Kontrolle von HSV-1 spezifischen Replikations- und Transmissions-Mechanismen in humanen Dendritischen Zellen
Zusammenfassung der Projektergebnisse
In summary, in our view project was a very successful leading to new and unexpected data, including the fact that autophagic degradation of lamins is essential for the nuclear egress of HSV-1 and that mDC hamper this process, by upregulating KIF1B and KIF2A molecules, and thereby inhibiting the generation of mature infectious viral particles. In addition, we found that HSV-1 derived L-particles modulate the phenotype and stimulatory function of mDCS. Furthermore, targeting IL-6 R expression by HSV-1 on mDCs has been identified as a new viral immune escape mechanism. Finally, we provide data showing that HSV-2 interferes with DC migration and therefore the induction of potent antiviral immune responses. Work regarding mechanisms related to CD83 degradation and the functional ligand studies are still ongoing.
