This study firstly reported that ALV-J could induce a mixed Th1/Th2 cytokine response by elevating levels of both interleukin-2 (IL-2) and IL-10 during the late stages of ALV-J infection in vivo.
This study firstly reported that different ALV subgroups or strains up-regulated chicken IFN regulatory factor 3 (ChIRF-3) promoter activity, suggesting that ALV infection could trigger Type I IFNs pathway in vitro.
This study firstly reported that ChIFNα restrained ALV replication as measured by decreases in viral protein p27 levels and mRNA expression.
