Until now, doctors knew hepatic stellate cells mainly as drivers of liver fibrosis. The actual functions have hardly been studied to date. Researchers from the German Cancer Research Center, the Mannheim Medical Faculty and Columbia University have now published that hepatic stellate cells control liver metabolism as well as liver regeneration and size. The results of the study could contribute to new therapeutic approaches for liver diseases.

Donating blood saves lives – but what long-term effects does this practice have on our bodies? Researchers from the German Cancer Research Center (DKFZ), the HI-STEM stem cell institute* and the German Red Cross Blood Donor Service, among others, have now discovered that frequent blood donations cause genetic adaptations in blood stem cells that promote the regeneration of blood cells.

Researchers have developed a new method that enables a more precise analysis of individual tumor cells circulating in the blood. This allows not only the previously possible genomic investigation of such tumor cells, but also the focused analysis of single-cell signaling pathways at the functional protein level. The combined analysis of the mutated genome and signaling proteins opens up new avenues for more targeted treatment methods.

Researchers have introduced an algorithm based on deep learning that can predict the effects of rare genetic variants.

With mice, researchers showed that experimentally induced lack of blood flow in the brain epigenetically reprograms astrocytes into brain stem cells, which in turn can give rise to nerve progenitor cells. This discovery shows that astrocytes could potentially be used in regenerative medicine to replace damaged nerve cells.

Encouraging results from a large international study led by Heidelberg have recently been published in the journal “Lancet”: The genetic material of cancer cells with unknown tissue of origin contains numerous targets for specific drugs that are already available and have been developed to treat other forms of cancer. These suppressed the disease in CUP patients for significantly longer than chemotherapy.

Innovation in emergency medicine - 23/05/2024

CARL pushes back the boundaries of resuscitation therapy

Few people survive a cardiac arrest; blood stops flowing to the brain and other vital organs and the resulting lack of oxygen causes extensive damage to the body. In response to this, researchers at the University Medical Centre Freiburg and Resuscitec GmbH have developed CARL, an innovative resuscitation system, which – in addition to the oxygen level – adjusts numerous blood parameters to individual patient requirements. This greatly improves…

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.

Fatty liver disease often leads to chronic liver inflammation and can even result in liver cancer. Scientists from the German Cancer Research Center (DKFZ) and the University of Tuebingen have now shown in mice that intermittent fasting can halt this development.

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.

An unexpected discovery surprised a scientist at the Max Planck Institute for Intelligent Systems in Stuttgart: nanometer-sized diamond particles, which were intended for a completely different purpose, shone brightly in a magnetic resonance imaging experiment – much brighter than the actual contrast agent, the heavy metal gadolinium.

Others leave the blood vessel and may then enter a long period of dormancy. What determines which path the cancer cells take is their epigenetic status.

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.

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.
