iNKT and type II NKT cells produce IFN-γ after SA infection. (A, B) Representative FACS plots of IFN-γ production of iNKT (A) and type II NKT (B) cells at 1 dpi from B6 liver, cultured directly ex vivo. (C, D) Quantified % cytokine production, gated on iNKT cells (C) and type II NKT cells (D). (N=3–6 naïve, N=5–12 infected mice). (E) rtPCR of cytokine mRNA of type II NKT cells sorted from 4 dpi Jα18-/- mouse pooled liver lymphocytes (N=10 mice) compared to sorted conventional CD4+NK1.1- T cells from Jα18-/- splenocytes (N=2 mice), data represented as cytokine mRNA levels relative to β-actin. Statistical analysis: (C–E) 2-way ANOVA. *p < 0.05; ***p < 0.001; ****p < 0.0001.
