Equivalent expression levels of CD1d on mDCs and lineage-positive (Lin+) cells from HDs, ACs, and HAM/TSP patients, and ATL patients. Plots of the expression level (mean fluorescence intensity [MFI]) of CD1d molecules on mDCs (A) and Lin+ cells (B) among PBMCs from HDs (n = 9), ACs (n = 7), HAM/TSP patients (n = 9), and ATL patients (n = 3). The horizontal bar represents the mean value for each group. Statistical analysis of the expression level for each study subject revealed no statistically significant differences by 1-way analysis of variance and Scheffé F test.
