Despite their devastating health consequences, these diseases, which occur in some of the world's poorest and most isolated communities, often receive little attention from global funding agencies and pharmaceutical companies. They can also be difficult

parasitic worm, Schistosoma mansoni. These “Goldilocks” sites are places where genes or genetic elements can be safely inserted without damaging the organism.

The article was published in the journal Cell Reports Methods.

Using CRISPR technology, Wannaporn Ittiprasert Tanno and Paul J. Brindley, research professors of Microbiology, Immunology, and Tropical Medicine at the George Washington University School of Medicine and Health Sciences, successfully inserted a transgene into a genome safe harbor site, that when expressed in the worm, fluoresces as bright green.

The researchers say their method creates a model that could be used for testing additional gene therapies on helminth parasites with the ultimate goal of developing new drugs and vaccines to treat and prevent schistosomiasis and other similar diseases.
