Understanding how Trichomonas vaginalis affects vaginal bacteria and immune response

RP-Riestra/Sussman: Investigating the Antibacterial and Immune Modulating Effects of Trichomonas Vaginalis Infection and Pyroptosis

NIH-funded research San Diego State University · NIH-11172387

This study is looking at how the parasite that causes trichomoniasis affects the good bacteria in the vagina that help keep it healthy, and it’s especially important for women, particularly those from racial and ethnic minority groups who are more affected by this infection.

What this research studies

This research investigates the impact of the sexually transmitted parasite Trichomonas vaginalis on beneficial vaginal bacteria, specifically Lactobacillus species. It aims to uncover the molecular mechanisms by which T. vaginalis kills these protective bacteria and how this process may trigger an inflammatory response known as pyroptosis. By using advanced techniques like live/dead staining and pharmacological inhibitors, the study will explore the interactions between the parasite and the bacteria, as well as the potential antibacterial effects of pyroptosis. This research is particularly focused on the implications for women's health, especially among racial and ethnic minorities who are disproportionately affected by trichomoniasis.

Who could benefit from this research

Good fit: Ideal candidates for this research are women who are diagnosed with trichomoniasis or are experiencing symptoms related to bacterial vaginosis.

Not a fit: Patients who do not have a history of trichomoniasis or related vaginal infections may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to new strategies for preventing and treating bacterial vaginosis and other related infections in women.

How similar studies have performed: While the specific interactions between T. vaginalis and vaginal bacteria are understudied, related research on inflammatory responses and bacterial interactions has shown promising results.
