Alzheimer's risk gene presents potential treatment target

Massachusetts General Hospital (MGH) investigators have determined that one of the recently identified genes contributing to the risk of late-onset Alzheimer's disease regulates the clearance of the toxic amyloid beta (A-beta) protein that accumulates in the brains of patients with the disease. In their report receiving advance online publication in Neuron, the researchers describe a protective variant of the CD33 gene that promotes clearance of A-beta from the brain. They also show that reducing expression of CD33 in immune cells called microglia enhances their ability to clear away A-beta protein, raising the possibility that blocking CD33 activity could help the brain’s immune system remove A-beta.
