Celastrol targets LRP1 to inhibit fibroblast-macrophage crosstalk and ameliorates psoriasis progression

GSE230842 Homo sapiens Expression profiling by high throughput sequencing; Genome binding/occupancy profiling by high throughput sequencing 9 samples Submitted 2024/03/31 Platform GPL18573
Summary
In the present study, we analyzed single-cell multi-omics data from psoriasis patients and healthy individuals and found that more fibroblast-macrophage communication was present in the dermis of psoriasis lesions, exacerbating psoriasis progression. 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 cells. Moreover, conditional knockdown of LRP1 by fibroblasts significantly improved psoriasis in mice, suggesting that LRP1 may be an important target for the treatment of psoriasis.
