MALT1 and diffuse large B-cell lymphoma: To determine the extent to which the anti-cytotoxicity effects of MALT1 protease activity in ABC-DLBCL cells are glutaminolysis-dependent, we pretreated ABC-DLBCL cells with z-VRPR-fmk and BPTES separately or in combination followed by co-culture with Vγ9Vδ2 T lymphocytes.
