PNU-120596 for HIV-related thinking and memory problems
Positive allosteric modulator PNU-120596 to treat HIV-associated neurocognitive disorders
This project tests whether PNU-120596, a drug that boosts a brain receptor, can protect the brain and reduce thinking and memory problems in people living with HIV.

What this research studies
Researchers are studying a drug called PNU-120596 that enhances the α7 nicotinic acetylcholine receptor to protect brain cells from damage linked to HIV and the viral protein Tat. The work uses lab experiments and mice engineered to produce Tat in the brain to track inflammation, neuron health, and viral reactivation. Scientists will also examine how the drug affects HIV replication and the cellular mechanisms behind its protective effects. If the lab and animal results remain promising, the findings could guide later human testing.
Who could benefit from this research
Good fit: People living with HIV who have HIV-associated neurocognitive disorders or noticeable problems with memory, attention, or thinking would be the intended candidates for follow-up clinical work.
Not a fit: People without HIV or whose cognitive issues are caused by other conditions (for example Alzheimer's disease or stroke) are unlikely to benefit from this treatment approach.
Why it matters
Potential benefit: If successful, this approach could lessen HIV-associated cognitive problems and reduce viral reactivation in the brain.
How similar studies have performed: Early lab and mouse studies from this team showed that α7 nAChR positive allosteric modulators like PNU-120596 improved brain pathology and reduced HIV reactivation, but human testing has not yet been done.
