mRNA expression levels of genes in jejunum and cecum of pigs fed experimental diets. A Genes related to inflammation cytokines (IL-8, IFN-γ, TNF-α, and IL-10); B Genes related to tight junction proteins (ZO-1, OCLD, and CLDN1); C) MUC2 expression in jejunum and cecum. ^a,b Mean values within a row have different superscript letters were significantly different (P < 0.05). Treatment groups: CON, control group fed with basal diet; SPL5, group fed with 5 mg/kg of SPL supplemented diet; SPL10, group fed with 10 mg/kg of sophorolipid-supplemented diet; SPL15, group fed with 15 mg/kg of sophorolipid-supplemented diet. Abbreviations: IL-8, interleukin-8; IFN-γ, interferon-γ; TNF- α, tumor necrosis factor- α; IL-10, interleukin-10; ZO-1, zona occludensa-1; OCLD, occludin; CLDN1, claudin-1; MUC2, mucin 2
