Figure 6: FACS analysis of IFN-γ+ splenocytes with and without P. pneumotropica infection in WT mice depleted of NK1.1+ cells. (A–F) Total percentage of IFN-γ+ cells and in different subsets – CD4+ T cells, CD8+ T cells, NK cells (CD3-NK1.1+), CD4+ NKT cells, and CD8+ NKT cells – for WT mice treated with the NK1.1-depleting antibody PK136. Data show mean ± SD. Student’s t-test was used to evaluate significant differences between the groups; n = 3–6 mice/group, **P ≤0.01, ***P ≤0.001.
