1 Science - Research Articles

  1. Apical stress fibers enable a scaling between cell mechanical response and area in epithelial tissue 细胞是如何控制自身大小,顶端压力纤维 aSF定位在紧密连接处,其数量与细胞顶端区域成正比,aSF 反过来又能调控 Hippo 通路
  2. Behavioral state coding by molecularly defined paraventricular hypothalamic cell type ensembles 体内对同一个单细胞进行钙成像和 RNA-seq,发现marker gene组合能预测神经元反应
  3. The nucleus measures shape changes for cellular proprioception to control dynamic cell behavior 细胞核能起到感应细胞自身大小的功能,细胞核被拉伸时,内核膜 unfold,用钙信号控制 actomyosin 收缩和迁移粘性
  4. The nucleus acts as a ruler tailoring cell responses to spatial constraints 与上一篇同一工作,细胞核作为 ruler 感应周围空间限制,上调收缩性,介导细胞迁移。展示了细胞如何通过狭窄通道 restrictive pore,与癌细胞扩散,免疫反应,胚胎发育都有关。
  5. Mammalian lipid droplets are innate immune hubs integrating cell metabolism and host defense 脂质体参与哺乳动物先天免疫,在LPS诱导下,既组织免疫蛋白杀死病原体,调节代谢来适应感染。
  6. Microbiota-modulated CART+ enteric neurons autonomously regulate blood glucose 回肠和结肠的神经元比十二指肠的对微生物更敏感,其中 CART+ 神经元轴突下游调控血糖,这一过程看起来不用中枢参与。
  7. Patterning and growth control in vivo by an engineered GFP gradient GFP和抗GFP的纳米小体可以形成浓度梯度,把后者连接到天然形态发生素Dpp的受体,然后GFP就可以控制形态发生。加上GPI之后几乎和野生型一样,但没有明确为什么需要 GPI。

  9. Structural and mechanistic bases for a potent HIV-1 capsid inhibitor GS-6207 为什么能抗 HIV-1 呢?同时结合两个衣壳亚基,不让他们解离;同时抑制与胞内辅因子的结合。
  10. Comprehensive quantification of fuel use by the failing and nonfailing human heart 分析了心脏靠哪些代谢物供能。很多结论。心脏主要消耗氨基酸而不是葡萄糖,受损的心脏消耗更多的酮体和乳酸。
