Mitogenic stimulation of malignant B cells. Chronic lymphocytic leukaemia: relationship between stimulation and surface phenotype. 1982

A C Bloem, and E J Bast, and F H Gmelig Meyling, and G C DeGast, and R E Ballieux

Peripheral blood lymphocytes (PBL) from 14 patients with chronic lymphocytic leukaemia (CLL) were stimulated with pokeweed mitogen (PWM), formalinized Staphylococcus aureus (Sta) and a combination of both mitogens. The leukaemic B cells were characterized by rosetting techniques (using mouse erythrocytes and complement coated erythrocytes) and immunofluorescence for membrane bound immunoglobulin (mIg). No clear correlation between phenotype and the reactivity with PWM could be found. Results of stimulation with Sta however, indicate that lymphocytes carrying membrane bound IgM (mIgM) and IgD (mIgD) and the receptor of the third complement component (C3R) can be induced to differentiate into immunoglobulin (Ig) containing cells. Addition of PWM to these cultures often enhanced this response. Some leukaemic B cells are able to differentiate after challenge with the appropriate stimulus.

UI MeSH Term Description Entries
D007072 Immunoglobulin D An immunoglobulin which accounts for less than 1% of plasma immunoglobulin. It is found on the membrane of many circulating B LYMPHOCYTES. IgD,IgD1,IgD2
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
D007945 Leukemia, Lymphoid Leukemia associated with HYPERPLASIA of the lymphoid tissues and increased numbers of circulating malignant LYMPHOCYTES and lymphoblasts. Leukemia, Lymphocytic,Lymphocytic Leukemia,Lymphoid Leukemia,Leukemias, Lymphocytic,Leukemias, Lymphoid,Lymphocytic Leukemias,Lymphoid Leukemias
D007958 Leukocyte Count The number of WHITE BLOOD CELLS per unit volume in venous BLOOD. A differential leukocyte count measures the relative numbers of the different types of white cells. Blood Cell Count, White,Differential Leukocyte Count,Leukocyte Count, Differential,Leukocyte Number,White Blood Cell Count,Count, Differential Leukocyte,Count, Leukocyte,Counts, Differential Leukocyte,Counts, Leukocyte,Differential Leukocyte Counts,Leukocyte Counts,Leukocyte Counts, Differential,Leukocyte Numbers,Number, Leukocyte,Numbers, Leukocyte
D008213 Lymphocyte Activation Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION. Blast Transformation,Blastogenesis,Lymphoblast Transformation,Lymphocyte Stimulation,Lymphocyte Transformation,Transformation, Blast,Transformation, Lymphoblast,Transformation, Lymphocyte,Activation, Lymphocyte,Stimulation, Lymphocyte
D008934 Mitogens Substances that stimulate mitosis and lymphocyte transformation. They include not only substances associated with LECTINS, but also substances from streptococci (associated with streptolysin S) and from strains of alpha-toxin-producing staphylococci. (Stedman, 25th ed) Mitogen,Phytomitogen,Phytomitogens
D010641 Phenotype The outward appearance of the individual. It is the product of interactions between genes, and between the GENOTYPE and the environment. Phenotypes
D011043 Pokeweed Mitogens Proteins isolated from the roots of the pokeweed, Phytolacca americana, that agglutinate some erythrocytes, stimulate mitosis and antibody synthesis in lymphocytes, and induce activation of plasma cells.

D011947 Receptors, Antigen, B-Cell IMMUNOGLOBULINS on the surface of B-LYMPHOCYTES. Their MESSENGER RNA contains an EXON with a membrane spanning sequence, producing immunoglobulins in the form of type I transmembrane proteins as opposed to secreted immunoglobulins (ANTIBODIES) which do not contain the membrane spanning segment.
