Fig 1: CD155 surface expression by APCs. Pooled flow cytometry analysis of PBMCs ex vivo, of healthy controls (n = 7, symbol with cross), psoriasis (n = 7, open symbol), and psoriatic arthritis (n = 7, filled symbol) patients. Shown data are from six APC subsets: CD14+CD16- classical monocyte (cM), CD14+CD16+ intermediate monocyte (iM), CD14-CD16+ non-classical monocyte (ncM), CD141+ myeloid DC (mDC), CD1c+ mDC, and CD303+ plasmacytoid DC (pDC). (A) Proportion of APC subset in PBMCs (gate ‘Single Cells’ Supplementary Fig. S1A). (B) Proportion of CD155-positive cells in APC subset. (C–H) Gating strategy of the selection of CD155-positive cells in cM (C), iM (D), ncM (E), CD141+ mDC (F), CD1c+ mDC (G), and pDC (H).
