IFN-γ response by Vδ2 T subsets to Isopentenyl Pyrophosphate stimulation. Comparison of median IFN-γ responses by Vδ2 T cells after stimulating with 50 μM IPP for 24 h in 22 HIV + TB-, 10 HIV-TB+ patients and 20 healthy controls. IFN-γ response is depicted as optical density (OD) of the supernatant, as described in materials and methods. p-value is from the Mann-Whitney U test
