Cell and gene therapies from bench to bedside

While cell therapy has become standard treatment for a number of blood cancers, most cell and gene therapy approaches for the treatment of hereditary and metabolic diseases, neurodegenerative disorders and cancer are still in the experimental phases or early clinical trials. However, recent successes give rise to the hope that cell and gene therapies will in future make important contributions to previously incurable diseases.

New drugs are intended to help stop viral zoonoses – infections that jump from animals to humans. To study suitable inhibitors, Prof. Dr Christian Klein from the Institute of Pharmacy and Molecular Biotechnology (IPMB) of Heidelberg University is receiving funding in the amount of 450,000 euros from the Volkswagen Foundation.

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.

During infections, the hematopoietic system switches from normal to emergency mode. This improves the defense against the pathogens. Scientists at the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) have now found an epigenetic switch in blood stem cells and progenitor cells of mice that can trigger the switch from one mode to the other.

University of Tübingen research team shortens the search for attackers that can wipe out multiresistant pathogens – with the aim of treating infections without antibiotics

Why do metastases often only appear after the original tumor has been surgically removed? Scientists from the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) and the Mannheim Medical Faculty of Heidelberg University have now published an explanation for this phenomenon. They were able to identify a messenger substance of the cancer cells that locally promotes the growth of the primary tumor.

Chronic myeloid leukemia (CML) is a type of blood cancer that arises from malignant changes in blood-forming cells of the bone marrow. It mainly occurs in older individuals and represents about 20 percent of all adult leukemia cases. A research team from the Institute of Molecular Medicine and Cell Research at the University of Freiburg has now demonstrated for the first time that mast cells play a crucial role in the development of CML.

Humboldt Research Award winner Prof. Hao Yan has been conducting research at the 2nd Institute of Physics at the University of Stuttgart since May. He is regarded as one of the world's leading experts in the field of DNA nanotechnology. "My work has many points of commonality with the topics that my colleagues in Stuttgart are focusing on," says Yan. "I have therefore been cooperating with Professor Laura Na Liu's working…

A new molecular engineering technique can precisely influence the development of organoids. Microbeads made of specifically folded DNA are used to release growth factors or other signal molecules inside the tissue structures. This gives rise to considerably more complex organoids that imitate the respective tissues much better and have a more realistic cell mix than before.

Germany's most important award for young scientists honors the development of immunotherapies against malignant brain tumors.

Viral zoonoses - 24/01/2022

Development of inhibitors that help stop viral zoonoses

Emerging viral infections such as COVID-19 or Zika disease pose an increasing threat to humans. At the Institute of Pharmacy and Molecular Biotechnology (IPMB) at Heidelberg University, Prof. Dr. Christian Klein's research group is developing inhibitors against already known viruses in the hope that these can also be used against new virus variants.

Induced pluripotent stem cells (iPSC) are suitable for discovering the genes that underly complex and also rare genetic diseases. Scientists from the German Cancer Research Center (DKFZ) and the European Molecular Biology Laboratory (EMBL), together with international partners, have studied genotype-phenotype relationships in iPSCs using data from approximately one thousand donors.

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.

Impaired function of lung fibroblast is considered causative for symptoms of the incurable lung disease COPD (Chronic Obstructive Pulmonary Disease). Using high-resolution epigenetic profiling, German and British scientists have now identified potential targets for COPD treatment. The team detected early epigenetic changes in the genome of COPD fibroblasts, providing new insights into the disease pathogenesis and potential therapeutic avenues.

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.

Team involving the University of Freiburg has developed a new analytical method for the basement membrane in human lungs.

Computer-assisted genome mining - 04/12/2023

Natural product genomics opens up new avenues in the search for antibiotics

Antibiotic-resistant pathogens are increasingly endangering our health. Since most of the drugs currently in use are based on secondary metabolites produced by bacteria or fungi, the research group of Prof. Dr. Nadine Ziemert in Tübingen is developing bioinformatic tools to specifically search the genome of these organisms for previously unknown antimicrobial agents.

In order to develop approaches for the prevention and treatment of Alzheimer's dementia in clinical trials, it would be helpful to be able to identify people with a particularly high risk of developing the disease. But which biomarkers can indicate an increased likelihood of disease early on in symptom-free people who actually develop Alzheimer's later?

HepaRegeniX GmbH, a clinical stage company developing a novel regenerative therapy for the treatment of acute and chronic liver diseases, announced the closing of a Series C round led by Vesalius Biocapital IV with participation of existing investors Novo Holdings, Boehringer Ingelheim Venture Fund (BIVF), and High-Tech Gründerfonds. The new funds of €15 million will be used to advance the clinical development of the clinical candidate HRX-215.

Personalized medicine with individually tailored therapies is becoming more a reality in cancer. This requires a look into the genetic material of tumors, a molecular diagnostic tumor profile. A research group from the German Network for Personalized Medicine (DNPM) has recorded the quality standards according to which genome analyses are carried out in Germany. The data is a prerequisite for integrating gene sequencing into routine care.

A guardian molecule ensures that liver cells do not lose their identity. The discovery is of great importance for cancer medicine because a change of identity of cells has come into focus as a fundamental principle of carcinogenesis for several years. The research team was able to show that the newly discovered guardian is so powerful that it can slow down highly potent cancer drivers and cause malignant liver tumors to regress in mice.
