  • Macrophages interacting with cytomegaloviruses - 22/02/2022 Graphik_CMV_Makrophagen_Teaser.jpg

    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.

    Cystic fibrosis & COPD: Mucus reprograms immune cells and promotes airway inflammation

    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.

    Award-winning science: Cancer-promoting metabolic pathways as targets of new therapies

    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.

    Newly discovered substances activate the inflammasome in macrophages

    Low-grade chronic inflammation caused by components of the innate immune system may increase the risk of developing a variety of diseases in the long term. In their search for the signalling mechanisms underlying these inflammatory processes, Prof. Dr. Olaf Groß' research group at the Freiburg University Medical Centre discovered new active substances with immunostimulatory properties that may open up additional possibilities in cancer…

  • Intestinal peptide heals lung - 14/10/2020 Die Immuntherapie (ICI)  aktiviert Effektor-T-Zellen  und reduziert auf der anderen Seite regulatorische T-zellen, um den Tumor zu besiegen (schwarze Zellen). Die durch die Immuntherapie ausgelöste Lungenentzündung wird mit Steroidtherapie (Cortison) oder mit inhaliertem VIP (vasoaktives intestinales Peptid) behandelt. Unter VIP kommt es zur Dämpfung der Entzündung.

    Inhalation of intestinal hormone VIP helps against immunotherapy-induced pneumonia

    If cancer patients develop pneumonitis, an inflammation of the lungs resulting from immunotherapy, their symptoms and restrictions in lung function can often only be alleviated with cortisone. Researchers led by Prof. Dr. Joachim Müller-Quernheim and Dr. Björn Frye from the Freiburg University Medical Centre have been able to cure a patient's pneumonitis by inhalation of a long-known neuropeptide.

    "Innate cell engagers" to fight cancer

    In the fight against tumour cells, d Affimed GmbH from Heidelberg relies entirely on the weapons of the innate immune system. Affimed has developed special innate cell engagers, which are bispecific antibodies that recognise tumour cells and bring them together with natural killer cells and macrophages of the innate immune system, which then kill the tumour cells. Clinical trials using the AFM13 molecule are ongoing.

    Microbiome: human health is closely connected with our microbial communities

    People have 1.3 times more microorganisms than body cells. This microbial community influences how we digest our food, how active our immune system is, as well as whether we tend to be more anxious or curious. A number of diseases have also been shown to be associated with a disturbed microbiome. Researchers still have a long way to go before the knowledge acquired can be used for developing therapies.

    Using CAR T cells for treating cancer

    After successes in the treatment of advanced blood cancers, CAR T-cell immunotherapy has become a major beacon of hope in oncology. The first therapies have received regulatory approval. Despite their success, these immunotherapies can have serious side effects. The company AVA Lifescience develops antibodies with high tumour specificity to use as the basis for effective precision-guided CAR T-cell therapies that are better tolerated by patients.

    Since 2012, a DFG-funded research group called FOR1680 has been studying CRISPR-Cas, an immune system that unicellular bacteria and arachaea use to protect themselves against attacks from viruses and plasmids. Prof. Dr. Anita Marchfelder, a molecular biologist at Ulm University and coordinator of the FOR1680 research group, and many other researchers were surprised to find that prokaryotes incorporate the genetic material of enemies as a kind of…

    Hepatitis B and hepatitis C are two of the most common infectious diseases in the world. They often take a chronic course and carry a high risk of progressing to cirrhosis and hepatocellular carcinoma. A new transregional collaborative research centre involving scientists from Heidelberg and Freiburg is looking into how hepatitis B and hepatitis C viruses, which have different symptoms and treatments, are able to evade the immune system and allow…

    The toxin of natural killer cells

    Natural killer cells kill tumour cells by injecting the protein HMGB1, which blocks the production of cellular energy by aerobic respiration. Researchers from Heidelberg have elucidated this previously unknown cancer defence mechanism and are now in the process of developing a new immunotherapy for treating cancer patients.

Crossed-out grey virus cells below the host cell indicate that the viruses are no longer able to replicate.

    Atriva Therapeutics GmbH: new ways to treat influenza

    Influenza viruses constantly change and mutate. This makes treatment difficult and vaccination rather touch and go. But what about targeting virus-manipulated cell events rather than using the virus itself as drug target? Atriva Therapeutics GmbH, a start-up company from Tübingen, shows how this works.

    Hip and knee endoprostheses are not nearly as long-lasting as their natural counterparts. Dr. Ulrike Dapunt from the University Hospital Heidelberg’s Department of Orthopaedics and Traumatology has now discovered that it is not the bacterial activity or secretions that lead to the degradation of bone during chronic inflammation, but rather local host defence mechanisms.

    Activation of the innate immune system against metastatic colorectal cancer

    Researchers from Heidelberg have shown that instead of fighting cancer cells, macrophages of the innate immune system promote the growth of metastases in people with metastatic colorectal cancer. They have also shown that a signal inhibitor used to treat HIV infections reactivates macrophages so that they gain the ability to destroy cancer cells. A clinical phase I study has confirmed the antitumoral effects of this drug.

    CRISPR/Cas – genome editing is becoming increasingly popular

    The number of publications and patents that involve the CRISPR/Cas system has been increasing exponentially since the technique was first described a few years ago. The increase in funding for projects involving CRISPR/Cas also demonstrates how powerful this new method is. The targeted modification of genomes (also called gene editing or genome editing) using CRISPR/Cas is extraordinarily accurate and also has the potential to cure hereditary…

Dr. Tobias Böttler from the Freiburg University Medical Center and his team are exploring the body’s immune response to the hepatitis C virus (HCV) and have found valuable information that could be used for vaccine development.

    Many viruses enter cells by way of carbohydrate molecules known as glycans to which they bind during the initial steps of infection. However, it is still largely unknown how glycan-mediated infection proceeds. This is about to change with a working group that has been set up by the DFG at the University of Tübingen and five other universities. The group will focus on glycovirology, a new scientific area that aims to understand the…
