目的:探讨树突状细胞(DCs)所分泌的外泌体(DEXs)对心肌梗死(mi)后肝细胞血脂谱的影响及可能的作用机制。方法:用正常心肌细胞或梗死心肌细胞的上清液刺激小鼠DCs,将DCs分泌的DEXs分别命名为Control-DEX和mi-DEX。用两组DEXs处理肝细胞,... 详细信息

目的:探讨树突状细胞(DCs)所分泌的外泌体(DEXs)对心肌梗死(mi)后肝细胞血脂谱的影响及可能的作用机制。方法:用正常心肌细胞或梗死心肌细胞的上清液刺激小鼠DCs,将DCs分泌的DEXs分别命名为Control-DEX和mi-DEX。用两组DEXs处理肝细胞,酶标测量仪测定肝细胞中脂质的合成和分泌情况。进一步通过蛋白质印迹和实时荧光定量PCR检测肝细胞哺乳动物雷帕霉素靶蛋白(mTOR)-甾醇调节元件结合蛋白(SREBP)通路相关分子的表达。结果:mi-DEX干预肝细胞后,胆固醇和低密度脂蛋白胆固醇(LDL-C)水平显著升高,mTOR-SREBP通路相关分子表达量增加(Pmi-DEX可通过干扰肝细胞中的mTOR-SREBP途径,在mi后肝细胞的血脂代谢中发挥重要作用。

草地植被结构对于其生产和生态功能至关重要,但大尺度信息严重匮乏.本研究结合多源遥感数据和深度学习,在区域尺度上厘清了青藏高原高寒草地基于群系的植物群落结构空间格局,并比较了其历史变化.过去40年,高寒草甸在高寒草地中的比例从50%上升到69%,反映了变暖变湿的环境变化.此外,高寒草甸和高寒草原中高山嵩草草甸和紫花针茅草原的优势度分别增强到76%和92%.其中,气候因子驱动了紫花针茅草原近些年的分布;高山嵩草草甸近些年的分布则并非完全由气候驱动,人类活动可能起重要作用.本研究首次探索了区域尺度植被结构特征与历史变化,为认识青藏高原草地变化的驱动力及其空间异质性提供了新视角.
