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. ...
Protein and epigenetic biomarkers for variability in epidermal growth factor receptor inhibition in cancer treatment and characterization of the inhibitor-induced skin toxicity in an in vitro model
(2019-01-31)
Epidermal growth factor receptor (EGFR) is often over-expressed or over-activated in cells of solid tumors and can be targeted by specific inhibitors (EGFRIs), like erlotinib, gefitinib, cetuximab and panitumumab. ...
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 ......
RIG-I agonists as effective anti-viral prophylaxis and treatment in a mouse model of severe SARS-CoV-2 infection
(2022-07-08)
The recent outbreak of the COVID-19 pandemic highlights the need for novel prophylactic and therapeutic countermeasures against newly emerging viruses. Innate immune receptor agonists are considered to be a promising new ...
Dualsterische Liganden, allosterische Agonisten und ein allosterischer Förderer der Agonist-Bindung und -Funktion: Modellgestützte Analysen ihrer Rezeptorinteraktionen, Signalweg-Aktivierungen und -Selektivitäten an Wildtyp und punktmutierten hM1-Rezeptoren in CHO-Zellen
(2018-05-24)
Dualsterische Hybridliganden, bestehend aus einem allosterischen und einem orthosterischen Baustein, die über eine Zwischenkette verbundenen sind, gelten als ideale Werkzeuge zur Entwicklung subtyp- und signalwegselektiver ...
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 ...
Activation of the innate immune system by endoplasmic reticulum stress and proteasome inhibition
(2023-08-24)
The impact of proteotoxic stress on innate immune activation is currently unclear. Here, I investigated differential effects of ER stress and proteasome inhibition using genetically modified cell lines and primary human ...
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 ...
Contribution of SIGLEC-11 and SIGLEC-16 receptors to neuro-inflammation and neurodegeneration
(2023-02-14)
Brain aging is a multifactorial process including accumulation of aged lipids and proteins,
neuroinflammation and loss of neurons. SIGLEC-11 and SIGLEC-16 are paired opposite inhibitory- versus activatory-signaling ...
