Abstract (German)

In dieser Arbeit wurde die Bedeutung einer Gαs-zu-Gαi-Signalumschaltung am β2-AR in synovialen Fibroblasten von RA-Patienten untersucht. Verglichen wurden die Signalwege in synovialen Fibroblasten von RA-Patienten mit Fibroblasten aus den inguinalen Lymphknoten von gesunden Kontrollen. Es konnte gezeigt werden, dass die Voraussetzungen für eine Gαs-zu-Gαi-Umschaltung durch gemeinsames Binden von ...

Translation of the abstract (English)

In this thesis, the relevance of a Gαs-to-Gαi switch at the β2-adrenergic receptor in synovial fibroblasts from RA patients was investigated. The signalling pathways in synovial fibroblasts from RA patients were compared with fibroblasts from inguinal lymph nodes of healthy controls. It was shown that the conditions for a Gαs-to-Gαi switch were met by common binding of β-arrestin and PDE4 to the ...
