Compared to healthy control skin, nonlesional MF still harbored increased levels of type-2 associated chemokines such as CCL13 and CCL18 in macrophages, type-1 associated chemokines CXCL9 and CXCL10 in dendritic cells, as well as activation markers such as MX1 and S100A8 in keratinocytes (Fig. S8E-F, Table S23), suggesting some retained inflammatory environment, despite the absence of clinically visible MF involvement. This evidence concerns the gene CXCL9 and mycosis fungoides.
