| 1 | A lipid-based LMP2-mRNA vaccine to treat nasopharyngeal carcinoma显示文摘Nasopharyngeal carcinoma(NPC)is a serious and highly invasive epithelial malignancy that is closely associated with Epstein‒Barr virus(EBV).Due to the lack of therapeutic vaccines for NPC,we selected EBV latent membrane protein 2(LMP2)as a preferable targeting antigen to develop a lipid-based LMP2-mRNA(mLMP2)vaccine.Full-length mLMP2 expressing LMP2 was first synthesized using an in vitro transcription method and then encapsulated into(2,3-dioleacyl propyl)trimethylammonium chloride(DOTAP)-based cationic liposomes to obtain the mRNA vaccine(LPX-mLMP2).The cell assays showed that the antigenpresenting cells were capable of highly efficient uptake of LPX-mLMP2 and expression of LMP2.LMP2 could subsequently be presented to form the peptide-major histocompatibility complex(pMHC).Furthermore,LPX-mLMP2 could accumulate in the spleen,express antigens,promote the maturation of dendritic cells and stimulate antigen-specific T-cell responses in vivo.It dramatically inhibited the tumor growth of the LMP2-expressing tumor model after three doses of vaccination.Additionally,the proliferation of antigen-specific T cells in the tumor site made a good sign for the promise of mRNA vaccines in virus-induced cancer.Overall,we provided a newly developed antigen-encoding mRNA vaccine with advantages against NPC.We also demonstrated that mRNA vaccines are attractive candidates for cancer immunotherapy. | Mengran Guo Xing Duan Xingchen Peng Zhaohui Jin Hai Huang Wen Xiao Qian Zheng Yongqi Deng Na Fan Kepan Chen Xiangrong Song | 2023 | Nano Research2023，16，4： | 1 |
| 2 | Geology, environment, and life in the deepest part of the world’s oceans显示文摘The hadal zone,mostly comprising of deep trenches and constituting of the deepest part of the world’s oceans,represents the least explored habitat but one of the last frontiers on our planet.The present scientific understanding of the hadal environment is still relatively rudimentary,particularly in comparison with that of shallower marine environments.In the last 30 years,continuous efforts have been launched in deepening our knowledge regarding the ecology of the hadal trench.However,the geological and environmental processes that potentially affect the sedimentary,geochemical and biological processes in hadal trenches have received less attention.Here,we review recent advances in the geology,biology,and environment of hadal trenches and offer a perspective of the hadal science involved therein.For the first time,we release highdefinition images taken by a new full-ocean-depth manned submersible Fendouzhe that reveal novel species with an unexpectedly high density,outcrops of mantle and basaltic rocks,and anthropogenic pollutants at the deepest point of the world’s ocean.We advocate that the hydration of the hadal lithosphere is a driving force that influences a variety of sedimentary,geochemical,and biological processes in the hadal trench.Hadal lithosphere might host the Earth’s deepest subsurface microbial ecosystem.Future research,combined with technological advances and international cooperation,should focus on establishing the intrinsic linkage of the geology,biology,and environment of the hadal trenches. | Mengran Du Xiaotong Peng Haibin Zhang Cong Ye Shamik Dasgupta Jiwei Li Jiangtao Li Shuangquan Liu Hengchao Xu Chuanxu Chen Hongmei Jing Hongzhou Xu Jun Liu Shunping He Lisheng He Shanya Cai Shun Chen Kaiwen Ta | 2021 | The Innovation2021，2，2： | 0 |
| 3 | π-Extension and chlorination of non-fullerene acceptors enable more readily processable and sustainable high-performance organic solar cells显示文摘Organic solar cells(OSCs)processed without halogenated solvents and complex treatments are essential for future commercialization.Herein,we report three novel small molecule acceptors(NFAs)consisting of a Y6-like core but withπ-extended naphthalene with progressively more chlorinated end-capping groups and a longer branched chain on the Nitrogen atom.These NFAs exhibit good solubilities in nonchlorinated organic solvents,broad optical absorptions,closeπ-πstacking distances(3.63–3.84A),and high electron mobilities(~10^(-3)cm^(2)V^(-1)s^(-1)).The o-xylene processed and as-cast binary devices using PM6 as the donor polymer exhibit a PCE increasing upon progressive chlorination of the naphthalene end-capping group from 8.93%for YN to 14.38%for YN-Cl to 15.00%for YN-2Cl.Furthermore similarly processed ternary OSCs were fabricated by employing YN-Cl and YN-2Cl as the third component of PM6:CH1007 blends(PCE=15.75%).Compared to all binary devices,the ternary PM6:CH1007:YN-Cl(1:1:0.2)and PM6:CH1007:YN-2Cl(1:1:0.2)cells exhibit significantly improved PCEs of 16.49%and15.88%,respectively,which are among the highest values reported to date for non-halogenated solvent processed OSCs without using any additives and blend post-deposition treatments. | Ning Su Jianhua Chen Mengran Peng Guoping Li Robert M.Pankow Ding Zheng Junqiao Ding Antonio Facchetti Tobin J.Marks | 2023 | Journal of Energy Chemistry2023，，4： | 0 |
