S1P1-Signalweg beeinflusst Th17-Differenzierung
Der Austritt von Lymphozyten aus peripheren lymphatischen Geweben ins Blut wird durch den S1P1-Signalweg vermittelt. Fingolimod (FTY720, Gilenya®) ist ein zur Behandlung von Multipler Sklerose (MS) zugelassener funktioneller S1P1-Antagonist, da nach Bindung von Fingolimod an den S1P1-Rezeptor dieser internalisiert und abgebaut wird. Hierdurch fehlt den Lymphozyten – insbesondere naiven und central memory T-Zellen – das für das Verlassen des lymphatischen Gewebes notwendige Signal, und die Zellen verbleiben in den lymphatischen Organen.
