2CCL5/CCR5 axis in human diseases and related treatments显示文摘To defense harmful stimuli or maintain the immune homeostasis, the body produces and recruits a superfamily of cytokines such as interleukins, interferons, chemokines etc. Among them, chemokines act as crucial regulators in defense systems. CCL5/CCR5 combination is known for facilitating inflammatory responses, as well as inducing the adhesion and migration of different T cell subsets in immune responses. In addition, recent studies have shown that the interaction between CCL5 and CCR5 is involved in various pathological processes including inflammation, chronic diseases, cancers as well as the infection of COVID-19. This review focuses on how CCL5/CCR5 axis participates in the pathological processes of different diseases and their relevant signaling pathways for the regulation of the axis. Moreover, we highlighted the gene therapy and chemotherapy studies for treating CCR5-related diseases, including the ongoing clinical trials. The barriers and perspectives for future application and translational research were also summarized.Zhen Zeng Tianxia Lan Yuquan Wei Xiawei Wei 2022Genes & Diseases2022,9,1:12
3Mitochondrial DNA in the regulation of innate immune responses显示文摘线粒体作为房间的精力工厂被知道,它也是一个唯一的哺乳动物的细胞器并且考虑超过 10 亿年以前从氧气的初核质被发展。Mitochondrial DNA,类似于它的细菌的祖先,由一个圆形的环组成并且作为 CpG 岛包含 unmethylated DNA 的重要数字。天生的免疫系统在哺乳动物的有免疫力的反应起一个重要作用。最近的研究证明了 mitochondrial DNA (mtDNA ) 激活包含发信号的 TLR9, NLRP3 和圈套的几条天生的有免疫力的小径,它在受动器回答贡献发信号的平台和结果。除了便于抗菌剂豁免并且调整抗病毒的发信号,装证据建议 mtDNA 贡献跟随细胞的损坏和应力的煽动性的疾病。除了它在细胞的新陈代谢和精力生产的欣赏得好的角色,因此, mtDNA 看起来在天生的免疫系统作为一个关键成员工作。这里,我们在天生的免疫加亮 mtDNA 的新兴的角色。Chunju Fang Xiawei Wei Yuquan Wei 2016Protein & Cell2016,7,1:12
4JMJD3 in the regulation of human diseases显示文摘In recent years,many studies have shown that histone methylation plays an important role in maintaining the active and silent state of gene expression in human diseases.The Jumonji domain-containing protein D3(JMJD3),specifically demethylate di-and trimethyllysine 27 on histone H3(H3K27me2/3),has been widely studied in immune diseases,infectious diseases,cancer,developmental diseases,and aging related diseases.We will focus on the recent advances of JMJD3 function in human diseases,and looks ahead to the future of JMJD3 gene research in this review.Xiangxian Zhang Li Liu Xia Yuan Yuquan Wei Xiawei 2019Protein & Cell2019,10,12:10
5Epigenetic regulation of macrophages: from homeostasis maintenance to host defense显示文摘Macrophages are crucial members of the innate immune response and important regulators.The differentiation and activation of macrophages require the timely regulation of gene expression,which depends on the interaction of a variety of factors,including transcription factors and epigenetic modifications.Epigenetic changes also give macrophages the ability to switch rapidly between cellular programs,indicating the ability of epigenetic mechanisms to affect phenotype plasticity.In this review,we focus on key epigenetic events associated with macrophage fate,highlighting events related to the maintenance of tissue homeostasis,responses to different stimuli and the formation of innate immune memory.Further understanding of the epigenetic regulation of macrophages will be helpful for maintaining tissue integrity,preventing chronic inflammatory diseases and developing therapies to enhance host defense.Siyuan Chen Jing Yang Yuquan Wei Xiawei Wei 2020Cellular & Molecular Immunology2020,17,1:8
6Molecular mechanisms and clinical management of cancer bone metastasis显示文摘As one of the most common metastatic sites of malignancies,bone has a unique microenvironment that allows metastatic tumor cells to grow and flourish.The fenestrated capillaries in the bone,bone matrix,and bone cells,including osteoblasts and osteoclasts,together maintain the homeostasis of the bone microenvironment.In contrast,tumor-derived factors act on bone components,leading to subsequent bone resorption or excessive bone formation.The various pathways involved also provide multiple targets for therapeutic strategies against bone metastases.In this review,we summarize the current understanding of the mechanism of bone metastases.Based on the general process of bone metastases,we specifically highlight the complex crosstalk between tumor cells and the bone microenvironment and the current management of cancer bone metastases.Manni Wang Fan Xia Yuquan Wei Xiawei Wei 2020Bone Research2020,8,3:7
