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.

People with metabolic dysfunction-associated steatotic liver disease (MASLD) and more so with metabolic dysfunction-associated steatohepatitis and MASLD-associated hepatic fibrosis can progress to cirrhosis and hepatocellular carcinoma and are at increased risk of developing type 2 diabetes, cardiovascular and chronic kidney disease, and cancers. Future research might be beneficial for implementing precision medicine in MASLD.

Heidelberg scientist Dr Venera Weinhardt has received an ERC Synergy Grant for a pioneering biomedical research project. The European Research Council (ERC) is granting this funding to advance soft X-ray microscopy. This imaging technique along with other innovations will be used to investigate the hepatitis E virus.

In the current approval round of the German Research Foundation (DFG) Heidelberg University has been successful with six applications for grants to fund major, internationally visible research consortia. The six research consortia − three of them will reach the maximum funding length of twelve years after their extension − are to receive financial resources totalling nearly 87 million euros over a period of four years.

Immunotherapy using checkpoint inhibitors is effective in around a quarter of patients with liver cancer. However, to date, physicians have been unable to predict which patients would benefit from this type of treatment and which would not. Researchers from the German Cancer Research Center have now discovered that liver cancer caused by chronic inflammatory fatty liver disease does not respond to this treatment. On the contrary: in an…

Do BMMFs, the novel infectious agents found in dairy products and bovine sera, play a role in the development of colorectal cancer? Scientists led by Harald zur Hausen detected the pathogens in colorectal cancer patients in close proximity to tumors. The researchers show that the BMMFs trigger local chronic inflammation, which can cause mutations via activated oxygen molecules and thus promote cancer development in the long term.

In a so-called inactivated or killed vaccine, the virus particles it contains are first rendered inactive by means of the toxic chemical formaldehyde. A better way of achieving this, however, is to irradiate the pathogens with low-energy electrons. Four Fraunhofer Institutes have now developed a new method of vaccine production based on this technique that is not only quicker but also guarantees a higher quality of product.

Next generation vaccine production

For decades, conventional inactivated vaccines have been produced by killing pathogens with toxic chemicals. However, this process often changes the surface structure of the pathogens to such an extent that the immune system is only able to induce a weak response. KyooBe Tech GmbH is offering a method that uses low-energy electrons to inactivate pathogens. Vaccines produced this way are much higher quality, making them safer and more effective.

HepaRegeniX develops an active substance for liver regeneration

When the liver stops regenerating on its own, it might be possible in future for doctors to intervene with a chemical agent. Tübingen-based HepaRegeniX GmbH is developing a promising candidate with the aim of improving the treatment of both acute and chronic liver failure.

New pathogens in beef and cow's milk contributing to the risk of cancer

A team of researchers led by Nobel laureate Prof. Dr. med. Dr. h.c. mult. Harald zur Hausen has discovered a new type of infectious agent in dairy and meat products produced from European cattle that increases the risk for colon and breast cancer. These so-called Bovine Meat and Milk Factors (BMMFs) are small DNA molecules that are similar in sequence to both bacterial plasmids and certain viruses.

With molecular diagnostics to biomarker-based personalised therapy

Diagnosing suitable biomarkers is a prerequisite for tailoring personalised therapies to patient heterogeneity. Genetic tests and genome sequencing play a key role in these diagnoses. Up until now, personalised therapy has achieved the greatest success in the field of oncology. However, personalised treatments are also gaining in importance for treating other diseases.

Advances in the study and treatment of liver diseases

Liver diseases are often underestimated despite being quite common and potentially having serious and even life-threatening consequences, especially in chronic cases. The most common causes of liver diseases are hepatitis viruses, excessive alcohol consumption, and obesity; congenital or autoimmune liver diseases are quite rare. Thanks to advances in medical research, diseases such as hepatitis B and C can be treated effectively.

Data mining new opportunities for medicine and public health

Research and healthcare activities produce huge quantities of data that need to be presented in an understandable structure. This requires computer-assisted extraction of relevant data and the use of statistical methods. This process, known as data mining, enables the discovery of patterns in large data sets. Data mining methods are of particular importance in fields that use high-throughput, visualisation methods and telemedical applications.

RNA interference confidence is returning

The 15-year history of RNA interference is not short on dramatic effects. It begins with the unexpected discovery and publication of the process of post-transcriptional gene silencing in 1998 for which Andrew Fire and Craig Mello were awarded the Nobel Prize in Physiology or Medicine just eight years after their discovery. In 2001 Thomas Tuschl succeeded in switching off genes in human cells with small synthetic pieces of RNA siRNA.
