Cytokine production by NKT cells after FV infection. Bone marrow cells (white bars) and splenocytes (grey bars) were isolated from naïve or FV-infected mice (3 dpi). Cells were stimulated and stained for the pro-inflammatory cytokines IFNγ (a) and TNFα (b) and the anti-inflammatory cytokines IL-10 (c) and IL-13 (d). Mean (±SEM) values are indicated by bars. At least nine animals per group out of at least six experiments were used for analysis. Differences between naïve and FV-infected mice were analyzed using the Mann–Whitney test and are indicated by single asterisk for p < 0.05 and double asterisk for p < 0.01
