Proteine steuern das Überleben von B-Lymphozyten

Forscher des Exzellenzclusters "bioss" der Universität Freiburg entdecken Komponente für das Überlebenssignal von Immunzellen

(PresseBox) (Freiburg, )
Forscher am Zentrum für biologische Signalstudien (bioss) der Albert-Ludwigs-Universität haben einen neuen Signalweg aufgedeckt, der das Überleben und die Differenzierung von B-Lymphozyten steuert. B-Lymphozyten sind ein Typ der Immunzellen. Die Studie, die diese Woche in der jüngsten Ausgabe der Wissenschaftszeitung "Nature Immonology" erscheint, zeigt, dass Transkriptionsfaktoren der FOXO-Familie wichtige Regulatoren des Überlebens- und Differenzierungsprogramms von B-Lymphozyten sind. Als Transkriptionsfaktoren binden FOXO-Proteine direkt an die DNA der Zelle und können dadurch bestimmte Gene an- oder ausschalten.

Der menschliche Körper besitzt über eine Billiarde B-Lymphozyten. Nach ihrer Aktivierung und Differenzierung zu Plasmazellen produzieren diese Zellen Antikörper, welche uns vor vielen Infektionen fnlwyowa.
