Figure 5. PD-L1 and PD-L2 affect the cytokines produced by lung iNKT cells after IAV infection.

iNKT cells were positively selected from influenza A infected lungs on day 5 from PD-L1^−/−, PD-L2^−/− and wild type BALB/c mice and different cytokines were analysed by quantitative RT-PCR normalized to β-actin levels. Data presented as mean ± SEM. * P>0.05, ** P>0.01 and *** P>0.001 as calculated by a one-way ANOVA with Tukey post hoc test and is representative of five independent experiments with n of 5 per group.
