We will focus our research on two tasks:
For this purpose, our collection of human CD34+ hematopoietic progenitor cells have been typed for MS associated SNPs and spontaneous immune system activation after reconstitution of human immune system components will be monitored in NOD-scid gc-/- (huNSG mice). In addition to this steady-state activation the degree of CD8+ T cell expansion after EBV infection was monitored in correlation with the genotype of the reconstituted immune system components. These experiments identified SNPs, which correlated with higher immune activation and a symptomatic course of EBV infection that is reminiscent of infectious mononucleosis. The respective SNPs will be further characterized in order to determine if MS associated SNPs predict an increased basal immune activation of human immune system components and increased infectious mononucleosis symptoms after EBV infection of the respective huNSG mice.
