Borrelia infection from a tick bite just as possible in a city centre park

03.02.2003


The chances of getting a Borrelia infection from a tick bite are no different in a city centre park than they are out in the archipelago. This is one of the recent discoveries of Professor Matti Viljanen and his research team who are looking into how the Borrelia bacteria deceives and manipulates the human immune defence system. The research project under the supervision of Professor Viljanen is part of the Academy of Finland’s Microbes and Man Research Programme.



One in three ticks in the parks in Helsinki, Finland, carry the Borrelia bacteria. Professor Viljanen and his team have also shown that ticks and Borrelia can be transmitted across continents in migratory birds. In birds, the Borrelia bacteria may cause an asymptomatic latent infection. During migration, variations in the bird’s hormone levels will activate the bacteria and cause it to grow in the bird’s blood. This will ensure that the bacteria is transmitted into the ticks living off the bird and improve its prospects of conquering new territory.

The Borrelia bacteria can deceive and manipulate the immune defence system in various different ways. It can mask itself using human proteins and in this way avoid the attacks of the white blood cells that are responsible for first-phase defence. It is also capable of altering the balance of the immune response to its own advantage.


The project is interested to know how the Borrelia bacteria deceives and manipulates the immune defence system at different stages. A further concern is with the question of how the bacteria advances in tissue and how it penetrates the walls of blood vessels. One area of special interest is the activation of a latent infection. The researchers will also be trying to find drugs that can help to restore the balance of the immune system and to cure chronic, rheumatic symptoms. The new information generated will help to produce more effective means for the prevention and treatment of Borrelia infections.

Professor Viljanen from Turku University, Finland, shares responsibility for running the programme with Professor Sven Bergström from Umeå University, Sweden: the Microbes and Man Research Programme is a joint Finnish-Swedish venture

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

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...

Im Focus: Giant Magnetic Fields in the Universe

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...

Im Focus: Tracing down linear ubiquitination

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...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

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.
