Researchers at the German Cancer Research Center (DKFZ) have succeeded in identifying a resistance mechanism that often occurs in a specific targeted therapy against chronic lymphocytic leukemia (CLL). The drug ibrutinib is effective in many cases, but therapy resistance often develops during the course of treatment. In cell culture experiments and in mice, the resistance mechanism was successfully overcome using a second drug.

Stomach ulcers, gastritis and even stomach cancer are often the result of an infection with Helicobacter pylori. If the bacterium remains unrecognised for a long time, this can have serious consequences. Researchers have now developed a miniaturisable sensor system for the mobile analysis of breath that is effective, fast and inexpensive. The research team uses a biological survival trick of the stomach germ to detect the bacterium.

University of Tübingen research team shortens the search for attackers that can wipe out multiresistant pathogens – with the aim of treating infections without antibiotics

This year, the Brain Prize worth more than one million euros, honors pioneering work on nervous system-cancer interactions: Neurologist Frank Winkler, who researches at the Heidelberg University and at the German Cancer Research Center and treats patients with brain tumors at the Heidelberg University Hospital, discovered that nerve cells in the brain communicate with brain tumor cells. This causes the disease to progress.

In collaboration with Heraeus, the German Institutes of Textile and Fiber Research (DITF) are developing fibers and textiles with a novel infection protection system. The basis is an antimicrobial mechanism of action licensed from Heraeus and marketed under the name AGXX. The goal of the collaboration is to optimally integrate the AGXX technology into textile finishes and coatings and to incorporate it into fiber-spinnable polymers.

Tumor cells circulating in the blood are the "germ cells" of breast cancer metastases. They are rare and could not be propagated in the culture dish until now, which made research into therapy resistance difficult. A team from the DKFZ, the Heidelberg Stem Cell Institute HI-STEM and the NCT Heidelberg has now succeeded for the first time in cultivating stable tumor organoids directly from blood samples of breast cancer patients.

Chromosomal instability plays a role in the progression of cancer: it shapes the properties of tumor cells and drives the development of therapy resistance. Scientists from the German Cancer Research Center (DKFZ), the Heidelberg Stem Cell Institute HI-STEM* and the European Molecular Biology Laboratory (EMBL) used state-of-the-art single-cell analysis methods to analyze the cellular heterogeneity of a specific form of acute myeloid leukemia.

Rethinking plastics in medical technology

Good healthcare relies heavily on medical products made from plastic. However, the widespread use of synthetic materials, particularly disposable items, creates vast amounts of waste, depletes resources and leads to a substantial carbon footprint. To create more environmentally friendly plastic products in the future, substantial changes to production processes are essential.

Personalized medicine with individually tailored therapies is becoming more a reality in cancer. This requires a look into the genetic material of tumors, a molecular diagnostic tumor profile. A research group from the German Network for Personalized Medicine (DNPM) has recorded the quality standards according to which genome analyses are carried out in Germany. The data is a prerequisite for integrating gene sequencing into routine care.

App for tuberculosis diagnosis - 15/05/2024

"Find-TB" aims to improve access to tuberculosis diagnostics

Globally, the majority of children with tuberculosis remain undiagnosed and therefore untreated because their symptoms are categorised incorrectly. Researchers at Heidelberg University Hospital want to develop an app that analyses medical information, risk factors and local surveillance data to calculate individual risk of infection and test those who might be affected with TB as early as possible.

Professor Claudia Denkinger from Heidelberg University's Faculty of Medicine is leading the international collaborative project "BreathForDiagnosis". Researchers from Germany, Italy, South Africa and Romania are working with an industrial partner from Switzerland to develop user-friendly breath tests for the rapid diagnosis of respiratory infections such as tuberculosis.

Fatty liver disease often leads to chronic liver inflammation and can even result in liver cancer. Scientists from the German Cancer Research Center (DKFZ) and the University of Tuebingen have now shown in mice that intermittent fasting can halt this development.

PhD student at Furtwangen University develops method for faster determination of antibiotic resistance. The increase in antibiotic-resistant pathogens and the associated treatment, which is a major problem in public healthcare facilities, is the subject of a research project at Furtwangen University.

The market for medical technology is innovative, dynamic, and growing. Bosch sees medical technology as a strategic growth field and intends to expand its Bosch Healthcare Solutions subsidiary, based in Waiblingen. Bosch has now entered into a new partnership with the German diagnostics solutions company R-Biopharm. This partnership will be focused on Bosch’s universal, fully automated Vivalytic molecular diagnostic analysis platform.

Epifadin from the nasal microbiome - 28/03/2024

From the nose: novel antibiotic substance discovered

Antibiotics are becoming an increasingly blunt weapon against infectious diseases. The number of (multi-)resistant germs has been rising rapidly for years and even reserve antibiotics no longer work. Researchers at the University of Tübingen have now isolated a completely new antibiotic substance called epifadin from the microbiome of the human nose. It is effective against many different bacteria - including the dangerous hospital MRSA.

More than 65,000 men fall ill with prostate cancer each year in Germany. Twelve thousand of them develop a treatment-resistant form which eventually ends in death. Now, a team of researchers from the Medical Faculty at the University of Freiburg has developed an active substance that might in future represent a new treatment option.

Mutations of the tumor suppressor p53 not only have a growth-promoting effect on the cancer cells themselves, but also influence the cells in the tumor's microenvironment. Scientists at the Weizmann Institute in Israel and at the German Cancer Research Center (DKFZ) have now shown that p53-mutated mouse breast cancer cells reprogram fat cells.

For the first time, the active substance epifadin has been isolated at the University of Tübingen – Epifadin is produced by specific bacteria in the nose and on the skin of humans, has an antibiotic effect, and is the first example of a previously unknown antimicrobial compound class.
