Research output: Contribution to journalComment/debatepeer-review


Skin epithelium is constituted by heterogeneous keratinocytes in different body areas. In this issue, Zhou et al. used transcriptome analysis to investigate the site-specific epidermal cell identity on volar skin. Keratin 9 is highly enriched in volar keratinocytes, and its expression is dependent on low expression of the double-stranded RNA receptor DDX58, suggesting that double-stranded RNA sensing could allow a potential approach to modulate skin thickness and durability.
