Relative expression of cytokines. Relative expression of pro-inflammatory cytokines, a interleukin 1β, il1β, b interleukin 17a, il17a, c interleukin 8, il8 and d interferon γ, ifnγ, and anti-inflammatory cytokines, e interleukin 10, il10 and f transforming growth factor β, tgfβ. Transcripts were quantified by qPCR and normalized using the geometric average of the selected reference genes. Values are presented as means ± S.E.M. (n = 6). Different letters among values indicate statistically significant differences (p < 0.05) in each group among the sampling points. Values sharing the same letters are not statistically significant. Any significant differences between the diet groups at a sampling point are reported in the text. See Fig. 1 legend for description of the diet groups and sampling time points
