显示文摘Apoptosis induced by endoplasmic reticulum(ER)stress plays a crucial role in mediating brain damage after ischemic stroke.Recently,Hes1(hairy and enhancer of split 1)has been implicated in the regulation of ER stress,but whether it plays a functional role after ischemic stroke and the underlying mechanism remain unclear.In this study,using a mouse model of ischemic stroke via transient middle cerebral artery occlusion(tMCAO),we found that Hes1 was induced following brain injury,and that siRNA-mediated knockdown of Hes1 increased the cerebral infarction and worsened the neurological outcome,suggesting that Hes1 knockdown exacerbates ischemic stroke.In addition,mechanistically,Hes1 knockdown promoted apoptosis and activated the PERK/eIF2a/ATF4/CHOP signaling pathway after tMCAO.These results suggest that Hes1 knockdown promotes ER stress-induced apoptosis.Furthermore,inhibition of PERK with the specific inhibitor GSK2606414 markedly attenuated the Hes1 knockdown-induced apoptosis and the increased cerebral infarction as well as the worsened neurological outcome following tMCAO,implying that the protection of Hes1 against ischemic stroke is associated with the amelioration of ER stress via modulating the PERK/eIF2a/ATF4/CHOP signaling pathway.Taken together,these results unveil the detrimental role of Hes1 knockdown after ischemic stroke and further relate it to the regulation of ER stress-induced apoptosis,thus highlighting the importance of targeting ER stress in the treatment of ischemic stroke. | Yueyong Li Yingjun Zhang Huangde Fu Huadong Huang Qifeng Lu Houji Qin Yingning Wu Huatuo Huang Guizhen Mao Zhongheng Wei Pinhu Liao | 2020 | Neuroscience Bulletin2020,36,2: | 12 |
| 4 | Reemergent Cases of COVID-19—Xinfadi Wholesales Market,Beijing Municipality,China,June 11,2020显示文摘No new local coronavirus disease 2019(COVID-19)cases were reported in Beijing for over 56 days before the reemergent COVID-19 cases that were reported on June 11,2020,and more than 200 confirmed cases have been reported as of June 20 in Beijing.All confirmed COVID-19 cases were associated with Xinfadi Wholesale Market.Here,we reported the phylogenetic characteristics of the COVID-19 viruses(also known as severe acute respiratory syndrome coronavirus 2,SARS-CoV-2,and human coronavirus 2019,HCoV-19)sequenced from the clinical specimens of 2 human cases and 1 environmental sample. | Wenjie Tan Peihua Niu Xiang Zhao Yang Pan Yong Zhang Lijuan Chen Li Zhao Yanhai Wang Dayan Wang Jun Han George FGao Chun Huang Wenbo Xu Guizhen Wu | 2020 | China CDC weekly2020,2,27: | 6 |
| 5 | CD147 antibody specifically and effectively inhibits infection and cytokine storm of SARS-CoV-2 and its variants delta,alpha,beta,and gamma显示文摘SARS-CoV-2 mutations contribute to increased viral transmissibility and immune escape,compromising the effectiveness of existing vaccines and neutralizing antibodies.An in-depth investigation on COVID-19 pathogenesis is urgently needed to develop a strategy against SARS-CoV-2 variants.Here,we identified CD147 as a universal receptor for SARS-CoV-2 and its variants.Meanwhile,Meplazeumab,a humanized anti-CD147 antibody,could block cellular entry of SARS-CoV-2 and its variants-alpha,beta,gamma,and delta,with inhibition rates of 68.7,75.7,52.1,52.1,and 62.3%at 60μg/ml,respectively.Furthermore,humanized CD147 transgenic mice were susceptible to SARS-CoV-2 and its two variants,alpha and beta.When infected,these mice developed exudative alveolar pneumonia,featured by immune responses involving alveoli-infiltrated macrophages,neutrophils,and lymphocytes and activation of IL-17 signaling pathway.Mechanistically,we proposed that severe COVID-19-related cytokine storm is induced