Core Tip

Core Tip: Chronic hepatitis B virus (HBV) infection is a result of immune tolerance and the presence of covalently closed circular DNA and the integrated HBV. The currently approved therapies are nucleos(t)ide analogues, interferon-alpha, and pegylated-interferon-alpha, with functional cure achieved in < 10% of patients. Disruption of the interaction between HBV or the host immune system can lead to HBV reactivation. Novel therapies include direct acting antivirals and immunomodulators. Immunomodulators may enhance/restore innate and adaptive immunity against HBV (as toll-like-receptors and retinoic acid inducible gene-1 agonist), checkpoint inhibitors, therapeutic HBV vaccines, and genetically engineered T cells to restore T cell function.
