Individuals with a genetic predisposition to Alzheimer’s disease show altered blood levels indicating damaged neuronal contacts as early as 11 years before the expected onset of dementia symptoms. This is evident in the levels of the protein “beta-synuclein”. An international team report these findings in the journal “Alzheimer’s & Dementia”. The biomarker studied here could potentially help to detect neurodegeneration at an early stage.

While broad-spectrum antibiotics can offer protection against a wide variety of bacteria, there are currently no analogous clinically available broad-spectrum antiviral agents that can act on several different viruses.

Researchers of the University of Freiburg introduce biosensor for the nucleic acid amplification-free detection of SARS-CoV-2 RNA.

On the one hand, blood vessels supply tumors with nutrients and, on the other, enable cancer cells to spread throughout the body. The settlement of circulating tumor cells in a distant organ is promoted by factors whose production is induced by the primary tumor itself. Scientists have now identified a new growth factor produced by blood vessels that enables tumor cells to metastatically colonize organs.

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.

Zebrafish can completely replace damaged heart muscle cells: The affected organ becomes fully functional again. Researchers at Ulm University have discovered that a specific cell-to-cell communication signal helps them to cope better with replication stress. This stress inhibits tissue regeneration in humans and mammals as they age. In Zebrafish a signalling protein ensures that the cells of the damaged organ continue to divide and thus multiply.

EMBL scientists pave the way for reducing the harmful side effects antibiotics have on gut bacteria. Antibiotics help us to treat bacterial infections and save millions of lives each year. But they can also harm the helpful microbes residing in our gut, weakening one of our body’s first lines of defence against pathogens and compromising the multiple beneficial effects our microbiota has for our health.

Treatment resistance is a central problem in the treatment of cancer. Bone and soft tissue tumors – known as sarcomas – in adolescents and young adults often stop responding to treatment too. This is because cancer cells develop a large number of new characteristics as the disease progresses and often become resistant to drugs that were originally effective.

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?

Drugs consist of molecules developed in the drug laboratory that bind to their target, usually a protein, and thus exert their effect. The actual duration of binding of a drug molecule to its target protein varies depending on the drug. The lifetime of the drug-target complex can play a critical role in the efficacy of a drug, as a long residence time at the target can be crucial for the drug's action in some cases.

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.

Invasive infections such as sepsis require immediate and targeted treatment. Experts from the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB and group partners have succeeded in establishing a reconceptualized detection principle that can make a crucial contribution to saving lives through fast, ultra-accurate pathogen identification. They have been chosen to receive the 2024 Stifterverband Science Prize for their efforts.

An international research team involving the universities of Paraná and Tübingen has developed a rapid test that can reliably identify Covid-19 antibodies in the blood within minutes. As the researchers report in the journal ACS Sensors, the new process is based on a simple measuring principle making it easy to carry out without expensive instruments, and is therefore suitable for use at mobile testing centers or by laboratories.

As cancer progresses, the tumor cells continually change, ultimately resulting in a tumor consisting of a large number of different cell clones with different characteristics. This is referred to as "tumor heterogeneity". In many cases, the cancer cells become resistant to the treatments available.
