NIH-funded research R01 grant

Understanding how a specific bacteria affects gum disease

Official title: Regulatory Mechanisms Controlling P. gingivalis Surface Structures

Funded at Ada Forsyth Institute, INC. · NIH-11082997 · Data updated 2026-11-12

This study is looking at how a bacteria called Porphyromonas gingivalis, which is known to cause gum disease, creates its protective outer layer and how it becomes more harmful, with the goal of understanding how it affects your oral health.

Who could benefit from this research

Could help

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

Less likely to help

Patients who do not have periodontal disease or are under 21 years old may not benefit from this research.

What this research studies

This research investigates the mechanisms by which Porphyromonas gingivalis, a bacteria linked to periodontal disease, produces its protective capsule and membrane lipids. By studying the genetic and biochemical pathways involved, the research aims to uncover how this bacteria transitions to a more virulent state, potentially leading to gum disease and related health issues. The approach includes manipulating specific RNA molecules and proteins that regulate these processes, providing insights into bacterial behavior and its impact on human health.

Why it matters

Potential benefit: If successful, this research could lead to new strategies for preventing or treating periodontal disease and its associated health complications.

How similar studies have gone: Previous research has shown that understanding bacterial mechanisms can lead to significant advancements in treating related diseases, suggesting a promising avenue for this investigation.
