RT-qPCR analysis of the expression of immune-related genes in intestinal tissues of the mice, along with ELISA detection of antibody levels in the intestine. (a) TLR2, (b) MyD88, (c) TRAF6, (d) p65, (e) IRF7, and (f) IL-1β. The mRNA levels of each gene were standardized relative to the expression of the GAPDH gene. Detection of (g) IgG and (h) IgA antibodies in the intestine. *, p < 0.05;**, p < 0.01; ***, p < 0.001
