Better immune response against prostate cancer thanks to new bispecific antibodies

TWYCE, a Tübingen-based start-up spun off from the German Cancer Research Center in Heidelberg and the Faculty of Medicine at the University of Tübingen, is focused on developing a combinatorial therapy using two bispecific antibodies from bench to clinical practice. The founders aim to introduce an effective strategy for combating solid tumours, with initial proof of concept targeted at prostate cancer.

With "OrgaPlexing", scientists at the MPI of Immunobiology and Epigenetics have developed a new method that shows how guardian cells of the immune system, the macrophages, orchestrate their cell structures during inflammation or bacterial infection, making it possible to observe the interactions between several organelles simultaneously and thus providing insights into cell metabolism and the production of inflammatory molecules.

The Baden-Württemberg Ministry of Science, Research and Arts (MWK) is supporting medical researchers at Ulm University with start-up funding totalling 600,000 euros. The aim is to establish an EU consortium for the broad therapeutic use of mesenchymal stromal cells. The funding is being awarded as part of the "BEGIN - Participation in major European projects and initiatives" programme.

How do tumors react to a certain therapeutic approach? Knowing this before the start of a therapy would be of enormous value for people suffering from cancer as well as for the doctors treating them. Researchers have now made this very observation possible for the CAR-T cell therapy. This allows us to individually investigate how exactly these tumor cells react to the planned therapy.

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.

Activated T cells that carry a certain marker protein on their surface are controlled by natural killer cells. In this way, the body presumably curbs destructive immune reactions. Researchers now discovered that NK cells can impair the effect of cancer therapies with immune checkpoint inhibitors in this way. They could also be responsible for the rapid decline of therapeutic CAR-T cells.

Cortisone and other related glucocorticoids are extremely effective at curbing excessive immune reactions. But previously, astonishingly little was known about how they exactly do that. A team of researchers from Charité – Universitätsmedizin Berlin, Uniklinikum Erlangen and Ulm University have now explored the molecular mechanism of action in greater detail.

Making a personalised T cell therapy for cancer patients currently takes at least six months; scientists at the German Cancer Research Center (DKFZ) and the University Medical Center Mannheim have shown that the laborious first step of identifying tumor-reactive T cell receptors for patients can be replaced with a machine learning classifier that halves this time.

Researchers at the Faculty of Medicine of the University of Freiburg discover key factor in the development of immune cells. New approaches for the treatment of ALPS.

Inflammation of the heart muscle, also known as myocarditis, is a serious consequence of a viral infection. This can impede the heart’s ability to pump blood in the long term. In a current study, researchers of the Faculty of Medicine of the University of Freiburg have discovered a new approach for treating myocarditis.

The progression of multiple sclerosis (MS) can usually be slowed down with medication, but a cure is currently not possible. It is now established that Epstein-Barr viruses are involved in the development of MS. However, it is not known how the pathogens trigger the disease.

Nanoparticles as drug carriers - 09/11/2023

Inhalation of nanocarriers for antibiotics against resistant tuberculosis pathogens

Around ten million people worldwide still contract tuberculosis every year. With an estimated 1.4 million deaths a year, tuberculosis was the world’s deadliest infectious disease until COVID-19. The high mortality rate is down to the sophisticated biology of the pathogen Mycobacterium tuberculosis. A team of researchers from the KIT and the Research Centre Borstel (FZB) has developed a method that aims to outsmart the bacterium once and for all.

Epigenetically active drugs enable the cell to read parts of the genome that were previously blocked and inaccessible. This leads to the formation of new mRNA transcripts and also new proteins, as scientists from the German Cancer Research Center and the University Hospital Tübingen have now published. These "therapy-induced epitopes" could help the immune system recognize cancer cells.
