a, b Expression of CD1d on monocytes and B cells, respectively. The membrane marker, CD1d, was analyzed on stored CD14+ monocytes and CD19+ lymphocytes from 10 individual healthy volunteers (HV) and 20 individual BI patients. Data are shown as the ratio of median fluorescence intensity (RFI) obtained with the specific antibodies to those obtained with their associated control isotypes. Top and bottom whiskers represent the extreme values; boxed area represents the 25th percentile, the median, and the 75th percentile (**p < 0.01, ***p < 0.001; statistical analysis, Mann-Whitney test)
