In the original Article, Figure 7 was inadvertently published twice, appearing also as Figure 8. The correct Figure 8 and its corresponding figure legend is provided below. The original Article has been corrected.

Incorrect Figure 8

Incorrect Figure 8 legend:

Cytokine relative quantification by RT-qPCR in GALT at the end point of the experiment of all challenged groups relative to the NC. a Schematic representation of sample origin. b Heatmap representation of the average expression of cytokines; in red upregulated and in green downregulated gene expression. Bar charts showing log2 fold change between groups. c IL-12B, d IL-1β, e TNF, f IL-2, g IL-23A, h IL-10, i Table summarizing significant differences between groups in cytokine expression and the Absolute Fold Change Factor. All values were means with error bars representing standard deviation from groups of n = 5, except for NC which was n = 4. ANOVA with Tukey’s post-host test was applied and signification levels are *p < 0.05, **p < 0.01, ***<0.001.
