1The use of supercytokines, immunocytokines, engager cytokines, and other synthetic cytokines in immunotherapy显示文摘Cytokines exert powerful immunomodulatory effects that are critical to physiology and pathology in humans.The application of natural cytokines in clinical studies has not been clearly established,and there are often problems associated with toxicity or lack of efficacy.The key reasons can be attributed to the pleiotropy of cytokine receptors and undesired activation of off-target cells.With a deeper understanding of the structural principles and functional signals of cytokine-receptor interactions,artificial modification of cytokine signaling through protein engineering and synthetic immunology has become an increasingly feasible and powerful approach.Engineered cytokines are designed to selectively target cells.Herein,the theoretical and experimental evidence of cytokine engineering is reviewed,and the“supercytokines”resulting from structural enhancement and the“immunocytokines”generated by antibody fusion are described.Finally,the“engager cytokines”formed by the crosslinking of cytokines and bispecific immune engagers and other synthetic cytokines formed by nonnatural analogs are also discussed.Xiaohu Zheng Yaqi Wu Jiacheng Bi Yingying Huang Ying Cheng Yangyang Li Yuwei Wu Guoshuai Cao Zhigang Tian 2022Cellular & Molecular Immunology2022,19,2:4
2Robust architecture of 2D nano Mg-based borohydride on graphene with superior reversible hydrogen storage performance显示文摘Efficient technical strategies to synthesize hydrides with high capacity and favorable reversibility are significant for the development of novel energy materials.Herein,nano Mg-based borohydride,Mg(BH_(4))_(2),with robust architecture was designed and prepared by confining on graphene through a solution selfconfinement method.The Mg(BH_(4))_(2) confined on graphene displays a wrinkled 2D nano layer morphology within 8.8 nm thickness.Such 2D nano Mg(BH_(4))_(2) can start dehydrogenation at 67.9℃ with a high capacity of 12.0 wt.%,which is 190.5℃ lower than pristine Mg(BH_(4))_(2).The isothermal dehydrogenation tests and kinetics fitting results indicate the 2D nano Mg(BH_(4))_(2) possesses much-enhanced dehydrogenation kinetics of 31.3 kJ/mol activation energy,which is only half of pristine Mg(BH_(4))_(2).The thermodynamics of the 2D nano Mg(BH_(4))_(2) is also verified by PCT tests,of which Gibbs free energy value for the confined 2D nano Mg(BH_(4))_(2) is estimated to be-18.01 kJ/mol H_(2),lower than-16.36 kJ/mol H_(2) of pristine Mg(BH_(4))_(2).Importantly,the reversibility of the confined 2D nano Mg(BH_(4))_(2) is significantly enhanced to over 90%capacity retention with relatively kinetics stability during 10 cycles.The mechanism analyses manifest that Mg(BH_(4))_(2) exhibits stable 2D nano morphology during 10 cyclic tests,resulting in the greatly reduced H diffusion path and the improved de/rehydrogenation kinetics of the 2D nano Mg(BH_(4))_(2).Based on theoretical calculations of Mg(BH_(4))_(2) and the intermediate MgB12H12 confined on graphene,the charge transfer status of both samples is modified to facilitate de/rehydrogenation,thus leading to the significant thermodynamic improvements of the reversible hydrogen storage performances for 2D nano Mg(BH_(4))_(2).Such investigation of the Mg-based borohydride will illuminate prospective technical research of energy storage materials.Xuancheng Wang Yuxiao Jia Xuezhang Xiao Panpan Zhou Jiapeng Bi Jiacheng Qi Ling Lv Fen Xu Lixian Sun Lixin Chen 2023Journal of Materials Science & Technology2023,,15:0
3CD226:a potent driver of antitumor immunity that needs to be maintained显示文摘Inhibitory receptors expressed on the immune cell surface have emerged as checkpoint molecules that could be therapeutically targeted for tumor immunotherapy.However,antitumor immunity mediated by checkpoint blockade depends on optimal recognition of tumor cells through the activation of receptors on antitumor effector immune cells,such as CD8^(+)T cells and NK cells.Therefore,sufficient and maintained expression levels of activating receptors on these effector immune cells are essential for antitumor immunity and checkpoint blockade immunotherapy.Jiacheng Bi 2022Cellular & Molecular Immunology2022,19,9:0
