| 1 | Genetically modified CD7-targeting allogeneic CAR-T cell therapy with enhanced efficacy for relapsed/refractory CD7-positive hematological malignancies:a phase I clinical study显示文摘Chimeric antigen receptor(CAR)-T cell therapy against T cell malignancies faces major challenges including fratricide between CAR-T cells and product contamination from the blasts.Allogeneic CAR-T cells,generated from healthy donor T cells,can provide ready-to-use,blast-free therapeutic products,but their application could be complicated by graft-versus-host disease(GvHD)and host rejection.Here we developed healthy donor-derived,CD7-targeting CAR-T cells(RD13-01)with genetic modifications to resist fratricide,GvHD and allogeneic rejection,as well as to potentiate antitumor function.A phase I clinical trial(NCT04538599)was conducted with twelve patients recruited(eleven with T cell leukemia/lymphoma,and one with CD7-expressing acute myeloid leukemia).All patients achieved pre-set end points and eleven proceeded to efficacy evaluation.No dose-limiting toxicity,GvHD,immune effector cell-associated neurotoxicity or severe cytokine release syndrome(grade≥3)were observed.28 days post infusion,81.8%of patients(9/11)showed objective responses and the complete response rate was 63.6%(7/11,including the patient with AML).3 of the responding patients were bridged to allogeneic hematopoietic stem cell transplantation.With a median follow-up of 10.5 months,4 patients remained in complete remission.Cytomegalovirus(CMV)and/or Epstein-Barr virus(EBV)reactivation was observed in several patients,and one died from EBV-associated diffuse large B-cell lymphoma(DLBCL).Expansion of CD7-negative normal T cells was detected post infusion.In summary,we present the first report of a Phase I clinical trial using healthy donor-derived CD7-targeting allogeneic CAR-T cells to treat CD7^(+)hematological malignancies.Our results demonstrated the encouraging safety and efficacy profiles of the RD13-01 allogeneic CAR-T cells for CD7^(+)tumors. | Yongxian Hu Yali Zhou Mingming Zhang Houli Zhao Guoqing Wei Wengang Ge Qu Cui Qitian Mu Gong Chen Lu Han Tingting Guo Jiazhen Cui Xiaoyan Jiang Xiujun Zheng Shuhui Yu Xiaolong Li Xingwang Zhang Mingxi Chen Xiuju Li Ming Gao Kang Wang Cheng Zu Hao Zhang Xiaohong He Yanbin Wang Dongrui Wang Jiangtao Ren He Huang | 2022 | Cell Research2022，32，11： | 2 |
| 2 | Design of bifunctional single-atom catalysts NiSA/ZIF-300 for CO_(2) conversion by ligand regulation strategy显示文摘Carbon-supported noble-metal-free single-atom catalysts(SACs)have aroused widespread interest due to their green chemistry aspects and excellent performances.Herein,we propose a“ligand regulation strategy”and achieve the successful fabrication of bifunctional SAC/MOF(MOF=metal-organic framework)nanocomposite(abbreviated NiSA/ZIF-300;ZIF=ZIF-8)with exceptional catalytic performance and robustness.The designed NiSA/ZIF-300 has a planar interfacial structure with the Ni atom,involving one S and three N atoms bonded to Ni(Ⅱ),fabricated by controllable pyrolysis of volatile Ni-S fragments.For CO_(2) cycloaddition to styrene epoxide,NiSA/ZIF-300 exhibits ultrahigh activity(turnover number(TON)=1.18×105;turnover frequency(TOF)=9830 molSC·mol_(Ni)^(-1)·h^(-1);SC=styrene carbonate)and durability at 70℃ under 1 atm CO_(2) pressure,which is much superior to Ni complex/ZIF,NiNP/ZIF-300,and most reported catalysts.This study offers a simple method of bifunctional SAC/MOF nanocomposite fabrication and usage,and provides guidance for the precise design of additional original SACs with unique catalytic properties. | Wengang Fu Yapei Yun Hongting Sheng Xiaokang Liu Tao Ding Shuxian Hu Tao Yao Binghui Ge Yuanxin Du Didier Astruc Manzhou Zhu | 2024 | Nano Research2024，17，5： | 0 |
| 3 | Efficient ternary organic solar cells based on a twin spiro-type non-fullerene acceptor显示文摘A novel small-molecule(SM) acceptor DTF-IC is designed and synthesized in this work. The power conversion efficiency(PCE) of ternary OSCs increased up to 12.14% from 10.90% by incorporating 10 wt% of DTF-IC as second acceptors into the binary OSCs consisting of PBDB-T as donor and IT-M as acceptor. This was mainly due to the large increase in short-circuit current(Jsc) from 16.18 to 17.95 mA/cm^2, without any drop in the open-circuit voltage(Voc) and fill factor(FF). The addition of DTF-IC enabled the donor and acceptor to form a distinct complementary absorption profile in the visible-light region, which boosted the photon harvesting in the range of 730–800 nm and consequently increased the Jscof the ternary system by 11%. Moreover, there was an energy transfer between the two SM acceptors, favorable for enhancing charge separation and transfer as well as reducing charge recombination at PBDB-T:IT-M and PBDB-T:DTF-IC interface. Simultaneously, HOMO and LUMO energy levels of DTF-IC were lower than those of PBDB-T, but still higher than those of IT-M. Thus, DTF-IC is able to provide a cascading energy level with the host donor and acceptor which are beneficial for efficient charge transfer between the acceptors and facilitating exciton dissociation and carrier transport. Meanwhile, the highly crystalline DTF-IC as a third component can improve the crystallization process of the active layer while maintaining proper phase separation. This work proposes a novel idea for non-fullerene acceptors achieved via twin spiro-type structure modifying by indanone and provides a new direction for the selection of ternary solar cell materials. | Lirong Wu Lingchao Xie Hanmin Tian Ruixiang Peng Jiaming Huang Billy Fanady Wei Song Songting Tan Wengang Bi Ziyi Ge | 2019 | Science Bulletin2019，64，15： | 0 |
