Paired Immunoglobin-like Receptors A and B Are New Targets for Inducing Dendritic Cells Tolerance in Mice

引用

Journal of Huazhong University of Science and Technology(Medical Sciences) 2007年第3期27卷 252-256页

作者：刘峥嵘黎纬明张敏周浩韩红邹萍 Institute of Hematology Union Hospital Tongji Medical College Huazhong University of Science and Technology

The expression of paired immunoglobin-like receptors A (PIR-A) and B (PIR-B) and their relationship with tolerogenic dendritic cells (T-DC) in mice were investigated. The mouse DCs line, DC2.4 cells were cultured with the recombinant murine interleukin-10 (IL-10) and recombinant human transforming growth factor β1 (TGF-β1) respectively to develop the T-DC and stimulated with lipopolysaccharide (LPS) for 48 h to induce the mature dendritic cells (LPS-DC). Special small interfering RNAs (siRNA) molecule for PIR-B was chemically synthesized and transfected into DC2.4 cells (Si-DC) by lip2000. The expression of PIRs on DC2.4 cells were detected by semi-quantitative reverse transcription polymerase chain reaction (RT-PCR), flow cytometry (FCM) and Western blot. Realtime reverse transcriptase-polymerase chain reaction (Realtime-PCR) was ap- plied for measurement of PIR-A and CD80, CD86, MHC-Ⅱ mRNA expression. The allogeneic stimulating capacity of DCs was measured by mixed lymphocyte reaction (MLR) using 3H-thymidine incorporation test. The concentration of IFN-γ in supernatants of MLR from distinct groups was ana- lyzed by ELISA. The results showed that PIR positive rate was (28.65±8.12)% examined by FCM on DC2.4 cells. PIR positive rate was increased dramatically to (54.21±6.34)%, (58.78±4.70)%, (48.24±6.75)% respectively for IL-10, TGF-β1 and LPS induction (P0.01). The semi-quantitative RT-PCR and Western blot revealed that IL-10 and TGF-β1 induced the higher PIR-B level and lower PIR-A level. On the contrary, the LPS down-regulated the PIR-B expression and up-regulated the PIR-A expression. Realtime PCR examination demonstrated that PIR-A and co-stimulating molecules such as CD80, CD86 and MHC-Ⅱ were increased significantly after stimulation with LPS. Compared with the DC2.4 cells and the LPS-DC, the T-DCs inhibited alloactived T cell proliferation and down-regulated the IFN-γ secretion in ML

Dear Editor, Phenotypic drug discovery, which observes compound effects on physiology,has given way to targeting specific molecules, but has revived by using modern methods to find drugs based on therapeutic outcomes in disease models(Vincent et al., 2022). Osteoarthritis(OA) is a prevalent chronic joint disorder, primarily affecting knee joints, with osteoclast activation due to low-grade inflammation resulting in increased bone resorption and structural changes in the joint(Katz et al.,2021).

机器翻译(machine translation, MT)研究旨在构建一个自动转换系统,将给定源语言序列自动地转换为具有相同语义的目标语言序列.由于机器翻译广阔的应用场景,使其成为自然语言理解领域乃至人工智能领域的一个重要的研究方向.近年来,端到端的神经机器翻译(neural machine translation, NMT)方法显著超越了统计机器翻译(statistical machine translation, SMT)方法,成为目前机器翻译研究的主流方法.然而,神经机器翻译系统通常以句子为翻译单位,在面向文档的翻译场景中,将文档中每个句子独立地进行翻译,会因脱离文档的篇章语境引起一些篇章级的错误,如词语错翻、句子间不连贯等.因此将文档级的信息融入到翻译的过程中去解决跨句的篇章级错误是更加自然和合理的做法,文档级的神经机器翻译(document-level neural machine translation, DNMT)的目标正是如此,成为机器翻译研究的热门方向.调研了近年来在文档级神经机器翻译研究方向的主要工作,从篇章评测方法、使用的数据集和模型方法等方面系统地对当前研究工作进行了归纳与阐述,目的是帮助研究者们快速了解文档级神经机器翻译研究现状以及未来的发展和研究方向.同时在文中也阐述了在文档级神经机器翻译的一些展望、困难和挑战,希望能带给研究者们一些启发.

Chinese Journal of Structural Chemistry 2005年第11期24卷 1324-1327页

作者： YIN han-Dong GAO Zhong-Jun LI Gang XU hao-Long HONG min Department of Chemistry Liaocheng University Liaocheng 252059 China

A novel organotin complex [（n-Bu）3Sn（OCOC5H4NO）]n has been synthesized and characterized by elemental analysis, IR and ^1H NMR. The crystal structure has been determined by X-ray single-crystal diffraction. The crystal belongs to monoclinic, space group P2 1/c with a = 8.982（2）, b = 17.908（4）, c = 13.219（3） A, β= 96.981（4）°, Z = 4, V= 2110.6（8） A^3, Dc = 1.347 g/cm^3, μ（MoKa） = 12.23 cm^-1, F（000） = 880, R = 0.0497 and wR = 0.1263. In the molecular structure of the title complex, the tin atoms are five-coordinated in a distorted trigonal bipyramidal geometry. A one-dimensional linear polymer is formed through an interaction between the O atoms of pyridine-3-carboxylic acid N-oxide and tin atoms of an adjacent molecule.

Excess molar volume(V E) data on binary liquid mixtures of methylheptenone (MHO) with methanol, ethanol, n-propanol or n-butanol have been determined from the density measurements at 298.15 K and atmospheric pressure. The values of V E in all the systems over the entire composition range are quantified by the Redlich-Kister equation. The effects of the chain length of alkanols on V E are discussed.

Tripartite Arbitrary Two-Qutrit Quantum State Sharing

Communications in Theoretical Physics 2008年第5期49卷 1191-1194页

作者： YUAN hao LIU Yi-min han Lian-Fang ZhanG Zhan-Jun Key Laboratory of Optoelectronic Information Acquisition ＆= Manipulation of ministry of Education of Chinas School of Physics ＆= Material Science Anhui University Hefei 230039 China Department of Physics Shaoguan University Shaoguan 512005 China Department of Physics and Center for Quantum Information Science National Cheng Kung University Tainan 70101 Taiwan China

A tripartite scheme for securely sharing an arbitrary unknown two-qutrit state is proposed, where two generalized Greenberger-Horne-Zeilinger （GHZ） states serve as the quantum channel linking the three legitimate parties. The quantum information （i.e., the arbitrary unknown two-qutrit state） from the sender can be split in such a way that it can be reconstructed deterministically by any agent via a proper unitary operation provided that both agents collaborates together. Moreover, the generalization of the tripartite scheme to more-party case is also outlined.
