Cancer immunotherapies often fail because the immune cells are paralysed by immunosuppressive conditions in the tumor. Scientists from Heidelberg, Mannheim and Tel Aviv have now shown on tissue samples from patients as well as on tumor models in mice that the functionality of the immune defence depends decisively on certain helper cells.

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

Brain-computer interfaces are able to restore some mobility to paralyzed people by controlling exoskeletons. However, more complex control signals cannot yet be read from the head surface because conventional sensors are not sensitive enough. A collaboration of Fraunhofer IAF, Charité – Universitätsmedizin Berlin, University of Stuttgart and other industrial partners has taken up this challenge.

Dialogue instead of a chemical maze – new strategy for sustainable crop protection

Climate change creates stress. This provides an opportunity for pests to exploit plant weaknesses and reproduce. For the infested plant, this can be catastrophic and often fatal. But instead of continuing to protect harvest yields with toxic substances as before, the transnational DialogProTec project is now taking a completely new approach: researchers want to intervene in the communication between plants and pests to keep them healthy.

With the "Česká Hlava" awards, the Czech government has been honoring the country's most brilliant minds every year since 2002 and recognizing exceptional achievements in research, development and innovation. Martina Benešová-Schäfer of the German Cancer Research Center was among the six laureates honored in 2022 at Charles University in Prague.

After infections or blood loss, the body must compensate for the loss of blood cells as quickly as possible. This has long been considered the task of the hematopoietic stem cells in the bone marrow. But scientists at the German Cancer Research Center (DKFZ) have now discovered in mice that a certain population of progenitor cells takes over this task: This accelerates the regeneration of the blood cells.

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.

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.

GoDanuBio’s contribution to the bioeconomisation of the Danube Region

GoDanuBio supported the set-up of policy frameworks and participative governance schemes in the participating regions. The main topics were circular bioeconomy, sustainable rural development and rural-urban interactions.

Researchers at the University of Freiburg Medical School led by Prof. Dr. Johannes Letzkus and the Max Planck Institute for Brain Research have discovered that a little-studied area of the brain, the "zone of uncertainty" or "zona incerta," communicates with the neocortex in unconventional ways to rapidly control memory formation.

ValBio-Urban brings bioeconomy research to users

Reducing carbon dioxide emissions and the capture and utilization of CO2 are important steps towards achieving a climate-neutral and sustainable economy. Accordingly, as part of the ValBio-Urban research project, an interdisciplinary team from the University of Stuttgart is developing bioeconomic approaches to solutions that will be implemented with companies from Baden-Württemberg.

Using new microscopic methods in combination with machine learning-based image analysis, researchers from Freiburg have discovered new structures on the surface of living B cells that affect the distribution and possibly the function of their antigen receptors. The researchers' study has been published in The EMBO Journal.

Value-based healthcare - 11/01/2023

High-quality healthcare pays off

High-quality medical treatment is not only worthwhile for ill persons. The Division of Health Economics at the German Cancer Research Center in Heidelberg, headed up by Prof. Dr. Michael Schlander, together with researchers from Dresden, has carried out a cost-effectiveness analysis that shows that certified colon cancer centres provide not only better but also more cost-effective care than other clinics.

CureVac N.V. (Nasdaq: CVAC), a global biopharmaceutical company developing a new class of transformative medicines based on messenger ribonucleic acid (“mRNA”), today announced positive preliminary data from ongoing Phase 1 clinical programs in COVID-19 and seasonal flu, assessing both modified and unmodified mRNA technology. The tested vaccine candidates are being developed in collaboration with GSK.

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.

In our bones, specialized cells called osteoblasts are responsible for building up bone substance. A team of researchers led by scientists from the DKFZ-Hector Cancer Institute at the University Medical Center Mannheim* and the University Medical Center Hamburg Eppendorf has now identified an enzyme that controls the activity of osteoblasts.

Heidelberg scientists decode the genetic foundations of rapid testicle evolution in mammals and humans. Evolutionary pressure across male mammals to guarantee the procreation of their own offspring led to a rapid evolution of the testicle.

Inhibition of a protein complex in cells of the immune system prevents rejection of transplanted organs – this has been shown in a study by immunologists from the University of Konstanz, the Biotechnology Institute Thurgau (BITg) and Chongqing Cancer University Hospital.

A polyester plastic of great mechanical stability, which is also easily recyclable and even compostable: Stefan Mecking, chemist at the University of Konstanz, and his research group present a new material.