4Regulating local chemistry in ZrCo-based orthorhombic hydrides via increasing atomic interference for ultra-stable hydrogen isotopes storage显示文摘Developing a universal and reliable strategy for the modulation of composition and structure of energy storage materials with stable cycling performance is vital for hydrogen and its isotopes storage advanced system,yet still challenging.Herein,an ultra-stable lattice structure is designed and verified to increase atomic chaos and interference for effectively inhibiting disproportionation reaction and improving cycling stability in ZrCo-based hydrogen isotopes storage alloy.After screening in terms of configuration entropy calculation,we construct Zr_(1-2)Nb_(x)Co_(1-2x)Cu_(x)Ni_(x)(x=0.15,0.2,0.25) alloys with increased atomic chaos,and successfully achieve stable isostructural de-/hydrogenation during 100 cycles,whose cycling capacity retentions are above 99%,much higher than 22.4%of pristine ZrCo alloy.Both theoretical analysis and experimental evidences indicate the high thermo-stability of orthorhombic lattice in Zr_(0.8)Nb_(0.2)Co_(0.6)Cu_(0.2)Ni_(0.2) alloy.Notably,the increased atomic chaos and interference in Zr_(0.8)Nb_(0.2)Co_(0.6)Cu_(0.2)Ni_(0.2) alloy causes regulation in hydrogen local chemical neighborhood,thereby confusing the hydrogen release order,which effectively eliminates lattice distortion and unlocks an ultrastable lattice structure.This study provides a new and comprehensive inspiration for hydrogen atoms transport behaviors and intrinsic reason of stable orthorhombic transformation,which can contribute to paving the way for other energy storage materials modulation.Zhaoqing Liang Zhendong Yao Ruhong Li Xuezhang Xiao Zhichao Ye Xuancheng Wang Jiacheng Qi Jiapeng Bi Xiulin Fan Huaqin Kou Wenhua Luo Changan Chen Lixin Chen 2022Journal of Energy Chemistry2022,31,6:0
5NK cell dysfunction in patients with COVID-19显示文摘A substantial proportion of patients with coronavirus disease 2019(COVID-19)caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection might develop severe pneumonia and fibrotic lung damage at later stages after the infection.Efficient antiviral immunity and prevention of fibrosis progression are critical for COVID-19 control.Natural killer(NK)cells,whose targeting strategies have already provided therapeutic benefits in immunotherapy against tumors,are innate lymphocytes that also play an important role in antiviral immunity.In support of targeting NK cells in patients with COVID-19,Krämer et al.recently provided evidence that NK cells display anti-SARS-CoV-2 activity[1].They showed that purified peripheral NK cells from healthy individuals reduce viral protein levels in cocultured SARS-CoV-2-infected cells.Jiacheng Bi 2022Cellular & Molecular Immunology2022,19,2:0
6A review of classical hydrogen isotopes storage materials显示文摘Hydrogen storage alloys(HSAs)are attracting widespread interest in the nuclear industry because of the generation of stable metal hydrides after tritium absorption,thus effectively preventing the leakage of radioactive tritium.Commonly used HSAs in the hydrogen isotopes field are Zr2M(M=Co,Ni,Fe)alloys,metallic Pd,depleted U,and ZrCo alloy.Specifically,Zr2M(M=Co,Ni,Fe)alloys are considered promising tritium-getter materials,and metallic Pd is utilized to separate and purify hydrogen isotopes.Furthermore,depleted U and ZrCo alloy are well suited for storing and delivering hydrogen isotopes.Notably,all the aforementioned HSAs need to modulate their hydrogen storage properties for complex operating conditions.In this review,we present a comprehensive overview of the reported modification methods applied to the above alloys.Alloying is an effective amelioration method that mainly modulates the properties of HSAs by altering their local geometrical/electronic structures.Besides,microstructural modifications such as nano-sizing and nanopores have been used to increase the specific surface area and active sites of metallic Pd and ZrCo alloys for enhancing de-/hydrogenation kinetics.The combination of metallic Pd with support materials can significantly reduce the cost and enhance the pulverization resistance.Moreover,the poisoning resistance of ZrCo alloy is improved by constructing active surfaces with selective permeability.Overall,the review is constructive for better understanding the properties and mechanisms of hydrogen isotope storage alloys and provides effective guidance for future modification research.Yang Liu Zhiyi Yang Panpan Zhou Xuezhang Xiao Jiacheng Qi Jiapeng Bi Xu Huang Huaqin Kou Lixin Chen 2024Materials Reports(Energy)2024,4,1:0
