Dependence of γδ T-cell activity on costimulation with interleukin (IL)-2, IL-15 and IL-21. Peripheral blood mononuclear cells were incubated with medium alone (open circles), or with ΔlytB #20 at a dilution of 1 in 100 000, corresponding to a bioactivity equivalent to 25 µm isopentenyl pyrophosphate (IPP) (solid circles), in the presence of different concentrations of the recombinant cytokines. Data shown represent the mean value+SEM for expression of CD69 and CD25 on Vγ9+ CD3+ T cells, for outgrowth of Vγ9+ T cells among CD3+ T cells, and for secretion of interferon-γ (IFN-γ) and tumour necrosis factor-α (TNF-α) (all n = 6 except n = 3 for IFN-γ). *P<0·05 compared to the corresponding medium controls, using a two-tailed Student's t-test for paired data.
