Schutzmechanismus für störungsfreie Zell-Zell-Kommunikation entdeckt

Lypd6 reguliert als "Schalterprotein" die Aktivierung des Wnt-Signalweges

(PresseBox) (Ulm, )
Die Kommunikation zwischen Zellen ist für viele physiologische Prozesse essentiell. Eine zentrale Rolle dabei spielt die sogenannte Signalübertragung. Zellen können damit auf äußere "Reize" reagieren und diese als "Reizinformation" ins Zellinnere weitergeben, wo diese Informationen wiederum den Ausschlag geben, ob die Zelle sich teilt, sich weiter ausdifferenziert oder ihr Arbeitsprogramm ändert. Ein ganz besonderer Signalweg, der vor allem für die Embryonalentwicklung entscheidend ist, wird über so genannte Wnt-Proteine vermittelt. Diese Proteine docken an spezifische Rezeptoren in der Zellmembran an, die wiederum die Bindungsinformation als chemisches Signal ins Zellinnere weitergeben.
