APOE4's Influence on Lipid Droplets in Brain Cells

The largest genetic risk factor for late-onset Alzheimer's disease is apolipoprotein E (APOE), and researchers Sarah Cohen, PhD, and Ian Windham, a former PhD student from the Cohen group, have made a novel discovery about this protein.

Game-Changing Research Shows Astrocytes as Key Regulators of Alzheimer's Disease Progression

Why do some people develop Alzheimer's disease while others don't? And, even more puzzlingly, why do many individuals whose brains are chock-full of toxic amyloid aggregates-;a telltale sign of Alzheimer's brain pathology-;never go on to develop Alzheimer's-associated dementias?

Significance of astrocyte–neuron interactions in fine-tuning brain function

Humans learn to handle a variety of skilled movements throughout their lives, from driving a car to swinging a tennis racket. Neurons are not the only ones who implement this learning, but a new study from The Picower Institute for Learning and Memory at MIT shows that astrocytes play an important role as well.
