Acetate supports immune cells to fight against sepsis

Blood poisoning is the most dangerous complication of bacterial infections and often leads to death. Researchers at the Interfaculty Institute of Microbiology and Infection Medicine at the University of Tübingen have now identified acetate as a potent agent for stimulating innate immune system cells, supporting their ability to destroy bacteria.

EMBL scientists pave the way for reducing the harmful side effects antibiotics have on gut bacteria. Antibiotics help us to treat bacterial infections and save millions of lives each year. But they can also harm the helpful microbes residing in our gut, weakening one of our body’s first lines of defence against pathogens and compromising the multiple beneficial effects our microbiota has for our health.

New drugs are intended to help stop viral zoonoses – infections that jump from animals to humans. To study suitable inhibitors, Prof. Dr Christian Klein from the Institute of Pharmacy and Molecular Biotechnology (IPMB) of Heidelberg University is receiving funding in the amount of 450,000 euros from the Volkswagen Foundation.

Immunologists at Ulm University and its Medical Centre have developed a new model that could revolutionise the treatment of autoimmune disease as well as vaccine development. As 'Adaptive Tolerance' demonstrates, autoreactive antibodies are by no means disease drivers which a healthy organism swiftly eliminates. Rather, they trigger the formation of a class of antibodies that protect the body's own structures.

Age-related macular degeneration (AMD) is the commonest cause of blindness in developed countries affecting seven million in total in Germany, from which 500,000 people are suffering from late stage disease, around half of whom are registered as visually impaired. There are two forms of AMD, ‘wet’ and ‘dry’. There are currently no treatments available for the dry form of the disease (geographic atrophy).

The bacterium Staphylococcus epidermidisis primarily a harmless microbe found on the skin and in the noses of humans. Yet some strains of this species can cause infections – in catheters, artificial joints, heart valves, and in the bloodstream – which are difficult to treat. These bacteria are often resistant to a particularly effective antibiotic, methicillin, and are among the most feared germs in hospitals.

Vaccine development - 25/05/2021

Vaccines – a beacon of hope in the fight against pandemics

Having long been considered less lucrative for the big pharmaceutical companies, vaccine development is taking off in an unforeseen way in the wake of the COVID-19 pandemic. Financial support is flooding in and all kinds of vaccine development strategies are being deployed. Among the winners in the competition for effective coronavirus vaccines are vaccines based on RNA technology. The development of much-needed vaccines against many other…

Signal mechanisms in inflammatory processes - 18/05/2021

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…

Nanobodies for determining neutralising antibodies after corona infection

After contact with a pathogen, ideally our immune system generates neutralising antibodies to prevent a future infection. With NeutrobodyPlex, scientists from Reutlingen and Tübingen have developed a highly specific test procedure based on single-domain antibodies (nanobodies) that can be used to easily and reliably determine the quality of the immune response against the novel coronavirus.

Epigenetic switches in bacteria as biosensors

The analysis of pathogen biomarkers and biomarkers for the diagnosis of diseases can be crucial for health. However, the detection of pathogens and diseases depends on a sensitive and reliable method that delivers rapid results. Biosensors have such properties. Researchers at the Institute of Biochemistry and Technical Biochemistry (IBTB) at Stuttgart University have constructed an epigenetic circuit composed of plasmids that might make it…

Do BMMFs, the novel infectious agents found in dairy products and bovine sera, play a role in the development of colorectal cancer? Scientists led by Harald zur Hausen detected the pathogens in colorectal cancer patients in close proximity to tumors. The researchers show that the BMMFs trigger local chronic inflammation, which can cause mutations via activated oxygen molecules and thus promote cancer development in the long term.

So-called silent mutations have no effect on the composition of a protein. They are therefore not considered to promote cancer. However, scientists from the German Consortium for Translational Cancer Research (DKTK), partner site Essen, now describe in a case of kidney cancer an overlooked silent mutation with a major impact on prognosis.

Whole blood model enables development of early warning system for sepsis

Sepsis is a life-threatening disease that can be treated all the more successfully the faster therapy is initiated. It is not just the infection itself that is so dangerous, but a dysregulated response of the immune system. Physicians at Ulm University Hospital have now developed an animal-free test system that can be used to research the disease and develop innovative diagnostic tools to quickly assess a patient's sepsis risk and optimise…

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.

A specific variant of the surface protein VSG of African trypanosomes, the causative agents of sleeping sickness, is associated with resistance to the important drug Suramin. Scientists at the German Cancer Research Center have now been able to find a possible explanation for the formation of resistance based on the crystal structure of this protein variant.

Gene accordions as potential markers for pathogenic properties

Bacteria must react to changes in the environment in order to survive. This is partly done by adapting genetic material, for example by multiplying and shortening individual genome segments. The research group led by Dr. Simon Heilbronner from the Interfaculty Institute of Microbiology and Infection Medicine at the University of Tübingen has shown that these so-called gene accordions are frequently found in the bacterium Staphylococcus aureus.

The chain reaction which leads to toxic protein deposits in Alzheimer’s disease starts even earlier than assumed. Researchers from Tübingen show how this process could be stopped early on.

To ensure that sepsis patients receive appropriate antibiotics as quickly as possible, Fraunhofer IGB researchers have developed a diagnostic procedure that uses high-throughput sequencing of blood samples and delivers results much faster than conventional culture-based techniques. Thanks to the latest single-molecule sequencing techniques, this process has now been further improved so that pathogens can be identified after just a few hours.

Intestinal peptide heals lung - 14/10/2020

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.

Next generation vaccine production

For decades, conventional inactivated vaccines have been produced by killing pathogens with toxic chemicals. However, this process often changes the surface structure of the pathogens to such an extent that the immune system is only able to induce a weak response. KyooBe Tech GmbH is offering a method that uses low-energy electrons to inactivate pathogens. Vaccines produced this way are much higher quality, making them safer and more effective.

Bosch has developed a new rapid test for its Vivalytic analysis device to detect the SARS-CoV-2 pathogen. The test provides a reliable result in 39 minutes and is currently the fastest polymerase chain reaction (PCR) test worldwide.

Mosses for pharmaceutical production - 16/09/2020

Factor H as a therapeutic option for viral diseases - including COVID-19

The search for drug candidates for COVID-19 diseases is well underway. Factor H, which is part of the innate immune system, might also be a future therapeutic option. The Freiburg-based biotech company eleva has developed a technology for producing this human protein in moss cells. The active ingredient, which might also have a regulatory effect in other diseases, is currently undergoing preclinical testing.

Infections pose an increasing risk to hospitalized patients. In collaboration with a number of partners, the Fraunhofer IGB has developed a new therapeutic approach as part of the InnateFun project. Their strategy is to improve cells’ ability to defend themselves against harmful microorganisms by acting on their immune receptors. The researchers’ work on this therapeutic approach has reached the animal model stage.
