- HIV can return quickly after stopping treatment, but some individuals can control it for months or years without medication.
- Studies reveal that higher levels of stem cell memory CD8+ T cells correlate with delayed viral rebound.
- Certain natural killer cell types also contribute to slower HIV return.
- Two genes, DDIT4 and ZNF254, act as protective locks to keep HIV dormant, offering new targets for therapy.
- Metformin, a diabetes drug, can activate DDIT4 and suppress HIV reactivation, potentially delaying or preventing rebound.
- Research supports a 'block and lock' strategy to permanently suppress HIV, with potential applications for reducing chronic inflammation.
- The findings suggest multiple immune pathways can be leveraged to control HIV without ongoing antiretroviral therapy.
- Future possibilities include engineering stronger versions of protective genes or using metformin in clinical studies.
