Compounds identified that stabilize retromer protein complex, which protects neurons from amyloid-beta A team of researchers from Columbia University Medical Center (CUMC), Weill Cornell Medical College, and Brandeis University has devised a wholly new approach to the treatment of Alzheimer's disease involving the so-called retromer protein complex. Retromer plays a vital role in neurons, steering amyloid precursor protein (APP) away from a region of the cell where APP is cleaved, creating...

A diametric shift in the levels of two proteins involved in folding, moving and cutting other proteins enables accumulation of the destructive brain plaque found in Alzheimer's disease, researchers report. VPS35 is a protein that folds others into specific positions to unleash their functions. When levels are reduced as they are in aging, it unleashes the normally dormant BACE1, a protein responsible for beta amyloid plaque production, Georgia Health Sciences University researchers report...

Sluggish recycling of a protein-slicing enzyme could promote Alzheimer's disease, according to a study published online on November 21 in The Journal of Cell Biology (www.jcb.org). Abeta, the toxic protein that accumulates in the brains of Alzheimer's patients, is formed when enzymes cut up its parental protein, known as amyloid precursor protein. One of those enzymes is beta-secretase or BACE1. BACE1 cycles between the Golgi apparatus and the plasma membrane, traveling through endosomes...

Parkinson disease (PD) is a devastating incurable disease in which degeneration of dopamine neurons in the brainstem leads to tremors and problems with movement and coordination. An increasing proportion of patients appear to be genetically predisposed to disease. Now, two independent research groups have identified a mutation associated with an inherited form of PD. The papers, published by Cell Press in the July 9 issue of The American Journal of Human Genetics, provide new insight into the...
