Vascular Biology – PI: Jürgen Bernhagen

We are interested in the molecular and cellular mechanisms of cardiovascular disease and inflammation. A focus is on the role of atypical chemokines, inflammatory signaling pathways, and leukocyte recruitment processes in atherosclerosis, a chronic inflammatory condition of arterial vessels and the main underlying condition of ischemic stroke. We study these mechanisms from basic vascular biology to clinical translation.

We have discovered the cytokine MIF in inflammatory and vascular disease and have characterized it as a protagonistic member of the class of ‘atypical chemokines’. Relying on biochemical and vascular biology methodologies in combination with transgenic mouse models and clinical approaches, we broadly study the MIF protein family (i.e. MIF, MIF-2/D-DT, CXCR2, CXCR4, CXCR7, CD74, sCD74) and related classical chemokines in atherosclerosis, ischemic stroke, and myocardial infarction. This involves deciphering the receptor complexes and pathways driving atherogenic recruitment of leukocyte sub-populations, but we also focus on site- and disease-specific oxidized iso-forms as encountered under ischemic/oxidative stress as well as on chemokine-like alarmins such as HMGB1.

Another focus is on atheroprotective signaling pathways maintained by the COP9 signalosome (CSN) in atherogenic endothelium. The CSN is a multi-functional protein complex that regulates SCF cullin-RING E3-ligase (CRL) NEDDylation status, controlling ubiquitin/26S-proteasome-mediated degradation of cell-regulatory proteins. Based on our discovery of a link between CSN5/JAB1 and inflammation, we currently study atheroprotective effects of CSN5 via NFκB signaling.

We are also interested in cardioprotective mechanisms of some of these mediators and how they compare with corresponding effects in ischemic stroke and cerebral-/(micro)vascular pathogenesis but also other inflammatory diseases. Lastly, capitalizing on various collaborations, we increasingly pursue links between inflammation and neurodegeneration, i.e. inflammasome and amyloid/chaperone-type mechanisms.

Dr. Omar El Bounkari, Senior staff scientist & Technical laboratory head

Following my Biochemistry studies at the University of Hannover, I pursued my PhD degree at the Institute of Biochemistry at the Medical School of Hannover (MHH) under the supervision of Prof. Tamura-Niemann focusing on the interplay between tyrosine kinase signaling and the mRNA export machinery (THO complex). After a brief postdoc fellowship in the same group, I joined the lab of Prof. Bernhagen at RWTH Aachen University in 2010 first as a post-doc and then junior group leader, focusing on the characterization of heteromeric cytokine¬/chemokine receptor complexes MIF proteins, and their function in immune and inflammatory diseases. I followed the lab when it moved to LMU Munich in the end of 2015, where I am now a senior staff scientist, junior group, leader, and technical laboratory head. My research aims at decrypting the role of the MIF protein family and their receptors in immune cells, in particular B lymphocytes, and the related mechanisms that drive inflammatory processes in cardiovascular or autoimmune disease. In my leisure time, I like horse riding and hiking.

Grown up east of Cologne, Germany, he is a biochemist and immunologist by training, who obtained his Diploma (Master) degree and PhD from the University of Tübingen, Germany, and the Picower Institute for Medical Research, Manhasset, NY, USA.

He previously held positions in basic and applied biomedical research as a Postdoc and Senior Scientist at the Picower Institute for Medical Research, where he worked with Professors Richard Bucala and Anthony Cerami, and as a Group Leader and Department Head at the University of Stuttgart and the Fraunhofer Institute in Stuttgart. Before moving to Munich, he was a Professor of Biochemistry at RWTH Aachen University, where he headed the Institute of Biochemistry and Molecular Cell Biology.

His research centers around the molecular and cellular mechanisms driving inflammation and cardiovascular disease with a focus on cytokines, chemokines, their receptors, and cellular signaling platforms. He (re)-discovered MIF proteins, showing that they are central players in inflammatory pathologies, and identified the MIF/chemokine receptor axis as a driving force of atherosclerotic disease. The larger MIF family of proteins and their receptors as well as the COP9 signalosome continue to be a major focus in the lab due to their unique molecular properties and key position in cell physiology and disease processes including atherosclerosis and ischemic stroke.

