Achieving a functional cure for chronic hepatitis B (hepatitis B virus) requires overcoming challenges like persistent viral DNA and immune dysfunction. Novel strategies targeting the viral lifecycle and boosting immune responses are crucial for a cure.
Area of Science:
- Hepatology
- Virology
- Immunology
Background:
- Chronic hepatitis B virus (HBV) infection impacts over 300 million globally, leading to liver failure and cancer.
- Current nucleoside analogue treatments suppress HBV DNA but rarely achieve a functional cure.
Purpose of the Study:
- To review novel therapeutic approaches for achieving a functional cure in chronic hepatitis B.
- To address the limitations of current suppressive therapies.
Main Methods:
- Focus on strategies targeting the HBV lifecycle.
- Review of approaches aimed at modulating the host immune system.
Main Results:
- Current therapies fail to eliminate persistent covalently closed circular DNA (cccDNA).
- Immune exhaustion limits the effectiveness of existing treatments.
- Novel approaches are being developed to overcome these obstacles.
Conclusions:
- A functional cure for chronic HBV requires addressing both viral persistence and immune dysfunction.
- Targeting viral replication and enhancing immune surveillance are key strategies for a cure.
