New study: vaccine therapy for treating patients with chronic leukaemia

Personalised peptide vaccination is expected to improve the treatment of patients with chronic lymphocytic leukaemia. A research team from Tübingen has started a Phase I clinical trial with CLL patients who will undergo ibrutinib treatment. Other leukaemia sufferers as well as cancer patients in general are also expected to benefit in the long term.

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.

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 particular type of dendritic cell is responsible for the tissue damage that occurs in non-alcoholic steatohepatits (NASH) in mice and humans. The dendritic cells cause aggressive, proinflammatory behavior in T cells, as now discovered by researchers from the German Cancer Research Center (DKFZ) in collaboration with colleagues from Israeli research institutes. Blocking these dendritic cells alleviates symptoms in mice.

The working group around Dr. Philipp Rathert at the Institute for Biochemistry and Technical Biochemistry investigates the regulation of epigenetic networks of certain cancers and ways of treating them. The working group published its new findings in April.

Atriva Therapeutics GmbH, a company that is pioneering the development of therapies for the treatment of viral infections, has secured up to €11.4 million in federal funding. The company, founded in 2015, announced today that it was selected for research funding from the German Federal Ministry of Education and Research (BMBF). Atriva will use the funds to advance its drug ATR-002 towards market maturity as quickly as possible.

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. However, the production of these therapeutic cells using viruses is not only expensive but time-consuming. Researchers at the German Cancer Research Center (DKFZ) have developed an innovative non-viral vector that can efficiently introduce therapeutic genes into immune cells.

Tumor vaccines can help the body fight cancer. Mutations in the tumor genome often lead to protein changes that are typical of cancer. A vaccine can alert the patients' immune system to these mutated proteins. For the first time, physicians and cancer researchers from Heidelberg and Mannheim have now carried out a clinical trial to test a mutation-specific vaccine against malignant brain tumors.

Immunotherapy using checkpoint inhibitors is effective in around a quarter of patients with liver cancer. However, to date, physicians have been unable to predict which patients would benefit from this type of treatment and which would not. Researchers from the German Cancer Research Center have now discovered that liver cancer caused by chronic inflammatory fatty liver disease does not respond to this treatment. On the contrary: in an…

CureVac N.V., a global biopharmaceutical company developing a new class of transformative medicines based on messenger ribonucleic acid (mRNA), today announced the publication of preclinical data demonstrating that their COVID-19 vaccine candidate, CVnCoV, protects against challenge infections with the SARS-CoV-2 Variant of Concern B.1.351 and a strain of the original SARS-CoV-2 B1 lineage (BavPat1) in a transgenic mouse model.

A new method allows stem cells and cancer stem cells to be studied at the single cell level and the resulting cell clones to be traced directly. Studying thousands of individual cells in parallel, the researchers combined the analysis of the genomic cancer mutations with the associated expression profiles.

Women have an increased risk of breast cancer if they have a family history of this disease. However, the risk may also be higher if first-degree family members have another type of cancer, according to a study by a team of scientists and physicians from the National Center for Tumor Diseases (NCT) Heidelberg, the German Cancer Research Center (DKFZ) and Heidelberg University Hospital (UKHD), as well as international colleagues.

Induced pluripotent stem cells (iPSC) are suitable for discovering the genes that underly complex and also rare genetic diseases. Scientists from the German Cancer Research Center (DKFZ) and the European Molecular Biology Laboratory (EMBL), together with international partners, have studied genotype-phenotype relationships in iPSCs using data from approximately one thousand donors.

A new network has been set up in Baden-Württemberg aimed at reducing animal experiments as well as further improving animal welfare. It combines new approaches and measures at the state’s biomedical research locations, which are expected to limit stress in laboratory animals and steadily reduce the number of animals used in research in line with the 3R principles of Replacement, Reduction, and Refinement.

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.

Neuroblastoma can spread relentlessly or shrink spontaneously. Scientists from the Hopp Children’s Cancer Center Heidelberg (KiTZ), the German Cancer Research Center (DKFZ), the University of Heidelberg and the National Center for Tumor Diseases (NCT) Heidelberg have shown that some malignant neuroblastomas employ a trick to avoid cell death: they use a special mechanism to lengthen the telomeres at the end of their chromosomes.

Researchers from EMBL and Heidelberg University Hospital combine high-resolution imaging to observe the infection process in cell nuclei, opening the door for new therapeutics.

An international research team involving the universities of Paraná and Tübingen has developed a rapid test that can reliably identify Covid-19 antibodies in the blood within minutes. As the researchers report in the journal ACS Sensors, the new process is based on a simple measuring principle making it easy to carry out without expensive instruments, and is therefore suitable for use at mobile testing centers or by laboratories.

Can interconnected digital assistance systems enhance the quality of life of people in older age? Scientists in an interdisciplinary research project at Heidelberg University are exploring this question in a representative practice study. The participating researchers want to investigate how well these technical aids can be used and what benefit they achieve.

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.

CureVac N.V., a global biopharmaceutical company developing a new class of transformative medicines based on messenger ribonucleic acid (mRNA), today announced the publication of preclinical data demonstrating the induction of robust antibody and T cell responses of its COVID-19 vaccine candidate, CVnCoV, in non-human primates.

A study by the University of Konstanz shows that voluntary motivation to comply with anti-Covid-19 policies is relatively high in Germany, but can be undermined by enforcement - The consequence of this finding differs depending on the policy.

The Freiburg engineer and biologist Prof. Dr. Barbara Di Ventura receives a Consolidator Grant from the European Research Council (ERC), one of the most prestigious prizes for European researchers, for her project "InCanTeSiMo - Intelligent cancer therapy with synthetic biology methods". Di Ventura will use the 2 Million Euros to develop a novel cancer treatment based on molecular methods from synthetic biology.

AI-based evaluation of medical imaging data usually requires a specially developed algorithm for each task. Scientists from the German Cancer Research Center (DKFZ) have now presented a new method for configuring self-learning algorithms for a large number of different imaging datasets – without the need for specialist knowledge or very significant computing power.

A Phase I clinical trial using a self-developed vaccine against SARS-CoV-2 was initiated today at the University Hospital of Tübingen. In contrast to the currently evaluated vaccine candidates against COVID-19, the vaccine CoVAC1, developed by the Department of Immunology (Director Prof. Hans-Georg Rammensee) at the University of Tübingen, aims specifically at the induction of a T-cell-mediated immune response against SARS-COV-2.
