The first steps of endocytosis faltered in astrocytes expressing ApoE4, but pumping in PICALM reversed the problem. A new study places two Alzheimer’s risk factors into the same cellular mechanism.
Three amino acid substitutions in the Aβ sequence accelerate BACE cleavage of APP and ramp up Aβ production in rats and mice. The mice can serve as better controls for mutant APP knock-ins already in use.
Researchers have devised a way to measure how long ago a reporter transcript was made. It allows them to detect distinct transcriptional events within a cell.
Armed with snazzy new hardware, scientists solve protein structures to a resolution of 1.22Å. Cryo-EM now rivals X-ray crystallography.
