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: Retrovirus

: The host cell's machinery mistakenly treats the provirus as one of its own genes, producing viral mRNA and proteins. These components assemble into new, immature viral particles that bud off from the cell. This is for informational purposes only

: Linked to adult T-cell leukemia and certain neurological conditions. HTLV-2 : Associated with milder neurological disorders. These components assemble into new, immature viral particles

: 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

Retroviruses are more than just pathogens; they are masters of genetic hijacking that have left an indelible mark on the Tree of Life. From the ongoing global challenge of HIV to the ancient "junk DNA" that shapes our biology, retroviruses continue to be a primary focus of medical research and evolutionary study.
