Investigating how a specific protein affects brain health in people with HIV

Role of Monocyte Delta Like-4 (Dll4) in HIV-Associated Cerebral Small Vessel Disease

NIH-funded research University of Rochester · NIH-10837487

This study is looking at how a protein called Dll4 affects brain blood vessels and thinking skills in people with HIV, especially those dealing with inflammation, to help us understand more about cerebral small vessel disease.

What this research studies

This research focuses on understanding the role of a protein called Delta like-4 (Dll4) in the development of cerebral small vessel disease (CSVD) and its effects on cognitive function in individuals living with HIV. The study examines how Dll4, which is typically found in blood vessel cells, can be expressed by immune cells under inflammatory conditions, particularly in the context of ongoing inflammation in HIV patients receiving treatment. By analyzing both laboratory models and clinical samples, the research aims to uncover the mechanisms by which Dll4 influences brain blood vessel function and cognition.

Who could benefit from this research

Good fit: Ideal candidates for this research are individuals living with HIV who are experiencing cognitive difficulties or have been diagnosed with cerebral small vessel disease.

Not a fit: Patients who are not living with HIV or those without cognitive impairments related to cerebral small vessel disease may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to new therapeutic strategies to protect brain health and improve cognitive function in people living with HIV.

How similar studies have performed: While the specific role of Dll4 in this context is being explored, similar research has shown that targeting inflammatory pathways can lead to improvements in vascular health and cognitive function in other conditions.
