Augmented reality for visual orientation - 15/11/2023

Fall prevention with the help of balance-enhancing AR glasses

As we age, our eyesight deteriorates and we have increasing difficulties with orientation. This can lead to balance problems and fatal falls. A team led by Dr. Lorenz Assländer from the University of Konstanz is currently developing a prototype of augmented reality (AR) glasses that use superimposed patterns to facilitate visual orientation in space, thereby helping to improve balance control and prevent falls.

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.

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.

A new study published in Nature Medicine, July 2023 has identified two novel markers for screening high-grade squamous intraepithelial lesions (HSIL), a precursor to anal cancer, from the anal microbiome of people with HIV (PWH). PWH are at a significantly higher risk of developing anal cancer. Current screening methods, such as anal cytology, have low specificity for detecting HSIL, which hinders the prevention of anal cancer.

The function of mast cells, which are part of the immune system, is still a mystery. Scientists at the German Cancer Research Center (DKFZ) have now shown in mice: mast cells function as a sensor that signals the animals to avoid antigens, including harmful allergens, and thereby protect themselves from health-threatening inflammatory reactions. The findings were published in the journal Nature.

Rejuvenating skin and preventing skin cancer: That is the vision of the scientists at the new Joint Innovation Lab, which Beiersdorf and the German Cancer Research Center (DKFZ) founded on July 1, 2023. In the jointly operated lab, researchers are taking a close look at the "epigenetic clock" of skin cells with the aim of turning back biological aging and thus also reducing the risk of skin cancer.

Researchers from Konstanz and Zurich have deciphered a biochemical mechanism that ensures that newly formed proteins are processed correctly when they leave the cell's own protein factories. This solves a decade-old puzzle in protein sorting.

In most cancers, it is not the growth of the primary tumor that determines the prognosis for the patient, but whether it will spread and form metastases. This process is very complex. There are often years between the development of the cancer and the aggressive growth of the metastases. Scientists from the DKFZ, the HI-STEM, the Ruhr University Bochum, Helmholtz Munich and ETH Zurich have studied and identified metastasis growth in breast cancer

Reduced immunosuppression possible in transplantations - 05/06/2023

Modified immune cells produce donor-specific tolerance

Traditionally, transplant recipients have had to take immunosuppressive medication for life to prevent organ rejection. However, there are considerable side effects involved. Using modified immune cells (MICs), TolerogenixX GmbH from Heidelberg has now managed to generate donor-specific tolerance in recipients of living kidney transplants without suppressing the overall immune system.

Inflammatory fatty liver disease (NASH, non alcoholic steatohepatitis ) and the resulting liver cancer are driven by autoaggressive T cells. Scientists from the German Cancer Research Center (DKFZ) now show what ist behind this destructive behavior. In both mice and humans with NASH, they found increased numbers of activated B cells in the gastrointestinal tract.

Volkswagen Foundation to fund international research project with around 1.5 million euros. Interdisciplinary team led by the Institute for Global Health at Heidelberg University Hospital to research the transmission of pathogens from animals to humans in Thailand and Laos. Long-term goal is to develop sustainable preventive measures against future pandemics.

Bacteria of the species Pseudomonas aeruginosa are antibiotic-resistant hospital germs that can enter blood, lungs and other tissues through wounds and cause life-threatening infections. In a joint project, researchers from the Universities of Freiburg and Strasbourg in France have discovered a mechanism that likely contributes to the severity of P. aeruginosa infections.

This month marks the launch of an outstanding project integrating artificial intelligence (AI) and neuromedicine – the Hertie Institute for Artificial Intelligence in Brain Health (Hertie AI). Founded on February 1 at the Medical Faculty of the University of Tübingen, it will be the first institute in Germany to research the prevention and early diagnosis of diseases of the nervous system using artificial intelligence methods.

Patients have 30 percent fewer serious side effects when medication doses are tailored to their genetic profile. This is what an international research consortium has found out, including the Dr. Margarete Fischer-Bosch Institute of Clinical Pharmacology at the Bosch Health Campus. With an individual DNA medication pass, as used in the study, treatments can be made more effective and safer in the future.

In the 2022 allocation round for the award of the prestigious Consolidator Grants of the European Research Council, researchers of Karlsruhe Institute of Technology (KIT) have been successful. For their projects in the fields of photovoltaics and medical sensor technology, physicist Ulrich W. 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.

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.

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.

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.
