Apolipoprotein E4 is considered the most important genetic risk factor for Alzheimer’s disease. A group of researchers, led by MDC scientist Thomas Willnow, has now discovered how ApoE4 can damage the brain.

A research group at the MDC has discovered a protein that protects mature B lymphocytes from stress-induced cell death. It also helps immune cells produce effective antibodies, which can stop the pathogen at different points in the infection.

Setting out to identify all proteins that make up the sarcomere, the basic contractile unit of muscle cells, resulted in an unexpected revelation, providing experimental evidence that helps explain a fundamental mystery about how muscles work. The research was published in Nature Communications.

After more than 40 years, several teams at the MDC and ECRC have now made a breakthrough discovery with the help of two animal models: they have proven that an altered gene encoding the enzyme PDE3A causes an inherited form of high blood pressure. This could lead to new concepts for the treatment of hypertension.

Jan Philipp Junker creates cell lineage trees. He wants to understand the different paths that lead to a functioning organism. Perhaps one day, this knowledge will also reveal how organs are able to regenerate.

Researchers at the ECRC have successfully used RNA molecules to treat a dangerous pregnancy disorder called preeclampsia. They were able to alleviate common symptoms of the disorder, like maternal high blood pressure and fetal undernutrition, with virtually no side effects.

Two specific cell types in the nose have been identified as likely initial infection points for the novel coronavirus that causes COVID-19. Using data from the Human Cell Atlas, scientists discovered that goblet and ciliated cells in the nose have high levels of the entry proteins that SARS-CoV-2 uses to get into our cells.

Strategies for treating multiple sclerosis have so far focused primarily on T and B cells. A group of MDC researchers has now unveiled a new approach in Nature Immunology – one that seeks to increase treatment effectiveness by selectively targeting another type of immune cell called monocytes.

VRAC/LRRC8 chloride channels do not only play a decisive role in the transport of cytostatics, amino acids and neurotransmitters. They can also transport the important messenger substance cGAMP from cell to cell and thus strengthen the immune response to infections with DNA viruses.

Thomas Blankenstein receives an ERC Advanced grant for cancer research. The scientist wants to find out if T cells control the development of cancer by a process called immunosurveillance. For this purpose he now proposes a new research model.

In light of the pandemic, the Max Delbrück Center for Molecular Medicine (MDC) is pooling together its resources for projects that advance the understanding of SARS-CoV-2, while scaling down its regular research operations to a minimum. Here’s an overview of the MDC’s current collaborations and plans.

On Wednesday, 18 March 2020, 8 a.m., the Max Delbrück Center for Molecular Medicine in the Helmholtz Association (MDC) will go into emergency operation. Corona research will be intensified.

Perceiving warmth requires input from a surprising source: cool receptors. The finding published in Neuron by neuroscientists at the MDC challenges the theory that dedicated neurons convey either warm or cool sensations to the brain.

For the first time ever, researchers are looking at the molecular processes in the cell’s skeleton – the cytoskeleton – from a bird’s eye perspective. These processes are important for cell movement and cell shape formation. In Nature Cell Biology, an MDC team shows how cells coordinate such processes at the right place and time.

Researchers at the MDC have developed a new online tool that displays the development of the COVID-19 epidemic in Germany clearly and by individual state as well as worldwide. The map and timeline showing the spread of the coronavirus are freely available on the internet.

Biologist Holger Gerhardt studies how blood vessels form and grow. He is currently working with clinicians in Berlin to develop new methods for preventing and treating cardiovascular diseases and cancer.
