Who could benefit from this research

Could help

Ideal candidates are adults with aging-related vascular cognitive impairment or early-stage VCID who could participate in future clinical development.

Less likely to help

Individuals without VCID or those with advanced dementia not driven by vascular factors may derive little to no direct benefit.

What this research studies

This project aims to test a CNS-penetrant GPR39 activator to potentially prevent or slow cognitive decline in people with VCID, a common form of dementia linked to blood vessel problems. The team will use animal models and human-derived data to understand how activating GPR39 affects brain blood vessels and cognition. The study involves preclinical experiments designed to translate into future human studies, with emphasis on safety, brain delivery, and cognitive outcomes. If successful, it could lead to a new treatment option for a dementia type that currently has no specific therapies.

Why it matters

Potential benefit: If successful, the approach could slow or prevent cognitive decline in VCID and related dementias, improving daily function and quality of life.

How similar studies have gone: Previous work links endothelial enzymes and vascular signaling to cognition, and this program builds on that by targeting GPR39; results in pilot models will guide future trials.
