Young Investigator Award from the ESC - Dr. Mohammed Rabiul Hosen

August 29, 2021

YIA-RabiBig congratulations to our TRR259 member, Dr. Mohammed Rabiul Hosen!
Dr. Hosen received the Young Investigator Award (YIA) in Basic Science Session from the European Society of Cardiology (ESC) for the presentation of his latest translational work on ESC congress-2021, from August 27-30, 2021.


The study entitled “Circulating microRNA-122-5p correlates with improvement in left-ventricular function after transcatheter aortic valve replacement and regulates viability of cardiomyocytes via extracellular vesicles”.
Dr. Hosen with his group demonstrated that circulating miR-122-5p is upregulated via extracellular vesicles in aortic valve stenosis (AVS)-patients with persistent LV dysfunction after transcatheter aortic valve replacement (TAVR) and can be an important predictor of cardiac dysfunction in patients with low left ventricular ejection fraction (LVEF) after the TAVR procedure.


This study is funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) – Project-ID 397484323 – TRR 259 (Project B04).

App-based approach to treat heart disease

March 16, 2021

Felix Jansen's group shows how the collaboration between research institutions (Herzzentrum Bonn) and start-up companies (Vantis GmbH) can work to develop innovative treatment options for patients with coronary artery disease (CAD). They developed an app to integrate secondary prevention into the everyday life of patients with coronary artery diseases. The app provided a daily 15-minute program that included video-guided exercises, video sessions with background information about CAD, and a tool to record blood pressure and heart rate once a day. They could show that the regular use of the app appears to support lifestyle changes in patients with CAD.

Publication about an altered intercellular communication mediated by MicroRNA in chronic kidney diseases

November 02, 2020 

MicroRNA-mediated vascular intercellular communication is altered in chronic kidney disease

Chronic kidney disease (CKD) is an independent risk factor for the development of coronary artery disease (CAD). For both, CKD and CAD, the intercellular transfer of microRNAs (miR) through extracellular vesicles (EVs) is an important factor of disease development. Whether the combination of CAD and CKD affects endothelial function through cellular crosstalk of EV-incorporated miRs is still unknown.
The group of Andreas Zietzer et. al. could shown in this paper that EV-miR-mediated vascular intercellular communication is altered in patients with CAD and CKD, promoting CKD-induced endothelial dysfunction.

Publication about pulmonary hypertension associated with left-sided heart failure

 September 21, 2020

Pulmonary hypertension associated with left-sided heart failure

Pulmonary hypertension is a common phenomenon in heart failure patients that is highly relevant for morbidity and outcome. Although postcapillary in nature, the pathophysiology of pulmonary hypertension in patients with heart failure with reduced or preserved ejection fraction is complex, and decisions about management strategies remain challenging.

Recently, the hemodynamic definitions and subclassification of postcapillary pulmonary hypertension have been revisited. The distinction between isolated postcapillary pulmonary hypertension (IpcPH) and combined post and precapillary pulmonary hypertension (CpcPH) and their definition are essential. Novel data on the prognostic impact of hemodynamic variables and right ventricular function highlight the importance of cardiopulmonary interaction in patients with left-sided heart failure (LHF). Furthermore, the impact of management strategies including medical therapy, remote hemodynamic monitoring, and interventional approaches on hemodynamics and outcome has recently been investigated. Here, the group of Joana Adler et. al critically review recent developments and future considerations in this field, and highlight distinct treatment strategies targeting the underlying left heart condition, the pulmonary circulation, and/or impaired right ventricular function.

Publication about Nitro-fatty acids and their influence in ischemic ventricular arrhythmias

September 18, 2020

Nitro-fatty acids suppress ischemic ventricular arrhythmias by preserving calcium homeostasis

Nitro-fatty acids are electrophilic anti-inflammatory mediators which are generated during myocardial ischemic injury. Whether these species exert anti-arrhythmic effects in the acute phase of myocardial ischemia has not been investigated so far. The group of Martin Mollenhauer et. al demonstrate that pretreatment of mice with 9- and 10-nitro-octadec-9-enoic acid (nitro-oleic acid, NO2-OA) significantly reduced the susceptibility to develop acute ventricular tachycardia (VT). Accordingly, epicardial mapping revealed a markedly enhanced homogeneity in ventricular conduction. NO2-OA treatment of isolated cardiomyocytes lowered the number of spontaneous contractions upon adrenergic isoproterenol stimulation and nearly abolished ryanodine receptor type 2 (RyR2)-dependent sarcoplasmic Ca2+ leak. NO2-OA also significantly reduced RyR2-phosphorylation by inhibition of increased CaMKII activity. Thus, NO2-OA might be a novel pharmacological option for the prevention of VT development.

Publication about hnRNPU and its function 

July 02, 2020

The RNA-binding protein hnRNPU regulates the sorting of microRNA-30c-5p into large extracellular vesicles

The transfer of microRNAs (miRs) via extracellular vesicles (EVs) is a functionally relevant mechanism of intercellular communication that regulates both organ homoeostasis and disease development. Little is known about the packaging of miRs into EVs. Previous studies have shown that certain miRs are exported by RNA-binding proteins into small EVs, while for other miRs and for large EVs, in general, the export mechanisms remain unclear. Therefore, a proteomic analysis of endothelial cell-derived large EVs was performed, which revealed that heterogeneous nuclear ribonucleoprotein U (hnRNPU) is abundantly present in EVs. The specific role of hnRNPU for vesicular miR-sorting was confirmed independently by gain- and loss-of-function experiments.

