Final Report Abstract
Uns gelang es, die Rolle von Langerhanszellen im experimentellen Modell der Leishmaniose neu zu definieren. Wir konnten zeigen, dass Langerin+ dendritische Zellen und Langerhanszellen wichtig dafür sind, T-Zellen (TFH Zellen, regulatorische T-Zellen und CD8+ T-Zellen) zu konditionieren. Für eine Ausbildung einer protektiven TH1-Antwort gegen L. major sind sie jedoch nicht notwendig. Somit kann Langerhanszellen zweifelsohne eine immunmodulatorische Eigenschaft zugesprochen werden. Andere Arbeitsgruppen können unsere Arbeiten reproduzieren.
