Atherosclerosis: Three steps away from a vaccine

19.09.2007
Overcoming a bottleneck will make the vaccine ready for clinical trials, say scientists on the first day of the Annual EVGN Meeting

The Fourth Annual Meeting of the European Vascular Genomics Network (EVGN, www.evgn.org), Network of excellence on cardiovascular disease, opened yesterday, September 17th, in the prestigious venue of the University of Bristol (UK), that made available to the event two historical buildings: the Wills Memorial Building, inaugurated by King George V and Queen Mary, and the Merchant Venturers Building.

Run jointly with the European Vascular Biology Organization (EVBO) and the British Atherosclerosis Society and articulated over a three day period (September 17-20), the EVGN Meeting will take place in parallel with the 4th European Meeting on Vascular Biology and Medicine (EMVBM), gathering more than 400 scientists from all over Europe with representatives from the rest of the world. Cardiologists and diabetes researchers, as well as hematologists, thrombosis scientists, gene therapists and oncologists will alternate their presentations to show new data and debate perspectives on the therapeutic side.

“Once again as we did in 2005 – said the President of EVBO Professor Andrew Newby – the simultaneous presence of renowned scientists with different expertise and competence is a unique chance to confront news and views on controversial aspects of vascular disease, an elusive but deadly disease, and to enhance the productivity and the competitiveness of the European scientific community at large”.

The agenda is more than full: 10 plenary speakers, a selection of 45 oral presentations and almost 200 posters complete a rich and comprehensive programme. And tomorrow, Sept. 19, the Young Investigator Award will be assigned to a young distinguished researcher, with the aim of encouraging his/her investigations in years to come.

The opening Hugh Sinclair lecture that concluded the first day of the Meeting was presented by Professor Goran K. Hansson, from the Karolinska Hospital, Center for Molecular Medicine, who offered an elegant state-of-the-art summary of atherosclerosis, with an eye to the most appealing therapeutic perspective: a vaccine against this immune disease. “The current knowledge of atherosclerosis has markedly changed over the latest years” said Hansson, who is a leading scientists in the immunology field. “Today we know that atherosclerosis is an inflammatory disease with both a systemic association and a genetic involvement. Inside the plaques there is a strong immune activity, and day after day we learn more and more about the immunopathogenetic mechanisms with the aid of mouse models that mimic the disease in humans. But we are still a few steps away from a human trial”. There are three unresolved issues. We need: to find the proper antigen for immunization (a good candidate is the LDL particle, Low Density Lipoprotein or bad cholesterol); to clarify the mechanism of action (it has to be decided whether the vaccine wants to reduce bad circulating lipoproteins or act upon immune cells that create inflammation in the artery); finally, we have to identify the optimal administration route. “When we overcome these bottlenecks, we will get to the vaccine.”

Today, September 18th, the EVGN scientists will address some of the most critical topics for cardiovascular disease:

• strategies to modulate angiogenesis (the growth of blood vessels which is necessary to avoid tissue necrosis after ischemia);

• ways to target atherosclerotic plaques;

• the clinical experience in the acute myocardial infarction

“Most of the convened scientists – commented Professor Newby – are at the fore front of the research. We expect interesting news from this fourth EVGN Meeting. We also want to start proceeding on new therapeutic avenues, to improve scientists’ interactions and encourage young talents”.

The European Vascular Genomics Network (EVGN) is the first Network of Excellence on cardiovascular disease funded by the European Commission under the 6th Framework Programme "Life sciences, genomics and biotechnology for health" (Contract Number: LSHM-CT-2003-503254).

The conference is supported by an unrestricted educational grant from Laboratoires SERVIER.

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...
