Cathelicidin CATH-B1 Inhibits Pseudorabies Virus Infection via Direct Interaction and TLR4/JNK/IRF3-Mediated Interferon Activation

Although the antiviral activity of cathelicidins could be explained by direct interfering with the viral infection and regulating host antiviral response, the specific mechanism of cathelicidins regulating host antiviral response and interfering with pseudorabies virus (PRV) infection remains elusive. In this study, we investigated the multiple roles of cathelicidin CATH-B1 against PRV infection.
