Help with osteoarthritis of the knee - 27/09/2023

Individualised knee-joint cartilage: artificial tissue that fits

Knee joints are subject to considerable stress throughout our lives. The natural shock absorber cartilage wears out over a lifetime, so many people develop knee osteoarthritis. Treatment is available in the form of artificial cartilage. This "off-the-shelf" tissue often does not grow well. Researchers are developing an individualised cartilage replacement made from biomaterial that is produced by 3D printing based on MRI images.

Tumor vaccines can help the body fight cancer. These vaccines alert the patient's immune system to proteins that are harbouring cancer-typical alterations. Physicians and cancer researchers from Heidelberg and Mannheim have now treated adult patients with advanced midline gliomas, difficult-to-treat brain tumors, with a peptide vaccine for the first time.

Current diagnostic methods do not always reliably distinguish between chronic inflammation of the pancreas and pancreatic cancer. About one third of all diagnoses are inconclusive. Scientists from the German Cancer Research (DKFZ) and from Heidelberg University Hospital (UKHD) therefore searched for molecular markers that could specify this diagnosis.

The computational design of new proteins for biomedical or other applications involves long computing times on powerful servers. A joint team of researchers from the Max Planck Institute for Biology Tübingen and the University Hospital Tübingen has now developed and tested a new computational method to greatly speed up the necessary energy calculations. Their framework allows for a precise and efficient design of functional proteins.

Artificial cytoskeleton made of DNA for synthetic cells

The physicists Prof. Dr. Kerstin Göpfrich and Prof. Dr. Laura Na Liu want to understand life from the bottom up. They intend to do this by constructing an artificial cell. However, rather than natural protein building blocks, they are using 3D-DNA structures as construction material. The first step involved creating an artificial cell skeleton that dynamically assembles and disassembles like the biological model and can transport vesicles.

Germany has the most active market, Southern Europe wants more variety, and people in Poland find dairy substitutes too expensive, according to a recent study by the University of Hohenheim.

Project BlindZero - 03/08/2023

Hope for patients with eye diseases: human cornea from 3D printers

Thousands of cornea transplants are performed every year. However, donors are rare and the procedure is not always without complications. Researchers at the University of Heidelberg are developing an innovative technique in the project BlindZero. It involves ‘printing’ human corneas directly onto patients’ eyes using 3D bioprinting. The reprogrammed genetically engineered cells used for this purpose are not expected to cause a rejection reaction.

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.

Immune complexes in COVID-19 - 01/03/2023

Vicious circle of hyperinflammation

Whether a person experiences only a mild malaise or a critical course of disease after a coronavirus infection apparently depends on the antigen-antibody complexes that form in our body. The discovery of these immune complexes set a group of researchers, headed up by Prof. Dr. Hartmut Hengel from the Freiburg University Medical Centre, on the trail of a vicious circle of constantly escalating inflammation.

Paetzold and chemist Frank Biedermann will receive approximately two million euros over the next five years.

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.

Interferons represent the first line of defence against viral infections and are at the same time an important cause of the age-related loss of function of brain stem cells. Scientists from the German Cancer Research Center (DKFZ) and the University of Heidelberg have now shown in mice that interferon regulates the activity and self-renewal of brain stem cells throughout life.

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.

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.

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.

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.
