Investigating how oral bacteria affect immune responses in aging

CD38 signaling in aging-associated immune responses induced by oral pathogens

NIH-funded research Medical University of South Carolina · NIH-11129187

This study is looking at how certain bacteria in the mouth affect the immune system in older adults, especially focusing on a specific enzyme that might help us find new ways to treat gum disease and improve overall health as we age.

What this research studies

This research focuses on understanding the relationship between oral bacterial pathogens and immune responses in older adults. It aims to explore how the enzyme CD38, which is linked to inflammation and declines in a vital molecule called NAD+, influences these immune responses. By studying the effects of the oral pathogen Aggregatibacter actinomycetemcomitans, the research seeks to identify potential therapies that could reduce inflammatory bone loss associated with aging-related periodontitis. If successful, this could lead to new treatments that improve health and longevity for older individuals.

Who could benefit from this research

Good fit: Ideal candidates for this research are older adults experiencing periodontal disease or related inflammatory conditions.

Not a fit: Patients who are not elderly or do not have periodontal disease may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could provide new therapeutic options to reduce inflammation and improve health in older adults suffering from periodontal disease.

How similar studies have performed: Previous studies have shown promising results in targeting CD38 to improve healthspan in aged populations, indicating potential for success in this research.
