Infection (NC group) with E. maxima increased the gene expression of TNFSF15 (p = 0.006, 2.9 × 10−3 to 2.3 × 10−2), IL-1β (p = 0.001, 1.9 × 10−3 to 4.9 × 10−3), and IL-8 (p = 0.022 6.3 × 10−3 to 2.0 × 10−2) in the distal jejunum compared to that of the CON group (Figures 6A, B, D). Here, TNFSF15 is linked to infection.
