Live Cell Imaging of YeastDaniel R. Rines, Dominik Thomann, Jonas F. Dorn, Paul Goodwin and Peter K. SorgerINTRODUCTIONThe development of cloning vectors for green fluorescent protein (GFP) and the simplicity of yeast reverse genetics allow straightforward labeling of yeast proteins in living cells. Budding and fission yeast are therefore attractive organisms in which to study dynamic cellular processes such as growt......阅读全文

Cell-Stem-Cell:揭示细胞炎症记忆机制

  当组织经历炎症时,它的细胞会记得。在炎症的高峰期,细胞将蛋白质固定在其遗传物质上,并将它们在最后斗争中所处的位置记下来。下次接触时,炎症记忆就会启动。这些细胞利用以前的经验来更有效地做出反应,即使是对它们以前从未遇到过的威胁也是如此。如果皮肤以前接触过刺激物,如毒素或病原体,它就会更快地愈合伤口
