ABSTRACT: Purpose: We aimed to find a potential for psoriasis and to explore the mechanism of SBM to relieve psoriasis-like skin inflammation in mice. Methods: Supplementation with smear administration of SBM in the imiquimod-induced murine model, record the weight change and psoriasis Area and Severity Index (PASI) score during the whole process. Using hematoxylin-eosin staining to obverse to skin structure. Performing single-cell RNA sequencing to explore the mechanism of SBM in influencing psoriasis-like phenotype. Immunofluorescence were conducted for verification. Results: SBM remarkably alleviated the psoriasis-like phenotype. Single-cell RNA sequencing analysis shown the expression of Il17 and Il23 was diminished in keratinocytes and T cells, accompanied by a reduction in the proportion of Th17 cells. Meanwhile, endothelial cell activation was inhibited along with the expression of Cxcl16. Conclusion: In this work, we found that natural product SBM inhibited the IL-23/Th17 axis and CXCL16-mediated endothelial activation and had a good therapeutic effect on psoriasis in mice model. This work suggests the potential therapeutic value of SBM in psoriatic patients.
