N protein expression in jejunum tissues of the piglets infected with PEDV Control group of piglets of jejunum immunohistochemistry was A, B, C. Infected group of piglets of jejunum immunohistochemistry was D, E, F (bar=20 μm)"

Fig. 2

Identification of differentially expressed genes A. Volcano plots of differentially expressed genes between the mock-infected and PEDV-infected groups. The red, blue and gray dots represent up regulated, down regulated and nosing genes, respectively, in the PEDV-infected group compared with the mock infected group. B. Heatmap showing the expression levels of the differentially expressed genes. Columns represent individual samples (1, 2 and 3 were infected group; 4, 5 and 6 were control group) and rows indicate genes with significant expression differences between the two groups"
