Dr. Dr. Karin Ziegler won the Fritz Külz Preis at the 9th German Pharm-Tox Summit. The Fritz-Külz Prize is awarded every two years by the German Society for Experimental and Clinical Pharmacology and Toxicology (DGPT) and is the DGPT's highest award for young scientiests.
Sarah Hölzl won the poster prize at the 2024 Annual Meeting of the German Society of Pharmacology and Toxicology for her Poster on “Elucidating missing X factors to understand sex bias in cardiovascular disease”.
November 2023
Daniel Andergassen, an independent Junior Group Leader at the Institute of Pharmacology and Toxicology at TU Munich, has been awarded a prestigious Starting Grant from the European Research Council (ERC). This grant will support an ambitious research program focused on understanding the molecular mechanism behind sex differences observed in heart failure. A specific emphasis will be on genes that escape X chromosome inactivation in females, resulting in a higher gene dosage compared to males. This fundamental research will deepen our understanding of the molecular mechanisms underlying sex bias in heart failure and aims to develop RNA-based therapies for sex-specific treatments.

Dr. Karin Ziegler won the August Wilhelm and Lieselotte Becht Forschungspreis 2023 for outstanding research work in the field of patient-oriented cardiovascular research at the DGK Herztage.

Trimannose-coupled antimiR-21 for macrophage-targeted inhalation treatment of acute inflammatory lung damage
Recent studies of severe acute inflammatory lung disease including COVID-19 identify macrophages to drive pulmonary hyperinflammation and long-term damage such as fibrosis. Here, we report on the development of a first-in-class, carbohydrate-coupled inhibitor of microRNA-21 (RCS-21), as a therapeutic means against pulmonary hyperinflammation and fibrosis. MicroRNA-21 is among the strongest upregulated microRNAs in human COVID-19 and in mice with acute inflammatory lung damage, and it is the strongest expressed microRNA in pulmonary macrophages. Chemical linkage of a microRNA-21 inhibitor to trimannose achieves rapid and specific delivery to macrophages upon inhalation in mice. RCS-21 reverses pathological activation of macrophages and prevents pulmonary dysfunction and fibrosis after acute lung damage in mice. In human lung tissue infected with SARS-CoV-2 ex vivo, RCS-21 effectively prevents the exaggerated inflammatory response. Our data imply trimannose-coupling for effective and selective delivery of inhaled oligonucleotides to pulmonary macrophages and report on a first mannose-coupled candidate therapeutic for COVID-19.

Cause of sleep disturbance in cardiac disease identified
Immune-mediated denervation of the pineal gland underlies sleep disturbance in cardiac disease. Ziegler et al., 2023.
A team led by Professor Stefan Engelhardt, head of the Department of Pharmacology and Toxicology at the Technical University of Munich (TUM), and first author Karin A. Ziegler has now identified a direct consequence of sleep disorders in patients with cardiovascular disease.
Around one third of people with heart disease suffer from sleep problems. In a paper published in the journal Science, a team at the Technical University of Munich (TUM) shows that heart diseases affect the production of the sleep hormone melatonin in the pineal gland. The link between the two organs is a ganglion in the neck region. The study demonstrates a previously unknown role of ganglia and points to possible treatments.

New DZHK junior research group leader follows trail of "escaped" genes
Many diseases progress differently in women and men. There are often differences in the way they develop. This also applies to cardiovascular diseases. The reason for this is not yet clear. Dr. Daniel Andergassen suspects that part of the answer lies in the sex chromosomes. With his own junior research group, which is funded by the DZHK, he wants to pursue his assumption over the next six years at the Technical University of Munich (TUM).

Ministry promotes development of Covid-19 drug: A spray against lung damage in Corona
rnatics, a start-up at the Technical University of Munich (TUM), has developed an RNA-based agent to prevent inflammatory lung damage. These occur particularly in severe corona processes. The German Federal Ministry of Education and Research (BMBF) is supporting further development of the drug with around 7 million euros. The rnatics team is focusing on a substance that blocks proinflammatory microRNA.

Epigenetic mechanisms for parent-specific genetic activation decoded - Unmuting the genome
Hereditary diseases as well as cancers and cardiovascular diseases may be associated with a phenomenon known as genomic imprinting, in which only the maternally or paternally inherited gene is active. An international research team involving scientists at the Technical University of Munich (TUM), the Max Planck Institute for Molecular Genetics (MPIMG) in Berlin and Harvard University in Cambridge (USA) has now investigated the mechanisms responsible for the deactivation of the genes.

A small RNA allows for therapeutic modulation of cardiac arrhythmias
Dena Esfandyari and colleagues discovered a crucial role of microRNA-365 (miR-365) in regulating human cardiac action potential. An abnormal cardiac action potential may lead to different types of life-threatening arrhythmias. This study suggests that miR-365 normalizes the pathologically altered action potential by modulating key cardiac repolarizing channels. These findings have been recently published in Nature Communications(link is external).

A macrophage small RNA promotes cardiac fibrosis
Deepak Ramanujam and Anna Patricia Schön from the IPT have hitherto discovered a previously unknown molecular function of microRNA-21 (miR-21) that promotes fibrosis through its action in macrophages. This study suggests that macrophages hold promise as target cells for RNA-based therapy against miR-21. These findings have recently been published in the #1 Cardiovascular Journal Circulation(link is external).

Inhalation spray agains pulmonary fibrosis after COVID-19
Patients who have had Covid-19 often suffer from reduced lung function for a long time afterwards. One cause of this is scarring of the lung tissue, known as pulmonary fibrosis. A small endogenous RNA molecule, microRNA, is suspected of driving this disease process. Synthetically produced inhibitors (anti-miR oligonucleotides) that neutralize microRNA would be a promising therapeutic strategy. However, when administered intravenously, the drug often does not reach the cells of the organ in question. In the case of the lung, the affected cells can be reached directly by inhalation.
The aim of the "Anti-miR against Pulmonary Fibrosis" project, headed by Stefan Engelhardt, Professor of Pharmacology and Toxicology at TUM, is to develop an inhalation method with the project partner Isar Bioscience GmbH, with which locally high drug concentrations can be achieved in the lungs. This should prevent the development of pulmonary fibrosis as a consequence of covid-19 disease.

Next step towards RNA-based therapy of heart failure:
In a collaborative effort, Rabea Hinkel (MRI TUM) and Deepak Ramanujan from the IPT successfully demonstrated the efficacy of synthetic inhibitors of microRNA miR-21 in a pig model for myocardial ischemia. Recapitulating the situation in human patients where, after myocardial infarction, dysregulation of microRNAs contributes to pathologic cardiac hypertrophy and fibrosis, they showed that inhibition of miR-21 significantly ameliorates the phenotype. Their publication in JACC, entitled „AntimiR-21 Prevents Myocardial Dysfunction in a Pig Model of Ischemia/Reperfusion Injury“, was selected as the Paper of the Month by the German center for Cardiovascular Research (DZHK).
