How tick signaling controls spread of Lyme disease and anaplasmosis

Signaling Pathways Regulating Vector Immune-Developmental Cascades

NIH-funded research Univ of Maryland, College Park · NIH-11267993

What this research studies

From a patient's view, researchers examine how black-legged ticks sense proteins in a blood meal and how those signals change the tick's immune response and development. They use the tick Ixodes scapularis in laboratory experiments combining genetic, biochemical, and microbiological methods to trace signaling pathways triggered by host factors like interferon‑gamma and adiponectin. The team tests whether disrupting extracellular signaling components in ticks reduces survival or transmission of Borrelia burgdorferi and Anaplasma phagocytophilum. The ultimate aim is to identify tick surface targets that could be turned into vaccines or other interventions to block transmission to people.

Who could benefit from this research

Good fit: People who live, work, or recreate in regions with black-legged ticks and are at risk for Lyme disease or anaplasmosis would be the most relevant candidates if this work advances to human trials.

Not a fit: People with infections already established, conditions unrelated to tick-borne pathogens, or those not exposed to tick habitats may not directly benefit from this tick-focused research.

Why it matters

Potential benefit: If successful, this could lead to vaccines or interventions that prevent ticks from transmitting Lyme disease and anaplasmosis to people.

How similar studies have performed: Laboratory and animal studies have found some promising anti-tick targets, but human vaccines to block tick-borne transmission remain largely experimental.
