| Outline of Final Research Achievements |
In GeneChip analysis, mRNAs of IL-6, IL-18, TSLP and MMP1 were highly expressed in the fibroblasts from SMG tissue of patients with IgG4-RD than in normal. The expression and secretion of IL-6 was greatly higher in IgG4-RD SMG fibroblasts than in normal. The expression and the secretion of IL-6 was upregulated by treatment with IL-1β, TNFα or TNFα/TGF-β. NF-κB inhibitor curcumin prevented the secretion and the expression of IL-6 induced by IL-1β or TNFα/TGF-β in the IgG4-RD SMG fibrobasts. Wnt1-inducible signaling protein 1 (WISP1) was also increased in the IgG4-RD SMG fibroblasts than in the normal. Curcumin also prevented WISP1 expression induced by IL-1β or TNFα/TGF-β in the normal. Treatment with IL-6 or WISP1 increased G2/M phase of the SMG fibroblasts in the normal. Expression of TSLP and IL-33 was increased in the IgG4-RD SMG fibroblasts than in the normal.
