  • 1.Researchers then delved into the mechanism by which oxyphenbutazone kills TB and found that the conditions that allow the bacterium to remain dormant modify the drug to the point that it starts reacting against both non-replicating and replicating TB. "When this happens, TB can't defend itself and dies," Dr. Nathan says.

    随后研究者们开始探究oxyphenbutazone杀死结合杆菌的机理,他们发现:当oxyphenbutazone开始作用于未复制及正在复制的细菌时,结合杆菌便进入了休眠状态。“当这一切发生时,结核杆菌不能抵抗,于是就死亡了”,Dr. Nanthan说。

  • 2.To defend against foreign pathogens, plants and animals employ proteins known as immune sensors which recognize extracellular molecules and initiate immune response. Despite playing a critical in innate immunity, the underlying mechanisms governing this recognition process have remained elusive. Previous work by the team has shown that in plants, HSP90, a molecular chaperone, binds to the proteins SGT1 and RAR1 to form a complex which mediates the activity of immune sensors, but the dynamic nature of the complex has prevented a detailed understanding of its structure and role.

    为了抵御外来病原的入侵,植物和动物都拥有一些蛋白质被称作免疫传感器,它能识别细胞外的分子并且能够激发免疫反应。尽管这些蛋白质在先天性免疫中扮演重要角色,但是控制这些识别程序的潜在机制仍然不清楚。该团队先前的研究表明,在植物,HSP90,这种分子伴侣,与SGT1和RAR1结合形成一种络合物,能够调节免疫传感器的活性,但是这种络合物的动态性妨碍了对其结构和作用的细节性研究。

  • 5.The study highlights an amazing change that takes place in a mother's body when she begins producing breast milk. For years before her pregnancy,cells that produce antibodies against intestinal infections travel around her circulatory system as if it were a highway and regularly take an “off-ramp” to her intestine. There they stand ready to defend against infections such as cholera or rotavirus. But once she begins lactating, some of these same antibody-producing cells suddenly begin taking a different “off-ramp,” so to speak, that leads to the mammary glands. That way, when her baby nurses, the antibodies go straight to his intestine and offer protection while he builds up his own immunity.

    该研究强调了当母亲开始分泌乳汁时,母体正发生惊人的变化。孕前,抵御肠道感染的抗体生成细胞就像行使在高速公路上一样游走在母亲的循环系统,然后规律地离开循环系统留在肠道处,在那里他们随时准备这抵御比如霍乱或轮状病毒等感染。但是一旦母亲开始泌乳,一部分该种抗体生成细胞突然开始停留在不同的器官,即乳腺,这样当婴儿吸吮乳汁时,这些抗体直接进入婴儿肠道,在其建立起自己的免疫系统时提供保护。
