Epigenetic reprogramming in human skin inflammatory disorder HS. Compared to healthy skin, HS lesional epidermis is surrounded by heterogenous basal stem/progenitor cells with a significantly increased number of PTTG1+, HELLS+, and COL17A1+ cells favoring the recruitment of HS-associated immune cells. Stem cells lose their identity and differentiate to favor the formation of an epidermal cyst. HS-specific S100A+ keratinocyte cells amplify immune responses. After early inflammatory signals, substantial chromatin remodeling occurs in the genomic landscape of basal keratinocytes causing transcriptional activation of HS-associated genes to further drive recurrent inflammatory insults. The figure was created using Biorender.
