Immunzellen mit eingebauter Bremse / Das Molekül GPR83 kann Killerzellen zu Friedensstiftern machen

(PresseBox) (Braunschweig, )
Einem natürlichen Bremsmechanismus des Immunsystems sind Braunschweiger Forscher jetzt auf die Spur gekommen. Ein Molekül namens GPR83, so fanden Wissenschaftler der Gesellschaft für Biotechnologische Forschung
(GBF) heraus, kann überschießende Reaktionen der körpereigenen Abwehr rechtzeitig blockieren, bevor sie das eigene Gewebe schädigen. GPR83 erreicht das, indem es Abwehrzellen von einem aggressiven Zustand in einen friedfertigen "umschaltet". Störungen dieses Mechanismus könnten sowohl bei Autoimmunerkrankungen wie Rheuma oder Typ I-Diabetes als auch bei schweren Entzündungsreaktionen eine Rolle spielen. Ihre Erkenntnisse beschreiben die Wissenschaftler in der jüngsten Ausgabe der Fachzeitschrift Journal of Immunology.
