摘要
Chronic hepatitis B virus(HBV)infection is an international health problem with extremely high mortality and morbidity rates.Although current clinical chronic hepatitis B(CHB)treatment strategies can partly inhibit and eliminate HBV,viral breakthrough may result due to non-adherence to treatment,the emergence of viral resistance,and a long treatment cycle.Persistent CHB infection arises as a consequence of complex interactions between the virus and the host innate and adaptive immune systems.Therefore,understanding the immune escape mechanisms involved in persistent HBV infection is important for designing novel CHB treatment strategies to clear HBV and achieve long-lasting immune control.This review details the immunological and biological characteristics and escape mechanisms of HBV and the novel immune-based therapies that are currently used for treating HBV.
