Expression of NK-lineage markers on peripheral blood lymphocytes with T-helper (Leu3+/T4+) phenotype in B cell chronic lymphocytic leukemia.

Abstract

Heterogeneity within lymphocyte subsets expressing T-helper (T4+/Leu3+) or T-suppressor (T8+/Leu2+) markers was analyzed in 38 patients with B cell chronic lymphocytic leukemia (B-CLL) and in 11 age-matched controls. Co-expression of NK-lineage markers (M1, Leu7) on Leu2+ or Leu3+ cells was investigated by two-color immunofluorescence, and the proportion of… (More)
