Abstract: The major HBV lamivudine (LMV)-resistant mutations in the
polymerase gene within the
reverse transcriptase (
rt) region at
rtM204V or
rtM204I are associated with changes in the overlapping
envelope gene products, in particular, the gene encoding
small envelope protein (
s) at
Abstract: We have demonstrated that the LMV resistance mutations corresponding to
sW196L/S inhibited secretion of HDV particles, while changes corresponding to
sI195M did not affect secretion.
