Abstract: Importantly, the polymorphic change
L63P, although not conferring inhibitor resistance by itself, provided a significant replication benefit to both mutant viruses, particularly under drug pressure, and may reveal a far-reaching compensating power of polymorphic changes.
Abstract: The role of drug pressure on the replicative capacity of
protease inhibitor-resistant HIV-1 variants and the contribution of a common amino-acid polymorphism in the
protease gene (
L63P) to this process were investigated.
