Reducing brain inflammation in people with HIV who use cocaine

Development of NLRP3 inhibitors for HIV-associated neuroinflammation in cocaine use.

NIH-funded research University of Texas El Paso · NIH-11159533

This project is testing new drugs that block a key inflammation switch in the brain to help people with HIV who use cocaine keep their thinking and movement skills.

What this research studies

Researchers are designing drugs that block the NLRP3 inflammasome, a protein complex that drives brain inflammation in HIV. They will use lab-grown cells and animal models that mimic HIV infection and cocaine exposure to see whether these drugs lower inflammatory signals like IL-1β and prevent neuron death. The team will measure markers such as caspase-1 activation, inflammatory cytokines, and signs of cell damage to judge drug effects. Positive results would support moving these treatments toward human testing.

Who could benefit from this research

Good fit: People living with HIV who have cognitive or motor symptoms and a history of cocaine use would be the primary candidates for related future trials.

Not a fit: People whose cognitive problems are unrelated to inflammation or who do not have a history of cocaine use may not benefit from this approach.

Why it matters

Potential benefit: If successful, these drugs could reduce brain inflammation and help protect thinking, memory, and motor skills in people with HIV who use cocaine.

How similar studies have performed: NLRP3 inhibitors have shown promise in animal models of other neuroinflammatory conditions, but applying them specifically to HIV plus cocaine-related brain injury is a newer approach.
