What to know about Medical Breakthroughs

Researchers at the University of Wollongong have used advanced imaging to observe how chaperone proteins Hsp70 and Hsp90 collaborate to ensure proteins fold correctly. The study, published in Science Advances, provides insights into the molecular mechanisms that prevent protein misfolding, which is linked to neurodegenerative diseases.

Scientists watch, molecule by molecule, as cell helpers rescue problem proteins Swati Mestri Scientific Editor Robert Egan Senior Editor University of Wollongong (UOW) scientists have uncovered, for the first time, exactly how two of the cell's "helper"…

Why it matters

Using advanced imaging techniques capable of tracking individual protein molecules in real time, the team from UOW's Molecular Horizons watched two chaperone proteins, heat shock protein 70 (Hsp70) and Hsp90, in action as they worked together to ensure that…

Common ground

Special "helper" proteins, called chaperones, are the cell's first line of defense.