7Spontaneous apoptosis of cells in therapeutic stem cell preparation exert immunomodulatory effects through release of phosphatidylserine显示文摘Mesenchymal stem cell(MSC)-mediated immunomodulation has been harnessed for the treatment of human diseases,but its underlying mechanism has not been fully understood.Dead cells,including apoptotic cells have immunomodulatory properties.It has been repeatedly reported that the proportion of nonviable MSCs in a MSC therapeutic preparation varied from 5-50%in the ongoing clinical trials.It is conceivable that the nonviable cells in a MSC therapeutic preparation may play a role in the therapeutic effects of MSCs.We found that the MSC therapeutic preparation in the present study had about 5%dead MSCs(DMSCs),characterized by apoptotic cells.Namely,1×10^(6) MSCs in the preparation contained about 5×10^(4) DMSCs.We found that the treatment with even 5×10^(4) DMSCs alone had the equal therapeutic effects as with 1×10^(6) MSCs.This protective effect of the dead MSCs alone was confirmed in four mouse models,including concanavalin A(ConA)-and carbon tetrachloride(CCI4)-induced acute liver injury,LPS-induced lung injury and spinal cord injury.We also found that the infused MSCs died by apoptosis in vivo.Furthermore,the therapeutic effect was attributed to the elevated level of phosphatidylserine(PS)upon the injection of MSCs or DMSCs.The direct administration of PS liposomes(PSLs)mimic apoptotic cell fragments also exerted the protective effects as MSCs and DMSCs.The Mer tyrosine kinase(MerTK)deficiency or the knockout of chemokine receptor C-C motif chemokine receptor 2(CCR2)reversed these protective effects of MSCs or DMSCs.These results revealed that DMSCs alone in the therapeutic stem cell preparation or the apoptotic cells induced in vivo may exert the same immunomodulatory property as the'living MSCs preparation'through releasing PS,which was further recognized by MerTK and participated in modulating immune cells.Xuemei He Weiqi Hong Jingyun Yang Hong Lei Tianqi Lu Cai He Zhenfei Bi Xiangyu Pan Yu Liu Lunzhi Dai Wei Wang Canhua Huang Hongxin Deng Xiawei Wei 2021Signal Transduction and Targeted Therapy2021,6,8:6
8Multifunctional regulatory protein connective tissue growth factor (CTGF):A potential therapeutic target for diverse diseases显示文摘Connective tissue growth factor(CTGF),a multifunctional protein of the CCN family,regulates cell proliferation,differentiation,adhesion,and a variety of other biological processes.It is involved in the disease-related pathways such as the Hippo pathway,p53 and nuclear factor kappa-B(NF-κB)pathways and thus contributes to the developments of inflammation,fibrosis,cancer and other diseases as a downstream effector.Therefore,CTGF might be a potential therapeutic target for treating various diseases.In recent years,the research on the potential of CTGF in the treatment of diseases has also been paid more attention.Several drugs targeting CTGF(monoclonal antibodies FG3149 and FG3019)are being assessed by clinical or preclinical trials and have shown promising outcomes.In this review,the cellular events regulated by CTGF,and the relationships between CTGF and pathogenesis of diseases are systematically summarized.In addition,we highlight the current researches,focusing on the preclinical and clinical trials concerned with CTGF as the therapeutic target.Minyang Fu Dandan Peng Tianxia Lan Yuquan Wei Xiawei Wei 2022Acta Pharmaceutica Sinica B2022,12,4:5
9Targeting folate receptorβpositive tumor-associated macrophages in lung cancer with a folate-modified liposomal complex显示文摘Tumor-associated macrophages(TAMs)facilitate cancer progression by promoting tumor invasion,angiogenesis,metastasis,inflammatory responses,and immunosuppression.Folate receptorβ(FRβ)is overexpressed in TAMs.However,the clinical significance of FRβ-positive macrophages in lung cancer remains poorly understood.In this study,we verified that FRβoverexpression in lung cancer TAMs was associated with poor prognosis.We utilized a folate-modified lipoplex comprising a folatemodified liposome(F-PLP)delivering a BIM-S plasmid to target both lung cancer cells and FRβ-positive macrophages in the tumor microenvironment.Transfection of LL/2 cells and MH-S cells with F-PLP/pBIM induced cell apoptosis.Injection of F-PLP/pBIM into LL/2 and A549 lung cancer models significantly depleted FRβ-positive macrophages and reduced tumor growth.Treatment of tumor-bearing mice with F-PLP/pBIM significantly inhibited tumor growth in vivo by inducing tumor cell and macrophage apoptosis,reducing tumor proliferation,and inhibiting tumor angiogenesis.In addition,a preliminary safety evaluation demonstrated a good safety profile of F-PLP/pBIM as a gene therapy administered intravenously.This work describes a novel application of lipoplexes in lung cancer targeted therapy that influences the tumor microenvironment by targeting TAMs.Yan Tie Heng Zheng Zhiyao He Jingyun Yang Bin Shao Li Liu Min Luo Xia Yuan Yu Liu Xiangxian Zhang Hongyi Li Min Wu Xiawei Wei 2020Signal Transduction and Targeted Therapy2020,5,1:4
