| 1 | Extracellular vesicle activities regulating macrophage- and tissue-mediated injury and repair responses显示文摘Macrophages are typically identified as classically activated(M1) macrophages and alternatively activated(M2) macrophages,which respectively exhibit pro-and anti-inflammatory phenotypes,and the balance between these two subtypes plays a critical role in the regulation of tissue inflammation,injury,and repair processes.Recent studies indicate that tissue cells and macrophages interact via the release of small extracellular vesicles(EVs) in processes where EVs released by stressed tissue cells can promote the activation and polarization of adjacent macrophages which can in turn release EVs and factors that can promote cell stress and tissue inflammation and injury and vice versa.This review discusses the roles of such EVs in resulating such interactions to influence tissue inflammation and injury in a number of acute and chronic inflammatory disease conditions,and the potential applications,advantage and concerns for using EV-based therapeutic approaches to treat such conditions,including their potential role of drug carriers for the treatment of infectious diseases. | Qian Hu Christopher J.Lyon Jesse K.Fletcher Wenfu Tang Meihua Wan Tony Y.Hu | 2021 | Acta Pharmaceutica Sinica B2021，11，6： | 22 |
| 2 | 血液中羟基化缓激肽作为肿瘤厌氧指标的研究显示文摘组织缺氧在消化系统、呼吸系统、肾脏疾病和癌症等多种疾病的发生发展中起到关键作用.然而,由于缺乏快速、准确和非侵入性的检测方法,评估组织缺氧情况和预测患者的预后结果仍然具有非常大的挑战性.本文假设血液中Hyp-BK/BK比率可以作为缺氧检测的标志物,以胰腺癌作为研究模型,通过监测Hyp-BK/BK比率可以预测组织缺氧水平以及抗肿瘤治疗的预后情况.研究表明,缺氧条件下肿瘤组织中高表达的P4HA1和治疗前患者血液样本中Hyp-BK/BK比率升高有关,并且两者都与患者预后不良相关.这些结果有力地表明血液中Hyp-BK/BK比率可以作为非侵入性的组织缺氧标志物,对胰腺癌的预后和治疗效果进行预测. | 刘洋 谷雅君 Serina Ng 邓载安 Christopher J.Lyon Eugene J.Koay 宁波 Matthew H.Katz Paul J.Chiao 范佳 韩海勇 Daniel Von Hoff 胡晔 | 2020 | Science Bulletin2020，65，18： | 2 |
| 3 | SARS-CoV-2 Epitopes following Infection and Vaccination Overlap Known Neutralizing Antibody Sites显示文摘Identification of epitopes targeted following virus infection or vaccination can guide vaccine design and development of therapeutic interventions targeting functional sites,but can be laborious.Herein,we employed peptide microarrays to map linear peptide epitopes(LPEs)recognized following SARS-CoV-2 infetion and vaccination.LPEs detected by nonhuman primate(NHP)and patient IgMs after SARS-CoV-2 infection extensively overlapped,localized to functionally important virus regions,and aligned with reported neutralizing antibody binding sies.Similar LPE overlap occurred atfter infection and vaccination,with LPE clusters specifc to each stimulus,where strong and conserved LPEs mapping to sites known or likely to inhibit spike protein function.Vaccine-specifc LPEs tended to map to sites known or likely to be afected by structural changes induced by the proline substitutions in the mRNA vaccine's S protein.Mapping LPEs to regions of known functional importance in this manner may acelerate vaccine evaluation and discovery of targets for sile secific therapeutic interventions. | Li Yang Te Liang Lane M.Pierson Hongye Wang Jesse K.Fletcher Shu Wang Duran Bao Lii Zhang Zhen Huang Wenshu Zheng Xiaomei Zhang Heewon Park Yuwen Li James E.Robinson Amy K.Fechan Christopher J.Lyon Jing Cao Lisa A.Morici Chenzhong Li Chad J.Roy Xiaobo Yu Tony Hu | 2022 | Research2022，，2： | 0 |
| 4 | Extracellular vesicles in the pathogenesis and treatment of acute lung injury显示文摘Acute lung injury(ALI)and acute respiratory distress syndrome(ARDS)are common life-threatening lung diseases associated with acute and severe inflammation.Both have high mortality rates,and despite decades of research on clinical ALI/ARDS,there are no effective therapeutic strategies.Disruption of alveolar-capillary barrier integrity or activation of inflammatory responses leads to lung inflammation and injury.Recently,studies on the role of extracellular vesicles(EVs)in regulating normal and pathophysiologic cell activities,including inflammation and injury responses,have attracted attention.Injured and dysfunctional cells often secrete EVs into serum or bronchoalveolar lavage fluid with altered cargoes,which can be used to diagnose and predict the development of ALI/ARDS.EVs secreted by mesenchymal stem cells can also attenuate inflammatory reactions associated with cell dysfunction and injury to preserve or restore cell function,and thereby promote cell proliferation and tissue regeneration.This review focuses on the roles of EVs in the pathogenesis of pulmonary inflammation,particularly ALI/ARDS. | Qian Hu Shu Zhang Yue Yang Jia‑Qi Yao Wen‑Fu Tang Christopher J.Lyon Tony Ye Hu Mei‑Hua Wan | 2023 | Military Medical Research2023，10，4： | 0 |