by a'spike protein-CD147-CyPA signaling axis':Infection of SARS-CoV-2 through CD147 initiated the JAK-STAT pathway,which further induced expression of cyclophilin A(CyPA);CyPA reciprocally bound to CD147 and triggered MAPK pathway.Consequently,the MAPK pathway regulated the expression of cytokines and chemokines,which promoted the development of cytokine storm.Importantly,Meplazumab could effectively inhibit viral entry and inflammation caused by SARS-CoV-2 and its variants.Therefore,our findings provided a new perspective for severe COVID-19-related pathogenesis.Furthermore,the validated universal receptor for SARS-CoV-2 and its variants can be targeted for COVID-19 treatment. | Jiejie Geng Liang Chen Yufeng Yuan Ke Wang Youchun Wang Chuan Qin Guizhen Wu Ruo Chen Zheng Zhang Ding Wei Peng Du Jun Zhang Peng Lin Kui Zhang Yongqiang Deng Ke Xu Jiangning Liu Xiuxuan Sun Ting Guo Xu Yang Jiao Wu Jianli Jiang Ling Li Kun Zhang Zhe Wang Jing Zhang Qingguo Yan Hua Zhu Zhaohui Zheng Jinlin Miao Xianghui Fu Fengfan Yang Xiaochun Chen Hao Tang Yang Zhang Ying Shi Yumeng Zhu Zhuo Pei Fei Huo Xue Liang Yatao Wang Qingyi Wang Wen Xie Yirong Li Mingyan Shi Huijie Bian Ping Zhu Zhi-Nan Chen | 2021 | Signal Transduction and Targeted Therapy2021,6,10: | 6 |
| 6 | Study of latch-up immunization in bulk CMOS integrated circuits exposed to transient ionizing radiation显示文摘This paper presents experimental results of transient gamma irradiation effects on two kinds of circuits.One is a two-stage circuit consisting of a bipolar power device L7805CV and a bulk complementary metal-oxide-semiconductor(CMOS) device IDT6116,the other is a two-stage circuit consisting of a bipolar power device L7805CV and the equivalent circuit of the parasitic P-N-P-N structure in bulk CMOS devices.The results show that the L7805CV's output interruption after transient irradiation can prevent latch-up from occurring on the second stage circuit.The demanded minimum interruption duration to avoid latch-up varies with dose rate,and this is confirmed by the experimental results. | LI RuiBin CHEN Wei LIN DongSheng YANG ShanChao BAI XiaoYan WANG GuiZhen LIU Yan QI Chao MA Qiang | 2012 | Science China(Technological Sciences)2012,55,11: | 5 |

| 8 | Brain neural effects of the ’tonifying kidney and benefiting marrow’ method in the treatment of osteoporosis显示文摘In Traditional Chinese Medicine(TCM),the'tonifying kidney and benefiting marrow'(TKBM)method is based on the theory that kidney controls bones,while marrow moistens bones.There have been aboundant theoretical studies on kidney controlling bones since Huangdi's Internal Classics.Howev-er,there are too few ones about the marrow moistening the bones.Researchers generally use the tonifying kidney method instead of the TKBM method,which causes lack of a unified standard and theoretical basis in evaluating the TKBM method.Herein,we first proposed the hypothesis that deficiency of marrow sea causes osteoporosis.Next,we prove the scientific validity of this hypothesis from the side of the TCM theory on the relationship among kidney,bone and marrow sea physiologically and pathologically.Based on this,we find that the TCM theory provides theoretical basis for deficiency of marrow sea causing osteoporosis.On the other side,Western Medicine theory holds that(a)physiologically,the brain regulates the bone mass via three pathways:the neuro-osteogenic network,neuro-endocrine-bone network,and neuropeptide-bone network;(b)pathologically,brain impacts bone mass via three major passways including the regulation of the sympathetic nervous system,secreting hormones that directly act on bone cells and regulating the synthesis and secretion of hormones in the intermediary