10Nucleic acids and analogs for bone regeneration显示文摘With the incidence of different bone diseases increasing, effective therapies are needed that coordinate a combination of various technologies and biological materials. Bone tissue engineering has also been considered as a promising strategy to repair various bone defects. Therefore, different biological materials that can promote stem cell proliferation, migration, and osteoblastic differentiation to accelerate bone tissue regeneration and repair have also become the focus of research in multiple fields. Stem cell therapy, biomaterial scaffolds, and biological growth factors have shown potential for bone tissue engineering; however, off-target effects and cytotoxicity have limited their clinical use. The application of nucleic acids(deoxyribonucleic acid or ribonucleic acid)and nucleic acid analogs(peptide nucleic acids or locked nucleic acids), which are designed based on foreign genes or with special structures, can be taken up by target cells to exert different effects such as modulating protein expression, replacing a missing gene, or targeting specific gens or proteins. Due to some drawbacks, nucleic acids and nucleic acid analogs are combined with various delivery systems to exert enhanced effects, but current studies of these molecules have not yet satisfied clinical requirements. In-depth studies of nucleic acid or nucleic acid analog delivery systems have been performed, with a particular focus on bone tissue regeneration and repair. In this review, we mainly introduce delivery systems for nucleic acids and nucleic acid analogs and their applications in bone repair and regeneration. At the same time, the application of conventional scaffold materials for the delivery of nucleic acids and nucleic acid analogs is also discussed.Yuxin Zhang Wenjuan Ma Yuxi Zhan Chenchen Mao Xiaoru Shao Xueping Xie Xiawei Wei Yunfeng Lin 2018Bone Research2018,6,4:3

12In-cell infection: a novel pathway for Epstein-Barr virus infection mediated by cell-in-cell structures显示文摘Chao Ni Yuhui Chen Musheng Zeng Rongjuan Pei Yong Du Linquan Tang Mengyi Wang Yazhuo Hu Hanyu Zhu Meifang He Xiawei Wei Shan Wang Xiangkai Ning Manna Wang Jufang Wang Li Ma Xinwen Chen Qiang Sun Hong Tang Ying Wang Xiaoning Wang 2015Cell Research2015,25,7:3
13A new and promising application of gene editing: CRISPR-controlled smart materials for tissue engineering,bioelectronics, and diagnostics显示文摘A recent study published in the journal Science by Collins et al.proposed a programmable clustered regularly interspaced short palindromic repeats(CRISPR)-responsive smart material containing the CRISPR-associated nuclease,Casl2a,and hydrogels containing DNA to deliver biological information via changes in material properties(English et al.,2019).Weiqi Hong Mengyuan Huang Yuquan Wei Xiawei Wei 2019Science China(Life Sciences)2019,62,11:3
14Oxidized mitochondrial DNA sensing by STING signaling promotes the antitumor effect of an irradiated immunogenic cancer cell vaccine显示文摘Exposure to ionizing radiation,a physical treatment that inactivates live tumor cells,has been extensively applied to enhance the antitumor responses induced by cancer cell vaccines in both animal research and human clinical trials.However,the mechanisms by which irradiated cells function as immunogenic tumor vaccines and induce effective antitumor responses have not been fully explored.Here,we demonstrate that oxidized mitochondrial DNA(mtDNA)and stimulator of interferon genes(STING)signaling play a key roles in the enhanced antitumor effect achieved with an irradiated tumor cell vaccine.Elevations in ROS and oxidized mtDNA 8-OHG content could be induced in irradiated tumor cells.Oxidized mtDNA derived from irradiated tumor cells gained access to the cytosol of dendritic cells(DCs).Oxidized mtDNA,as a DAMP or adjuvant,activated the STING-TBK1-IRF3-IFN-β pathway in DCs,which subsequently cross-presented irradiated tumor cell-derived antigens to CD8^(+)T cells and elicited antitumor immunity.The results of our study provide insight into the mechanism by which an irradiated cell vaccine mediates antitumor immunity,which may have implications for new strategies to improve the efficacy of irradiated vaccines.Chunju Fang Fei Mo Li Liu Jing Du Min Luo Ke Men Feifei Na Wei Wang Hanshuo Yang Xiawei Wei 2021Cellular & Molecular Immunology2021,18,9:2
15Histones 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
