Investigating how blocking a specific receptor affects HIV reservoirs in the brain and body after stopping treatment.

Effects of CSF1R Blockade on Repopulation of SIV Reservoirs from the CNS to the Periphery After Antiretroviral Therapy Interruption

NIH-funded research Boston College · NIH-10872289

This study is looking at how a certain immune cell in the brain can hide HIV and cause it to come back after treatment stops, and it’s testing a drug that might help get rid of these hidden virus spots in monkeys to find better ways to keep HIV from returning in people.

What this research studies

This research explores the role of a specific type of immune cell in the brain that can harbor HIV and potentially cause the virus to rebound after treatment is stopped. By using a drug that blocks the colony-stimulating factor 1 receptor (CSF1R), the study aims to eliminate these viral reservoirs in the central nervous system (CNS) of macaques. The researchers will observe the effects of this treatment both early and late during antiretroviral therapy (ART) to understand how it impacts the spread of the virus once therapy is interrupted. The findings could provide insights into new strategies for preventing HIV rebound in patients.

Who could benefit from this research

Good fit: Ideal candidates for this research are individuals living with HIV who are currently on antiretroviral therapy and may be at risk of treatment interruption.

Not a fit: Patients who are not living with HIV or those who have not been on antiretroviral therapy may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to new treatments that prevent HIV from rebounding after stopping antiretroviral therapy.

How similar studies have performed: Previous research has shown promise in targeting similar immune cells to reduce viral reservoirs, indicating potential for success in this approach.
