From: T-cell activation without proliferation in juvenile idiopathic arthritis
Expression of activation and differentiation markers on T cells from peripheral blood (PB) and synovial fluid (SF) of a patient with juvenile idiopathic arthritis. (a) Expression of activation markers. (b) Expression of differentiation markers. Each histogram is a representative example of marker expression on PB or the paired SF sample. Marker expression was recorded as either percentage positive cells (CD45RO only), or as median fluorescent intensity (all other markers). The clear peak on each histogram represents the staining from an isotype-matched, negative control. FITC = fluoroscein isothiocyanate; MFI = median fluorescence intensity.
