| Outline of Final Research Achievements |
Recently, a lot of study have been reported about the pathology of psoriasis. It remains unclear that the localization of Treg and Th17 cell in the local skin and the mechanism of action among these cells. Therefore, in this study, we examined how the localization of regulatory T cells and Th17 cells in the lesional skin of psoriasis patients and the proportion of IL-17 in the peripheral blood are related to psoriasis severity. Regarding local skin, skin biopsy was performed to prepare a frozen specimen, which was then stained with CD4, Foxp3, IL-17 and its localization and number were examined with a fluorescence microscope.The serum cytekine were determined by Cytometric Bead Array system. We analysed these factors using multiple regression analysis and finally obtained the formula: PASI score=0.31×IL-17+1.62×TNF-α＋11.4 (p=0.028).
