In the brain of adult mammals neural stem cells ensure that new nerve cells, i.e. neurons, are constantly formed. This process, known as adult neurogenesis, helps mice maintain their sense of smell. A research team led by Dr Francesca Ciccolini at the Interdisciplinary Center for Neurosciences (IZN) of Heidelberg University recently discovered a second stem cell population in the mouse brain.

Although just cute little creatures at first glance, the microscopic geckos and octopuses fabricated by 3D laser printing in the molecular engineering labs at Heidelberg University could open up new opportunities in fields such as microrobotics or biomedicine. The printed microstructures are made from novel materials – known as smart polymers – whose size and mechanical properties can be tuned on demand and with high precision.

Screening trials for the early detection of rare diseases often fail due to insufficient predictive power of the results. For the rare HPV-related cancer of the pharynx, scientists from the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) now relied on the combined detection of antibodies against two different viral proteins in a proof-of concept trial.

The great potential of blood-based microRNA analyses

"The early bird catches the worm", is an apt description of what motivates Hummingbird Diagnostics GmbH from Heidelberg. The medium-sized biotechnology company analyses special biomarkers in blood, so-called microRNAs, in order to diagnose diseases at an early stage and to be able to make forecasts about the course of the disease and the success of therapy.

With its "Proof of Concept" grants, the European Research Council ERC supports scientists in further developing the commercial potential of their research results. Nina Papavasiliou from the DKFZ is now receiving the prestigious grant for the second time: she wants to advance the development of a "molecular delivery service" that ensures that therapeutic genes reach the right address in the body in a targeted manner.

Because of their highly active metabolism, many tumors are susceptible to a special type of cell death, ferroptosis. Nevertheless, cancer cells often manage to escape this fate. Scientists at the German Cancer Research Center have now discovered a new mechanism by which normal as well as cancer cells protect themselves against ferroptosis.

Theranostics of prostate cancer: the combination of radionuclide diagnostics and radionuclide therapy

Using a low-level radiopharmaceutical that binds to the prostate-specific membrane antigen (PSMA), positron emission tomography/computed tomography can be used to visualise even small prostate cancer metastases. Developed by Heidelberg researchers, the radiopharmaceutical is a modified radionuclide diagnostic agent that has been coupled with a powerful emitter and used as a therapeutic tracer to irradiate and destroy cancer cells from within.