16Role of tumor gene mutations in treatment response to immune checkpoint blockades显示文摘Early studies shed light on the immune suppression of immune checkpoint molecules in the cancer microenvironment,with later studies applying immune checkpoint blockade(ICB)in treatment of various malignancies.Despite the encouraging efficacy of ICBs in a substantial subset of cancer patients,the treatment response varies.Gene mutations of both tumor cells and immune cells in the tumor microenvironment have recently been identified as potential predictors of the ICB response.Recent developments in gene expression profiling of tumors have allowed identification of a panel of mutated genes that may affect tumor cell response to ICB treatment.In this review,we discuss the association of the ICB response with gene expression and mutation profiles in tumor cells,which it is hoped will help to optimize the clinical application of ICBs in cancer patients.Manni Wang Liu Yu Xiawei Wei Yuquan Wei 2019Precision Clinical Medicine2019,2,2:2
17DNA-PK inhibition by M3814 enhances chemosensitivity in non-small cell lung cancer显示文摘A significant proportion of non-small cell lung cancer(NSCLC) patients experience accumulating chemotherapy-related adverse events,motivating the design of chemosensitizating strategies.The main cytotoxic damage induced by chemotherapeutic agents is DNA double-strand breaks(DSB).It is thus conceivable that DNA-dependent protein kinase(DNA-PK) inhibitors which attenuate DNA repair would enhance the anti-tumor effect of chemotherapy.The present study aims to systematically evaluate the efficacy and safety of a novel DNA-PK inhibitor M3814 in synergy with chemotherapies on NSCLC.We identified increased expression of DNA-PK in human NSCLC tissues which was associated with poor prognosis.M3814 potentiated the anti-tumor effect of paclitaxel and etoposide in A549,H460 and H1703 NSCLC cell lines.In the four combinations based on two NSCLC xenograft models and two chemotherapy,we also observed tumor regression at tolerated doses in vivo.Moreover,we identified a P53-dependent accelerated senescence response by M3814 following treatment with paclitaxel/etoposide.The present study provides a theoretical basis for the use of M3814 in combination with paclitaxel and etoposide in clinical practice,with hope to aid the optimization of NSCLC treatment.Manni Wang Siyuan Chen Yuquan Wei Xiawei Wei 2021Acta Pharmaceutica Sinica B2021,11,12:2
18The molecular mechanisms of MLKL-dependent and MLKL-independent necrosis显示文摘Necrosis,a type of unwanted and passive cell demise,usually occurs under the excessive external stress and is considered to be unregulated.However,under some special conditions such as caspase inhibition,necrosis is regulable in a well-orchestrated way.The term'regulated necrosis'has been proposed to describe such programed necrosis.Recently,several forms of necrosis,including necroptosis,pyroptosis,ferroptosis,parthanatos,oxytosis,NETosis,and Na^(+)/K^(+)ATPasimediated necrosis,have been identified,and some crucial regulators governing regulated necrosis have also been discovered.Mixed lineage kinase domain-like pseudokinase(MLKL),a core regulator in necroptosis,acts as an executioner in response to ligands of death receptor family.Its activation requires the receptor-interacting protein kinases,RIP1 and RIP3.However,MLKL is only involved in necroptosis,i.e.MLKL is dispensable for necrosis.Therefore,this review is aimed at summarizing the molecular mechanisms of MLKLdependent and MLKL-independent necrosis.Lu Li An Tong Qiangsheng Zhang Yuquan Wei Xiawei Wei 2021Journal of Molecular Cell Biology2021,13,1:2
19Ketogenic diet for human diseases:the underlying mechanisms and potential for clinical implementations显示文摘The ketogenic diet(KD)is a high-fat,adequate-protein,and very-low-carbohydrate diet regimen that mimics the metabolism of the fasting state to induce the production of ketone bodies.The KD has long been established as a remarkably successful dietary approach for the treatment of intractable epilepsy and has increasingly garnered research attention rapidly in the past decade,subject to emerging evidence of the promising therapeutic potential of the KD for various diseases,besides epilepsy,from obesity to malignancies.In this review,we summarize the experimental and/or clinical evidence of the efficacy and safety of the KD in different diseases,and discuss the possible mechanisms of action based on recent advances in understanding the influence of the KD at the cellular and molecular levels.We emphasize that the KD may function through multiple mechanisms,which remain to be further elucidated.The challenges and future directions for the clinical implementation of the KD in the treatment of a spectrum of diseases have been discussed.We suggest that,with encouraging evidence of therapeutic effects and increasing insights into the mechanisms of action,randomized controlled trials should be conducted to elucidate a foundation for the clinical use of the KD.Huiyuan Zhu Dexi Bi Youhua Zhang Cheng Kong Jiahao Du Xiawei Wu Qing Wei Huanlong Qin 2022Signal Transduction and Targeted Therapy2022,7,2:2
