Project description:The goal of this study was to determine whether there are any gene expression changes in pDCs from WT and Flt3 KO mice. Specifically whether developing in the absence of Flt3 signaling had any effects on the gene expression of the pDCs

Project description:Expression profiling of WT and E2A-KO LSK FLT3- and LMPP protenitor cells. Experiment Overall Design: LSK FLT3- and LMPP stem/progenitor cells from WT and E2A-KO mice were FACS sorted. Subsequently RNA was extracted, labelled and hybridized to Affymetrix microarrays. Goal of experiment was to investigate expression changes between WT and KO LMPP cells.
Project description:Type I interferons are critical anti-viral cytokines during virus infections and have also been implicated in the pathogenesis of systemic lupus erythematosus (SLE). The secretion of type I interferon of pDCs is modulated by Siglec-H, a DAP12 associated receptor on pDCs. We showed that Siglec-H deficient pDCs produce more of the type I interferon IFN-α in vitro and that Siglec-H ko mice produce more IFN-α after murine cytomegalovirus (mCMV) infection in vivo, leading to efficient clearance of the virus. Furthermore, ageing Siglec-H ko mice showed a mild form of systemic autoimmunity. In contrast, Siglec-H ko mice developed a severe form of systemic lupus-like autoimmune disease with strong kidney nephritis several weeks after a single mCMV infection. This induction of systemic autoimmune disease after virus infection in Siglec-H ko mice was accompanied by a type I interferon signature and fully dependent on type I interferon signaling. These results show that Siglec-H normally serves as modulator of type I interferon responses after infection with a persistent virus and thereby prevents induction of autoimmune disease. For microarray experiments gene expression profiles of total splenic cells from two wt and Siglec-H ko mice 26 weeks after infection with luciferase expressing murine Cytomegalovirus (5x105 pfu) or from two uninfected wt and Siglec-H ko control mice were analyzed
