The immunogenicity of tumours and the development of new cancer medicines

Microsatellite-unstable cancers are characterised by a large number of mutations within short repetitive DNA sequence regions, and can form novel peptides that the human immune system recognises as neoantigens. These cancers represent a starting point for the development of vaccines to prevent them appearing at an early stage of development. Microsatellite instability is particularly frequent in colon and cervical cancers.

Christiane Opitz, scientist at the German Cancer Research Center, is being awarded this year's Ita Askonas Prize of the European Federation of Immunological Societies. Opitz has discovered how tumor cells use certain metabolites to protect themselves against the immune system. Her research findings may provide important clues for the development of new therapeutic concepts.

Scientists of the Translational Lung Research Center Heidelberg (TLRC) and the German Cancer Research Center (DKFZ) have discovered a new link between excessive airway mucus and chronic airway inflammation that is characteristic of cystic fibrosis and chronic obstructive pulmonary disease (COPD). The researchers showed that mucus in the airways reprograms certain cells of the immune system.

Macrophages interacting with cytomegaloviruses - 22/02/2022

Cytomegaloviruses subvert macrophage identity

Cytomegaloviruses are basically harmless. However, if they occur along with other pathogens, they can trigger serious diseases. They can manipulate our immune system and encourage resident defence cells to migrate. Researchers at the Centre for Chronic Immunodeficiency (CCI) at the Freiburg University Medical Centre have discovered which mechanisms underlie the behavioural changes in macrophages that make it easier for other pathogens to attack.

About 500000 people in Germany suffer from dilatative cardiomyopathy DCM. Viral infections are the major cause of this myocardial disease. Its molecular and cellular mechanisms are being investigated in a transregional SFB project at the University of Tübingen.

Development of food allergies

Allergic reactions to certain types of food can, in extreme cases, lead to life-threatening anaphylactic shock. People with peanut allergies are particularly at risk. Allergic reactions can also gradually develop into chronic intolerances such as coeliac disease, for example. The causes of food allergies nearly always originate in early childhood.

Recycling of bacterial cell wall constituents

Bacterial cells are focused on growth and proliferation. These processes are initiated by cellular enzymes that break up the cell wall material murein introduce new material and degrade material that is no longer needed. And all this in large amounts about 50 per cent of murein are degraded and newly formed turnover per cell generation. Dr. Christoph Mayer and his team from the University of Constance have shown that the cells carry out effective…

Sharks can sense a few drops of blood in water. In fact they are able to smell blood in dilutions of as little as one to 10 billion. Is it just sharks or piranhas that have such an acute sense of smell? The answer is no - all fish have a highly developed sense of smell.

Researchers are challenging a common model of immunology

Up to now, scientists have assumed that mast cells, a certain type of immune cells, play a central role in the development of autoimmune diseases such as rheumatoid arthritis and multiple sclerosis. Current studies conducted at the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) have now provided evidence to refute this assumption. Now it is only the mast cells’ central function in allergies that remains undisputed.

Manfred Kist – 25 years of fascination for a stomach bacterium

Helicobacter pylori is a genus of bacteria that inhabits the human stomach. The bacteria can cause duodenal and gastric ulcers and are also linked to the development of gastric cancer. Prof. Dr. Manfred Kist from the Freiburg University Medical Centre has spent around 25 years of his scientific career on investigating H. pylori a bent rod-shaped bacterium.

In a so-called inactivated or killed vaccine, the virus particles it contains are first rendered inactive by means of the toxic chemical formaldehyde. A better way of achieving this, however, is to irradiate the pathogens with low-energy electrons. Four Fraunhofer Institutes have now developed a new method of vaccine production based on this technique that is not only quicker but also guarantees a higher quality of product.

The road to individualized tumour vaccines

What are the typical cancer cell characteristics that our immune system is directed against? Using a new biochemical method, scientists from the Neurosurgery Department of the Heidelberg University Hospital and the German Cancer Research Centre (Deutsches Krebsforschungszentrum, DKFZ) are now able to answer this question for each individual patient. The method is expected to help identify new target structures for individualized tumour vaccines.

Michael Reth – Immunobiological discoveries that meet resistance

Dr Michael Reth professor at the Max Planck Institute of Immunobiology and the University of Freiburg and some of his colleagues have recently uncovered the mechanism that foreign substances use to activate B cells of the immune system. The researchers were using synthetic biology methods long before this particular branch of science existed in its present form. Their results require a paradigm change and a revision of the reference books.
