| Outline of Final Research Achievements |
Nakajo-Nishimura syndrome (NNS) is a proteasome-associated autoinflammatory syndrome caused by PSMB8 gene mutation. The pathogenesis of and treatment for NNS remain to be established. We have studied these by using NNS-specific iPS cell.
Chymotrypsin-like proteasome activity decreased in monocyte-like cells derived from NNS-specific iPS cells compared to that from control iPS cells. Inflammatory cytokines such as IL-6 were higher in culture supernatant of monocyte-like cells derived from NNS-specific iPS cells than that from control iPS cells. These results were consistent with those of primary monocyte of NNS patients. We are going to continue the study for pathogenesis of and drug discovery for NNS with this technique.
