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.

Adult stem cells hope for regenerative therapies

Adult stem cells have the lifelong ability to generate new specialised cells. They secure the continuous replenishment of cells therefore enabling the constant replacement of dying cells with new ones. Progress in the characterisation isolation and specific differentiation of adult stem cells over recent years raises hopes for the future use of the cells in the therapy of degenerative diseases. Knowledge about adult stem cells also has the…

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.

Researchers have developed a promising cellular immunotherapy for the treatment of glioblastomas: They equipped T cells with a receptor that recognizes a protein of the brain tumors that is responsible for the dangerous stem cell properties. The therapeutic T cells directed against this target structure were able to specifically destroy human brain tumors in laboratory experiments and in mice.

Vaccination against oncogenic Epstein-Barr viruses

Almost all humans are infected with Epstein-Barr viruses (EBV), which are linked to the development of benign diseases such as infectious mononucleosis as well as several cancers. Scientists from the German Cancer Research Center have developed a new strategy for creating a vaccine that targets different EBV virus life phases and has the potential to provide effective protection against EBV infection.

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.

For the first time, scientists from the German Cancer Consortium (DKTK) partner site in Essen/Düsseldorf have discovered stem cells of the hematopoietic system in glioblastomas, the most aggressive form of brain tumor. These hematopoietic stem cells promote division of the cancer cells and at the same time suppress the immune response against the tumor.

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.

Systems biology understanding complex biological systems

Systems biology studies complex interactions within biological systems on the genome proteome and organelle level. Many techniques from the fields of systems theory and associated fields can be used to gain an understanding of the behaviour and biological mechanisms of cellular systems.

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.

The summer reception hosted by BioRegio STERN Management GmbH has once again provided a fitting backdrop for the Science2Start award ceremony. Last Thursday, at Tübingen observatory, was the 15th time that scientists and start-up founders were celebrated for outstanding ideas that a panel of experts judged to have special economic potential.
