MIT Tests Antibody-Bred Mice on Nantucket as Lyme Disease Has Hit 15% of Residents
1 articles · Updated · Fox News · Jun 7
Summary
MIT-linked researchers are testing specially bred white-footed mice on Nantucket to see whether they can cut Lyme disease transmission by stopping ticks from picking up the bacteria.
The mice would be born with protective antibodies, a strategy aimed at breaking the infection cycle in which ticks commonly become infected after feeding on mice.
Nantucket, about 30 miles off Cape Cod, was chosen because tick-borne disease has plagued the island for decades and officials say it has one of the highest incidence rates in the country.
Roughly 15% of residents have been affected, while online reaction to the Mice Against Ticks project has split between support for a new tool and concern about possible wildlife and food-chain effects.
Could engineering mice to stop Lyme disease accidentally unleash a more deadly virus?
With human Lyme vaccines in trials, is altering an entire ecosystem to fight ticks still necessary?

Overview
The 'Mice Against Ticks' project has made major progress by using CRISPR gene editing to insert protective antibodies into mouse DNA, creating heritable immunization that passes Lyme disease resistance from one generation to the next. This breakthrough means ticks feeding on these modified mice can no longer carry the Lyme bacteria, disrupting the disease’s transmission cycle. With these advances, the team is now preparing for controlled field trials on a private island off Massachusetts. This step is essential to test the safety and effectiveness of the gene-edited mice in a real-world, contained environment before wider use.
