An international research team involving the universities of Paraná and Tübingen has developed a rapid test that can reliably identify Covid-19 antibodies in the blood within minutes. As the researchers report in the journal ACS Sensors, the new process is based on a simple measuring principle making it easy to carry out without expensive instruments, and is therefore suitable for use at mobile testing centers or by laboratories.

Known as the power plant of the cell, mitochondria are essential to human metabolism. Human mitochondria consist of 1,300 different proteins and two fatty biomembranes. The vast majority of mitochondrial proteins are produced with a cleavable transport signal and have to be actively transported into the mitochondria.

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.

As cancer progresses, the tumor cells continually change, ultimately resulting in a tumor consisting of a large number of different cell clones with different characteristics. This is referred to as "tumor heterogeneity". In many cases, the cancer cells become resistant to the treatments available.

Apogenix, a biopharmaceutical company developing next generation immunotherapeutics, announced today that asunercept showed statistically significant benefits for hospitalized COVID-19 patients in the ASUNCTIS trial. The open-label multi-center phase II trial investigated efficacy and safety of asunercept in 435 patients with moderate to severe COVID-19 disease.

Doctors and scientists from the German Cancer Research Center (DKFZ) and from Heidelberg University's Medical Faculty Mannheim have successfully tested a neoantigen-specific transgenic immune cell therapy for malignant brain tumors for the first time using an experimental model in mice.

In multiple myeloma, a cancer of the bone marrow, relapse almost always occurs after treatment. Initially, most patients respond well to therapy. However, as the disease progresses, resistant cancer cells spread in the bone marrow, with fatal consequences for the patients.

Which neurons in the brain mediate fear responses - and how do they flip the switch when the danger is over? The research team of Prof. Ingrid Ehrlich at the Institute of Biomaterials and Biomolecular Systems (IBBS), Department of Neurobiology studies these questions. Their latest results obtained in collaboration with scientists at the Friedrich Miescher Institute in Basel (Switzerland), the National Institute of Health (USA), and Innsbruck…

A pioneering technique developed by the Prevedel Group at EMBL allows neuroscientists to observe live neurons deep inside the brain – or any other cell hidden within an opaque tissue. The technique is based on two state-of-the-art microscopy methods, three-photon microscopy and adaptive optics. The paper reporting on this advancement was published on 30th September 2021 in Nature Methods.

Neuroblastoma can spread relentlessly or shrink spontaneously. Scientists from the Hopp Children’s Cancer Center Heidelberg (KiTZ), the German Cancer Research Center (DKFZ), the University of Heidelberg and the National Center for Tumor Diseases (NCT) Heidelberg have shown that some malignant neuroblastomas employ a trick to avoid cell death: they use a special mechanism to lengthen the telomeres at the end of their chromosomes.

Robots that move like ants, brain electrodes that alleviate symptoms of Parkinson’s, arm prostheses that can be controlled with pure thought power – over the last few years enormous progress has been made in the neurosciences and there has been an increasing shift from pure basic to applied research. There is a great deal of creativity in applied research in Baden-Württemberg. Nevertheless, basic research in the southwest of Germany has never…

Inflammatory fatty liver disease (NASH, non alcoholic steatohepatitis ) and the resulting liver cancer are driven by autoaggressive T cells. Scientists from the German Cancer Research Center (DKFZ) now show what ist behind this destructive behavior. In both mice and humans with NASH, they found increased numbers of activated B cells in the gastrointestinal tract.

Centromeres, the DNA sections often found at the center of the chromosomes, display enormous interspecies diversity, despite having the same vital role during cell division across almost the entire tree of life. An international team of researchers has discovered that the variation in centromere DNA regions can be strikingly large even within a single species. The findings, now published in the journal Nature, shed light on the molecular…

HITS researchers publish new findings on collagen, the most abundant protein in our body: So-called “sacrificial bonds” in collagen break faster than the basic structure and thus protect the tissue as a whole because they track down harmful radicals that are produced during mechanical stress. The work was published in “Nature Communications.”

A new network has been set up in Baden-Württemberg aimed at reducing animal experiments as well as further improving animal welfare. It combines new approaches and measures at the state’s biomedical research locations, which are expected to limit stress in laboratory animals and steadily reduce the number of animals used in research in line with the 3R principles of Replacement, Reduction, and Refinement.

COVIC-19 clinical trial - 07/04/2022

Convalescent plasma for COVID-19 therapy: clinical trial should bring clarity

Does it help to treat COVID-19 sufferers with antibodies from people who have recovered from the disease? It seems an obvious idea and has been tested thousands of times. However, there is not yet enough evidence to prove the clinical efficacy of treating COVID-19 patients with convalescent plasma. The transfusion physician Prof. Dr. Hubert Schrezenmeier from Ulm is planning to carry out a follow-up clinical trial to find the missing evidence.

Heidelberg scientists unveil genetic programmes controlling the development of cellular diversity in the cerebellum of humans and other mammals. The research results have now been published in the journal Nature.

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.

CureVac N.V. (Nasdaq: CVAC), a global biopharmaceutical company developing a new class of transformative medicines based on messenger ribonucleic acid (“mRNA”), today announced positive preliminary data from ongoing Phase 1 clinical programs in COVID-19 and seasonal flu, assessing both modified and unmodified mRNA technology. The tested vaccine candidates are being developed in collaboration with GSK.

Biochip systems - 02/09/2020

Miniature organs with great potential

Dr. Peter Loskill and his team at the Fraunhofer Institute in Stuttgart and the University Hospital of Tübingen are developing what is known as an "organ-on-a-chip" (OoC). An OoC is a microfluidic system that simulates small functional units of organ tissue. OoCs can be used in different ways: in basic and pharmaceutical research as well as in clinical research and application, where they might render many animal experiments…

During the growth and development of living organisms, different types of cells must come into contact with each other in order to form tissues and organs together. A small team working with Prof. Dr. Anne Classen of the Excellence Cluster CIBSS of the University of Freiburg has discovered that complex changes in form, or morphogenesis, during development are driven exclusively via the affinity of cells to each other.

On March 23, 2022, the U.S. Food and Drug Administration (FDA) granted approval to the first targeted radioligand therapy against metastatic prostate cancer based on a joint patent of the German Cancer Research Center (DKFZ) and the University of Heidelberg. The agent significantly improves the chances of survival for those affected.

Current diagnostic methods do not always reliably distinguish between chronic inflammation of the pancreas and pancreatic cancer. About one third of all diagnoses are inconclusive. Scientists from the German Cancer Research (DKFZ) and from Heidelberg University Hospital (UKHD) therefore searched for molecular markers that could specify this diagnosis.

Immunologists at Ulm University and its Medical Centre have developed a new model that could revolutionise the treatment of autoimmune disease as well as vaccine development. As 'Adaptive Tolerance' demonstrates, autoreactive antibodies are by no means disease drivers which a healthy organism swiftly eliminates. Rather, they trigger the formation of a class of antibodies that protect the body's own structures.
