The substitution of isoleucine to leucine at amino acid 97 (I97L) in the core region of the hepatitis B virus (HBV) seems to reduce its potency, decreasing the efficiency of both infection and the synthesis of the virus’ covalently closed circular (ccc) DNA, reports a new study presented at The Liver Meeting Digital Experience by the American Association for the Study of Liver Diseases (AASLD 2020).
