Psoriasis is a chronic, recurrent and inflammatory skin disease. Although conventional immunosuppressants can ameliorate psoriatic symptoms, it tends to relapse over time. Previous studies have shown that exosomes from both immune non-immune cells participate in immunopathology. The biologically active cargoes accelerate psoriasis progression by altering gene profiles signaling pathways of neighboring cells. On the other hand, be utilized as drug delivery platforms for treatment. Especially, engineered may serve systems effective proteins, nucleic acids or drugs due their low immunogenicity, good stability ability fuse with target Therefore, investigation into mechanisms underlying intercellular communications mediated lesions likely helps design therapy psoriasis. In this review, we summarized recent advances biogenesis potential roles pathogenesis treatment further discussed challenges future directions particular, review highlights immunoregulatory function derived exosome-based therapeutic applications psoriasis, including systems.

Psoriasis is an incurable chronic inflammatory disease that requires new interventions. Here, we found fibroblasts exacerbate psoriasis progression by promoting macrophage recruitment via CCL2 secretion single-cell multi-omics analysis. The natural small molecule celastrol was screened to interfere with the of and improve psoriasis-like symptoms in both murine cynomolgus monkey models. Mechanistically, directly bound low-density lipoprotein receptor-related protein 1 (LRP1) β-chain abolished its binding transcription factor c-Jun nucleus, which turn inhibited production skin fibroblasts, blocked fibroblast-macrophage crosstalk, ameliorated progression. Notably, fibroblast-specific LRP1 knockout mice exhibited a significant reduction like inflammation. Taken together, from clinical samples combined various mouse models, revealed pathogenesis perspective provided foundation for as novel potential target treatment.

Age-related macular degeneration (AMD) is a prevalent neuroinflammation condition and the leading cause of irreversible blindness among elderly population. Smoking significantly increases AMD risk, yet mechanisms remain unclear. Here, we investigate role Sema4D-PlexinB1 axis in progression AMD, which highly activated by smoking. Using patient-derived samples mouse models, discover that smoking presence Sema4D on surface CD8+ T cells migrate into choroidal neovascularization (CNV) lesion via CXCL12-CXCR4 interact with its receptor PlexinB1 pericytes. This leads to ROR2-mediated phosphorylation pericyte activation, thereby disrupting vascular homeostasis promoting neovascularization. Inhibition reduces CNV improves benefit anti-VEGF treatment. In conclusion, this study unveils molecular through exacerbates pathology, presents potential therapeutic strategy targeting augment current treatments. shows worsens neovascular age-related pathway. Targeting enhances therapy efficacy, offering approach.

The C-X-C chemokine receptors (CXCR) receptor family, consisting of seven primary members (CXCR1–CXCR7), is crucial in regulating immune cell recruitment, angiogenesis, cellular proliferation, and maintaining skin homeostasis functions. This review evaluates the expression roles CXCR across a range cells, including keratinocytes, fibroblasts, endothelial melanocytes, various cells such as T dendritic macrophages. Aberrations signaling have been associated with variety disorders, psoriasis, atopic dermatitis, acne, cancers. Despite significant advancements field, several critical questions persist. These include differential effects distinct pathologies intricate interactions between their ligands within diverse microenvironments. Moreover, therapeutic targeting family remains unresolved, necessitating further research into its long-term efficacy possible adverse effects. Future investigations should prioritize these issues to develop more effective strategies for managing diseases, ultimately improving patient outcomes.