organs,and neuropeptides such as neuropeptide Y(NPY),substance P(SP),and calcitonin gene-related peptide(CGRP).Evidences involving estrogen deficiency,sympatheticotonia,or neuropeptides imbalance prove that brain-bone mass regulation plays an important role in the pathogenesis of osteoporosis.Finally,we find that kidney invigoration method can change the concentrations of central neurotransmitters of norepinephrine and glutamate to regulate neuro-osteogenic network,and promote the recovery of ovarian function and have an estrogen-like effect by regulating the hypothalamus-pituitary-ovarian axis,which thus influences bone metabolism without clinically significant estro-gen-like side effects,and regulate NPY,CGRP and SP involved in the bone metabolism.These further support our hypothesis by revealing the brain neural mechanism of the TCM kidney invigoration method for preventing and treating osteoporosis.In the future,neuroimaging techniques may be useful in exploring its neural effects and also aid in developing new strategies for treating osteoporosis. | Xu Yunxiang Liu Xueqin Li Haolan Liu Hongyuan Pan Zhanxia Chen Guizhen | 2019 | Journal of Traditional Chinese Medicine2019,39,6: | 5 |
| 9 | Use of rare earth elements in single-atom site catalysis:A critical review——Commemorating the 100th anniversary of the birth of Academician Guangxian Xu显示文摘Rare earth metals are strategic resources with potential applications in optics,metallurgy and catalysis.In recent years,single-atom site catalysts(SASCs) have attracted increasing attention owing to their 100%atom efficiency and unique catalytic performances.Over the past decade,rare earth elements,including rare earth metals and their oxides,have shown great potential in SASCs.However,systematic analyses of data are still handful.In this mini-review,the use of rare earth metals and their oxides in SASCs was summarized and the results are discussed.A particular focus was paid to the synthetic strategies,characterization of rare earth-containing SASCs,and applications as catalysis supports,promoters and active sites.Current issues faced by rare-earth metals and their oxides in SASCs,as well as future prospects were also provided. | Ningqiang Zhang Han Yan Lingcong Li Rui Wu Liyun Song Guizhen Zhang Wenjun Liang Hong He | 2021 | Journal of Rare Earths2021,39,3: | 4 |
| 10 | Identification of Histoplasma causing an unexplained disease cluster in Matthews Ridge, Guyana显示文摘Here,we report the identification of Histoplasma causing an unexplained disease cluster in Matthews Ridge,Guyana.In March 2019,14 employees of Chongqing Bosai Mining Company,China,working in a manganese mining of Guyana,had unexplained fever,and two of them died.We obtained lung and brain tissues as well as the blood samples from the two deceased cases(patient No.1 and 2),and bronchoscopy lavages and cerebrospinal fluid samples from one severe case(patient No.3),respectively.All samples were tested by pathological examination,high-throughput sequencing,and real-time PCR.Pathological detection showed the presence of spore-like structures in the lung tissue of patient No.1,indicating a fungal infection in this patient.Nanopore sequencing identified the existing of H.capsulatum in the lung tissue sample within 13 h.Next-generation sequencing identified specific fragments of H.capsulatum in all of the samples tested(lung,brain and blood serum from the deceased cases,and plasma from the severe case).Real-time PCR assays did not reveal any viral infection related to transmission from bat feces.We conclude that H.capsulatum was the causative pathogen of this disease cluster based on epidemiologic,clinical,pathological and nucleic acid evidence. | Ji Wang Weimin Zhou Hua Ling Xiaoping Dong Yi Zhang Jiandong Li Yong Zhang Jingdong Song William J.Liu Yang Li Ruiqing Zhang Wei Zhen Kun Cai Shuangli Zhu Dongyan Wang Jinbo Xiao Yigang Tong Wenli Liu Lihua Song Wei Wu Yang Liu Xiang Zhao Ruihuan Wang Sheng Ye Jing Wang Roujian Lu Baoying Huang Fei Ye Wenwen Lei Rongbao Gao Qi Shi Cao Chen Jun Han Wenbo Xu George F.Gao Xuejun Ma Guizhen Wu | 2019 | Biosafety and Health2019,1,3: | 3 |
