Stopping HIV from Hiding in the Brain and Spreading to the Body

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-11128574

This work explores how a specific treatment might prevent HIV from hiding in the brain and then re-emerging in the body, even after antiretroviral therapy.

What this research studies

Even with effective HIV medication, the virus can remain hidden in certain cells within the brain. These hidden virus 'reservoirs' can cause the virus to rebound if medication is stopped or if there are temporary viral increases. Our team believes that a specific type of immune cell in the brain, called perivascular macrophages (PVMs), acts as a major hiding spot for HIV. We are testing a medication that targets these PVMs to see if it can stop the virus from hiding there and then spreading to other parts of the body.

Who could benefit from this research

Good fit: This foundational research is for individuals interested in the underlying biology of HIV persistence and future therapeutic strategies for HIV eradication.

Not a fit: Patients seeking immediate clinical treatment or direct participation in a human clinical trial would not directly benefit from this early-stage animal model research.

Why it matters

Potential benefit: If successful, this work could lead to new strategies to eliminate HIV reservoirs in the brain, potentially preventing viral rebound and moving closer to a cure.

How similar studies have performed: Previous work has identified these brain cells as a target for HIV, and this approach builds on that understanding to test a novel intervention strategy.
