Abstract :
Primary effusion lymphoma (PEL) is a subtype of aggressive and resistant non-Hodgkin lymphoma that occurs predominantly in patients with advanced AIDS. In this study, we examined the antitumor activity of zoledronic acid (Zol)-induced Vγ9Vδ2 T cells against PEL cells in vitro and in vivo. Vγ9Vδ2 T cells recognized endogenous mevalonate metabolites and MICA/B of PEL cell lines, inducing cytotoxicity via granule exocytosis and TRAIL-mediated pathway. Vγ9Vδ2 T cells suppressed the development of PEL cells and existed in a PEL xenograft mouse model. These results show that immunotherapy with Zol-induced Vγ9Vδ2 T cells could demonstrate an efficient strategy for PEL.
