Histopathological changes in piglets 7 days post-inoculation. (A) 1: livers of piglets in the normal control group, ×400; 2: livers of piglets inoculated with HEV, ×400; 3: livers of piglets injected with shRNA-scrambled expression plasmid 24 h pre-inoculation, ×200; 4–7: livers of piglets separately injected with shRNA-RdRp-1–4 expression plasmids 24 h pre-inoculation, ×400. (B) 1: spleens of piglets in normal control group, ×200; 2: spleens of piglets inoculated with HEV, ×200; 3: spleens of piglets injected with shRNA-scrambled expression plasmid 24 h pre-inoculation, ×200; 4–7: spleens of piglets separately injected with shRNA-RdRp-1–4 expression plasmids 24 h pre-inoculation, ×200. Tissues were stained with hematoxylin and eosin.
