Washington University Researchers Engineer Hookworms to Deliver Therapeutic Proteins in Human Intestines

Researchers at the Washington University School of Medicine have genetically modified human hookworms to function as internal delivery systems for therapeutic agents. The study details how scientists repurposed the parasite to produce and secrete specific proteins directly into the host’s intestine, utilizing the organism’s natural ability to inhabit the human gut for extended periods.

The research team engineered the hookworms to act as biological factories, allowing the parasites to synthesize and release medication while remaining attached to the intestinal wall. By modifying the genetic makeup of the hookworm, the scientists established a mechanism that enables the parasite to coexist with the host while performing a targeted delivery function. This development marks a shift in how researchers approach long-term drug administration, as the hookworm’s biological persistence provides a stable environment for the continuous release of therapeutic compounds.
