Targeting Galectin-9 to Reduce Persistent HIV
Modulation of Galectin-9 to Target HIV Persistence
This project tries blocking a protein called galectin-9 to help people with HIV whose virus remains hidden despite treatment.

What this research studies
Researchers are studying a protein called galectin-9 that appears to help HIV hide in CD4+ T cells even when people are on antiretroviral therapy. They will measure galectin-9 levels in blood and tissues, examine how it overlaps with sites of HIV, and test whether blocking galectin-9 changes the amount of hidden HIV using lab tests and animal models. The team will use human blood and tissue samples as well as humanized mouse experiments to track HIV DNA and RNA in CD4+ T cells. Their methods aim to show whether inhibiting galectin-9 could lower the long-lived viral reservoir.
Who could benefit from this research
Good fit: Ideal candidates would be adults living with HIV who are on stable ART with suppressed viral loads and willing to provide blood or tissue samples.
Not a fit: People not on ART, those with uncontrolled viral loads, or those unwilling to give samples are unlikely to be helped or enrolled.
Why it matters
Potential benefit: If successful, this work could lower the amount of hidden HIV in the body and move closer to a functional cure.
How similar studies have performed: Laboratory and animal studies show galectin-9 can reactivate or influence HIV latency, but this approach has not yet proven beneficial in people.
