PHA-ICC, ADCC and NK in patients with ANLL in CR: human fibroblastic interferon fails to increase NK-active cell...

PHA-ICC, ADCC and NK activity of PBL were studied in ten patients with ANLL in CR and in eighteen normal controls in the presence and absence of HFIF. No statistically significant differences were recorded among the two groups with regard to basic lymphocyte functions. Although the parameters of lymphocyte function remained analogous for those tested, the analysis at the single cell level revealed that HFIF stimulation increases the number of NK active cells and target binding cells among normals, but not in leukemic patients.
