Abstract: Pseudorabies virus (PRV) belongs to the α-herpesvirus subfamily, which can infect the host nervous system and establish latent infection in neurons, and PRV is an important pathogen threatening the global swine industry. Similar to other α-herpesviruses, the virion of PRV has a protein-rich inner membrane layer that links the DNA-containing capsids to the glycoprotein filled envelope layer to form the complete structure of the virion. Studies have shown that during the infection cycle of PRV, tegument proteins can play important biological functions in maintaining the stability of the morphological structure of the virus, promoting the replication and nuclear egress of the virus, participating in the secondary envelopment of the virus in the cytoplasm, and fighting against the host immune system by acting alone or interacting with other proteins. Therefore, this paper focuses on the recent research progress on the biological functions of PRV tegument proteins, in order to provide important references for the etiology and antiviral research of pseudorabies virus.
