Summary:
Purpose: This study aimed to explore the mechanism of Celastrol in improving psoriasis through single-cell transcriptomicsMethods: Supplementation with intragastric administration of celastrol in C57BL/6 mice to observe its effect on IMQ-induced psoriasis. Single-cell RNA sequencing were performed to explore the role of celastrol for IMQ-induced psoriasis.Results: A natural product library was used to screen for a small molecule compound, celastrol, that could interfere with fibroblast-macrophage communication. It was demonstrated that celastrol targeted low-denisity lipoprotein receptor-related protein 1 (LRP1) to inhibit fibroblast secretion of CCL2 and inhibited psoriasis progression by reducing its recruitment to macrophages, thereby blocking communication between the two cellsConclusion: We report that celastrol targeted low-denisity lipoprotein receptor-related protein 1 (LRP1) to inhibit fibroblast secretion of CCL2 and inhibited psoriasis progression by reducing its recruitment to macrophages. The use of celastrol maybe a noveltherapeuticoption for psoriasis.
