Legionella pneumophila temporally regulates the activity of ADP/ATP translocases by reversible ADP-ribosylation
Jiaqi Fu, Pengwei Li, Hongxin Guan, Dan Huang, Lei Song, Songying Ouyang, Zhao-Qing Luo
之前的研究发现，Legionella pneumophila的效应蛋白Ceg3通过对ADP/ATP转运酶进行腺苷二磷酸核糖基化修饰（ADP-ribosylation）来抑制宿主能量代谢。该文章揭示了这种抑制在受另一效应蛋白Larg1调节，它通过去ADPR修饰在感染后期使底物恢复活性。

Jin Yang, Jessica T. Barra, Danny K. Fung, Jue D. Wang
该研究团队发现革兰氏阳性菌对于抑菌性抗生素需要产生严谨反应（stringent response）才可以存活，并且揭示了严谨反应核苷酸信号(p)ppGpp介导的抗生素杀菌（bactericidal）—抑菌作用（bacteriostatic）转变的机理， 从而有助于开发针对细菌核苷酸信号的抗菌疗法。

The secretory Candida effector Sce1 licenses fungal virulence by masking the immunogenic β‐1,3‐glucan and promoting apoptosis of the host cells
Hongyu Wu, Li Wang, Wenjuan Wang, Zhugui Shao, Xin-Ming Jia, Hui Xiao, Jiangye Chen
该研究团队基于真菌学和免疫学技术开展了真菌和宿主的相互作用的研究，发现了白念珠菌中一个新的分泌型效应因子Sce1，该效应因子能够在酸性、营养缺乏或厚壁孢子培养条件下高表达。在正常条件下，Sce1定位于细胞壁并能够掩盖β-(1,3)-葡聚糖的免疫激活功能。当白念珠菌被免疫细胞吞噬后，Sce1能够从细胞壁上释放并造成免疫细胞死亡，从而从两方面达到免疫逃逸的效果，该研究为理解白念珠菌和宿主相互作用机制提供了新的思路。