| 11 | Isolation and Characterization of Monkeypox Virus from the First Case of Monkeypox—Chongqing Municipality,China,2022显示文摘Introduction:The first imported case of monkeypox(MPX)from the mainland of China was reported in September 2022.Herein,the study reports the isolation and characterization of MPX virus(MPXV)in this case.Methods:Clinical specimens including skin blister fluid,oropharyngeal and nasopharyngeal swabs,and blood were collected and inoculated onto Vero cells.The isolated virus was identified as MPXV using quantitative polymerase chain reaction(qPCR),cytopathic effects(CPEs),immunofluorescence assay(IFA)and transmission electron microscopy(TEM).Plaque assays were employed to quantify infectious plaque-forming units(PFUs).The plaque reduction neutralization test(PRNT)was developed to determine the neutralizing antibody(nAb)against MPXV.Results:MPXV replication was confirmed with qPCR.Typical CPEs were observed 48 h postincubation.The isolated virus was named MPXV-B.1-China-C-Tan-CQ01.IFA showed that MPXV reacted with serum of MPX case.Orthopoxvirus morphology was observed using TEM.The virus titer increased to>106 PFU/mL after three passages.The serum PRNT 50%neutralization titer(NT50)was 35 for the MPX patient 6 days after symptom onset.Discussion:The study successfully isolated the first MPXV strain in the mainland of China,MPXV-B.1-China-C-Tan-CQ01.Infectious titration and PRNT methods have been developed.The study provides key resources and technical platforms for further research as well as anti-viral drug and vaccine development against MPX. | Baoying Huang Hua Zhao Jingdong Song Li Zhao Yao Deng Wen Wang Roujian Lu Wenling Wang Jiao Ren Fei Ye Houwen Tian Guizhen Wu Hua Ling Wenjie Tan | 2022 | China CDC weekly2022,4,46: | 3 |
| 12 | ACCURACY AND FLUENCY IN COMMUNICATIVE LANGUAGE TEACHING显示文摘Ⅰ. Introduction In English language teaching, at whatever level, teachers feel it very important to focus on accuracy and fluency in a pedagogic way. It is now widely accepted that neither of them should be focused on alone all the way through the teaching process. From our teaching experience, we can see that to some extent this is true. | Li Gang and Yan Guizhen Northwest Minority College | 2000 | Chinese Journal of Applied Linguistics2000,23,1: | 3 |
| 13 | Vehicle's fuel consumption of car-following models显示文摘Many car-following models with their own merits have been proposed to explore various traffic problems,but researchers have rarely used vehicle's performance to evaluate them.In this paper,we study each vehicle's fuel consumption of the optimal velocity model,full velocity difference model,full velocity and acceleration difference model and the car-following model with consideration of the traffic interruption probability under two traffic situations,respectively.The numerical results show that the car-following model with consideration of traffic interruption probability can reduce vehicle's fuel consumption in the two studied traffic situations and thus improve the vehicle's fuel economy. | TANG TieQiao LI JinGang WANG YunPeng YU GuiZhen | 2013 | Science China(Technological Sciences)2013,56,5: | 2 |

