Fig. 8From: Oral recombinant Lactobacillus vaccine targeting the intestinal microfold cells and dendritic cells for delivering the core neutralizing epitope of porcine epidemic diarrhea virusCytokine levels of spleen cells from immunized mice. The purified core neutralizing epitope (COE) was added into cultured spleen cells as a stimulator, and a gamma interferon (IFN-γ) and b interleukin-4 (IL-4) were then detected. Different letters indicate significant differences (p < 0.05) and the same letters indicate no significant difference (p > 0.05)Back to article page
