: Linked to adult T-cell leukemia and certain neurological conditions. HTLV-2 : Associated with milder neurological disorders.

Because these viruses integrate into the host DNA, they are incredibly difficult to cure. Modern medicine manages these infections with , which targets specific enzymes like reverse transcriptase or protease to stop the virus from replicating. The "Fossil" Record in Our DNA Retrovirus

: The enzyme reverse transcriptase "back-transcribes" the viral RNA into a double-stranded DNA copy. : Linked to adult T-cell leukemia and certain

: Finally, a protease enzyme cleaves the viral proteins into their functional forms, maturing the virus so it can infect new cells. Human Health and Diseases Modern medicine manages these infections with , which

Retroviruses are responsible for several significant human diseases. The most well-known is , which attacks the immune system's T-cells and can lead to AIDS . Other notable human retroviruses include:

Retroviruses are a unique family of viruses that have fundamentally changed our understanding of genetics, evolution, and medicine. Unlike most living organisms that store genetic information as DNA, retroviruses carry their genetic blueprint as . Their name refers to their "backward" replication process: they use a specialized enzyme called reverse transcriptase to convert their RNA into DNA once they infect a host cell.
