When the cell digests itself: How inherited neurodegenerative diseases develop

Our cells are crisscrossed by a system of membrane tubes and pockets called the endoplasmic reticulum (ER). It is crucial for the production of biomolecules and is continuously built up and degraded. Degradation, known as ER-phagy, is promoted by the protein ubiquitin, which controls many processes in the cell. If the proteins involved in ER-phagy are defective, neurodegenerative diseases result. This has been discovered by an international research team led by Goethe University Frankfurt (as part of the EMTHERA research cluster) and Jena University Hospital and published in two papers in the renowned journal Nature.
