How a fat called ceramide in tiny brain particles may worsen Alzheimer’s

Function of ceramide in extracellular vesicle-mediated neurodegenerative disease

NIH-funded research University of Kentucky · NIH-11297635

What this research studies

Researchers will study extracellular vesicles (tiny particles) released by brain support cells that carry ceramide and bind to amyloid beta, a hallmark of Alzheimer’s. They will identify the enzymes that make ceramide and explore why blocking one enzyme helped male mice but not females. Lab experiments and animal tests will be used to see if preventing these ceramide-rich particles from forming can protect neurons and improve memory. The team will also work toward drug approaches that target the ceramide pathway with attention to sex-specific effects.

Who could benefit from this research

Good fit: Likely candidates for future trials would be people with Alzheimer’s disease or mild cognitive impairment who are willing to consider experimental treatments targeting ceramide pathways.

Not a fit: People without Alzheimer’s, those whose cognitive problems come from other causes, or individuals with very advanced disease may not benefit from these approaches.

Why it matters

Potential benefit: If successful, this work could lead to new drugs that block ceramide-containing brain particles and slow or prevent neuron loss and memory decline in Alzheimer’s.

How similar studies have performed: Early lab and mouse studies showed that blocking the enzyme nSMase2 reduced Alzheimer’s pathology and improved memory in male mice, but the approach is still novel and not yet proven in humans.
