T cell lipid metabolism as an immune “checkpoint” in renal cell carcinoma.

Immune cells, such as T cells, are able to combat infections and cancer. This ability is critical for the success of cancer immunotherapy. However, an immune-dysfunction occurs in a large proportion of patients, leading to tumor progression; the mechanisms of this phenomenon are not sufficiently explored to date. Intact cellular metabolism is crucial for an effective immune response. In this project, we will study tumor infiltrating T cells and test if a T cell metabolic dysfunction contributes to impaired anti-tumor immunity.

Bonner Promotionskolleg "NeuroImmunology" (BonnNi)

Unser Wissen über die Funktion von Nerven- und Immunsystem befindet sich in einem rasanten Anstieg und viele große Volkskrankheiten beruhen auf einer wechselseitigen Fehlfunktion beider Systeme. Das Promotionskolleg NeuroImmunology trägt dem steigenden Bedarf an MedizinerInnen mit fundierter wissenschaftlicher Ausbildung Rechnung. Es basiert auf der intensiven Kooperation zweier führender DFG-geförderter Forschungsverbünde. Der SFB 1089 und das Exzellenzcluster ImmunoSensation stehen für wissenschaftliche Kernbereiche an unserem Campus.

Therapeutische Nutzung des programmierten Zelltods zur Lungenkrebsbehandlung

Durch den programmierten Zelltod, genannt Apoptose, können im Körper gezielt geschädigte und entartete Zellen entsorgt werden. Zudem zielen viele Krebsmedikamente auf Apoptoseauslösung in Tumorzellen. Für Lungenkrebszellen bedeutet die Verhinderung von Apoptose also einen Wachstumsvorteil. Seit Kurzem sind Medikamente verfügbar, die gezielt anti-apoptotische Proteine wie MCL1 und BCL2 blockieren. Therapeutisch könnten diese vor allem auch in Kombination mit verfügbaren Krebsmedikamenten relevant sein.

Circulating tumor DNA for noninvasive disease profiling and monitoring in patients with primary CNS lymphoma

Liquid Biopsy has evolved as a promising approach for noninvasive cancer detection and monitoring. Due to major technical advances in recent years, Liquid Biopsy technologies allow the sensitive and accurate identification of small tumor DNA fragments (circulating tumor DNA, ctDNA) in the blood of cancer patients.

Biologische Determinanten und neuronale Kompensationsmechanismen der Presbyphagie

Infolge biologischer Alterungsvorgänge und Erkrankungen stellen Schluckstörungen im Alter (Presbyphagien) ein medizinisch relevantes, kaum erforschtes Problem dar, für das profunde Behandlungsoptionen fehlen. In diesem Projekt werden Einflussfaktoren auf die Schluckfunktion im Alter wie Kognition, Gebrechlichkeit, Muskelschwund, Geruchs- und Geschmacksinn, Veränderungen biochemischer Signalkaskaden und der zentralnervösen Steuerung des Schluckaktes umfassend untersucht, sowie Folgen der Presbyphagie auf Lebensqualität, Ernährungsstatus und Krankenhausaufenthalte erfasst.

Boosting Twice: Systemische Immuneffekte nach Hochdosis-Bestrahlung von Glioblastomen

This research project tests an innovative approach, in which high radiation doses are focused to the tumor bed to elicit systemic effects against glioblastoma, a highly malignant brain tumor. This approach has now become feasible due to the availability of novel technology, such as low energy intraoperative radiotherapy and novel drugs, such as immune checkpoint inhibitors.

Dresden creates ground-breaking interface between technology and medicine

Representatives of the Else Kröner-Fresenius Foundation (EKFS), TU Dresden and the University Hospital Carl Gustav Carus Dresden signed the contract for the Else Kröner-Fresenius Center for Digital Health Dresden in the presence of the State Ministers for Research and Economics today (Wednesday, 4th September, 2019). Starting in September 2019, the foundation will provide a total of 40 million euro over ten years to support the establishment of innovative educational and organisational structures, interdisciplinary cooperation and the expansion of additional research resources.

Pleiotropic effects of Empagliflozin in human and mouse myocardium

Empagliflozin is an inhibitor of the sodium-dependent glucose co-transporter 2 (SGLT2) and is clinically approved as an oral antidiabetic drug. By inhibiting SGLT2 in the proximal tubule of the kidney, empagliflozin reduces the reuptake of glucose and sodium and thereby lowers blood glucose. In the EMPA-REG OUTCOME trial, empagliflozin was evaluated for its cardiovascular safety. The results showed that empagliflozin reduced cardiovascular mortality, all-cause mortality and heart failure hospitalization rates.

Identifying novel mechanisms for Huntington’s disease intervention by defining protein homeostasis of stem cells’

Alterations in 3D genome organization can cause human birth defects by disrupting the physical communication between genes and DNA sequences controlling their expression. However, these disease mechanisms can be difficult to study. With the support of the Else Kröner Fresenius Foundation, our laboratory has implemented a new experimental approach to investigate how changes in 3D genome organization can cause human disease.

Clinical and experimental evaluation of homoarginine in stroke treatment

Stroke is the second leading cause of death and major cause of disability worldwide. Recent epidemiological studies revealed that stroke and death rate are higher in people with low blood levels of the amino acid homoarginine. In experimental stroke models, homoarginine supplementation reduced stroke size and disability. Now we aim to normalize low homoarginine levels in stroke patients and we will evaluate clinical and vascular parameters after 6 months. Additional experimental studies will uncover potential underlying mechanisms.
