| 1 | Propane dehydrogenation catalyzed by in-situ partially reduced zinc cations confined in zeolites显示文摘Propane dehydrogenation(PDH), employing Pt-or Cr-based catalysts, represents an emerging industrial route for propylene production. Due to the scarcity of platinum and the toxicity of chromium, alternative PDH catalysts are being pursued. Herein, we report the construction of Zn-containing zeolite catalysts,namely Zn@S-1, for PDH reaction. Well-isolated zinc cations are successfully trapped and stabilized by the Si-OH groups in S-1 zeolites via in-situ hydrothermal synthesis. The as-prepared Zn@S-1 catalysts exhibit good dehydrogenation activity, high propylene selectivity, and regeneration capability in PDH reaction under employed conditions. The in-situ partial reduction of zinc species is observed and the partially reduced zinc cations are definitely identified as the active sites for PDH reaction. | Linjun Xie Rui Wang Yuchao Chai Xuefei Weng Naijia Guan Landong Li | 2021 | Journal of Energy Chemistry2021，30，12： | 4 |
| 2 | Emerging phagocytosis checkpoints in cancer immunotherapy显示文摘Cancer immunotherapy,mainly including immune checkpoints-targeted therapy and the adoptive transfer of engineered immune cells,has revolutionized the oncology landscape as it utilizes patients’own immune systems in combating the cancer cells.Cancer cells escape immune surveillance by hijacking the corresponding inhibitory pathways via overexpressing checkpoint genes.Phagocytosis checkpoints,such as CD47,CD24,MHC-I,PD-L1,STC-1 and GD2,have emerged as essential checkpoints for cancer immunotherapy by functioning as“don’t eat me”signals or interacting with“eat me”signals to suppress immune responses.Phagocytosis checkpoints link innate immunity and adaptive immunity in cancer immunotherapy.Genetic ablation of these phagocytosis checkpoints,as well as blockade of their signaling pathways,robustly augments phagocytosis and reduces tumor size.Among all phagocytosis checkpoints,CD47 is the most thoroughly studied and has emerged as a rising star among targets for cancer treatment.CD47-targeting antibodies and inhibitors have been investigated in various preclinical and clinical trials.However,anemia and thrombocytopenia appear to be formidable challenges since CD47 is ubiquitously expressed on erythrocytes.Here,we review the reported phagocytosis checkpoints by discussing their mechanisms and functions in cancer immunotherapy,highlight clinical progress in targeting these checkpoints and discuss challenges and potential solutions to smooth the way for combination immunotherapeutic strategies that involve both innate and adaptive immune responses. | Yu’e Liu Yanjin Wang Yanrong Yang Linjun Weng Qi Wu Jin Zhang Pengcheng Zhao Lan Fang Yufeng Shi Ping Wang | 2023 | Signal Transduction and Targeted Therapy2023，8，4： | 1 |
| 3 | Identification of Glutaminyl Cyclase isoenzyme isoQC as a regulator of SIRPα-CD47 axis显示文摘Dear Editor,Cancer cells often upregulate the expression of ligands for the inhibitory immune checkpoints receptor to escape anti-tumor immunity1. Targeting inhibitory immune checkpoints has become one of the most promising anticancer therapeutic inventions. Infiltration of myeloid cells, especially phagocytic cells, to tumors is often associated with chemotherapy resistance and progression of various cancer types. Phagocytosis of cancer cells is the major mechanism for these myeloid cells-mediated antitumor activity. However, many types of cancer cells express high level of ‘don’t eat me’ signals on the cell surface to escape the phagocytic cells-mediated antitumor immunity. | Zhiqiang Wu Linjun Weng Tengbo Zhang Hongling Tian Lan Fang Hongqi Teng Wen Zhang Jing Gao Yun Hao Yaxu Li Hu Zhou Ping Wang | 2019 | Cell Research2019，29，6： | 1 |

| 5 | PD-L1 regulates genomic stability via interaction with cohesin-SAl in the nucleus显示文摘Dear Editor,Programmed death ligand-1(PD-L1)is a type 1 transmembrane protein and highly expressed in various cancers that binds to PD-1 on T cells,inhibits T cell activity and proliferation,facilitates cancer cells to escape T cell-mediated immune surveillance.Immunotherapies by PD-L1/PD-1 blockade have shown effectiveness against different cancer types and revolutionizes cancer treatment in the clinic.However,the response rate to anti-PD-L1/PD-1 antibody remains at about 15-30%as a single agent.1 Thus,there is more to understand regarding the function of PD-L1 in cancer. | Wen Zhang Jiali Jin Yanjin Wang Lan Fanq Liu Min Xinbo Wang Lin Ding Linjun Weng Tan Xiao Tianhua Zhou Ping Wang | 2021 | Signal Transduction and Targeted Therapy2021，6，3： | 0 |
| 6 | Cloud-Type-Dependent 1DVAR Algorithm for Retrieving Hydrometeors and Precipitation in Tropical Cyclone Nanmadol from GMI Data显示文摘Understanding the structure of tropical cyclone(TC)hydrometeors is crucial for detecting the changes in the distribution and intensity of precipitation.In this study,the GMI brightness temperature and cloud-dependent 1DVAR algorithm were used to retrieve the hydrometeor profiles and surface rain rate of TC Nanmadol(2022).The Advanced Radiative Transfer Modeling System(ARMS)was used to calculate the Jacobian and degrees of freedom(△DOF)of cloud water,rainwater,and graupel for different channels of GMI in convective conditions.The retrieval results were compared with the Dual-frequency Precipitation Radar(DPR),GMI 2A,and IMERG products.It is shown that from all channels of GMI,rain water has the highest△DOF,at 1.72.According to the radiance Jacobian to atmospheric state variables,cloud water emission dominates its scattering.For rain water,the emission of channels 1–4 dominates scattering.Compared with the GMI 2A precipitation product,the 1DVAR precipitation rate has a higher correlation coefficient(0.713)with the IMERG product and can better reflect the location of TC precipitation.Near the TC eyewall,the highest radar echo top indicates strong convection.Near the melting layer where Ka-band attenuation is strong,the double frequency difference of DPR data reflects the location of the melting.The DPR drop size distribution(DSD)product shows that there is a significant increase in particle size below the melting layer in the spiral rain band.Thus,the particle size may be one of the main reasons for the smaller rain water below the melting layer retrieved from 1DVAR. | Linjun HAN Fuzhong WENG Hao HU Xiuqing HU | 2024 | Advances in Atmospheric Sciences2024，41，3： | 0 |
