Molecule against psoriasis

23.11.2006
A number of chronic diseases break out because the body attacks an imaginary enemy. A research group at the Norwegian University of Science and Technology (NTNU) has created a molecule that prevents our immune system from running wild.

When the body thinks it is under attack, it defends itself in the best way possible, for instance by starting a defence inflammation.

This reaction is highly appropriate if the enemy is an influenza virus or something else that actually needs to be fought. However, sometimes the body misinterprets the signals, and starts a defence inflammation against a non-existent enemy.

The result could be so-called autoimmune diseases: psoriasis, arthritis, Bechterew’s, asthma, allergies, ulcerative colitis, multiple sclerosis, Crohn’s disease – and numerous others.

The list is longer than we care to imagine, and affects large parts of the population.

“Judas enzyme” sends the wrong message

Professor Berit Johansen at the Department of Biology at NTNU previously discovered which enzyme that misinterprets signals and reprograms cells to divide much faster than they should – thus provoking disease.

The enzyme is called phospholipase A2, less formally known as the “Judas enzyme”.

Now, Professor Johansen and her research group have created various stop molecules that prevent the “Judas enzyme” from sending the wrong messages to the cell nucleus. By doing so, the inflammatory reaction can be prevented.

One of these stop molecules was recently tested in mice infected with psoriasis. The results are more than promising: Every single mouse got better, in all respects.

In addition, it turned out that a high dosage yielded better effect than a low dosage.

Medical testing right around the corner

This discovery means that a substantial part of the road to a new type of medication is history. The next step is testing on humans.

Early next year, the substance will be available as a cream, ready to be applied on the first test persons. This testing will take place in France.

Professor Berit Johansen’s new firm, Avexxin, is also testing out two other molecules, one against rheumatoid arthritis, and one against nephritis.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

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...
