FIG 5.

HLA and KIR3DL1 allotypes are expressed at distinct intensities on CD4 T cells and NK cells, respectively. (A) The y axis shows the mean fluorescence intensity (MFI) of expression of HLA-Bw4 antigens from individuals carrying distinct HLA genotypes by use of a MAb specific for HLA-Bw4. (B) The y axis shows the MFI generated by staining CD4 T cells from Bw6 hmzs, Bw4/Bw6 heterozygotes, and Bw4 hmzs with the HLA-Bw4-specific MAb. (C) The y axis shows the MFI of expression of KIR3DL1-high allotypes versus KIR3DL1-low allotypes on spKIR3DL1⁺ NK cells. Each point indicates results for a single individual. For each data set, the bar height and error bars show the median and interquartile range, respectively.
