| 1 | CD147-spike protein is a novel route for SARS-CoV-2 infection to host cells显示文摘In face of the everlasting battle toward COVID-19 and the rapid evolution of SARS-CoV-2,no specific and effective drugs for treating this disease have been reported until today.Angiotensin-converting enzyme 2(ACE2),a receptor of SARS-CoV-2,mediates the virus infection by binding to spike protein.Although ACE2 is expressed in the lung,kidney,and intestine,its expressing levels are rather low,especially in the lung.Considering the great infectivity of COVID-19,we speculate that SARS-CoV-2 may depend on other routes to facilitate its infection.Here,we first discover an interaction between host cell receptor CD147 and SARS-CoV-2 spike protein.The loss of CD147 or blocking CD147 in Vero E6 and BEAS-2B cell lines by anti-CD147 antibody,Meplazumab,inhibits SARSCoV-2 amplification.Expression of human CD147 allows virus entry into non-susceptible BHK-21 cells,which can be neutralized by CD147 extracellular fragment.Viral loads are detectable in the lungs of human CD147(hCD147)mice infected with SARS-CoV-2,but not in those of virus-infected wild type mice.Interestingly,virions are observed in lymphocytes of lung tissue from a COVID-19 patient.Human T cells with a property of ACE2 natural deficiency can be infected with SARS-CoV-2 pseudovirus in a dosedependent manner,which is specifically inhibited by Meplazumab.Furthermore,CD147 mediates virus entering host cells by endocytosis.Together,our study reveals a novel virus entry route,CD147-spike protein,which provides an important target for developing specific and effective drug against COVID-19. | Ke Wang Wei Chen Zheng Zhang Yongqiang Deng Jian-Qi Lian Peng Du Ding Wei Yang Zhang Xiu-Xuan Sun Li Gong Xu Yang Lei He Lei Zhang Zhiwei Yang Jie-Jie Geng Ruo Chen Hai Zhang Bin Wang Yu-Meng Zhu Gang Nan Jian-Li Jiang Ling Li Jiao Wu Peng Lin Wan Huang Liangzhi Xie Zhao-Hui Zheng Kui Zhang Jin-Lin Miao Hong-Yong Cui Min Huang Jun Zhang Ling Fu Xiang-Min Yang Zhongpeng Zhao Shihui Sun Hongjing Gu Zhe Wang Chun-Fu Wang Yacheng Lu Ying-Ying Liu Qing-Yi Wang Huijie Bian Ping Zhu Zhi-Nan Chen | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 9 |
| 2 | Light amplified oxidative stress in tumor microenvironment by carbonized hemin nanoparticles for boosting photodynamic anticancer therapy显示文摘Photodynamic therapy(PDT),which utilizes light excite photosensitizers(PSs)to generate reactive oxygen species(ROS)and consequently ablate cancer cells or diseased tissue,has attracted a great deal of attention in the last decades due to its unique advantages.However,the advancement of PDT is restricted by the inherent characteristics of PS and tumor microenvironment(TME).It is urgent to explore high-performance PSs with TME regulation capability and subsequently improve the therapeutic outcomes.Herein,we reported a newly engineered PS of polymer encapsulated carbonized hemin nanoparticles(P-CHNPs)via a facile synthesis procedure for boosting photodynamic anticancer therapy.Solvothermal treatment of hemin enabled the synthesized P-CHNPs to enhance oxidative stress in TME,which could be further amplified under light irradiation.Excellent in vitro and in vivo PDT effects were achieved due to the improved ROS(hydroxyl radicals and singlet oxygen)generation efficiency,hypoxia relief,and glutathione depletion.Moreover,the superior in vitro and in vivo biocompatibility and boosted PDT effect make the P-CHNPs a potential therapeutic agent for future translational research. | Liyun Lin Wen Pang Xinyan Jiang Shihui Ding Xunbin Wei Bobo Gu | 2022 | Light(Science & Applications)2022，11，3： | 2 |
| 3 | Super rigid tris-spirobifluorenes:Syntheses and properties显示文摘In this work,a blue emitter with a 3 D rigid structure composed of multiple spirobifluorene(3-Spiro) has been synthesized and characterized.Through a detailed study of the electrochemical and photophysical properties of 3-Spiro,we have evidenced that 3-Spiro can be applied as an active component of organic light-emitting diodes(OLEDs).The device with 5% doping rate of 4 CzPNPh exhibits high external quantum efficiency(EQE) of 11%,which proves the potential of 3 D rigid structure emitters for OLEDs. | Luyao Zhao Chunbo Duan Dongxue Ding Shihui Liu Debin Xia Ying Guo Hui Xu Martin Baumgartend | 2021 | Chinese Chemical Letters2021，32，1： | 1 |
