Researchers analyzed blood samples from 75 participants across four clinical trials, identifying that higher levels of stem cell memory CD8+ T cells and specific natural killer cells delayed HIV rebound after stopping treatment.
The study shows that metformin, a common diabetes drug, can activate DDIT4 to suppress HIV reactivation, supporting a 'block and lock' strategy for long-term viral control without ongoing antiretroviral therapy.
These findings suggest multiple immune mechanisms may enable some individuals to control HIV, opening new avenues for preclinical and clinical trials aiming for durable remission and improved health for people living with HIV.

Genetic Locks DDIT4 and ZNF254 Identified as Key to HIV Latency Control and Metformin’s Therapeutic Role
Overview
A groundbreaking study identified two genes, DDIT4 and ZNF254, as genetic locks that keep HIV dormant in resting CD4+ T cells. High natural expression of these genes delays viral rebound after stopping antiretroviral therapy by creating an unfavorable environment for HIV replication and suppressing the virus epigenetically. Metformin, a safe and affordable diabetes drug, activates DDIT4, strengthening this lock and reducing chronic inflammation in people with HIV. Immune cells like stem cell memory CD8+ T cells and natural killer cells also help suppress viral rebound. Combining metformin with emerging therapies such as CAR-T cells offers a promising path toward durable HIV remission.
