银屑病神经免疫和表观遗传微环境的空间图谱
A spatial atlas of neuroimmune and epigenetic microenvironment in psoriasis
摘要
Abstract
AIM:Psoriasis is a chronic inflammatory skin disease with keratinocyte hyperproliferation and im-mune dysregulation,yet the spatial epigenetic and neuroimmune features within the skin remain poorly understood.This study aims to construct a spatial atlas of the neuroimmune and epigenetic microenvironment in psoriasis.METHODS:Formalin-fixed,paraffin-embedded skin tissue samples from five psoriasis patients and four healthy controls were stained with a 33-metal antibody panel targeting immune and epigenetic markers.Imaging data were processed to analyze immune cell composition,spatial relationships,and epigenetic marker distribution in psoriatic lesions.RESULTS:Analysis of over 163 000 cells from five psoriasis patients and four healthy controls revealed that psoriatic lesions have a more complex cellular composition than normal skin,including diverse immune subsets,endothelial cells,keratinocytes,and nerve fi-bers.Neighborhood analysis showed enrichment of multiple immune cells,such as CD14+monocytes,CD4+/CD8+T-lym-phocytes(T cells),CD68+macrophages,CD69+tissue-resident memory T cells and CD20+B-lymphocytes(B cells),and nerve fibers around keratinocytes.Notably,positive interactions were observed between cutaneous nerve fibers and specif-ic immune cells(CD8+T cells and CD68+macrophages)as well as blood vessels.Additionally,histone H3 lysine 27 tri-methylation(H3K27me3)modification was mapped across cell types and found in immune cells adjacent to keratinocytes.CONCLUSION:Imaging mass cytometry delineated the psoriatic microenvironment's multicellular structure integrating epigenetic and neuroimmune components,offering new insights into psoriasis pathogenesis.关键词
