A hidden neuron 'gatekeeper' may shape Alzheimer's buildup of amyloid-beta

Brain cells are constantly swallowing material from the fluid that surrounds them—signaling molecules, nutrients, even pieces of their own surfaces—in a process known as endocytosis that is essential for learning, memory and basic neural upkeep. Now, new research by Penn State scientists has revealed that this vital process may be governed by a previously unknown molecular gatekeeper: a lattice-like structure just beneath the surface of brain ce…