In summary the group of Felix Jansen (AG Jansen), Zietzer and Hosen et. al. could show that hnRNPU retains miR-30c-5p and other miRs and thereby prevents their export into large EVs. The data presented provide a novel and functionally relevant mechanism of vesicular miR export.

Publication about MicroRNAs as master regulators of Atherosclerosis

June 8, 2020

MicroRNAs As Master Regulators of Atherosclerosis: From Pathogenesis to Novel Therapeutic Options

The Department of Internal Medicine II from the University Bonn published a new paper about microRNAs (miRNAs) as master regulators of atherosclerosis. Cardiovascular disease remains the major cause of morbidity and mortality worldwide. There are indications that atherosclerosis and its sequelae, coronary artery disease, contribute to the majority of cardiovascular death. It was shown that small RNAs, especially micro RNAs (miRNAs) are dynamic regulators of disease pathogenesis. They are considered to be central during the regulation of gene expression through numerous mechanisms and provide a means to develop biomarkers and therapeutic tools for the diagnosis and therapy of atherosclerosis. MiRNAs represent a valuable tool for diagnosing and monitoring of cardiovascular disease.
This paper will give an overview of the current developmental progression of RNA therapeutics as a holistic approach for treating cardiovascular diseases in different animal models and clinical trials. Future interrogations are warranted for the development of miRNA-based therapeutics to overcome challenges for the treatment of the disease

Publication about Hot spot 19F magnetic resonance imaging of inflammation 

May 07, 2020

Hot spot 19FHot spot 19F magnetic resonance imaging of inflammation

 

Among the preclinical molecular imaging approaches, lately fluorine (19F) magnetic resonance imaging (MRI) has garnered significant scientific interest in the biomedical research community, due to the unique properties of fluorinated materials and the 19F nucleus. Fluorine is an intrinsically sensitive nucleus for MRI—there is negligible endogenous 19F in the body and, thus, no background signal which allows the detection of fluorinated materials as “hot spots” by combined 1H/19F MRI and renders fluorine‐containing molecules as ideal tracers with high specificity. In addition, perfluorocarbons are a family of compounds that exhibit a very high fluorine payload and are biochemically as well as physiologically inert. Perfluorocarbon nanoemulsions (PFCs) are well known to be readily taken up by immunocompetent cells, which can be exploited for the unequivocal identification of inflammatory foci by tracking the recruitment of PFC‐loaded immune cells to affected tissues using 1H/19F MRI. The required 19F labeling of immune cells can be accomplished either ex vivo by PFC incubation of isolated endogenous immune cells followed by their re‐injection or by intravenous application of PFCs for in situ uptake by circulating immune cells. With both approaches, inflamed tissues can unambiguously be detected via background‐free 19F signals due to trafficking of PFC‐loaded immune cells to affected organs. To extend 19F MRI tracking beyond cells with phagocytic properties, the PFC surface can further be equipped with distinct ligands to generate specificity against epitopes and/or types of immune cells independent of phagocytosis. Recent developments also allow for concurrent detection of different PFCs with distinct spectral signatures allowing the simultaneous visualization of several targets, such as various immune cell subtypes labeled with these PFCs. Since ligands and targets can easily be adapted to a variety of problems, this approach provides a general and versatile platform for inflammation imaging which will strongly extend the frontiers of molecular MRI.

Publication about Thymic stromal lymphopoietin in atherogenesis 

April 13, 2020 

Thymic stromal lymphopoietin is a key cytokine for the immunomodulation of atherogenesis with Freund's adjuvant

Adaptive immune responses regulate the development of atherosclerosis, with a detrimental effect of type 1 but a protective role of type 2 immune responses. Immunization of Apolipoprotein E-deficient (ApoE−/−) mice with Freund's adjuvant inhibits the development of atherosclerosis. However, the underlying mechanisms are not fully understood.
Thymic stromal lymphopoietin (TSLP) is an IL7-like cytokine with essential impact on type 2 immune responses (Th2). Thymic stromal lymphopoietin is strongly expressed in epithelial cells of the skin, but also in various immune cells following appropriate stimulation.
The group of Martin Steinmetz investigated whether TSLP may be crucial for the anti-atherogenic effect of Freund's adjuvant. They found that subcutaneous injection of complete Freund's adjuvant (CFA) rapidly led to the expression of TSLP and IL1β at the site of injection.

Publication about Aortic Valve Stenosis in ATVB  

March 12, 2020 

Aortic Valve Stenosis – From Basic Mechanisms to Novel Therapeutic Targets

Aortic valve stenosis (AVS) is the most common acquired heart valve disease in the western world. The morbidity and mortality associated with AVS is tremendous and the 2-year mortality rate is around 50%. A complex process of endothelial dysfunction, immune cell infiltration, myofibroblastic and osteoblastic differentiation and subsequently calcification leads to remodeling and thickening of the aortic valve cups. The changes results in valve obstruction. The underlying pathophysiology of calcification are still unclear and no pharmacotherapy has been established to prevent aortic valve calcification. This review summarizes the current knowledge of pathomechanisms involved in aortic valve calcification and points out novel treatment strategies.
