Using niacin to reduce tau-related brain damage in Alzheimer's disease

Activation of the niacin receptor HCAR2 to mitigate tau pathology

NIH-funded research Indiana University Indianapolis · NIH-11102194

This study is looking at how niacin, a vitamin that can reach the brain, might help protect against damage related to Alzheimer's disease by encouraging brain cells to respond better to harmful tau proteins, and it's being tested in mice to see if it could lead to new treatments for this condition.

What this research studies

This research investigates the potential of niacin, a vitamin that can cross the blood-brain barrier, to activate a specific receptor (HCAR2) in the brain that may help protect against tau pathology associated with Alzheimer's disease. The study aims to understand how niacin can stimulate microglial cells, which play a crucial role in brain health, to respond positively to tau-induced damage. By exploring this approach, the researchers hope to find a new therapeutic strategy for treating tauopathies, which currently have no effective treatments. The research will utilize mouse models to assess the effects of niacin on tau pathology and microglial activation.

Who could benefit from this research

Good fit: Ideal candidates for this research are individuals at risk for or diagnosed with Alzheimer's disease or other tauopathies.

Not a fit: Patients with tauopathies not related to Alzheimer's disease or those who do not respond to niacin may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to new treatment options for patients suffering from Alzheimer's disease and related tauopathies.

How similar studies have performed: Previous studies have shown that niacin can have protective effects in neurodegenerative models, suggesting potential for success in this novel application.
