In this study, we demonstrate that IL-4 and IL-13 exhibited differential effects on CD23 and CD44 expression and binding to hyaluronan in BL30/B95-8, a Burkitt's lymphoma (BL), and MK3.31, an Epstein-Barr virus transformed normal human B cell line (B-LCL).
BALM-13 was characterized as belonging to the Burkitt lymphoma group III cell type (CD10-, CD20+, CD23+, D39+, CD77-), and BALM-14 to the Burkitt lymphoma group I cell type (CD10+, CD20+, CD23-, CD39-, CD77+).
Unlike that observed in certain Burkitt lymphoma (BL) cell lines that share the same surface phenotype (CD10+CD38+CD23-CD39-), the c-myc-transfected cells expressed lymphocyte function-associated (LFA) 1, LFA-3, and intercellular adhesion molecule 1 and grew in large clumps rather than single-cell layers.
Hybridization in situ demonstrated expression of EBV-encoded RNA (EBER), the cellular c-fgr protooncogene, and CD23 B-cell activation transcripts in the Wiskott-Aldrich lymphoma whereas EBER and c-fgr but not CD23 were expressed in the Burkitt's lymphoma.
TP expression was high in Burkitt's lymphoma lines with the group II and group III phenotypes (CD21+ CD23+ CD30+ CDw70+), in B95-8 and AG876 virus-converted lines, and in EBV-immortalized cells.
