Investigating how nicotine affects brain inflammation in people with HIV-1

Nicotine and NLRP3 Inflammasome in HIV-1-Associated CNS Inflammation

NIH-funded research Icahn School of Medicine at Mount Sinai · NIH-11086711

This study is looking at how smoking might affect brain inflammation and thinking skills in people with HIV-1, using samples from tonsils, brain tissue, and special lab-grown cells to see if nicotine makes things worse.

What this research studies

This research explores the relationship between nicotine use and inflammation in the brains of individuals infected with HIV-1. It focuses on understanding how nicotine may activate the NLRP3 inflammasome, a key player in neuroinflammation, which could contribute to cognitive decline in people with HIV-1. The study will utilize human tonsil samples, induced pluripotent stem cell-derived microglia, and a specialized mouse model to track changes in inflammation. Additionally, it will analyze brain samples from deceased individuals to compare inflammation markers between smokers and non-smokers with HIV-1.

Who could benefit from this research

Good fit: Ideal candidates for this research are individuals living with HIV-1 who also have a history of smoking.

Not a fit: Patients who are not infected with HIV-1 or do not have a history of smoking may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved understanding and potential treatments for cognitive decline in HIV-1 patients who smoke.

How similar studies have performed: Previous research has indicated that targeting neuroinflammation may improve cognitive outcomes in HIV-1 patients, suggesting potential success for this approach.
