Researchers discovered that by blocking a specific enzyme called indoleamine-2,3-dioxygenase 1, or IDO1 for short, they could rescue memory and brain function in models that mimic Alzheimer’s disease.

NCEMS aims to ‘build a nationwide community' and address research barriers
Researchers have found certain ion channels, proteins critical for electrical signaling in the nervous system, in single celled-organisms called choanoflagellates that are the closest living relatives to animals. This rewrites the evolutionary tree of these ion channels, which were previously thought to be only be found in animals. Left: Choanoflagellate under the microscope.
