Establishment of a new Epstein-Barr virus-immortalized cell line from chronic lymphocytic leukemia with trisomy of chromosome 12 that produces monoclonal IgM against a sheep RBC antigen.

چکیده
Leukemia cells from a patient with chronic lymphocytic leukemia (CLL) were found to bind sheep RBC (SRBC) through their monoclonal surface IgM. A lymphoblastoid cell line was obtained by immortalization of leukemic cells with Epstein-Barr virus (EBV). Cultured leukemic cells were found to have a supernumerary chromosome 12, an abnormality typical of CLL of the B cell type. To our knowledge, this is the first EBV-immortalized cell line from B-CLL cells of known SRBC specificity and the third reported CLL cell line carrying trisomy of chromosome 12.

BACKGROUND small B-cell neoplasms can show plasmacytic differentiation and may potentially progress to aggressive lymphoma (DLBCL). Epstein-Barr virus (EBV) infection may cause the transformation of malignant cells in vitro. DESIGN AND METHOD we established VR09 cell line with plasmacytic differentiation, obtained from a case of atypical, non-CLL B-cell chronic lymphoproliferative disease wit...
متن کاملSpontaneous Epstein-Barr virus transformed B-cell line sharing the identical immunoglobulin gene rearrangement with acute myeloid leukemia.
Mononuclear cells from a 44-year-old patient with acute myeloid leukemia (AML) gave rise to a spontaneous permanent cell line cultured in suspension. The cell line was shown to be positive for Epstein-Barr virus nuclear antigen (EBNA). As expected, its composite phenotype was of B-cell type with B-cell antigens (CD 20, CD 21) and with monoclonal surface IgM of kappa type, but without detectable...

Immortalized cell lines representative of chronic lymphocytic leukemia (CLL) can assist in understanding disease pathogenesis and testing new therapeutic agents. At present, very few representative cell lines are available. We here describe the characterization of a new cell line (PCL12) that grew spontaneously from the peripheral blood (PB) of a CLL patient with progressive disease and EBV inf...
