Persistence of mutations during replication of an HIV library containing combinations of selected protease mutations.

Abstract excerpt

It has been known that, in some cases, accumulation of specific mutations in HIV-1 protease leads to multi-protease inhibitor (PI) resistance. We examined the persistence of mutations detected in HIV-1 clinical isolates cross-resistant to the current PIs using an HIV-1 protease restricted library (HXB2 protease in an HIV-1(NL4-3) background) in the absence of protease inhibitors. The virus library contained...
