Plasmablastic lymphoma
(PBL) is a rare, highly aggressive subtype of non-Hodgkin lymphoma with plasma-cell differentiation occurring typically in immune-suppressed patients such as those with AIDS. This study reports the establishment and characterization of a new cell line, PBL-1, derived from a patient with AIDS-associated PBL. Morphological assessment of PBL-1 indicated plasma-cell differentiation with a CD20(-) CD38(+) CD138(+) immunophenotype and IgH/c-myc translocation. The cell line harbours Epstein-Barr virus, but a 52.7-kbp length defect was identified in its genome, resulting in no expression of viral microRNAs encoded in the BamHI-A Rightward Transcript region. Importantly, supplementation of culture medium with >5 ng/mL of
interleukin-6
(
IL-6
) was required for PBL-1 growth. Starvation of
IL-6
or addition of tocilizumab, an inhibitory antibody for the
IL-6
receptor, induced apoptosis of PBL-1. Transduction of
IL-6
into PBL-1 by lentivirus vector induced autologous growth without
IL-6
supplementation of culture medium. These data indicate the
IL-6
dependency of PBL-1 for proliferation and survival. mTOR inhibitors induced cell death effectively, suggesting mTOR in the
IL-6
signalling pathway is a potential therapeutic target for PBL. This established PBL cell line will be a useful tool to further understand the pathophysiology of PBL and aid the future development of PBL treatment.
