Immunologic and ultrastructural heterogeneity of acute lymphoblastic leukemia-associated antigen-positive human leukemias. 1980

T W LeBien, and J L Parkin, and R D Brunning, and J H Kersey

To further examine the heterogeneity of human acute lymphoblastic leukemia, an immunologic and ultrastructural study was undertaken on 14 patients positive for the acute lymphoblastic leukemia-associated antigen (ALLA). In malignant cells from 7 of the patients studied, cytoplasmic granular inclusions that resembled those seen in leukemia mast cells and basophils (M-B granules) were evident. Four patients had malignant cells expressing the pre-B-cell phenotype (i.e., cytoplasmic IgM-positive and surface immunoglobulin-negative), and 3 patients had malignant cells that lacked both M-B granules and cytoplasmic IgM. These results support the existence of distinct phenotypic subgroups within the ALLA+ leukemias.

UI	MeSH Term	Description	Entries
D007075	Immunoglobulin M	A class of immunoglobulin bearing mu chains (IMMUNOGLOBULIN MU-CHAINS). IgM can fix COMPLEMENT. The name comes from its high molecular weight and originally was called a macroglobulin.	Gamma Globulin, 19S,IgM,IgM Antibody,IgM1,IgM2,19S Gamma Globulin,Antibody, IgM
D007223	Infant	A child between 1 and 23 months of age.	Infants
D007945	Leukemia, Lymphoid	Leukemia associated with HYPERPLASIA of the lymphoid tissues and increased numbers of circulating malignant LYMPHOCYTES and lymphoblasts.

D008214	Lymphocytes	White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS.	Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
D008297	Male		Males
D008407	Mast Cells	Granulated cells that are found in almost all tissues, most abundantly in the skin and the gastrointestinal tract. Like the BASOPHILS, mast cells contain large amounts of HISTAMINE and HEPARIN. Unlike basophils, mast cells normally remain in the tissues and do not circulate in the blood. Mast cells, derived from the bone marrow stem cells, are regulated by the STEM CELL FACTOR.	Basophils, Tissue,Basophil, Tissue,Cell, Mast,Cells, Mast,Mast Cell,Tissue Basophil,Tissue Basophils
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D001853	Bone Marrow	The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.
