The endophytic fungus Stemphylium globuliferum – secondary metabolites and biological activities
(2018-01-22)
Fungi are a tremendous source of pharmaceutically significant compounds, e.g. the life saving immunosuppressant drug mycophenolic acid. The current project focused on the investigation of the mold fungus Stemphylium ......
Investigation of Multipotent Neural Progenitor Cell to Oligodendrocyte Differentiation including the Transcriptional Activator Protein Pur-alpha by Quantitative Proteomics
(2019-02-26)
Oligodendrocytes are neuroglial cells, localized in the white matter of the central nervous system. They develop from neural stem cells (NSCs), which produce, among others, migrating and proliferating oligodendrocyte ...
Funktionelle Untersuchungen des ABC-Transporters ABCG2
(2021-10-15)
Das Phänomen der Multidrug Resistance (MDR) stellt ein bedeutsames Problem bei der Behandlung von Tumoren mit Chemotherapeutika dar. Die ABC-Transporter ABCB1, ABCC1 und ABCG2 sind an der Entstehung der MDR beteiligt. ...
Charakterisierung des CPEB3 Ribozyms: Studien zur Aufklärung des Mechanismus eines humanen Ribozyms
(2019-03-27)
Kurze RNA Stränge mit enzymatischer Aktivität sind als Ribozyme bekannt. Das HDV-ähnliche CPEB3 Ribozym ist eine wenig erforschte selbstspaltende RNA. Es existiert in einer einzelnen hochkonservierten Kopie in der Sequenz ...
Formulierung von therapeutischen Oligonukleotiden mit PAMAM-Dendrimeren zur Aktivierung von Pattern Recognition Rezeptoren des angeborenen Immunsystems
(2019-05-03)
Der ubiquitär exprimierte Immunrezeptor Retinoic Acid inducible Gene-I, kurz RIG-I, ist eine zytosolisch lokalisierte Helikase, die zur Detektion von pathogenen RNA-Viren befähigt ist. Als synthetischer Ligand konnte eine ......
Synthesis, optimization, and characterization of chromen-4-one and 1,7-phenanthroline derivatives as ligands for the orphan G protein-coupled receptors 35 and 84
(2021-06-21)
G protein-coupled receptors (GPCRs) are ideal drug targets. Their characteristic tissue distribution, marked ligand specificity, and their roles in countless (patho)physiological processes are being exploited by more than ...
Investigating the ability of RIG-I agonists to provide protection in mouse and ferret models of respiratory virus infection
(2022-05-17)
Respiratory infections caused by influenza A virus (IAV) or respiratory syncytial virus (RSV) lead to substantial morbidity and mortality. Treatment options are limited and there is urgent need for the development of ......
Identification and pharmacological characterization of nucleotide pyrophosphatase/phosphodiesterase-1 (NPP1) and -4 (NPP4) inhibitors
(2022-07-29)
Ectonucleotidases are enzymes involved in different physiological functions and mainly in the regulation of purinergic signaling; in fact, they regulate the duration of purinergic receptor activation by catalyzing the ...
Inflammation-dependent differentiation of two distinct regulatory T cell populations in the visceral adipose tissue shapes systemic metabolism
(2023-12-07)
Visceral adipose tissue (VAT) is an endocrine organ critical for energy storage and metabolic homeostasis. It harbours a plethora of immune cells, which play an important role in maintaining tissue homeostasis. A large ...
Computational studies on δ-branch G protein-coupled P2Y and related orphan receptors
(2023-06-26)
G protein-coupled receptors (GPCRs) represent an attractive target for drug development as the modulation of their activity can induce a desired physiological response to treat pathological conditions. Given the knowledge ...
