Working with a new Emmy Noether Group, Dr. Pascal Schlosser is investigating how machine learning can aid in understanding the complex relationships between genes, proteins, and diseases.

Tuberculosis is one of the leading causes of death worldwide, with an estimated 1.4 million deaths and ten million people infected annually. Resistant and multidrug-resistant (MDR) variants of the tuberculosis pathogen Mycobacterium tuberculosis pose a major threat to tuberculosis control and global health.

The newborn's immune system is suddenly confronted with microorganisms, food and numerous environmental influences at birth. How do the baby's immune cells prepare for this moment during pregnancy and birth? How do external influences shape the immune system immediately after birth? And what influence does an event like a premature birth have?

The two inter-university funding programs SEED4EU+ and 4EU+ Visiting Professorships are entering a new round of calls. With these programs, the 4EU+ European University Alliance pursues the goal of strengthening links between the eight partner universities, giving scope to new ideas and supporting inter-university projects.

CRISPR/Cas – genome editing is becoming increasingly popular

The number of publications and patents that involve the CRISPR/Cas system has been increasing exponentially since the technique was first described a few years ago. The increase in funding for projects involving CRISPR/Cas also demonstrates how powerful this new method is. The targeted modification of genomes (also called gene or genome editing) using CRISPR/Cas is extraordinarily accurate and also has the potential to cure hereditary diseases.

Mitochondria are considered to be the power plants of cells and are essential for human metabolism. Dysfunction in 40 percent of mitochondrial proteins are associated with human diseases, which is why mitochondria also play an important role in medical research. A previously unexplained process in the complex mitochondria was the formation of their barrel pores.

The challenge: if conventional speaking valves are used improperly, dangerous overpressure can occur, which can cause serious complications and even death. In a collaboration at the University of Freiburg, researchers developed a speaking valve with an integrated pressure release valve and an acoustic warning signal, inspired by the trapping mechanism of the carnivorous bladderwort plant Utricularia vulgaris.

Although just cute little creatures at first glance, the microscopic geckos and octopuses fabricated by 3D laser printing in the molecular engineering labs at Heidelberg University could open up new opportunities in fields such as microrobotics or biomedicine. The printed microstructures are made from novel materials – known as smart polymers – whose size and mechanical properties can be tuned on demand and with high precision.

Triple-negative breast cancer (TNBC) is the most aggressive and deadly form of breast cancer with limited treatment options. Tumor growth and relapse of TNBC are driven by breast cancer stem cells, and improved therapies that can eliminate those hardy cells are urgently needed. Researchers from the University of Frieburg discovered that coordinated differentiation and changes in the metabolism of breast cancer stem cells make them invisible for…

Inflammation has to work fast against pathogens—but it can't get out of control. Researchers at the German Cancer Research Center (DKFZ) have now deciphered in more detail how the organism masters this balancing act. Their work shows that cells use two different strategies to precisely control inflammatory genes and thus precisely regulate the inflammatory response.

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.

Acute Graft-versus-host disease (GvHD) is a life-threatening complication after leukemia treatment with allogeneic stem cell transplantation i.e. the transplantation of cells from another person. GvHD occurs when the transplanted immune cells are overly active and damage the receiving patient's healthy tissue. Researchers found that an endogenous molecule can mitigate this misdirected immune response.

Effective drugs against viral diseases like COVID-19 are urgently needed now and in the future. The emergence of viral mutants and yet unknown viruses could push vaccines to their limits. The DZIF scientist and bioinformatician Andreas Dräger from the University of Tübingen is working on a computer-based method that can help to accelerate the time-consuming identification and development of antiviral agents. Using a novel analysis technique that…

Researchers at the Faculty of Medicine at the University of Freiburg have gained significant new insights into metabolic processes in the kidney. The scientists from the Institute of Genetic Epidemiology at the Medical Center - University of Freiburg measured tiny molecules, so-called metabolites, which occur in blood and urine and reflect our metabolism, in samples from more than 5,000 study participants.

Targeted molecular interventions in the replication cycle and the immune recognition of viruses are intended to prevent viral entry into cells and virus replication. Scientists work on new approaches to combating highly dangerous viral diseases such as yellow fever or Lassa fever. The European Union is supporting the project over a period of five years to the tune of just under eight million euros.

A team of engineers and biotechnologists at the University of Freiburg has for the first time shown in mammals that the concentration of antibiotics in the body can be determined using breath samples. The breath measurements also corresponded to the antibiotic concentrations in the blood. The team’s biosensor – a multiplex chip – will in future enable personalized dosing of medicines against infectious diseases on-site.

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.

Non-profit limited liability company creates institutional framework for interdisciplinary research collaboration, innovative technology development and outstanding healthcare in the Rhine-Neckar region.

Known as the power plant of the cell, mitochondria are essential to human metabolism. Human mitochondria consist of 1,300 different proteins and two fatty biomembranes. The vast majority of mitochondrial proteins are produced with a cleavable transport signal and have to be actively transported into the mitochondria.

CAR-T cell therapy is a last hope for many patients with blood, bone marrow or lymph gland cancer when other treatments are unsuccessful. A limiting factor of this very effective and safe therapy is that the cells used in the process quickly reach a state of exhaustion. Researchers at the University of Freiburg have now been able to prevent this exhaustion and thus significantly improve the effect of the therapy in a preclinical animal model.

More than seven million people in Germany suffer from diabetes. At the same time, research into drugs to treat this widespread disease is still difficult. Scientists led by Prof. Dr. Peter Loskill from the NMI Natural and Medical Sciences Institute and the Faculty of Medicine of the Eberhard Karls University of Tübingen have now developed a technique that significantly improves the view at the molecular and cell biological level in the pancreas.

An international research team has deciphered a mechanism of evolutionary arms race in human cells. The findings provide insights into how mobile elements in DNA hijack cellular functions – and how cells can defend themselves against this in order to prevent conditions such as tumour formation or chronic inflammation.

The ability of cancer cells to change their identity makes tumors such as glioblastoma particularly aggressive and resistant to treatment. Moritz Mall, of the German Cancer Research Center (DKFZ) and the Hector Institute for Translational Brain Research (HITBR), is investigating how this plasticity can be specifically restricted. His approach focuses on genetic “guardians” that suppress alternative cell programs.

Scientists from the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) have developed antibodies that have two antigen-binding sites and can couple cancer cells with effector cells of the immune system. In laboratory tests, these bridging antibodies, together with an enhancer antibody, were able to specifically mobilize the body's own immune defenses and destroy breast cancer cells.

Konstanz biologist Patrick Müller receives a Proof of Concept Grant from the European Research Council for his project "EmbryoNet-AI". Its goal is the further development of an AI-supported platform for the automated evaluation of experiments – for example, in drug development.
