New Clues to Hepatitis B Species Restriction Could Help Build a Novel Model for Studying Infection

New clues to hepatitis B species restriction could help build a novel model for studying infection

Some 254 million people live with a chronic hepatitis B (HBV) infection that is often asymptomatic for decades, only to emerge in an advanced stage of disease that turns to fatal cirrhosis or liver cancer in nearly a million people every year. The development of effective treatments for HBV infections has been stymied because we lack a good small animal model for studying the entire viral lifecycle, host response, and disease progression.

New Clues to Hepatitis B Species Restriction Could Help Build a Novel Model for Studying Infection and Testing Therapies

More than 250 million people worldwide live with chronic hepatitis B (HBV), yet there is still no accessible animal model for studying the disease or testing novel therapies. Researchers have now proven that mouse liver cells can support the formation of the HBV genetic template required for chronic infection, overturning a long-standing view in the field. The study may accelerate the development of a much-needed mouse model for studying HBV's i…
