HLA class I allelic expression levels were determined by flow cytometry on leukemic cells and on autologous normal T cells. All cells tested were untouched cell fractions obtained by immunomagnetic procedures. The results are expressed as MFI after background correction. The ratio R was derived from MFI malignant cells/MFI normal cells. An R value lower than 1 was considered as down-regulation of that particular allele.
H indicates homozygous; ND, not done or no specific antibody available; and —, not available or not appropriate.
An R value less than 1 was considered a down-regulation of that particular allele.
