Non-suppressible HIV viremia sustained by clonally expanded CD4+ T cells harbouring a genomically defective provirus with an immune-evasive protein expression profile

This study explored why small amounts of HIV can still be found in some people even when treatment is working well and the virus is largely controlled. Researchers investigated whether certain infected immune cells could continue producing viral material despite long-term treatment.

The study found that a group of immune cells had multiplied and formed large populations carrying damaged forms of HIV. Although these viral forms were incomplete and unable to produce fully functional virus particles, they could still make some viral proteins. These proteins appeared to help the infected cells avoid being recognised and removed by the immune system.

As a result, these cells were able to survive for long periods and continue contributing to low levels of virus detected in the blood. The findings suggest that incomplete forms of HIV may still play an important role in maintaining viral activity, even when treatment is effective.

Overall, the research provides new insight into how HIV persists in the body despite treatment. Understanding these hidden sources of viral activity could support future efforts aimed at long-term control and the development of strategies that move closer towards an HIV cure.
