| 1 | Tuning charge density of chimeric antigen receptor optimizes tonic signaling and CAR-T cell fitness显示文摘Tonic signaling of chimeric antigen receptor(CAR),i.e.,the spontaneous CAR activation in the absence of tumor antigen stimulation,is considered to be a pivotal event controlling CAR-T efficacy.However,the molecular mechanism underlying the spontaneous CAR signals remains elusive.Here,we unveil that positively charged patches(PCPs)on the surface of the CAR antigenbinding domain mediate CAR clustering and result in CAR tonic signaling.For CARs with high tonic signaling(e.g.,GD2.CAR and CSPG4.CAR),reducing PCPs on CARs or boosting ionic strength in the culture medium during ex vivo CAR-T cell expansion minimizes spontaneous CAR activation and alleviates CAR-T cell exhaustion.In contrast,introducing PCPs into the CAR with weak tonic signaling,such as CD19.CAR,results in improved in vivo persistence and superior antitumor function.These results demonstrate that CAR tonic signaling is induced and maintained by PCP-mediated CAR clustering.Notably,the mutations we generated to alter the PCPs maintain the antigen-binding affinity and specificity of the CAR.Therefore,our findings suggest that the rational tuning of PCPs to optimize tonic signaling and in vivo fitness of CAR-T cells is a promising design strategy for the nextgeneration CAR. | Jian Chen Shizhen Qiu Wentao Li Kun Wang Yu Zhang Han Yang Baichuan Liu Guangfei Li Li Li Min Chen Junjie Lan Jiahua Niu Peijie He Lei Cheng Gaofeng Fan Xin Liu Xianmin Song Chenqi Xu Haitao Wu Haopeng Wang | 2023 | Cell Research2023，33，5： | 2 |
| 2 | Simulation of the anode structure for capacitive Frisch grid CdZnTe detectors显示文摘CdZnTe(CZT)capacitive Frisch grid detectors can achieve a higher detecting resolution.The anode structure might have an important role in improving the weighting potential distribution of the detectors.In this paper, four anode structures of capacitive Frisch grid structures have been analyzed with FE simulation,based on a 3-dimensional weighting potential analysis.The weighting potential distributions in modified anode devices(Model B, C and D)are optimized compared with a square device(Model A).In model C and D,the abrupt weighting potential can be well modified.However,with increased radius of the circular electrode in Model C the weighting potential platform away from the anode becomes higher and higher and in Model D,the weighting potential does not vary too much. | MIN Jiahua SHI Zhubin QIAN Yongbiao SANG Wenbin ZHAO Hengyu TENG Jianyong LIU Jishan | 2009 | Nuclear Science and Techniques2009，20，1： | 2 |
| 3 | Mapping Domain- and Age-Specific Functional Brain Activity for Children’s Cognitive and Affective Development显示文摘The human brain undergoes rapid development during childhood,with significant improvement in a wide spectrum of cognitive and affective functions.Mapping domain-and age-specific brain activity patterns has important implications for characterizing the development of children’s cognitive and affective functions.The current mainstay of brain templates is primarily derived from structural magnetic resonance imaging(MRI),and thus is not ideal for mapping children’s cognitive and affective brain development.By integrating task-dependent functional MRI data from a large sample of 250 children(aged 7 to 12)across multiple domains and the latest easy-to-use and transparent preprocessing workflow,we here created a set of age-specific brain functional activity maps across four domains:attention,executive function,emotion,and risky decision-making.Moreover,we developed a toolbox named Developmental Brain Functional Activity maps across multiple domains that enables researchers to visualize and download domain-and age-specific brain activity maps for various needs.This toolbox and maps have been released on the Neuroimaging Informatics Tools and Resources Clearinghouse website(http://gffzza9adc041c78b4b3bhv0cxcc5u90bv6pk5.ffgz.tsg.suse.edu.cn/projects/dbfa).Our study provides domain-and age-specific brain activity maps for future developmental neuroimaging studies in both healthy and clinical populations. | Lei Hao Lei Li Menglu Chen Jiahua Xu Min Jiang Yanpei Wang Linhua Jiang Xu Chen Jiang Qiu Shuping Tan Jia-Hong Gao Yong He Sha Tao Qi Dong Shaozheng Qin | 2021 | Neuroscience Bulletin2021，37，6： | 1 |

| 10 | Control of large linear magnetoelectricity in Co_(3)NiNb_(2)O_(9)显示文摘Magnetoelectric(ME)materials have caught worldwide attentions owing to their potential technological applications in ME switching devices or high-density data storage.However,realizing a sufficiently strong ME effect in one single material is always the key issue.Herein,we systematically investigate the Co_(3)NiNb_(2)O_(9),including the characterization of its crystalline structure,magnetism,specific heat,and pyroelectric properties.It is revealed that Co_(3)NiNb_(2)O_(9) exhibits a remarkable ME response below the magnetic phase transition temperature of TN-32 K.On one hand,the magnetic field-induced electric polarization is observed below TN while it is non-ferroelectric at no magnetic field.The evaluated ME coefficient is as large as 21.2 ps/m.On the other hand,the magnetization is significantly modulated by the applied electric field,with the inverse ME coefficient being 14.1 ps/m.The observed ME responses suggest a stable ME mutual control by the magnetic or electric field in Co_(3)NiNb_(2)O_(9). | Xiang Li Yu Wang Meifeng Liu Yunlong Xie Jiahua Min Xiyu Chen Jingwen Gong Leiyu Li Min Zeng Yiming Xu Yiru Wang Biwen Li Xiuzhang Wang Jun-Ming Liu | 2021 | Journal of Materiomics2021，7，4： | 0 |
| 11 | Annealing High Resistivity CdZnTe Wafers under Controlled Cd/Zn Partial Pressures显示文摘In order to improve the performances of CdZnTe γ-ray detector, it is key issue to get the crystal with high quality. Equilibrium partial pressures, PCd and PZn, over Cd1-xZnx melt were estimated based on thermodynamic relationship and then Cd0.9Zn0.1Te wafers were annealed under controlled Cd/Zn partial pressures provided by Cd1-xZnx alloy reservoir. The experimental results show that when CdZnTe wafers are annealed under the equilibrium partial pressures provided by Cd0.99Zn0.01 alloy reservoir for 5 days or more at 1073 K, the resistivity of the wafer can be raised by 6 times and IR transmittance raised by 10% or more, the size and density of Te precipitates are greatly reduced.Moreover, losing of Zn from the surface can be avoided, which leads to improvement of the Zn radial distribution.In addition, the relationship between the electrical performances of the wafers and different controlled pressures is also discussed. | Wanwan LI, Wenbin SANG, Bin ZHANG, Jiahua MIN and Fang YUSchool of Material Science and Engineering, Jiading Campus, Shanghai University, Shanghai 201800, ChinaInstitute of Composites Materials, Shanghai Jiao Tong University, Shanghai 200030, China | 2004 | Journal of Materials Science & Technology2004，20，6： | 0 |
