  • 1.The researchers describe this defence mechanism as a trade-off, where the bodyfights one enemy but exposes itself to the other. This was demonstrated intheir study exploring the connection between malaria and non-typhoid salmonella(NTS)- an infection which is particularly dangerous for children.

  • 2.Scientists have been working on developing retina prostheses for more than twenty years now. Research has been conducted particularly intensively in Germany, where scientists and patients have worked in tandem and have succeeded in obtaining government funding. “Back then we didn't want high-tech just for space and defence programs but finally high-tech for people as well,” Professor Rolf Eckmiller, a neuro-informatics specialist at the University of Bonn and a pioneer in the field, recalls.

    科学家在开发视网膜假体上已花费了超过20年时间。该研究在德国开展的尤为积极,在科学家和患者共同努力下,并成功获得政府资助。Rolf Eckmiller是来自Bonn大学的一名神经信息学专家,也是该领域的先驱者,他回忆说:那时我们没有仅仅想要拥有太空和防卫项目的高新技术,而是也想拥有服务人类的高新技术。

  • 3.Plectasin belongs to the class of defensins. These defence molecules are commonly found in fungi, animals, as well as plants.

  • 4.Thanks to the work of the three Laureates it is now possible to understand at molecular level how the cell controls a number of central processes by breaking down certain proteins and not others. Examples of processes governed by ubiquitin-mediated protein degradation are cell division, DNA repair, quality control of newly-produced proteins, and important parts of the immune defence. When the degradation does not work correctly, we fall ill. Cervical cancer and cystic fibrosis are two examples. Knowledge of ubiquitin-mediated protein degradation offers an opportunity to develop drugs against these diseases and others.

  • 5.When a normal virus such as the common cold infects people we develop an immune response and produce defence cells which can quickly get rid of the virus. But when HIV infects us it can last for our whole life. HIV does this by successfully hiding from our immune cells, which are seeking to identify and destroy the virus, fooling them into thinking that it is part of the normal trash in a cell rather than being clearly visible on the cell surface.
