| Outline of Final Research Achievements |
Nakajo-Nishimura syndrome (NNS) patients derived peripheral blood monocytes produced larger amount of IP-10 than control cells after IFNγ stimulation. However, it remains unclear how proteasome disability enhances IFN signaling. By western blotting, IFNγ-induced phosphorylated JAK1 level in immortalized B cells was higher in NNS patients-derived cells than in control cells. In contrast, phosphorylated STAT1 level did not change after IFNγ stimulation in either of NNS patients-derived immortalized B cells and control cells. These results suggest that proteasome degradation of phosphorylated JAK1 is critical for IFN signaling in NNS.
