(G) Comparison of compound 7 (left panel) with zoledronic acid (right panel) concentrations used to pretreat tumor cells for half-maximal stimulation of TNF-α production by Vγ2Vδ2 T cells. Ly = lymphomas, My = myeloid leukemia, Ma = mammary carcinomas, and Others = other tumor cell lines. Details of zoledronic acid stimulation of Vγ2Vδ2 T cells are from Idrees et al.46 and are included for comparison.
