Taking out the trash is essential for brain health

Researchers have identified a protein called Wipi3 that is essential for cellular waste disposal via the alternative autophagy system. Deletion of Wipi3 in the brains of mice causes growth and motor defects attributed to neuronal accumulation of iron, resulting in neurodegeneration. However, over-expression of another alternative autophagy protein, Dram1, reverses the effects in Wipi3 deficiency, and may represent a novel treatment for neurodegenerative diseases.
