Creating a humanized mouse model to study gum disease

Official title: Humanized mouse model of periodontitis

Funded at Nova Southeastern University · NIH-10976283 · Data updated 2026-11-12

This study is looking at how a specific protein called Semaphorin 4D affects gum disease and bone loss by using special mice that can have human immune cells, which helps researchers learn more about the disease and find new ways to treat it.

Who could benefit from this research

Could help

Ideal candidates for this research are adults over 21 years old who are experiencing or at risk for periodontitis.

Less likely to help

Patients with conditions unrelated to periodontitis or those who are not adults may not benefit from this research.

What this research studies

This research aims to develop a humanized mouse model to investigate the role of Semaphorin 4D (Sema4D) in periodontitis, a serious gum disease. By using advanced immunodeficient mice that can host human immune cells, researchers will explore how Sema4D affects bone loss and inflammation associated with gum disease. The study will involve transplanting human hematopoietic stem cells into these mice to create a model that closely mimics human responses to periodontitis. This approach allows for a better understanding of the disease mechanisms and potential therapeutic targets.

Why it matters

Potential benefit: If successful, this research could lead to new treatments for periodontitis that effectively prevent bone loss and inflammation.

How similar studies have gone: Previous research has shown success in using humanized mouse models to study various diseases, indicating a promising approach for this investigation.
