New protein discovery opens doors to novel therapies for neglected tropical diseases.

A new study by researchers from Ruhr University Bochum and the University of Würzburg may pave the way for life-saving treatments against tropical diseases like African sleeping sickness, Chagas disease, and leishmaniasis.

At the focus of this breakthrough is the identification of membrane proteins in glycosomes—specialized cell organelles found only in parasites such as Trypanosoma brucei, the pathogen responsible for African sleeping sickness. By cataloging these proteins with unprecedented accuracy, the team has opened up new possibilities for targeted drug development.

“Some of these glycosomal membrane proteins are parasite-specific and significantly different from those in human cells,” explains Professor Ralf Erdmann from Ruhr University Bochum. “This makes them ideal candidates for therapeutic intervention.”

The study, published in Cell Reports on May 27, 2025, used advanced subcellular proteomics to identify 28 glycosome membrane proteins, many of which were previously unknown. Notably, the researchers discovered TbPEX15, a membrane anchor that plays a key role in protein import into the glycosome. This protein is structurally different from its human counterpart, making it a particularly promising target for new drugs.

Co-author Professor Bettina Warscheid emphasized the broader potential of the discovery. “Beyond identifying drug targets, our work offers new insights into how these parasites survive and interact with their environment,” she said. “It’s a valuable resource for ongoing biomedical research.”

With over 12 million people worldwide affected by these tropical diseases—most of whom live in under-resourced regions—this research represents a crucial step toward equitable healthcare solutions. It not only supports global efforts in parasite biology but also strengthens the scientific foundation for future drug discovery.

This study stands as a testament to how molecular biology can deliver hope for diseases long overlooked in mainstream medicine.
