We have assessed levels of surface-expressed complement regulatory proteins, decay-accelerating factor (DAF) and membrane cofactor protein (MCP) on cells from patients with hematological malignancies. Neither malignant cells nor unaffected nucleated blood cells from the patients lacked MCP. On the other hand, complete deficiency of DAF was found in 2/10 of non-Hodgkin's lymphoma (NHL), while none of the 38 patients with acute nonlymphocytic leukemia (ANLL) (14 cases), chronic myelogenous leukemia (CML) (6 cases), acute lymphocytic leukemia (ALL) (12 cases) and chronic lymphocytic leukemia (CLL) (6 cases) lacked DAF. The two patients with DAF-negative NHL had no history of paroxysmal nocturnal hemoglobinuria (PNH), and their peripheral blood cells were DAF-positive. One DAF-negative NHL exhibited T cell markers and the other those of B cell. In both cases, treatment of the DAF-negative lymphoma cells with antibody against MCP (M177) followed by Mg(2+)-EGTA-serum resulted in efficient deposition of homologous C3. These results infer that some NHL specifically lack DAF and, through treatment with M177, are targeted by homologous C3.

D008228 Lymphoma, Non-Hodgkin Any of a group of malignant tumors of lymphoid tissue that differ from HODGKIN DISEASE, being more heterogeneous with respect to malignant cell lineage, clinical course, prognosis, and therapy. The only common feature among these tumors is the absence of giant REED-STERNBERG CELLS, a characteristic of Hodgkin's disease.

D003176 Complement C3 A glycoprotein that is central in both the classical and the alternative pathway of COMPLEMENT ACTIVATION. C3 can be cleaved into COMPLEMENT C3A and COMPLEMENT C3B, spontaneously at low level or by C3 CONVERTASE at high level. The smaller fragment C3a is an ANAPHYLATOXIN and mediator of local inflammatory process. The larger fragment C3b binds with C3 convertase to form C5 convertase.

D005434 Flow Cytometry Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.
