| Research Abstract |
We cultured human hair follicle-derived keratinocytes (FDKs) from plucked hairs. FDKs may be an ideal cell source for personalized medicine, since they can be established without invasive biopsies. We undertook a comparative study of gene expression in FDKs from adult donors with atopic dermatitis (AD-FDKs) and non-atopic donors (Non-AD-FDKs). AD-FDKs showed higher expression of NLRP2, which encodes a component of inflammasome, and lower expression of DKK1, which encodes an inhibitor of Wnt signalling, than Non-AD-FDKs. Treatment with IFN-γ for 24 hours induced the enhanced expression of IL32, IL1B, IL8, and CXCL1 in AD-FDKs compared to Non-AD-FDKs, showing increased IFN-γ responses in AD-FDKs.
