Purified human thymus-derived (T) lymphocytes were analyzed by detection of Fc receptors for either IgG or IgM in healthy controls and in patients with chronic lymphocytic leukemia (CLL). There was a significant and persistent increase in the numbers of T cells bearing receptors for IgG (Fcγ) in CLL patients in comparison to the controls. After an in vitro culture period, there was a significantly decreased appearance of cells with IgM receptors (Fcμ) in CLL patients in comparison to the control group. These results indicate an imbalance in circulating T-cell subpopulations for CLL patients. In addition, an in vitro defect in CLL T-cell membrane receptor appearance is present.
