Prion aggregates are associated with diseases including Alzheimer’s, Huntington’s and Parkinson’s. It’s believed that when prion aggregates arise, cells cannot get rid of them. A recent work from the lab of Tricia Serio, professor and head of the MCB department, showed however that yeast cells can clear themselves of prion aggregates at an increased temperature.… Read More »

In humans, yeast and other eukaryotes, a group of proteins called the Target of Rapamycin Complex I (TORC1) promote cell growth and increase metabolic activity when nutrients are plentiful. Previous studies have shown how molecules that contain the nutrient nitrogen – which is needed to make proteins – activate TORC1. However, it is not clear… Read More »
