Retrovirus Life Cycles

JoVE 10825

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the retrovirus to replicate. New retroviral RNA is transported to the cytoplasm, where it is translated into proteins that assemble new retroviruses. Particular drugs have been developed to fight retroviral infections. These drugs target specific aspects of the life cycle. One class of antiretroviral drugs, fusion inhibitors, prevents the entry of the retrovirus into the host cell by inhibiting the fusion of the retrovirus with the host cell membrane. Another class of antiretrovirals, reverse transcriptase inhibitors, inhibits the reverse transcriptase enzymes that make DNA copies of the retroviral RNA genome. Reverse transcriptase inhibitors are competitive inhibitors; during the process of reverse transcription, the drug molecules are incorporated into the growing DNA strand instead of the usual DNA bases. Once incorporated, the drug molecules block further progress by the r
