What this research studies

This multi-center project focuses on the blacklegged tick (Ixodes scapularis) and the internal signaling pathways that shape its development, metabolism, and immune responses. Scientists will study how molecules from mammals (like cytokines) trigger tick receptors and change the tick's ability to harbor and transmit Borrelia (Lyme) and Anaplasma pathogens. The team uses molecular tools including RNA interference to silence specific tick receptors and extracellular molecules and watches how that affects tick feeding and pathogen transmission. Results from lab and animal experiments will guide ideas for new ways to interrupt ticks so they are less likely to infect people.

Who could benefit from this research

Good fit: Ideal participants would be people who live or work in tick‑endemic areas and are willing to provide samples or take part in related prevention studies at collaborating research sites.

Not a fit: People already living with long‑term symptoms of Lyme disease are unlikely to see direct short‑term clinical benefits from this basic tick biology research.

Why it matters

Potential benefit: If successful, this research could lead to new approaches that prevent ticks from feeding or passing on Lyme disease and anaplasmosis, reducing human infections.

How similar studies have performed: Prior laboratory work by the team has shown that knocking down certain tick receptors with RNA interference can disrupt tick feeding and reduce pathogen transmission, but translating those findings into human prevention tools is still early.
