Abstract

We investigated the role of the epithelium of nodules in Hurley stage I hidradenitis suppurativa (HS) by using spatial transcriptomics to analyse the profiles of epithelial cells and dermal-infiltrating immune cells. Compared with epidermal cysts, genes related to bacterial response, inflammatory mediators and neutrophil degranulation pathways were upregulated in the epithelial cells of early-stage HS nodules. Our analysis of dermal-infiltrating immune cells surrounding the epithelium of nodules revealed significantly elevated levels of B-cell-related genes. Similarly to the sinus tract formation observed in moderate-to-severe HS, we propose that the production of inflammatory mediators in early-stage HS may involve the activation of keratinocytes and their interaction with dermal-infiltrating immune cells.
