Hepatitis

No cure for hepatitis B and D without targeting integrated viral DNA?

Nature Reviews Gastroenterology & Hepatology volume 15, pages 195–196 (2018)Cite this article

Subjects

RNA interference (RNAi) is a novel concept to target transcripts derived from HBV covalently closed circular DNA. The study by Wooddell et al. investigates the RNAi-based therapy ARC-520 in patients and chimpanzees with chronic HBV infection and uncovers HBV DNA integration as a crucial source of hepatitis B surface antigen, which has not been considered in current strategies to accomplish HBV cure.
