Heart

Grizzly bears in hibernation or a pineapple in an MRI scanner – at the “Science Day” at the “Robert Havemann” high school in Berlin-Karow, researchers from the Max Delbrück Center presented students of grades 11 and 12 unusual facets of their research.

Unlike humans, zebrafish can completely regenerate their hearts after injury. They owe this ability to the interaction between their nervous and immune systems, as researchers led by Suphansa Sawamiphak from the Max Delbrück Center now report in the journal “Developmental Cell.”

When the PRDM16 gene mutates, heart muscle cells undergo changes in their metabolism. This increases the risk of congenital heart failure in women more than men, as a ECRC research team led by Sabine Klaassen and Jirko Kühnisch reports in “Cardiovascular Research.”

Science has something exploratory about it, says Norbert Hübner. You never know exactly where you are heading. Despite this, cartographic works are the focus of his interest: the researcher creates atlases of the human heart. And amongst other things, he uses them to understand heart conditions better.

On August 1, 2023, Sofia Forslund will take up a W3 Professorship in Applied Microbiology at Charité. She will continue her scientific work at the ECRC, which involves close collaboration with researchers from the Max Delbrück Center and Charité.

British and German scientists created the most comprehensive cell atlas of the human heart. As reported in the journal “Nature”, it is the first to include the cells from which the heartbeat originates. Among other things, this data will provide a reference for studies on cardiac arrhythmias.

The Max Delbrück Center in Berlin and Heidelberg University will found a new Helmholtz Institute for Translational AngioCardioScience (HI-TAC) in Mannheim and Heidelberg. The Helmholtz Senate voted in favor of the institute, which will integrate vascular biomedicine, systems biology and heart research.

Hypertension can damage the heart, brain, and blood vessels. The immune system plays an important role in this process, Suphansa Sawamiphak from the Max Delbrück Center reports in Cardiovascular Research. The study, using zebrafish, found that inflammation causes macrophages to damage blood vessels instead of protecting them.

To improve the diagnosis and treatment of cardiovascular diseases in the future, a European partnership is awarding more than five million euros to four international research teams. A project on the consequences of pulmonary hypertension, co-led by Gabriele G. Schiattarella, is also being funded.

They have their sights set on serious diseases: Gabriele G. Schiattarella analyzes mechanisms of heart failure, Simon Haas wants to improve immunotherapies for leukemia and Michael Sigal would like to prevent gastrointestinal diseases. Now, the ERC is awarding the researchers with a Starting Grant.
