| 1 | Abrogation of Hn RNP L enhances anti-PD-1 therapy efficacy via diminishing PD-L1 and promoting CD8^(+) T cell-mediated ferroptosis in castration-resistant prostate cancer显示文摘Owing to incurable castration-resistant prostate cancer(CRPC)ultimately developing after treating with androgen deprivation therapy(ADT),it is vital to devise new therapeutic strategies to treat CRPC.Treatments that target programmed cell death protein 1(PD-1)and programmed death ligand-1(PD-L1)have been approved for human cancers with clinical benefit.However,many patients,especially prostate cancer,fail to respond to anti-PD-1/PD-L1 treatment,so it is an urgent need to seek a support strategy for improving the traditional PD-1/PD-L1 targeting immunotherapy.In the present study,analyzing the data from our prostate cancer tissue microarray,we found that PD-L1 expression was positively correlated with the expression of heterogeneous nuclear ribonucleoprotein L(Hn RNP L).Hence,we further investigated the potential role of Hn RNP L on the PD-L1 expression,the sensitivity of cancer cells to T-cell killing and the synergistic effect with anti-PD-1 therapy in CRPC.Indeed,Hn RNP L knockdown effectively decreased PD-L1 expression and recovered the sensitivity of cancer cells to T-cell killing in vitro and in vivo,on the contrary,Hn RNP L overexpression led to the opposite effect in CRPC cells.In addition,consistent with the previous study,we revealed that ferroptosis played a critical role in T-cell-induced cancer cell death,and Hn RNP L promoted the cancer immune escape partly through targeting YY1/PD-L1 axis and inhibiting ferroptosis in CRPC cells.Furthermore,Hn RNP L knockdown enhanced antitumor immunity by recruiting infiltrating CD8^(+)T cells and synergized with anti-PD-1 therapy in CRPC tumors.This study provided biological evidence that Hn RNP L knockdown might be a novel therapeutic agent in PD-L1/PD-1 blockade strategy that enhanced anti-tumor immune response in CRPC. | Xumin Zhou Libin Zou Hangyu Liao Junqi Luo Taowei Yang Jun Wu Wenbin Chen Kaihui Wu Shengren Cen Daojun Lv Fangpeng Shu Yu Yang Chun Li Bingkun Li Xiangming Mao | 2022 | Acta Pharmaceutica Sinica B2022，12，2： | 4 |

| 4 | Solution-processed,flexible and broadband photodetector based on CsPbBr_(3)/PbSe quantum dot heterostructures显示文摘Due to their promising applications in foldable displays,optical communication equipment and environmental monitoring systems,flexible and broadband optoelectronic devices have gained extensive attention in recent years.Here,a flexible and broadband photodetector based on CsPbBr_(3)/PbSe quantum dot(QD) heterostructures is firstly presented.The integrated QD heterostructures possess consecutive detection range from ultraviolet(UV) to long-wave length infrared(LW-IR) regions with efficient light absorption and chemical stability,in comparison with the pristine PbSe QDs.Systematic material characterizations reveal the improved exciton dissociation,carrier transport and carrier lifetime of the QD heterostructures.Flexible photodetector Ag/CsPbBr_(3)/PbSe/Ag demonstrate a high responsivity of 7.17 A/W with a specific detectivity of 8.97 × 10^(12) Jones under 25 μW/cm^(2) 365 nm illumination at 5 V.Furthermore,it could maintain 91.2 %(or 94.9 %) of its initial performance even after bending for thousands of times(or exposing in ambient air for 4 weeks).More importantly,its re s ponse time is shortened more than three orders of magnitude as that of pristine PbSe QDs-based photodetectors.Therefore,it provides a feasible and promising method for the next-generation high-performance broadband photodetectors via constructing heterostructures of various QDs. | Jinming Hu Shengyi Yang Zhenheng Zhang Hailong Li Chandrasekar Perumal Veeramalai Muhammad Sulaman Muhammad Imran Saleem Yi Tang Yurong Jiang Libin Tang Bingsuo Zou | 2021 | Journal of Materials Science & Technology2021，，9： | 1 |
| 5 | CsPbI nanorods as the interfacial layer for high-performance,all-solution-processed self-powered photodetectors显示文摘Heterojunction is regarded as a crucial step toward realizing high-performance devices,particularly,forming gradient energy band between heterojunctions benefits self-powered photodetectors.Therefore,in this paper,the synthesis of CsPbI3 nanorods(NRs)and its application as the interfacial layer in high-performance,all-solution-processed self-powered photodetectors are presented.For the bilayer photodetector ITO/ZnO(100 nm)/PbS-TBAI(150 nm)/Au,a responsivity of 3.6 A/W with a specific detectivity of 9.8×10^(12)Jones was obtained under 0.1 mW/cm^(2)white light illumination at zero bias(i.e.in self-powered mode).Meanwhile,the photocurrent was enhanced to an On/Off current ratio of 105 at zero bias with an open circuit voltage of 0.53 V for trilayer photodetector ITO/ZnO(100 nm)/PbSTBAI(150 nm)/CsPbI3(250 nm)/Au,in which the CsPbI3 NRs layer works as the interfacial layer.As a result,a specific detectivity of 4.5×10^(13)Jones with a responsivity of 11.12 A/W was obtained under0.1 mW/cm^(2) white light illumination,as well as the rising/decaying time of 0.57 s/0.41 s with excellent stability and reproducibility upto four weeks in air.The enhanced-performance is ascribed to the mismatch bandgap between PbS-TBAI/CsPbI_(3)interface,which can suppress the carrier recombination and provide efficient transport passages for charge carriers.Thus,it provides a feasible and efficient method for high-performance photodetectors. | Muhammad Imran Saleem Shangyi Yang Attia Batool Muhammad Sulaman Chandrasekar Perumal Veeramalai Yurong Jiang Yi Tang Yanyan Cui Libin Tang Bingsuo Zou | 2021 | Journal of Materials Science & Technology2021，，16： | 1 |
| 6 | Multifunctional all-polymer photovoltaic blend with simultaneously improved efficiency(18.04%),stability and mechanical durability显示文摘One of the most appealing material systems for solar energy conversion is allpolymer blend.Presently,the three key merits(power conversion efficiency,operation stability and mechanical robustness)exhibited a trade-off in a particular all-polymer blend system,which greatly limit its commercial application.Diverting the classic ternary tactic of organic solar cells based on polymer,nonfullerene small molecule and fullerene,herein we demonstrate that the three merits of a benchmark all-polymer blend PM6:PY-IT can be simultaneously maximized via the introduction of a polymerized fullerene derivative PPCBMB.Importantly,the addition of the guest component promoted the power conversion efficiency of PM6:PY-IT blend from 16.59%to 18.04%.Meanwhile,the device stability and film ductility are also improved due to the addition of this polymerized fullerene material.Morphology and device physics analyses reveal that optimal ternary system contains well-maintained molecular packing and crystallinity,being beneficial to keeping favorable charge transport and the reduced domain size contributed to charge generation and ductility improvement.Furthermore,the ternary photovoltaic blend was successfully used as photocatalysts,and an excellent heavy metal removal from water was demonstrated.This study showcases the multi-functions of all-polymer blends via the use of polymerized fullerenes. | Tao Liu Kangkang Zhou Ruijie Ma Libin Zhang Ciyuan Huang Zhenghui Luo Hongxiang Zhu Shangfei Yao Chuluo Yang Bingsuo Zou Long Ye | 2023 | Aggregate2023，4，3： | 0 |