| 15 | Serological Investigation of Laboratory-Confirmed and Suspected Ebola Virus Disease Patients During the Late Phase of the Ebola Outbreak in Sierra Leone显示文摘This study aimed to investigate the serological characteristics of Ebola virus(EBOV) infection during the late phase of the Ebola outbreak in Sierra Leone. In total, 877 blood samples from 694 suspected Ebola virus disease(EVD) cases assessed from March to December 2015, were analyzed via real-time reverse transcription polymerase chain reaction(RT-PCR) for viral RNA and enzyme-linked immunosorbent assay(ELISA) and Luminex to detect antibodies against EBOV. Viral load and EBOV-specific IgM/IgG titers displayed a declining trend during March to December 2015. Viral RNA load decreased rapidly at earlier stages after disease onset, while EBOV-specific IgM and IgG still persisted in 58.1%(18/31) and 93.5%(29/31) of the confirmed EVD patients and in 3.8%(25/663) and 17.8%(118/663) of the RNA-negative suspected patients in the later phase, respectively. Dynamic analysis of longitudinally collected samples from eight EVD patients revealed typically reversed trends of declining viral load and increasing IgM and/or IgG titers in response to the EBOV infection.The present results indicate that certain populations of Sierra Leone developed immunity to an EBOV infection in the late phase of the outbreak, providing novel insights into the risk assessment of EBOV infections among human populations. | Yang Liu YuLan Sun Wei Wu AQian Li XianDa Yang Shuo Zhang Chuan Li QiuDong Su ShaoJian Cai DaPeng Sun HaiYang Hu Zhe Zhang XiuXu Yang Idrissa Kamara Sheku Koroma Gerald Bangura Alie Tia Abdul Kamara Matt Lebby Brima Kargbo Jiandong Li Shiwen Wang XiaoPing Dong YueLong Shu WenBo Xu George F.

| 16 | GmFtsH25 overexpression increases soybean seed yield by enhancing photosynthesis and photosynthates显示文摘Increasing plant photosynthetic capacity is a promising approach to boost yields,but it is particularly challenging in C3crops,such as soybean(Glycine max(L.)Merr.).Here,we identified GmFtsH25,encoding a member of the filamentation temperature-sensitive protein H protease family,as a major gene involved in soybean photosynthesis,using linkage mapping and a genome-wide association study.Overexpressing GmFtsH25 resulted in more grana thylakoid stacks in chloroplasts and increased photosynthetic efficiency and starch content,while knocking out GmFtsH25 produced the opposite phenotypes.GmFtsH25 interacted with photosystem I light harvesting complex 2(GmLHCa2),and this interaction may contribute to the observed enhanced photosynthesis.GmFtsH25 overexpression lines had superior yield traits,such as yield per plant,compared to the wild type and knockout lines.Additionally,we identified an elite haplotype of GmFtsH25,generated by natural mutations,which appears to have been selected during soybean domestication.Our study sheds light on the molecular mechanism by which GmFtsH25 modulates photosynthesis and provides a promising strategy for improving the yields of soybean and other crops. | Li Wang Yuming Yang Zhongyi Yang Wenlong Li Dezhou Hu Huilian Yu Xiao Li Hao Cheng Guizhen Kan Zhijun Che Dan Zhang Hengyou Zhang Hui Wang Fang Huang Deyue Yu | 2023 | Journal of Integrative Plant Biology2023,65,4: | 2 |

