| 1 | Plasmacytoid dendritic cells promote acute kidney injury by producing interferon-α显示文摘Acute kidney injury(AKI)is a common clinical complication associated with high mortality in patients.Immune cells and cytokines have recently been described to play essential roles in AKI pathogenesis.Plasmacytoid dendritic cells(pDCs)are a unique DC subset that specializes in type Ⅰ interferon(IFN)production.Here,we showed that pDCs rapidly infiltrated the kidney in response to AKI and contributed to kidney damage by producing IFN-α.Deletion of pDCs using DTR^(BDCA2) transgenic(Tg)mice suppressed cisplatin-induced AKI,accompanied by marked reductions in proinflammatory cytokine production,immune cell infiltration and apoptosis in the kidney.In contrast,adoptive transfer of pDCs during AKI exacerbated kidney damage.We further identified IFN-α as the key factor that mediated the functions of pDCs during AKI,as IFN-α neutralization significantly attenuated kidney injury.Furthermore,IFN-α produced by pDCs directly induced the apoptosis of renal tubular epithelial cells(TECs)in vitro.In addition,our data demonstrated that apoptotic TECs induced the activation of pDCs,which was inhibited in the presence of an apoptosis inhibitor.Furthermore,similar deleterious effects of pDCs were observed in an ischemia reperfusion(IR)-induced AKI model.Clinically,increased expression of IFN-α in kidney biopsies was observed in kidney transplants with AKI.Taken together,the results of our study reveal that pDCs play a detrimental role in AKI via IFN-α. | Bo Deng Yuli Lin Yusheng Chen Shuai Ma Qian Cai Wenji Wang Bingji Li Tingyan Liu Peihui Zhou Rui He Feng Ding | 2021 | Cellular & Molecular Immunology2021，18，1： | 1 |
| 2 | Therapeutic potential of C1632 by inhibition of SARS-CoV-2 replication and viral-induced inflammation through upregulating let-7显示文摘Dear Editor,The COVID-19 pandemic caused by SARS-CoV-2 has led to acute respiratory distress syndrome(ARDS)with a high rate of death.An excessive inflammatory response,caused by virus infection,is associated with severe clinical manifestations that may lead to death of patients.1 Therefore,the blockage of virus replication and suppression of hyper-inflammatory response are beneficial for COVID-19 treatment.However,the drug targeting both virus and hyper-inflammation,as far as we know,is not available yet. | Chen Xie Yanlian Chen Dongling Luo Zhen Zhuang Heping Jin Haoxian Zhou Xiaocui Li Haijun Lin Xiaohui Zheng Jing Zhang Peihui Wang Jincun Zhao Yong Zhao Hui Huang | 2021 | Signal Transduction and Targeted Therapy2021，6，3： | 1 |
| 3 | New insights into immune cell diversity in acute kidney injury显示文摘Acute kidney injury(AKI)is a frequent complication affecting hospitalized patients in medical wards and usually arises from ischemia‒reperfusion injury(IRI),sepsis,and nephrotoxic drugs.Excess infiltration and activation of immune cells in the kidney induce a continuous inflammatory response,which is characterized by substantial cytotoxicity that ultimately exacerbates kidney damage[1].The role of individual immune cell types in AKI has been mostly investigated in previous years.However,despite the successful results in experimental studies,treatments targeting a broad immune response have yielded minor improvements in patient outcomes,in part due to the imprecise understanding of immune cell heterogeneity.Recently,the focus of AKI research has shifted toward gaining insight into the heterogeneity and dynamic changes in immune cells with novel experimental approaches such as single-cell analysis,thereby redefining AKI pathophysiology. | Bo Deng Sutian Wang Peihui Zhou Feng Ding | 2023 | Cellular & Molecular Immunology2023，20，6： | 0 |
| 4 | A CD44-biosensor for evaluating metastatic potential of breast cancer cells based on quartz crystal microbalance显示文摘A sensitive CD44-biosensor based on quartz crystal microbalance(QCM) was proposed for evaluating metastatic potential of breast cancer cells by using hyaluronan(HA) functionalized substrate film,polydopamine and polyethyleneimine composite film,for the purpose of capturing CD44-positive cancer cells through specific binding of HA to CD44.Two differently CD44-expressed breast cancer cell lines(MDAMB-231 cells and MCF-7 cells) were put to use as targets for quantitative analysis as well as evaluation of metastatic potential of the cells.The limit of detection for MDA-MB-231(M231) cells and MCF-7 cells were 300 and 1,000 cells mL ~1 respectively.The expression level of CD44 on M231 cells exhibited two times higher than that of MCF-7 cells,indicating of a higher metastatic potential.Moreover,poly-Llysine modified QCM sensor was applied to monitor the stiffness of breast cancer cells that can reflect metastatic potential of cells.The results revealed that the MCF-7 cells were stiffer than M231 cells,implying that the M231 cells possessed higher metastatic potential.The proposed protocol is simple and rapid to evaluate the metastatic potential of cancer cells,in addition to offering a promising diagnostic tool for metastatic cancer. | Xiaojuan Yang Rongcheng Zhou Yan Hao Peihui Yang | 2017 | Science Bulletin2017，62，13： | 0 |
| 5 | Technologies of enhancing oil recovery by chemical flooding in Daqing Oilfield, NE China显示文摘By tracking and analyzing the research and practices of chemical flooding carried out in the Daqing Oilfield, NE China since the 1970 s, the chemical flooding theory, technology adaptability and existing problems were systematically summarized, and directions and ideas of development in the future were proposed. In enhanced oil recovery by chemical flooding, the Daqing Oilfield developed theories related to compatibility between crude oil and surfactant that may form ultra-low interfacial tensions with low-acidity oil, and a series of surfactant products were developed independently. The key technologies for chemical flooding such as injection parameter optimization and numerical simulation were established. The technologies of separation injection, cleansing and anti-scaling, preparation and injection, and produced liquid processing were developed. The matching technologies of production engineering and surface facilities were formed. Through implementation of chemical flooding, the Daqing Oilfield achieved outstanding performances with enhanced recovery rate of 12% in polymer flooding and with enhanced recovery rate of 18% in ASP flooding. To further enhance the oil recovery of chemical flooding, three aspects need to be studied:(1) fine characterization of reservoirs;(2) smart and efficient recovery enhancement technologies;(3) environment friendly, high-efficiency and smart matching processes. | SUN Longde WU Xiaolin ZHOU Wanfu LI Xuejun HAN Peihui | 2018 | Petroleum Exploration and Development2018，45，4： | 0 |
