BALB/c female mice (5–6 weeks of age) were fed chewy granola bars supplemented with (Test) or without (Control) Ai/E10 for 10 days. After the feeding period, the animals were sacrificed and spleen cells were isolated and incubated with lipopolysaccharide and phorbol myristate acetate-ionomycin. RNA was extracted and mRNA expression of 84 genes involved in innate and acquired immunity was determined with real-time PCR arrays. Numerous genes associated with innate and adaptive immunity were upregulated in the Test group when stimulated with mitogens. Significant upregulation was observed in 30% (25 of 84) of genes upon lipopolysaccharide stimulation and in 14% (12 of 84) of genes upon phorbol myristate acetate + ionomycin stimulation in the Test group relative to Controls. This study illustrates that Ai/E10 supplementation results in significant and specific upregulation of genes associated with innate and adaptive immunity in mice. Notably, this effect was observed only in stimulated cultures.