| 18 | Cartilage oligomeric matrix protein is an endogenous β-arrestin-2-selective allosteric modulator of AT1 receptor counteracting vascular injury显示文摘Compelling evidence has revealed that biased activation of G protein-coupled receptor(GPCR)signaling,including angiotensin II(AngII)receptor type 1(AT1)signaling,plays pivotal roles in vascular homeostasis and injury,but whether a clinically relevant endogenous biased antagonism of AT1 signaling exists under physiological and pathophysiological conditions has not been clearly elucidated.Here,we show that an extracellular matrix protein,cartilage oligomeric matrix protein(COMP),acts as an endogenous allosteric biased modulator of the AT1 receptor and its deficiency is clinically associated with abdominal aortic aneurysm(AAA)development.COMP directly interacts with the extracellular N-terminus of the AT1 via its EGF domain and inhibits AT1-β-arrestin-2 signaling,but not Gq or Gi signaling,in a selective manner through allosteric regulation of AT1 intracellular conformational states.COMP deficiency results in activation of AT1a-β-arrestin-2 signaling and subsequent exclusive AAA formation in response to AngII infusion.AAAs in COMP–/–or ApoE–/–mice are rescued by AT1a orβ-arrestin-2 deficiency,or the application of a peptidomimetic mimicking the AT1-binding motif of COMP.Explorations of the endogenous biased antagonism of AT1 receptor or other GPCRs may reveal novel therapeutic strategies for cardiovascular diseases. | Yi Fu Yaqian Huang Zhao Yang Yufei Chen Jingang Zheng Chenfeng Mao Zhiqing Li Zhixin Liu Bing Yu Tuoyi Li Meili Wang Chanjuan Xu Yiwei Zhou Guizhen Zhao Yiting Jia Wei Guo Xin Jia Tao Zhang Li Li Ziyi Liu Shengchao Guo Mingliang Ma Heng Zhang Bo Liu Junbao Du Wengong Wang Chaoshu Tang Pei Gao Qingbo Xu Xian Wang Jianfeng Liu Jinpeng Sun Wei Kong | 2021 | Cell Research2021,31,7: | 2 |

| 20 | Immunogenicity and safety of NVSI-06-07 as a heterologous booster after priming with BBIBP-CorV:a phase 2 trial显示文摘The increased coronavirus disease 2019(COVID-19)breakthrough cases pose the need of booster vaccination.We conducted a randomised,double-blinded,controlled,phase 2 trial to assess the immunogenicity and safety of the heterologous prime-boost vaccination with an inactivated COVID-19 vaccine(BBIBP-CorV)followed by a recombinant protein-based vaccine(NVSI-06-07),using homologous boost with BBIBP-CorV as control.Three groups of healthy adults(600 individuals per group)who had completed two-dose BBIBP-CorV vaccinations 1–3 months,4–6 months and≥6 months earlier,respectively,were randomly assigned in a 1:1 ratio to receive either NVSI-06-07 or BBIBP-CorV boost.Immunogenicity assays showed that in NVSI-06-07 groups,neutralizing antibody geometric mean titers(GMTs)against the prototype SARS-CoV-2 increased by 21.01–63.85 folds on day 28 after vaccination,whereas only 4.20–16.78 folds of increases were observed in control groups.For Omicron variant,the neutralizing antibody GMT elicited by homologous boost was 37.91 on day 14,however,a significantly higher neutralizing GMT of 292.53 was induced by heterologous booster.Similar results were obtained for other SARS-CoV-2 variants of concerns(VOCs),including Alpha,Beta and Delta.Both heterologous and homologous boosters have a good safety profile.Local and systemic adverse reactions were absent,mild or moderate in most participants,and the overall safety was quite similar between two booster schemes.Our findings indicated that NVSI-06-07 is safe and immunogenic as a heterologous booster in BBIBP-CorV recipients and was immunogenically superior to the homologous booster against not only SARS-CoV-2 prototype strain but also VOCs,including Omicron. | Nawal Al Kaabi Yun Kai Yang Jing Zhang Ke Xu Yu Liang Yun Kang Ji Guo Su Tian Yang Salah Hussein Mohamed Saif ElDein Shuai Shao Sen Sen Yang Wenwen Lei Xue Jun Gao Zhiwei Jiang Hui Wang Meng Li Hanadi Mekki Mekki Walid Zaher Sally Mahmoud Xue Zhang Chang Qu Dan Ying Liu Jing Zhang Mengjie Yang Islam Eltantawy Peng Xiao Zhao Nian Wang Jin Liang Yin Xiao Yan Mao Jin Zhang Ning Liu Fu Jie Shen Liang Qu Yun Tao Zhang Xiao Ming Yang Guizhen Wu Qi Ming Li | 2022 | Signal Transduction and Targeted Therapy2022,7,7: | 2 |
