Outline of Final Research Achievements |
Psoriasis is a disease of Th1 and Th17 immune response. Here, we investigated the role of ganglioside of suppressing the immune response of psoriasis. IMQ applied mice was used as a psoriasis mouse model. Ganglioside GM1,GM2,GD1a,GD3,GT1b decreased the skin erythema, epidermal thickness, scale of these mice, and histopathology showed that ganglioside decreased the infiltrating T cells. Cytokine and chemokine expression of the skin , such as TNF,CXCL1/2, IL-17A, IL-22, IL-12p40, IL-23p19, CCL20 and anti microbial peptide DEFB4 expression was decreased by mRNA level. Therefore, our result suggested that IMQ suppressed and improved psoriasis like inflammation of psoriasis mice model.
