【迪拜测试"空中出租车" 外观就像一个大号无人机】Dubai has showcased a flight for what it said would soon be the world's first drone taxi service under an ambitious plan to lead the Arab world in innovation.
The flying taxi developed by German drone firm Volocopter resembles a small, two-seater helicopter cabin topped by a wide hoop studded with 18 propellers.
It was unmanned for its test flight Monday. (China Daily)

Hepatology：#HCV通过巨噬细胞激活肝星状细胞介导CCL5分泌#
通过检测前炎症细胞因子中炎症及纤维化相关的基因，发现炎症标记物（NLRP3， IL-1β， IL-6 and CCL5）和前纤维生成的标记物（TGFβ1， COL4A1， MMP2 and α-SMA）表达均上升。进一步研究发现，暴露HCV下的巨噬细胞分泌的CCL5激活肝星状细胞炎症小体及纤维化标记物，CCL5中和抗体可移植星状细胞激活。研究结果证实暴露HCV的人巨噬细胞可介导CCL5分泌，在感染炎症和纤维化中发挥显着作用。
