Fig 1: LMP2A does not affect the level of BAFF-R or TACI. LMP2A-negative (BJAB Vector.1, BJAB Vector.2, BJAB BCM1, RAMOS-PBAM) and LMP2A-positive (BJAB LMP2A1.1, BJAB LMP2A1.2, BJAB B2CL2, RAMOS-PMP2) B cell lines were analyzed for flow cytometry for BAFF-receptor (A, B) or TACI (C, D) the data in (A, C) are representative flow cytometry plots with the shaded histograms representative of LMP2A-positive cells and nonshaded histograms representative of LMP2A-negative cells. The histogram representative with the dotted line represents the staining pattern of the isotype control for those cell lines. (B, D) represent combinations of the mean fluorescence intensity (MFI) from three experiments analyzing BAFF-R or TACI, respectively with a p =.05. BCMA was not detected on any of the cell lines analyzed (data not shown). BAFF, B cell Activating Factor of the tumor necrosis factor family; BCMA, B cell maturation antigen; LMP2A, Latent Membrane Protein 2A; TACI, transmembrane activator and calcium-modulator and cyclophilin ligand interactor.
