Figure 3. NK, DN Vδ2 TCRγδ^- and DN Vδ2 TCRγδ⁺ T cells represent two-thirds of measured IFNγ-expressing cells in blood taken from infants 10 weeks after BCG immunization given at birth (n=20) or at 2 months of age (2m; n=23).

Box plots (with lower quartile, median and upper quartile, Tukey whiskers) of the proportion of DP, CD8, CD4, DN Vδ2 TCRγδ^-, DN Vδ2 TCRγδ⁺ and NK cells within the combined NK IFNγ⁺ and CD3⁺ IFNγ⁺ population. DN: CD4^-CD8^- double negative T cells. DP: CD4⁺CD8⁺ double positive T cells.
