Chronic myelocytic leukemia: eosinophils involved in the malignant clone
HP Koeffler, AM Levine, M Sparkes and RS Sparkes
Chronic myelocytic leukemia (CML) is a clonal disorder involving
neutrophil, monocyte, erythrocyte, and platelet precursors. In order to
determine if the eosinophils are also involved in the leukemic clone, we
purified the eosinophils from a woman heterozygous for the common
electrophoretic variants of the G6PD gene. Only type B enzyme was
demonstrable in the eosinophils, neutrophils, and red cells, but both A and
B enzymes were found in the fibroblasts. The data provide evidence that the
eosinophil is involved in the malignant clone.
