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.

Sabrina Lukanovic, LL.M, Team assistant
After finishing my Bachelor studies in law, I was awarded a scholarship for Master studies in International Business Law at the Central European University (Hungary). Currently, I am the team assistant to Prof. Bernhagen and Dr. Gökce. When I am out of the office, I love to spend time with my two year old daughter.
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.

Jürgen was appointed Professor and Chair of Vascular Biology at LMU and Principal Investigator at ISD in 2015. 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.

Hypoxia chamber to mimic ischemic stress in cardiomyocytes, neuronal brain cultures, or endothelial cells
New papers of the BernhagenLab reveal a role for the MIF/CXCR2 axis in neutrophil survival and identify novel cyclic peptides that inhibit MIF/CXCR2: implications for targeting strategies in inflammatory diseases
Nov 2020 / Feb 2021 – While the recruitment role of MIF and its chemokine receptors in atherosclerotic inflammation has been well described for monocytes, little is known about neutrophils, the first cells to arrive at inflammatory sites. Lisa Schindler, Leon Zwissler, and Christine Krammer together with our collaborators at the University of Otago in Christchurch, NZ, and the West-German Heart Center in Essen, now identify a role for the MIF/CXCR2 axis in neutrophil survival, a process governing the balance between the amplification of the inflammatory response and its resolution. In a second paper, Christine Krammer from our lab, together with collaborators from the KapurniotuLab at TUM and colleagues from the Institute for Cardiovascular Prevention (IPEK) of LMU, RWTH Aachen University, and Carolus/Moderna Therapeutics, report on novel, proteolytically stable, cyclic peptides that can block the MIF/CXCR2 axis. The studies are published in the Journal of Leukocyte Biology and ChemBioChem.

Two papers of the BernhagenLab shed light on the evolution and differential roles of MIF proteins in inflammation with implications for basic mechanisms but also cardiovascular and inflammatory diseases
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; )

Oct 3-6.
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.
Dositej Obradović fellowship award
Nov 2017 – Jelena Milic, first year PhD student in the Bernhagen lab at ISD, was awarded the Dositej Oradovic scholarship.
