| 1 | Immunogenicity and protective efficacy of a recombinant protein subunit vaccine and an inactivated vaccine against SARS-CoV-2 variants in non-human primates显示文摘Emerging SARS-CoV-2 variants and the gradually decreasing neutralizing antibodies over time post vaccination have led to an increase in incidents of breakthrough infection across the world.To investigate the potential protective effect of the recombinant protein subunit COVID-19 vaccine targeting receptor-binding domain(RBD)(PS-RBD)and whole inactivated virus particle vaccine(IV)against the variant strains,in this study,rhesus macaques were immunized with PS-RBD or IV vaccine,followed by a Beta variant(B.1.351)challenge.Although neutralizing activity against the Beta variant was reduced compared with that against the prototype,the decreased viral load in both upper and lower respiratory tracts,milder pathological changes,and downregulated inflammatory cytokine levels in lung tissues after challenge demonstrated that PS-RBD and IV still provided effective protection against the Beta variant in the macaque model.Furthermore,PS-RBD-induced macaque sera possessed general binding and neutralizing activity to Alpha,Beta,Delta,and Omicron variants in our study,though the neutralizing antibody(NAb)titers declined by varying degrees,demonstrating potential protection of PS-RBD against current circulating variants of concern(VOCs).Interestingly,although the IV vaccine-induced extremely low neutralizing antibody titers against the Beta variant,it still showed reduction for viral load and significantly alleviated pathological change.Other correlates of vaccine-induced protection(CoP)like antibody-dependent cellular cytotoxicity(ADCC)and immune memory were both confirmed to be existing in IV vaccinated group and possibly be involved in the protective mechanism. | Qian He Qunying Mao Xiaozhong Peng Zhanlong He Shuaiyao Lu Jialu Zhang Fan Gao Lianlian Bian Chaoqiang An Wenhai Yu Fengmei Yang Yanan Zhou Yun Yang Yanyan Li Yadi Yuan Xujia Yan Jinghuan Yang Xing Wu Weijin Huang Changgui Li Junzhi Wang Zhenglun Liang Miao Xu | 2022 | Signal Transduction and Targeted Therapy2022，7，4： | 2 |
| 2 | Non-small cell lung cancers(NSCLCs)oncolysis using coxsackievirus B5 and synergistic DNA-damage response inhibitors显示文摘With the continuous in-depth study of the interaction mechanism between viruses and hosts,the virus has become a promising tool in cancer treatment.In fact,many oncolytic viruses with selectivity and effectiveness have been used in cancer therapy.Human enterovirus is one of the most convenient sources to generate oncolytic viruses,however,the high seroprevalence of some enteroviruses limits its application which urges to exploit more oncolytic enteroviruses. | Bopei Cui Lifang Song Qian Wang Kelei Li Qian He Xing Wu Fan Gao Mingchen Liu Chaoqiang An Qiushuang Gao Chaoying Hu Xiaotian Hao Fangyu Dong Jiuyue Zhou Dong Liu Ziyang Song Xujia Yan Jialu Zhang Yu Bai Qunying Mao Xiaoming Yang Zhenglun Liang | 2023 | Signal Transduction and Targeted Therapy2023，8，10： | 0 |
| 3 | Miro2 supplies a platform for Parkin translocation to damaged mitochondria显示文摘PINK1/Parkin-mediated mitophagy is an important process in selective removal of damaged mitochondria, in which translocation of Parkin to damaged mitochondria is recognized as an initiation step. At present, how the damaged mitochondria are selectively recognized and targeted by Parkin is not fully understood. Here we show that Miro2, an outer mitochondrial membrane protein, undergoes demultimerization from a tetramer to a monomer and alteration in mitochondrial localization upon CCCP treatment, suggesting a CCCP-induced realignment of Miro2. The realignment of Miro2 is tightly regulated by PINK1-mediated phosphorylation at Ser325/Ser430 and by Ca^2+binding to EF2 domain, which are both essential for the subsequent Parkin translocation. Interestingly, ablation of Miro2 in mouse causes delayed reticulocyte maturation, lactic acidosis and cardiac disorders. Furthermore, several Miro2 mutations found in the congenital lactic acidosis patients also disable its realignment and Parkin translocation. These findings reveal an important role of Miro2 to mediate Parkin translocation by sensing both depolarization and Ca^2+release from damaged mitochondria to ensure the accuracy of mitophagy. | Jiu-Qiang Wang Shu Zhu Yihan Wang Fengli Wang Chaoqiang An Dongfang Jiang Lijie Gao Yingfeng Tu Xuefei Zhu Yun Wang Hongmei Liu Juanjuan Gong Zhongshuai Sun Xi Wang Leimei Liu Keyan Yang Caixia Guo Tie-Shan Tang | 2019 | Science Bulletin2019，64，11： | 0 |
