Laboratory studies of lung tissue usually require the removal of large amounts of human or animal tissue. Now scientists from the University of Freiburg’s Faculty of Medicine have succeeded in collaboration with American researchers in generating tiny quantities of lung tissue, so-called organoids, from just a few body cells in the lab.

In order to develop approaches for the prevention and treatment of Alzheimer's dementia in clinical trials, it would be helpful to be able to identify people with a particularly high risk of developing the disease. But which biomarkers can indicate an increased likelihood of disease early on in symptom-free people who actually develop Alzheimer's later?

More and more data from various European countries prove: Vaccination against human papillomavirus not only prevents precancerous lesions, but also reliably protects against cervical cancer. On the occasion of the International HPV Awareness Day on March 4, Nobel laureate Harald zur Hausen hopes that many more parents will recognize this unique opportunity to protect their children from preventable cancers by vaccinating against HPV.

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.

CureVac N.V. (Nasdaq: CVAC), a global biopharmaceutical company developing a new class of transformative medicines based on messenger ribonucleic acid (“mRNA”), today announced that it has dosed the first participant in a Phase 1 study of its seasonal influenza second-generation mRNA vaccine candidate, CVSQIV, developed in collaboration with GSK.

The European Research Council is funding a large-scale proof-of-concept study on a new genome sequencing method called “Haplotagging”. Haplotagging is a new method for sequencing our genome with superior quality and faster speed, developed by group leader Frank Chan and his team at the Friedrich Miescher Laboratory at the Max Planck Campus, Tübingen, Germany.

Researchers use epigenetic factors to investigate the role of stress in the development of tumor diseases. Experts believe that stress plays a major role in the development of tumors. One occupational group, for example, that experiences extreme stress over a short period of time is astronauts.

Drugs consist of molecules developed in the drug laboratory that bind to their target, usually a protein, and thus exert their effect. The actual duration of binding of a drug molecule to its target protein varies depending on the drug. The lifetime of the drug-target complex can play a critical role in the efficacy of a drug, as a long residence time at the target can be crucial for the drug's action in some cases.

The incidence of colorectal cancers in young adults is increasing. At the same time, the proportion of overweight and obese young people is also on the rise. Whether there is a connection between these two observations, however, was not known until now. Scientists at the DKFZ have now shown that the risk of early colorectal cancer is significantly increased in overweight young people compared to normal-weight peers.

Genetic alterations that promote the development and spread of tumors are difficult to identify. This is especially true for mutations in the non-protein-coding regions of the genome, which include all important regulatory sequences. Scientists at the German Cancer Research Center have now published an algorithm that detects cancer drivers in both the protein-coding and non-coding regions of the genome.

Researchers at Heidelberg University Hospital (UKHD), the German Cancer Research Center (DKFZ) and at the National Center for Tumor Diseases (NCT) Heidelberg have demonstrated for the first time that there is a link between the development of colorectal cancer in individuals with Lynch syndrome and the composition of immune cells in the colorectal mucosa.

Today, the EU Parliament adopted the EU Regulation on Health Technology Assessment (HTA), which includes not only new medicines (including gene and cell therapies), but also medical devices.

A new interdisciplinary research project aims to uncover information that can help decode hereditary colon cancer with the aid of mathematical models. Mathematicians and tumour biologists of Heidelberg University, the Heidelberg Institute for Theoretical Studies, Heidelberg University Hospital, and the German Cancer Research Center are collaborating on the project.

The development of immunotherapies against blood cancer could be more successful if T cells are activated moderately rather than excessively. Scientists from the German Cancer Research Center have now been able to show this in mice: If the researchers blocked a cytokine that slows down the immune system, the T cells became exhausted and failed in the fight against leukemia.

At Tübingen University Hospital, a preclinical study led by Dr. Clemens Hinterleitner and Prof. Dr. Lars Zender, Medical Director of Medical Oncology and Pneumology, led to extremely promising results. The research group was able to develop a new methodology that makes it possible to better predict the likelihood of success of immunotherapies for lung cancer.

Parkinson's disease is characterised by a slow, progressive loss of nerve cells in certain brain areas. The disease is still incurable and the exact causes are unclear. The dopamine deficiency in the brain can only be controlled to some extent in the initial phase of the disease. Basic research is being conducted in an attempt to unravel the mystery of Parkinson's disease.

In multiple myeloma, a cancer of the bone marrow, relapse almost always occurs after treatment. Initially, most patients respond well to therapy. However, as the disease progresses, resistant cancer cells spread in the bone marrow, with fatal consequences for the patients.

After a highly competitive process Ulm University has been awarded its fifth Collaborative Research Centre (CRC). The new CRC 1506 ‘Aging at Interfaces’ addresses one of the most urgent medical challenges of our time: the aging of the human body and the diseases and constraints that are frequently associated with the aging process.

At the University Hospital Tübingen, clinical evaluation of an in-house developed vaccine (CoVac-1) against SARS-CoV-2 was started in November 2020 under the direction of Prof. Dr. Juliane Walz in the CCU Translational Immunology of the Medical Clinic (Medical Director Prof. Dr. Helmut Salih). Now the results of the Phase I study are available and demonstrate a potent activation of the T-cell response against the coronavirus.

Furtwangen University publishes the world’s first molecular biological study on bacterial contamination of slit lamps. Slit lamps are among the most important tools used by ophthalmologists and opticians. They allow selected areas of the eye to be magnified and examined for diseases.

As cancer progresses, the tumor cells continually change, ultimately resulting in a tumor consisting of a large number of different cell clones with different characteristics. This is referred to as "tumor heterogeneity". In many cases, the cancer cells become resistant to the treatments available.

Treatment resistance is a central problem in the treatment of cancer. Bone and soft tissue tumors – known as sarcomas – in adolescents and young adults often stop responding to treatment too. This is because cancer cells develop a large number of new characteristics as the disease progresses and often become resistant to drugs that were originally effective.

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.

Doctors and scientists from the German Cancer Research Center (DKFZ) and from Heidelberg University's Medical Faculty Mannheim have successfully tested a neoantigen-specific transgenic immune cell therapy for malignant brain tumors for the first time using an experimental model in mice.

Plastic products can be found everywhere in daily life, soft plastic in particular often being used for packaging or children's toys. These often contain so-called plasticizers which ensure that the material remains flexible. Because plasticizers are not bonded permanently to the plastic, they can escape from the material, meaning they can be absorbed by humans.