| 4 | prpf4 is essential for cell survival and posterior lateral line primordium migration in zebrafish显示文摘Prpf4(pre-mRNA processing factor 4),a key component of spliceosome,plays critical roles in pre-mRNA splicing and its mutations result in retinitis pigmentosa due to photoreceptor defects.In this study,we characterized a zebrafishharboring a Tol2 transposon-based gene trap cassette in the third intron of the prpf4 gene.Cells in the brain and spinal cord gradually undergo p53-dependent apoptosis after 28 hpf insuggesting that a widespread function of prpf4 in neural cell survival.In addition,prpf4 is essential for survival of posterior lateral line primordial(pLLP)cells.prpf4 deficiency perturbs Fgf,and chemokine signaling pathways and impairs pLLP migration.RNA-Seq analysis suggests that prpf4 deficiency may impair spliceosome assembly,leading to compensatory upregulation of core spliceosomal genes and alteration of pre-mRNA splicing.Taken together,our studies uncover an essential role of prpf4 in pre-m RNA splicing,cell survival and pLLP migration. | Yixia Wang Yanchao Han Pengfei Xu Shihui Ding Guangyuan Li Hongbin Jin Yaping Meng Anming Meng Shunji Jia | 2018 | Journal of Genetics and Genomics2018，45，8： | 1 |
| 5 | Low back pain and osteoarthritis pain:a perspective of estrogen显示文摘Low back pain(LBP)is the world's leading cause of disability and is increasing in prevalence more rapidly than any other pain condition.Intervertebral disc(IVD)degeneration and facet joint osteoarthritis(FJOA)are two common causes of LBP,and both occur more frequently in elderly women than in other populations.Moreover,osteoarthritis(OA)and OA pain,regardless of the joint,are experienced by up to twice as many women as men,and this difference is amplified during menopause.Changes in estrogen may be an important contributor to these pain states.Receptors for estrogen have been found within IVD tissue and nearby joints,highlighting the potential roles of estrogen within and surrounding the IVDs and joints.In addition,estrogen supplementation has been shown to be effective at ameliorating IVD degeneration and OA progression,indicating its potential use as a therapeutic agent for people with LBP and OA pain.This review comprehensively examines the relationship between estrogen and these pain conditions by summarizing recent preclinical and clinical findings.The potential molecular mechanisms by which estrogen may relieve LBP associated with IVD degeneration and FJOA and OA pain are discussed. | Huiwen Pang Shihui Chen David M.Klyne David Harrich Wenyuan Ding Sidong Yang Felicity Y.Han | 2023 | Bone Research2023，11，3： | 0 |
| 6 | Screening HLA-A-restricted T cell epitopes of SARS-CoV-2 and the induction of CD8^(+)T cell responses in HLA-A transgenic mice显示文摘Since severe acute respiratory syndrome coronavirus-2(SARS-CoV-2)-specific T cells have been found to play essential roles in host immune protection and pathology in patients with coronavirus disease 2019(COVID-19),this study focused on the functional validation of T cell epitopes and the development of vaccines that induce specific T cell responses.A total of 120 CD8^(+)T cell epitopes from the E,M,N,S,and RdRp proteins were functionally validated.Among these,110,15,6,14,and 12 epitopes were highly homologous with SARS-CoV,OC43,NL63,HKU1,and 229E,respectively;in addition,four epitopes from the S protein displayed one amino acid that was distinct from the current SARS-CoV-2 variants.Then,31 epitopes restricted by the HLA-A2 molecule were used to generate peptide cocktail vaccines in combination with Poly(I:C),R848 or poly(lactic-co-glycolic acid)nanoparticles,and these vaccines elicited robust and specific CD8^(+)T cell responses in HLA-A2/DR1 transgenic mice as well as wild-type mice.In contrast to previous research,this study established a modified DC-peptide-PBL cell coculture system using healthy donor PBMCs to validate the in silico predicted epitopes,provided an epitope library restricted by nine of the most prevalent HLA-A allotypes covering broad Asian populations,and identified the HLA-A restrictions of these validated epitopes using competitive peptide binding experiments with HMy2.CIR cell lines expressing the indicated HLA-A allotype,which initially confirmed the in vivo feasibility of 9-or 10-mer peptide cocktail vaccines against SARS-CoV-2.These data will facilitate the design and development of vaccines that induce antiviral CD8^(+)T cell responses in COVID-19 patients. | Xiaoxiao Jin Yan Ding Shihui Sun Xinyi Wang Zining Zhou Xiaotao Liu Miaomiao Li Xian Chen Anran Shen Yandan Wu Bicheng Liu Jianqiong Zhang Jian Li Yi Yang Haibo Qiu Chuanlai Shen Yuxian He Guangyu Zhao | 2021 | Cellular & Molecular Immunology2021，18，12： | 0 |
