| Outline of Final Research Achievements |
We investigated the mechanisms underlying hyper-expression of Periostin in phospholipase C (PLC)-beta3 deficient fibroblasts. In addition, we examined the in vitro effects of PLC-beta3 supplement therapy. Stimulation by IL-13, which is known to activate Periostin production, induced hyper phosphorylation of both Stat5 and Stat6 in PLC-beta3 deficient fibroblasts. On the other hand, transfection of fibroblasts with fusion proteins of PLC-beta3 fragment and SHP-1 suppressed the activation of Stat5 and Stat6. These results would serve as a basis for developing new therapeutics for the atopic dermatitis targeting SHP-1-PLC-beta3-Stat5 (SPS) complex.
