The role of guanine nucleotide exchange factors (GEFs) in EGF-receptor signalling: Screening for a small molecule inhibitor of the Rin1-mediated Rab5 activation
(2018-06-04)
The small GTPase Rab5 is a key regulator of early endosomal trafficking. It functions as a molecular switch that can be activated by guanine nucleotide exchange factors (GEFs) and inactivated via hydrolysis of GTP with the ...
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. ...
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 ...
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 ...
Functional characterization of Gαi/s proteins and modulation of their activity by linear and cyclic peptides
(2024-01-30)
Heterotrimeric Gαβγ (guanine nucleotide-binding) proteins serve as molecular switches to activate (“switch on”) or inactivate (“switch off”) diverse intracellular signaling cascades in response to stimulated G protein-coupled ...
Control of pulmonary immunity by physical exercise
(2024-03-06)
Sedentary lifestyles combined with high caloric nutrition are widely known to severely contribute to the rise of metabolic diseases like diabetes, atherosclerosis, or obesity in recent years. While endurance training has ......
