研究人员使用CD8 + T细胞没有任何1型干扰素受体的小鼠探索工作机制是如何运作的,以及缺乏1型干扰素的CD8 + T细胞是如何耗尽NK细胞的。如果没有自然杀手的存在,尽管缺乏干扰素检测,但T细胞依然会增多,成熟和发育。此外,瑞士苏黎世联邦理工学院的免疫生物学家发现,这些无需传感器的T细胞逐渐形成其表面的“识别标签”,一旦与NK细胞接触,就会引发NK细胞的杀伤作用。因此,这些“应激标签”的表达通过干扰素结合以及通过T细胞上的干扰素受体发出信号被抑制。如果由于受体的缺乏而阻止了信号的传输,那么细胞会大量表达这些应激分子。
自身免疫性疾病的机制?
到目前为止,尚不清楚人类是否具有相同的机制。然而,人类免疫系统用来保护T细胞避免NK细胞攻击的基本过程很可能是类似的。在一方面,研究人员现在揭示应激T细胞需要保护自己免受NK细胞攻击的机制。另一方面,这项发现形成了新的假设。例如,可以想到的是,缺乏干扰素受体的T细胞活化显示出它们为“应激的”,并因此杀死了。自身免疫反应性T细胞的活化过程中可能会出现这样的情况,例如,它通常发生在不存在高浓度的1型干扰素。Oxenius和她的团队有很浓厚的兴趣将在未来几年内测试这些令人兴奋的假设。
加州大学圣地亚哥分校的生物学家发现能够使动物细胞产生核糖体的化学系统中的‘未知环节’——每个细胞中含有数千蛋白‘工厂’加工所有建立组织和维持生命所必须的蛋白。他们的发现不仅强迫分子生物学基础教科书的修订,而且也为科学家提供较好的理解如何限制自由的细胞生长,如癌症,也许通过控制核糖体的输出来调节。这一研究发现发表在6月23日的《Genes & Development》期刊上。核糖体对于品种多样蛋白的产生具有重要责任;包括酶;结构分子如毛发、皮肤和骨骼;激素类如胰岛素;以及我们免疫系统的组分如抗体。视为生命zui重要的分子机制,核糖体已被科学家广泛研究(如,2009年的化学诺贝尔奖就颁发给核糖体结构和功能的研究)。但是直到现在研究人员并没有*了解用于组成核糖体的蛋白质是如何自我产生的全部细节。
在多细胞动物中,如人类,核糖体由大约80种不同蛋白组成的(人类有79种,而其他动物有一些数量差异)与四种不同的RNA分子一样。1969年,科学家们发现核糖体RNAs的合成是由专门的系统利用两种酶:RNA聚合酶 I 和RNA聚合酶III执行的。但是直到现在,科学家们仍然不确定是否有一个互补系统也负责为装配成核糖体的80种蛋白的生产。
“我们发现核糖体蛋白的合成经过一种新奇的调节系统与RNA聚合酶II和一种称为TRF2的因子,” Kadonaga 说。“对于多数蛋白质的产生,RNA聚合酶II的功能与称为TBP的因子,但对于核糖体蛋白质的合成,它使用TRF2。”

Researchers using mice that did not have any Type 1 interferon receptor on CD8 + T cells explored how the working mechanism works and how NK cells are depleted by CD8 + T cells lacking type 1 interferon. Without the existence of a natural killer, T-cells will continue to proliferate, mature, and develop despite the lack of interferon testing. In addition, immune biologists at the Federal Institute of Technology in Zurich, Switzerland, found that these sensorless T cells evolved to form "labels" on their surface that, when contacted with NK cells, elicited NK cell killing. Thus, the expression of these "stress tags" is inhibited by interferon binding as well as signaling by interferon receptors on T cells. If signaling is blocked because of lack of receptors, the cells express large quantities of these stressors.
Mechanisms of autoimmune diseases?
So far, it is unclear whether human beings have the same mechanism. However, the basic process that the human immune system uses to protect T cells from NK cell challenge is likely to be similar. On the one hand, researchers now reveal that stressed T cells need a mechanism to protect themselves from attack by NK cells. On the other hand, this finding has led to new assumptions. For example, it is conceivable that T cell activation, which lacks interferon receptors, shows that they are "stressed" and therefore killed. This may occur during the activation of autoimmune reactive T cells, for example, it typically occurs in the absence of high concentrations of type 1 interferons. Oxenius and her team are very interested in testing these exciting assumptions in the coming years.
Biologists at the University of California, San Diego discovered the 'unknown' part of the chemical system that produces ribosomes in animal cells - thousands of proteins in each cell. The 'factory' processes all the proteins necessary to build and sustain life. Their findings not only force the revision of basic textbooks in molecular biology, but also provide scientists with a better understanding of how to limit free cell growth, such as cancer, perhaps by controlling ribosomal output. The study was published in the June 23 issue of Genes & Development. Ribosomes have an important responsibility for the production of a diverse range of proteins; enzymes; structural molecules such as hair, skin and bone; hormones such as insulin; and components of our immune system such as antibodies. Considered the most important molecular mechanism of life, ribosomes have been extensively studied by scientists (eg, the 2009 Nobel Prize in Chemistry for the study of ribosomal structure and function). But until now researchers did not fully understand all the details of how the proteins used to make ribosomes are produced by themselves.
In multicellular animals, such as humans, the ribosome consists of about 80 different proteins (79 in humans and some in other animals), like the four different RNA molecules. In 1969, scientists found that the synthesis of ribosomal RNAs was performed by specialized systems using two enzymes, RNA polymerase I and RNA polymerase III. But until now, scientists are still not sure if there is a complementary system that is responsible for the production of 80 proteins assembled into ribosomes.
"We found that the synthesis of ribosomal proteins goes through a novel regulatory system with RNA polymerase II and a factor called TRF2," Kadonaga said. "For most protein production, RNA polymerase II functions with a factor called TBP, but for ribosomal protein synthesis, it uses TRF2."
A study released by ICE / endO 2014 in Chicago shows that ambient temperature can affect the body's production of brown fat: cool environment stimulates growth and warm conditions are counter-productive.
