What to know about Medical Research

Researchers at the University of Tennessee have identified a specific glycine-rich protein in tick saliva exosomes that facilitates feeding and pathogen transmission. The study suggests that targeting this protein could lead to the development of transmission-blocking vaccines to prevent vector-borne diseases.

What happened

Hidden tick saliva protein may help stop disease spread at source Andrew Zinin Lead Editor Few creatures inspire as much universal dislike as ticks.

Why it matters

Though small, these parasites have an enormous impact on human and animal health.

Common ground

Each year, ticks spread viruses and bacteria that infect people, livestock, wildlife, and pets around the world.

Claim 5: “When the researchers used genetic tools to silence the gene responsible for this protein... Ticks lacking the protein struggled to feed effectively and showed reduced body weight after feeding.”

DISPUTED

While the claim states ticks lacking the protein showed 'reduced body weight', one web search result specifically mentions that gene-silenced ticks 'had a different weight than the control ticks, gaining weight faster'. This directly contradicts the 'reduced body weight' part of the claim.
