Blocking growth factor stops rejection process
For the first time scientists have found that a growth factor called vascular endothelial growth factor receptor-3 (VEGFR-3), known to cause the growth of lymphatic vessels in the body, controls how immune cells traffic (move) within the eye and also stimulates the immune system to reject corneal transplants--the most common type of transplantation performed. The researchers from the Schepens Eye Research Institute and the Massachusetts Eye and Ear Infirmary, both affiliates of Harvard Medical School, have also found that when this growth factor is blocked, corneal transplants survive. The study, published in the August issue of Nature Medicine, is the first to make a link between VEGEFR-3 and the bodys immune response, and may hold significant promise not only for new treatments to prevent transplant rejection but also for diseases such as cancer that may proliferate because of VEGF-3.
"What we have discovered is a previously unknown connection or pathway that stimulates the immune response in the eye and in other parts of the body," says Reza Dana, MD, MPH, a Senior Scientist at the Schepens Eye Research Institute, an Associate Professor and corneal specialist at the Massachusetts Eye and Ear Infirmary and Harvard Medical School, and the senior author of the study.

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.
