Expression of activation markers and co-stimulatory molecules in immature and mature monocyte-derived dendritic cells from primary Sjögren’s syndrome patients and controls. For all samples, the percentage of positive cells or the median fluorescence intensity (MFI) of the negative control was subtracted. Percentages of monocyte-derived dendritic cells (moDC) being positive for (A) HLA-DR, (C) CD86, (E) CD83, (G) CD80 and (I) CCR7. MFI of the corresponding moDC for (B) HLA-DR, (D) CD86, (F) CD83, (H) CD80 and (J) CCR7. Primary Sjögren’s syndrome patients, P immature n = 12 and P mature n = 10; controls, C immature n = 15 and C mature n = 11.