Jürgen published >185 papers in this area, and his work has been cited >13000 times and is flanked by numerous patents. The research has been funded by the Deutsche Forschungsgemeinschaft (DFG), several Foundations, the SyNergy Excellence Cluster, the BMBF and Fraunhofer, the Munich Heart Alliance, and industry.

Jelena Milic received a prestigious fellowship (“Promotionsstipendium”) from Studienstiftung des deutschen Volkes.

July 2020 – Studienstiftung is Germany's oldest and most prestigious scholarship foundation. It awards fellowships to outstanding and particularly motivated doctoral students with distinguished personalities and well above-average degrees and scientifically excellent dissertation projects. Studienstiftung awards go to less than 0.5% of students pursuing their studies or doctoral projects in Germany. Jelena received the fellowship to pursue her doctoral thesis project on “The role of the COP9 signalosome in atherosclerosis”. Congratulations, Jelena, for receiving this fellowship award, best of success for your doctoral thesis, and enjoy the interactions with the other fellows at Studienstiftung’s wonderful academic program.

Young Investigator Award goes to Jelena Milic from Bernhagen Lab

March 2020 – Jelena Milic won the Gotthard Schettler Young Investigator Award at the Vascular Medicine and Atherosclerosis Conference (VMAC), held in Augsburg, 12-13th March, 2020. VMAC is organized by several leading German societies focusing on atherosclerosis and its sequelae, i.e. DGAF, DACH, and DGFF, as well as Working Group 41 (Atherosclerosis) of the German Cardiac Society (DGK). Jelena received the award for her lecture on “The Role of the COP9 Signalosome in Atherosclerosis” that she gave in the “Basic science – Young Investigator Award Session” of the VMAC conference. Congratulations, Jelena, for this very nice recognition of your research findings!

Feb 2020 – The BernhagenLab recently discovered that plant MIF proteins surprisingly have MIF-like chemokine activity. Dzmitry is the first author on this paper and did a great job in highlighting the X-Kingdom activity of MIF proteins with implications for both basics research (e.g. evolution of the innate immune system, structure-activity relationships of MIF/receptor interactions) to unexpected translational opportunities (e.g. smart foods or immune modulation). The paper is a collaborators with researchers from Aachen University and the University of Groningen, NL, and was published in the Journal of Biological Chemistry

Sinitski et al, JBC 2020; J Biol Chem. 2020 Jan 17;295(3):850-867.

and highlighted in Science Signaling

In collaboration with research from Zürich University and Yale University, we demonstrate a differential regulation of macrophage activation by the MIF cytokine superfamily members MIF and MIF-2 in adipose tissue during endotoxemia.

This study was just published in the FASEB Journal (Kim et al, FASEB J 2020; )

A novel link between the chemokine MIF and B lymphocytes in atherosclerosis

Mar 2018 – The Bernhagen lab uncovered a previously unrecognized connection between the atherogenic chemokine-like cytokine MIF and B cell function in atherosclerosis. Previously already implicated in controlling monocyte and T cell recruitment in atherogenesis, the current study (Schmitz et al., FASEB J. 2018) using an atherogenic ApoE-/- mouse model suggests that MIF also controls pro-atherogenic B cell activities in this disease. Mif-deficient mice which are protected from lesion development have a B cell development defect and exhibit atheroprotective natural IgM-containing antibody profile. The mechanism of generation of these anti-oxidized LDL antibodies needs to be explored in future work, the current study also supports recent evidence on a critical role for B cells in atherosclerosis. The study was conducted in collaboration with researchers from the Institute of Cardiovascular Prevention (IPEK) at LMU, RWTH Aachen University, the Peptide Biochemistry lab at WZW/TUM, Yale University, and the University of Düsseldorf.

A second paper by the same lab gave further mechanistic insight into how MIF regulates the receptor expression on B cell. Omar El Bounkari and his team unveil a connection between the pro-proliferative activity of MIF/CD74 signaling in B cells and inflammation (Klasen et al., Cell Signal 2018) uThis study was performed in collaboration with RWTH Aachen University and the Peptide Biochemistry lab at WZW/TUM.
