The detection of Fc-IgA receptors on T and non-T, non-B acute leukemic lymphoblasts
1980
Abstract Fc-IgA receptors have been described on purified human T-lymphocyte populations from normal individuals. More recently, non-T-cell subpopulations bearing Fc-IgA receptors have also been described. In this study, receptors for the Fc portion of IgA were detected on both T and non-T, non-B leukemic lymphoblasts from 15 patients with acute lymphoblastic leukemia (ALL). From 1.6 to 6.8% of the T lymphoblasts of 7 patients expressed Fc-IgA receptors and 0.5 to 3.9% of the non-T, non-B lymphoblasts of the remaining 8 patients expressed Fc-IgA receptors. The expression of IgA receptors on these cells may reflect the maturational state of these leukemic lymphoblasts. The detection of Fc-IgA receptors on leukemic lymphoblasts suggests that expression of these receptors on lymphoid cells represents an early maturational event.
