Transcriptome of inflammatory myeloid DCs in psoriasis

ABSTRACT: Background: Previous work has identified CD11c+CD1c- dendritic cells (DCs) as the major 'inflammatory' dermal DC population in psoriasis vulgaris and CD1c+ DCs as the 'resident' cutaneous DC population. Objective: To further define molecular differences between these two myeloid dermal DC populations. Methods: Inflammatory and resident DCs were single-cell sorted from psoriasis lesional skin biopsies, and gene array expression profiling was performed. Results were confirmed with RT-PCR, flow cytometry, immunohistochemistry, and double label immunofluorescence. Pooled human keratinocytes were cultured for functional studies. Results: TNF-related apoptosis-inducing ligand (TRAIL), Toll-like receptors (TLRs) 1 and 2, S100A12/EN-RAGE, CD32, and many other inflammatory products were selec
