New discovery paves the way for new diagnosis of serious lung disease

03.03.2009
The discovery by Uppsala University researchers of a previously unknown protein in the cells of the lower air ways brings new potential for early diagnosis of a serious lung disease. The findings, published today in the Web edition of the American journal Proceedings of the National Academy of Sciences, can also provide new knowledge of the cause of common diseases like asthma and chronic bronchitis.

Researchers at Uppsala University and Uppsala University Hospital have identified a protein in the lungs that is important to the immune defense system in an autoimmune lung disorder that is not seldom fatal. The newly discovered protein, called KCNRG, occurs in cells in the lower air ways found on the surface of the bronchia.

This observation enables researchers to study more closely the first phase of the autoimmune disease, that is, when the immune system erroneously attacks the body's own tissues instead of attacking foreign organisms like bacteria or viruses. The discovery also provides new avenues for developing new diagnostic methods.

The researchers used an unusual hereditary autoimmune disorder, autoimmune polyendocrine syndrome type 1 (APS-1), as a model. Patients with this disease are afflicted by the immune system erroneously attacking several tissues, such as the liver, insulin-producing cells, and adrenal glands.

"Only now have we understood that the lungs are attacked as well and that in many cases this is the most serious component of the disease APS-1," says Dr. Mohammad Alimohammadi.

"It's our hope that the discovery of the protein that the immune system targets, besides making early diagnosis possible, will also be possible to use in understanding the mechanism behind the occurrence of common public health disorders like asthma and chronic bronchitis."

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
