Figure Lengend Snippet: (A–C) C57BL/6 (WT) and IFN-γ −/− mice ( n = 5 mice/group) received daily i.p. injections of IL-12 Fc, IL-12 3x Ala Fc, or an IgG2a Fc as a control and mice were euthanized on day 4 and lungs harvested for analysis of myeloid cells (CD3 − , Ly6G − , B220 − , Sirtpa + , CD11c − ) by flow cytometry. (A) Quantification of total monocyte and macrophage cells in the lung for 1 representative experiment of 3 performed. Data are presented as x ‾ ± S E M with statistical significance determined by two-way ANOVA and Tukey’s multiple correction (* p < 0.05 and ** p < 0.005).

(D) Representative histograms of PD-L1, CD80, and CD86 on inflammatory monocytes (Ly6C + MHCII + ) with quantification of the geometric mean fluorescence intensity. Data are presented as x ‾ ± S E M from a single experiment with n = 5 per group, and similar results were seen in a repeat experiment.

Figure Lengend Snippet: IFN-γ Thy1.1 reporter mice received daily i.p. injections of IL-12 Fc, IL-12 3x Ala Fc, or an IgG2a Fc fragment as a control and were euthanized after 7 days, and the spleen and liver were analyzed to characterize the natural killer (NK) and innate-like cell 1 (ILC1) response. (A) Quantification of the total splenic NK and ILC1 cell populations ( n = 5 per group, x ‾ ± S E M ). NK cells are defined as live, singlets, CD3 − , NK1.1 + Tbet + Eomes + and ILC1s are defined as live, singlets, CD3 − , NK1.1 + Tbet + Eomes − . Data shown are representative of 3 experiments performed. Statistical significance was determined by one-way ANOVA and Tukey’s multiple correction; (*** p < 0.001 and **** p < 0.0001). (B and E) Representative flow plots depicting splenic and lung NK cells (defined as Eomes high and Eomes low populations) and splenic ILC1 cells after gating down to live, singlets, CD3 − , NK1.1 + . (C and F) Representative flow plot depicting bound IL-12 agonist x Thy1.1 expression for each subset of splenic NK cells (defined as Eomes high and Eomes low populations) and ILC1 cells. (D) Quantification of the number of NK and ILC1 cells in the lung ( n = 3–4 per group, x ‾ ± S E M ), representative of 3 experiments performed. Statistical significance was determined by one-way ANOVA and Tukey’s multiple correction (* p < 0.05). (G) Frequency of total NK1.1 + IL-12Fc + and Thy1.1 + cells at the indicated time points in the spleen and lung of IFN-γ reporter mice ( n = 3–4 per group, x ‾ ± S E M ). Statistical significance was determined by one-way ANOVA and Tukey’s multiple correction (** p < 0.005, *** p < 0.001, and **** p < 0.0001).

Figure Lengend Snippet: IFN-γ Thy1.1 reporter mice received daily i.p. injections of IL-12 Fc, IL-12 3x Ala Fc, or an IgG2a Fc fragment, and spleen and lung were harvested on day 7 for analysis. (A) Quantification of the total number of CD3 + (CD4 − CD8 − ) DN NKT cells in the spleen ( n = 6 group, pooled data from 2 independent experiments, x ‾ ± S E M ). Statistical significance was determined by one-way ANOVA and Tukey’s multiple correction (* p < 0.05). (B) Frequency of splenic Thy1.1 + CD3 + (CD4 − CD8 − ) DN NKT cells ( n = 6 group, pooled data from 2 independent experiments, x ‾ ± S E M ).
