First of its kind study may lead to new era of Alzheimer’s drug discovery and therapeutic targets

 

Alzheimer’s disease tragically ravages the brains, memories and ultimately, personalities of its victims. Now affecting 5 million Americans, Alzheimer’s disease is the sixth leading cause of death in the U.S., and a cure for Alzheimer’s remains elusive, as the exact biological events that trigger it are still unknown.

In a new study published today, Arizona State University-Banner Health neuroscientist Salvatore Oddo and his colleagues from Phoenix’s Translational Genomics Research Institute (TGen) — as well as the University of California, Irvine, and Mount Sinai in New York — have identified a new way for brain cells to become fated to die during Alzheimer’s diseases.

The research team has found the first evidence that the activation of a biological pathway called necroptosis, which causes neuronal loss, is closely linked with Alzheimer’s severity, cognitive decline and extreme loss of tissue and brain weight that are all advanced hallmarks of the disease.
