En personas con defensas bajas puede causar enfermedades graves, y los tratamientos actuales tienen efectos adversos y no siempre alcanzan. Que exista un punto concreto que frena la reproducción da a los científicos un blanco para diseñar fármacos más precisos.

The team led by Raj Gaji, assistant professor of parasitology at the Virginia-Maryland College of Veterinary Medicine working in the Center for One Health Research, identified a protein the team named DDP that helps Toxoplasma gondii build its offspring. When researchers switched it off, the parasites stopped multiplying entirely.","pubDate":"Thu, 22 Oct 2026 16:00:01 EDT","url":"https://phys.org/news/2026-10-parasite-humanity-key-protein-disabled.html"},"indexado":"2026-10-22T20:02:16.380Z"}}
