Who could benefit from this research

Could help

People with syphilis who have lesions from which Tp can be sampled under approved ethical guidelines.

Less likely to help

Individuals whose samples do not yield viable Tp data or who are not candidates for lesion sampling may not benefit.

What this research studies

This project uses a cutting-edge single-cell transcriptomics approach to study Treponema pallidum directly from human syphilis lesions, aiming to capture how the bacterium behaves during natural infection. Researchers will optimize and apply the technique to obtain high-quality RNA from very few bacterial cells present in clinical samples. The study focuses on Tp gene activity related to invasion, survival, and replication within the human host, beyond what traditional animal or in vitro models can reveal. Outcomes may illuminate key bacterial pathways and potential targets for new treatments or diagnostics. Participation would involve patients with syphilis contributing lesion samples under appropriate ethical approvals.

Why it matters

Potential benefit: Findings could lead to better understanding of Tp behavior in humans and inform development of improved therapies or diagnostics for syphilis.

How similar studies have gone: Preliminary single-cell approaches have shown promise in other hard-to-study pathogens, supporting potential success here.
