| 1 | Current approaches to reduce or eliminate mitochondrial DNA mutations显示文摘Mitochondrial DNA(mt DNA)mutations have been implicated in a broad range of disorders which severely affect human health(Wallace,1999).Some drugs have been developed to slow down pathological changes of mitochondrial disorders.However,there is no effective treatment for patients with mt DNA mutations.mt DNA is less protected and has fewer repair mechanisms than nuclear DNA(n DNA).Such a reality results in a much higher | Liang Yang Tingfang Mei Xiaobing Lin Haite Tang Yi Wu Rui Wang Jinglei Liu Zahir Shah Xingguo Liu | 2016 | Science China(Life Sciences)2016，59，5： | 3 |
| 2 | GPR54 deficiency reduces the Treg population and aggravates experimental autoimmune encephalomyelitis in mice显示文摘GPR54 is highly expressed in the central nervous system and plays a crucial role in pubertal development. However, GRP54 is also expressed in the immune system, implying possible immunoregulatory functions. Here we investigated the role of GPR54 in T cell and immune tolerance. GPR54 deficiency led to an enlarged thymus, an increased number of thymocytes, and altered thymic micro-architecture starting around puberty, indicating GPR54 function in T-cell development through its regulatory effect on the gonadal system. However, flow cytometry revealed a significant reduction in the peripheral regulatory T cell population and a moderate decrease in CD4 single-positive thymocytes in prepubertal Gpr54^(-/-) mice. These phenotypes were confirmed in chimeric mice with GPR54 deficient bone marrow-derived cells. In addition, we found elevated T cell activation in peripheral and thymic T cells in Gpr54^(-/-) mice. When intact mice were immunized with myelin oligodendrocyte glycoprotein, a more severe experimental autoimmune encephalomyelitis(EAE) developed in the Gpr54^(-/-) mice. Interestingly, aggravated EAE disease was also manifested in castrated and bone marrow chimeric Gpr54^(-/-) mice compared to the respective wild-type control,suggesting a defect in self-tolerance resulting from GPR54 deletion through a mechanism that bypassed sex hormones. These findings demonstrate a novel role for GPR54 in regulating self-tolerant immunity in a sex hormone independent manner. | Roumei Xing Fang Liu Yiqing Yang Xueqin Cui Tongtong Wang Ling Xie Yongliang Zhao Lei Fang Tingfang Yi Biao Zheng Mingyao Liu Huaqing Chen | 2018 | Science China(Life Sciences)2018，61，6： | 1 |
| 3 | Advanced nano drug delivery systems for neuroprotection against ischemic stroke显示文摘Ischemic stroke(IS)represents a significant threat to brain health due to its elevated mortality and disability rates.The efficacy of small-molecule neuroprotective agents has been impeded by challenges associated with traversing the blood-brain barrier(BBB)and limited bioavailability.Conversely,advanced nano drug delivery systems hold promise for overcoming these obstacles by facilitating efficient transportation across the BBB and maintaining optimal drug concentrations.This review aims to explore advanced neuroprotective nano drug delivery systems as a means of effectively administering neuroprotective agents to the brain using pharmaceutical approaches in the treatment of IS.By examining these systems,researchers and clinicians can gain valuable insights and innovative concepts,illuminating the potential of advanced neuroprotective nano drug delivery systems.Leveraging these advancements can drive the progress of pioneering and efficacious therapeutic interventions for IS. | Chenchen Xie Jun Liao Ning Zhang Yuhan Sun Yi Li Liyan Xiong Yingnan Zhang Xiaoyan Liu Wei Su Heming Chen Ping Zeng Xiaoqing Zhang Ying Lu Tingfang Wang Chuan Zhang | 2024 | Chinese Chemical Letters2024，35，2： | 0 |
