Antibodies and vaginal bacteria in HPV-related cervical changes

Official title: Antibody bound bacteria during HPV infection and cervical dysplasia

Funded at Case Western Reserve University · NIH-11398821 · Data updated 2026-11-12

This project looks at whether antibodies bind different vaginal bacteria in women with HPV or cervical cell changes to understand why some women develop more serious lesions.

Who could benefit from this research

Could help

Women who can provide vaginal samples and have known HPV status and cervical pathology results—ranging from normal findings to low-grade or high-grade cervical intraepithelial neoplasia—would be eligible.

Less likely to help

People without a cervix, those unable to provide vaginal samples, or those not within the study's recruitment area would not be eligible and would not benefit directly.

What this research studies

If you join, researchers will collect vaginal samples and cervical pathology results from women with and without HPV and with normal tissue, low-grade, or high-grade lesions. They will separate bacteria that are coated with antibodies from those that are not, identify which microbes are present, and analyze their functions using laboratory tests and sequencing. The team will compare the proportion and activity of antibody-bound versus unbound bacteria across these groups to find patterns linked to persistent HPV or progression to more severe cervical disease. Findings could help explain how immune responses and the vaginal microbiome interact in cervical health.

Why it matters

Potential benefit: This could identify microbial or immune markers that predict HPV persistence or progression, helping guide future prevention or treatment strategies.

How similar studies have gone: Prior research has linked the vaginal microbiome to HPV outcomes, but systematically studying which bacteria are bound by antibodies in the reproductive tract is a novel approach with limited prior data.
