The hidden gene in the leukemia virus can revolutionize the treatment of HIV

HTLV-1 is a pre-cancer virus known to lead to leukemia/lymphoma (ATL), which is an aggressive and deadly disease often. Although most infected individuals remain without symptoms of life, the fracture ultimately develops leukemia or other inflammatory conditions. The virus achieves long-term stability by entering a “latent” condition, during which the genetic materials are hidden inside the host’s genome with minimal activity-which evades immunity detection.

In this study, the research team, led by Professor Yuzrifom Sato of the Joint Research Center for Human Viruses, Kumamoto University, identified a specific area within the Genome HTLV-1 that works as Viral sound silencer. This sequence recruits the host copies, especially the Runx1 complex, which inhibits the genetic expression of the virus. When this silencer or mutation area is removed, the virus became more active, which increases immunity and clearance in laboratory models.

It is striking, when the HTLV-1 volume has been artificially introduced into the HIV-1-virus that causes AIDS-HIV adopts a more likely similar condition, with a decrease in identical copies and cell killing. This indicates that the silencer mechanism can be harnessed to design better HIV treatments as well.

Professor Sato said: “This is the first time that we have revealed a compact mechanism that allows the human leukemia virus to organize its concealment,” said Professor Sato. “It is a smart evolutionary tactic, and now after we understand it, we may be able to transform the tables in the treatment.”

The results offer hope not only to understand and treat HTLV-1, especially in settlement areas such as southwest Japan, but also for broader transmission infections.
