CeMM Discovers Antiviral Protein

22.01.2009
The Center for Molecular Medicine of the Austrian Academy of Sciences (CeMM) announces the discovery of a new molecular sensor in human cells capable of recognizing infecting viruses and transmitting an alarm signal to the body.

The study, directed by the center’s director Giulio Superti-Furga, appears today in the online advanced publication route of the journal Nature Immunology. The newly discovered protein, termed AIM2, patrols the inside of human immune cells and when it encounters a DNA that is suspicious, possibly coming from an intruding virus or bacterium, triggers the secretion of the signaling protein Interleukin-1.

This proinflammatory molecule activates an anti-invasion alarm program throughout the entire body. It is one of the main causes of fever and a central mediator of autoimmune disease. Thus, the study identified a new centerpiece of the human’s defense arsenal against pathogens.

“We are excited about this molecule as it helps understand the body’s immediate reaction to infections. It is much too early to say, but in the future AIM2 could lead to ways to enhance the patients’ own protection when this is needed, as during epidemics or when otherwise immune depressed”, stresses Tilmann Bürckstümmer, the first author of the study.

The results derived from a large scale, systematic search for human proteins that bind pathogenic molecules. Three other groups from Worcester, Philadelphia and Adelaide report the identification of the same protein in parallel publications appearing in the journals Nature and Science. This fact stresses the importance of the discovery made at CeMM.

“I am very proud that our new research center could contribute to such a fundamental immunology finding. It shows that CeMM as an Austrian research organization competes in the top-league of international research only a few years after being founded and before entering its new building. We are eager to collaborate with our clinical partners at the Medical University of Vienna to investigate if malfunction of the protein may be associated with autoimmune disease, when too much inflammatory signals are produced”, adds Giulio Superti-Furga.

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Computer-assisted methods aid Heidelberg physicists in reproducing experiment with ultracold atoms

Two researchers at Heidelberg University have developed a model system that enables a better understanding of the processes in a quantum-physical experiment...

Im Focus: Glacier bacteria’s contribution to carbon cycling

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.

A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
