In the July 28 issue of the Journal of Biological Chemistry, Roman Dziarski, Ph.D., and Dipika Gupta, Ph.D., propose that the proteins might be used to develop medications that could boost the body's impaired day-to-day response to bacteria in HIV/AIDS patients and others with compromised immune responses. The scientists announced discovery of the protein called PGLYRP – peptidoglycan recognition proteins – earlier this year.
Patients, such as those with HIV/AIDS, are susceptible to bacterial infections that are easily averted by people with healthy immune systems but are life-threatening to people with impaired systems.
Drs. Dziarski and Gupta, in their latest report, revealed many parts of the body produce these proteins, which fight disease-causing bacteria. These proteins appear to be the front line in defending the body from infection, mounting a defense long before the body's main immune system responds.
The IU School of Medicine – Northwest scientists report that various organs mount different defensive responses with PGLYRP when exposed to bacteria. The skin produces these proteins only when exposed to virulent or high numbers of bacteria.
In contrast, the liver, whose function is to continuously monitor the blood and fight acute infection, produces PGLYRP constantly. The researchers suggest that the liver's constant protein production may help fulfill the organ's preventative role as a blood filter.

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.
