Toll-like-Rezeptor 9
Das TLR9-Gen kodiert den Toll-like-Rezeptor 9, der sich in den Endosomen von dentritischen Zellen auf die Erkennung von bakterieller DNA spezialisiert hat. Die Unterscheidung zwischen eigenem und bakteriellem Ursprung erfolgt dabei aufgrund der Fehlenden methylierung bakterieller DNA.
