Killer worm's spit supercharges healing

A molecule produced by a Thai liver parasite could be the solution to non-healing wounds, say Australian scientists.

The molecule is granulin, one of a family of protein growth factors involved with cell proliferation.

“It’s produced by a parasitic liver fluke, Opisthorchis viverrini, which originally came to our attention because it causes a liver cancer that kills 26,000 people each year in Thailand,” says parasitologist Dr Michael Smout.
