Eine bestimmte Sorte Zellen, die regulatorischen T-Zellen oder kurz Tregs, hat die Aufgabe, Immunreaktionen zu bremsen. Sie sind gewissermaßen die Verkehrspolizisten des Immunsystems. Wissenschaftler vom Helmholtz-Zentrum für Infektionsforschung (HZI) haben erforscht, wie die Tregs entstehen: Das Protein IκBNS spielt dabei die entscheidende Rolle. Mit diesem Wissen, so hoffen die Forscher, könnte man die Zahl der Tregs eines Tages vielleicht steuern - und so das Immunsystem gezielt bremsen oder "scharf schalten". Ihre Ergebnisse präsentieren die Wissenschaftler um den Biochemiker Prof. Ingo Schmitz in der Fachzeitschrift Immunity.
