Open Access Abstract Dendritic cells DCs comprise heterogeneous subsets of professional antigen-presenting cells linking innate and adaptive immunity. Analysis of DC subsets has been hampered by a lack of specific DC markers and reliable quantitation assays. We characterised the immunophenotype and functional characteristics of psoriatic arthritis PsA -derived and rheumatoid arthritis RA -derived myeloid DCs mDCs and plasmacytoid DCs pDCs to evaluate their potential role in arthritis. Circulating peripheral blood PB pDC numbers were significantly reduced in PsA patients P and RA patients P and mDCs were significantly reduced in RA patients P compared with healthy controls. The number of circulating mDCs in RA PB was .
