Cells, serum samples, and experimental animals
The SP2/0 and Sf-21 cells used in this study were maintained in our
laboratory. ASFV (Pig/HLJ/2018) infected porcine alveolar macrophages
(PAM), tissues samples including the spleens, tonsils, and gastrohepatic
lymph nodes from ASFV infected pigs, and anti-ASFV positive sera were
obtained from the National High Containment Laboratory for Animal
Diseases Control and Prevention, Harbin, China. The details of animal
experiments were described previously (Zhao et al., 2019; Chen et al.,
2020). Six-week-old female mice were purchased from Changsheng company
Liaoning Province and kept in the experimental animal facility at Harbin
Veterinary Research Institute.
