PlzA protein and how Lyme bacteria survive in ticks and mammals

PlzA, cyclic-di-GMP and the enzootic cycle for Lyme disease

NIH-funded research Virginia Commonwealth University · NIH-11231225

Researchers will look at how a bacterial protein called PlzA helps Lyme bacteria live in ticks and mammals to better protect people at risk of Lyme disease.

What this research studies

Scientists will change specific surface parts of the PlzA protein based on its 3D structure to see how those changes affect its shape, binding to the signaling molecule c-di-GMP, and interactions with RNA and other proteins. They will test these altered proteins in biochemical experiments and then make modified B. burgdorferi bacteria that carry those changes. Those engineered bacteria will be studied in ticks and mammal models to find out whether the changes change infection or transmission. This work is laboratory and animal-focused and does not directly enroll patients.

Who could benefit from this research

Good fit: This project does not enroll people; its results will be most relevant to people at risk for or living with Lyme disease.

Not a fit: Patients seeking immediate treatments or direct clinical care should not expect personal benefit from this lab-and-animal research.

Why it matters

Potential benefit: If successful, this work could reveal targets to block the bacterium from establishing infection or being passed by ticks.

How similar studies have performed: Prior studies have revealed PlzA's atomic structure and some functions, so using targeted mutations and testing effects on transmission builds on established findings but applies them in new functional experiments.
