Our work highlights the role of HIV-1 unintegrated viral DNA in viral replication. A virus, resistant to strand-transfer inhibitors, has been selected in vitro . This virus highlights a mutation in the 3'PPT region and not in the integrase gene. This mutation modifies the reverse transcription step leading to the accumulation of 1-LTR circles and not the linear DNA. This accumulation of 1-LTR circles leads to viral replication without integration of the viral genome.
