Screening trials for the early detection of rare diseases often fail due to insufficient predictive power of the results. For the rare HPV-related cancer of the pharynx, scientists from the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) now relied on the combined detection of antibodies against two different viral proteins in a proof-of concept trial.

CureVac N.V. (Nasdaq: CVAC), a global biopharmaceutical company developing a new class of transformative medicines based on messenger ribonucleic acid (“mRNA”), today announced the publication entitled “Therapeutic HNF4A mRNA attenuates liver fibrosis in a preclinical model” in the peer-reviewed Journal of Hepatology.

High-resolution microscopy technology bypassing the diffraction limit - 26/10/2023

From micro- to nanoscope

It has long been impossible to distinguish objects closer than 200 nanometres using light microscopes. However, novel devices developed by a company called abberior Instruments GmbH, which use technology developed by Nobel Prize winner Prof. Dr. Stefan Hell and his teams in Heidelberg and Göttingen, are now able to bypass this resolution limit and provide detailed insights into living cells in the lower nanometre range.

Activated T cells that carry a certain marker protein on their surface are controlled by natural killer cells. In this way, the body presumably curbs destructive immune reactions. Researchers now discovered that NK cells can impair the effect of cancer therapies with immune checkpoint inhibitors in this way. They could also be responsible for the rapid decline of therapeutic CAR-T cells.

The development of highly specific T-cell engagers directed against pHLA tumor targets will be quick and easy. BioCopy's innovative pHLA screening technology characterizes drug candidates in great depth for their specific binding against the desired pHLA tumor target. YUMAB develops highly specific antibodies with their advanced antibody technologies.

Scientists from the German Cancer Research Center and Heidelberg University Hospital have for the first time been able to delay the development of hereditary colorectal cancer with a protective vaccination. Mice with a hereditary predisposition to colorectal cancer survived significantly longer after vaccination than unvaccinated animals. Combining the vaccination with an anti-inflammatory drug increased the protective effect.

Peptide-based COVID-19 vaccine - 21/04/2022

CoVac-1: T-cell activator against COVID-19

Current vaccines against COVID-19 aim at forming neutralising antibodies that prevent the virus from penetrating the host cells. Since people with impaired B-cell immune responses – which can also occur in cancer or autoimmune diseases – are not able to do this, researchers at the University of Tübingen have developed the peptide-based T-cell activator CoVac-1, which promises broad and long-term immunity.

Peptides diverse molecules of life

Peptides exist in all organisms, wherever there are cells. The range of their physiological functions is huge. Biologically active peptides can act as hormones, neurotransmitters, growth factors as well as toxins and antibiotics. This is what makes them highly interesting drug leads. They are used for the treatment of autoimmune diseases, cancer and other diseases. Peptides are gaining in importance as candidates for drugs.

Heidelberg scientists succeed in boosting the efficiency of CRISPR/Cas9 and related methods and modifying initially inaccessible DNA sequences.

The hospital pathogen Pseudomonas aeruginosa requires the sugar-binding proteins LecA and LecB to form biofilms as well as to attach to and penetrate host cells. These so-called lectins are therefore suitable targets for active substances to combat Pseudomonas infections. Researchers from Saarbrücken and Freiburg have now produced potent inhibitors for LecA and LecB that are more stable and soluble than previous drug candidates.

COVID-19 pioneer drug in Phase II clinical trial - with double the power

The effective treatment of people with severe COVID-19 is a major goal during the corona pandemic. ATR-002, an oral small molecule that targets RNA viruses such as influenza virus and SARS-CoV-2, has a dual effect: it impairs viral propagation and also has an immunomodulatory effect. And what’s more, due to its unique cellular mechanism of action, the efficacy of Atrivia Therapeutics’ drug candidate is not reduced by virus mutations and…

Brain tumor cells with a certain common mutation reprogram invading immune cells. This leads to the paralysis of the body's immune defense against the tumor in the brain. Researchers from Heidelberg, Mannheim, and Freiburg discovered this mechanism and at the same time identified a way of reactivating the paralyzed immune system to fight the tumor.

A high-fat, high-sugar diet damages the liver in the long term. Scientists at the German Cancer Research Center (DKFZ) have now identified a characteristic change in the molecular signaling pathways of liver cells in mice that were exposed to such a diet for weeks. It fuels the division activity of hepatocytes and correlates with the risk of patients suffering liver failure after liver surgery.

While broad-spectrum antibiotics can offer protection against a wide variety of bacteria, there are currently no analogous clinically available broad-spectrum antiviral agents that can act on several different viruses.

Do gut bacteria have something to do with autism?

Autistic people have different gut microorganisms than non-autistic people. Researchers believe that a disturbed intestinal flora may play a role in developmental disorders of the brain such as autism.

Viral cancer therapy - 26/10/2022

Therapeutic viruses against tumours and metastases

Viruses can overcome cell barriers and transfer information to their host cells. They know how to make their host cell’s infrastructure work for them. This makes them excellent biotechnological tools, which a research group from the Fraunhofer IGB in Stuttgart is using to its advantage. The team is developing a therapeutic virus that not only recognises and fights tumours, but also has the potential to reach metastases.

Genetically enhancing a patient's immune cells by adding therapeutic genes to them outside the body is regarded as a promising new treatment approach in oncology.

The project’s goal is to systematically and comprehensively analyse…

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.

Through a complex, self-reinforcing feedback mechanism, colorectal cancer cells make room for their own expansion by driving surrounding healthy intestinal cells to death - while simultaneously fueling their own growth. This feedback loop is driven by an activator of the innate immune system.

On the one hand, blood vessels supply tumors with nutrients and, on the other, enable cancer cells to spread throughout the body. The settlement of circulating tumor cells in a distant organ is promoted by factors whose production is induced by the primary tumor itself. Scientists have now identified a new growth factor produced by blood vessels that enables tumor cells to metastatically colonize organs.

During infections, the hematopoietic system switches from normal to emergency mode. This improves the defense against the pathogens. Scientists at the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) have now found an epigenetic switch in blood stem cells and progenitor cells of mice that can trigger the switch from one mode to the other.
