Antibodies and vaginal bacteria in HPV and cervical cell changes

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

Funded at Case Western Reserve University · NIH-11164509 · Data updated 2026-11-12

This research looks at how antibodies attach to vaginal bacteria in people with HPV or different levels of cervical cell changes to better understand why some infections clear and others progress.

Who could benefit from this research

Could help

People eligible would include those with HPV infection or diagnosed cervical dysplasia (CIN1–CIN3) as well as people without HPV for comparison.

Less likely to help

People without a cervix, men, or anyone seeking immediate therapeutic treatment for cervical cancer are unlikely to receive direct medical benefit from participation.

What this research studies

If you join, researchers will collect vaginal and cervical samples from people with and without HPV and from those with normal, low-grade, or high-grade cervical changes. They will separate bacteria that have antibodies attached from those that do not, then identify which microbes and microbial functions are present using laboratory tests and genetic sequencing. The team will compare the patterns of antibody-bound and unbound bacteria across the different groups to find links with HPV infection and cervical lesion severity. Results will be used to look for markers that might predict outcomes or point to new prevention approaches.

Why it matters

Potential benefit: If successful, this work could reveal bacterial or immune markers that help predict whether HPV will clear or progress and eventually guide new prevention or treatment strategies.

How similar studies have gone: Previous research links the vaginal microbiome to HPV outcomes, but profiling antibody-bound versus unbound bacteria in the female reproductive tract is a relatively new and not yet well-tested approach.
