Therapeutic viruses against tumours and metastases

Viruses can overcome cell barriers and transfer information to their host cells. They know how to make their host cell’s infrastructure work for them. This makes them excellent biotechnological tools, which a research group from the Fraunhofer IGB in Stuttgart is using to its advantage. The team is developing a therapeutic virus that not only recognises and fights tumours, but also has the potential to reach metastases.

Heidelberg University scientists are to receive three ERC Synergy Grants – three highly endowed grants of the European Research Council – for pioneering research projects by several teams working in collaboration.

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.

Cancer cells often grow in environments that are low in nutrients, and they cope with this challenge by switching their metabolism to using proteins as alternative "food". Building on genetic screens, an international team of scientists could identify the protein LYSET as part of a pathway that allows cancer cells to make this switch. Their findings are now published in the journal Science.

Imaging methods in medical diagnostics

Many different imaging methods are available these days and are used in almost all medical disciplines to visualise disease-related changes. Depending on the problem and the clinical picture, very different structural and functional parameters can be visually recorded for diagnosis and used for therapy.

Today, genome editing is almost as easy as programming software. However, the generation of viral vectors as initial material is still associated with many expensive and error-prone handling procedures. Viruses are generated via complex biological processes that have to be optimised virus-specifically in order to produce high-quality therapeutics. A new method is needed that simplifies and optimises these processes.

Metastatic breast cancer cells abuse macrophages, a type of immune cell, to promote the settlement of cancer metastases in the lungs. The reprogrammed macrophages stimulate blood vessel cells to secrete a cocktail of metastasis-promoting proteins that are part of the so-called metastatic niche.

Peptide-based COVID-19 vaccine - 21/04/2022

CoVac-1: T-cell activator against COVID-19

Current vaccines against COVID-19 aim at forming neutralising antibodies that prevent the virus from penetrating the host cells. Since people with impaired B-cell immune responses – which can also occur in cancer or autoimmune diseases – are not able to do this, researchers at the University of Tübingen have developed the peptide-based T-cell activator CoVac-1, which promises broad and long-term immunity.
