Web2 feb. 2016 · Integration is indeed an obligatory step of retroviral replication in which the viral RNA genome is first converted to double-stranded DNA by the virus-encoded reverse transcriptase, then travels across the cell cytoplasm to enter the nucleus, and is finally incorporated into the host cell genome. WebBy infecting CD4+ T cells, HIV is able to replicate predominantly in activated T cells and paralyse one of the main components of adaptive immune system. HIV can also establish latent infection in CD4+ T cells and remain invisible to CD8+ T cells and therefore replication can occur later in the infection and generate new virions.
