In aging mice, the number of autophagosomes is significantly decreased, and pronounced defects in the structure of autophagosomes increased. Turning on the WIPI2B protein restores autophagosome formation in aged neurons.
Researchers report the ability to use sugar as food varies strongly between closely related species. The study identifies a genetic basis for this variation and could shed light on how human populations with different dietary histories may respond differently to modern, sugar rich diets.
According to a new study, a protein implicated in some neurological diseases also plays an important role in how our bodies respond to viral infections.
