Our intake of fats (fatty acids) has changed dramatically over the last thirty years. At the same time there has been an increase in inflammatory diseases in the western world – especially asthma, atherosclerosis, and autoimmune diseases such as rheumatoid arthritis.
“We have shown that a subset of white blood cells, called dendritic cells, which initiate immune responses, rely on the fatty acid binding molecule aP2 for their function. It is possible that different fatty acids or their total levels will affect aP2 function in dendritic cells, and hence affect immune responses,” explains Mackay.
Professor Mackay added: “What we want to do now is study whether it is the total levels of fats or the different types of fats that alter dendritic cell function, through their binding to aP2. We know that dietary changes can improve symptoms of rheumatoid arthritis and we believe that a ‘diet hypothesis’ may account for the dramatic changes in inflammatory diseases seen in the western world over the past 30 years -molecules such as aP2 may be one of the clues that will help explain this phenomenon.”
Over-activation of dendritic cells can trigger inflammatory diseases. This discovery reveals aP2 is key to that process. Fatty acid binding molecules, such as aP2, have already been identified as promising targets for the treatment of metabolic disorders such as type 2 diabetes and atherosclerosis. This new research suggests that medicines directed at aP2 would have great potential in inflammatory as well as metabolic diseases.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
