Duck HMGB2 Mediates Signaling Pathways in the Innate Immunity of Hosts Against Viral Infections.

ABSTRACT: High-mobility group box 2 (HMGB2) belongs to the HMG-box family that participates in a variety of biologic processes. Recent studies have suggested that HMGB2 plays an important role in the innate immunity of fish. Cherry Valley duck is the main duck bred for meat consumption in China, but there is limited research available on the impact of duck HMGB2 (duHMGB2) in antiviral innate immunity. Here, duHMGB2 genes were first cloned and analyzed from the spleen of Cherry Valley ducks. We show that duHMGB2 is widely distributed in most tissues of healthy ducks, and duHMGB2 was differentially expressed in three organs (the spleen, brain, and lung) of ducks during different viral infections. duHMGB2 is mainly expressed in the nucleus of duck embryo fibroblast (DEF) cells.
