| 1 | 肌萎缩性侧索硬化蛋白激活小胶质细胞NLRP3炎性小体显示文摘小胶质细胞NLRP3炎性小体激活正在成为神经退行性变过程中神经炎症的关键因素。诸如β-淀粉样蛋白和α-突触核蛋白之类的致病性蛋白质聚集体触发小胶质NLRP3激活,从而导致半胱天冬酶-1激活和IL-1β的分泌。在小鼠肌萎缩性侧索硬化症(ALS)的SOD1G93A模型中,半胱天冬酶-1和IL-1β均促进疾病进展,提示小胶质NLRP3在该进程中发挥作用。然而先前的研究表明,SOD1G93A小鼠小胶质细胞不表达NLRP3,SOD1G93A蛋白在小胶质细胞中产生独立于NLRP3的IL-1β。本研究论证了使用Nlrp3-GFP基因敲入小鼠,在SOD1G93A小鼠中小胶质细胞表达NLRP3。本研究显示聚集和可溶性SOD1G93A均可激活小鼠原代小胶质细胞中的炎性小体,导致半胱天冬酶-1和IL-1β裂解,ASC斑点形成以及呈剂量和时间依赖性的IL-1β分泌。重要的是,SOD1G93A无法从缺乏Nlrp3的小胶质细胞或者用特异性NLRP3抑制剂MCC950预处理的小胶质细胞中诱导IL-1β分泌,从而证实NLRP3是介导SOD1诱导的小胶质细胞IL-1β分泌的关键炎症小体复合物。在TDP-43Q331K ALS小鼠模型中也观察到小胶质NLRP3上调,TDP-43野生型和突变蛋白亦可以NLRP3依赖性的方式激活小胶质炎性小体。从机制上讲,本研究确定了活性氧簇和ATP的生成是SOD1G93A介导的NLRP3激活所需的关键事件。总之,本研究的数据表明ALS小胶质细胞表达NLRP3,而病理ALS蛋白激活小胶质NLRP3炎性小体。因此,NLRP3抑制可能是阻止小胶质细胞神经炎症和ALS疾病进展的潜在治疗方法。 | Vandana Deora John D Lee Eduardo AAlbornoz Luke McAlary Cyril J Jagaraj Avril A B Robertson Julie D Atkin Matthew A Cooper Kate Schroder Justin J Yerbury Richard Gordon Trent MWoodruff 杜一星(编译) | 2020 | 神经损伤与功能重建2020,15,9: | 13 |
| 2 | NEAT1-TFE3和KAT6A-TFE3肾细胞癌:MiT家族易位性肾细胞癌中的新成员显示文摘小眼畸型相关转录因子(MiT)家族易位性肾细胞癌涉及TFE3或TFEB基因在内不同的基因融合。 据报道,TFE3的5′端可有多种融合基因伴侣,包括ASPSCR1、CLTC、DVL2、LUC7L3、KHSRP、PRCC、PARP14、NONO、SFPQ1、MED15以及RBM10。 通过免疫组化染色可以检测到这些融合基因激活TFE3转录。作者采用靶向RNA测序技术,鉴定了5例TFE3免疫组化染色阳性肾细胞癌的TFE3融合基因伴侣。3例为已知的基因融合,分别为ASPSCR1-TFE3、MED15-TFE3和RBM10-TFE3。2例为尚未报道的NEAT1-TFE3和KAT6A-TFE3基因融合。 | Pei J Cooper H Flieder D B 魏建国(摘译) 袁晓露(审校) | 2019 | 临床与实验病理学杂志2019,35,8: | 10 |

Relations of arterial stiffness with postural change in mean arterial pressure in middle-aged adults:the Framingham heart study. Hyperten- sion,2017,69(4) :685-690.站立位血压稳定调节受损可导致不良结果,包括跌倒、晕厥和定向障碍。平均动脉压(meanarterialpressure,MAP)通常在站立位时增加,然而,站立位MAP增加不足或减少可能导致脑灌注减少。已有研究报道,在动脉硬度增加的老年人中存在体位性低血压,年轻至中年人MAP的体位性改变与动脉硬度的相关性尚未阐明。该研究分析了Framingham心脏研究第3代队列中的受试者3205人(女性1693人,占53%)的直立性血压反应和全面血液动力学数据。 | Torjesen A Cooper LL Rong J Larson MG Hamburg NM Levy D Benjamin EJ Vasan RS Mitchell GF 刘莉 叶鹏 | 2017 | 中华高血压杂志2017,25,3: | 5 |
