Protein in the brain could be a key target in controlling Alzheimer’s
A protein recently discovered in the brain could play a key role in regulating the creation of amyloid beta, the major component of plaques implicated in the development of Alzheimer’s disease, according to researchers at Temple University’s School of Medicine.
Alzheimer’s neurons induced from pluripotent stem cells
Led by researchers at the University of California, San Diego School of Medicine, scientists have, for the first time, created stem cell-derived, in vitro models of sporadic and hereditary Alzheimer’s disease (AD), using induced pluripotent stem cells from patients with the much-dreaded neurodegenerative disorder.
Scientists identify protein that contributes to symptoms of Parkinson’s disease
Scientists at the Gladstone Institutes, an independent and nonprofit biomedical-research organization, have identified a protein that exacerbates symptoms of Parkinson’s diseaseĀa discovery that could one day lead to new treatments for people who suffer from this devastating neurodegenerative illness.
Appetite accomplice: Ghrelin receptor alters dopamine signaling
New research reveals a fascinating and unexpected molecular partnership within the brain neurons that regulate appetite. The study, published by Cell Press in the January 26 issue of the journal Neuron, resolves a paradox regarding a receptor without its hormone and may lead to more specific therapeutic interventions for obesity and disorders of dopamine signaling.
