A Protective Mechanism Against Neuronal Death in Alzheimer’s

UCLA researchers have uncovered what appears to be a natural protective mechanism against a central cause of neuronal death in Alzheimer’s and similar neurodegenerative diseases. They discovered that a particular enzyme snips apart the abnormal tangles of protein called tau that are associated with cognitive decline and neurodegeneration in Alzheimer’s and similar diseases.

IMPACT:
The study suggests it may be possible to use drugs to enhance that mechanism and alleviate the pathology of Alzheimer’s and similar diseases.

AUTHORS:
Stanislav L. Karsten, Daniel H. Geschwind, and George R. Jackson of the David Geffen School of Medicine at UCLA in Los Angeles, CA; are available for interviews.

JOURNAL:
The research appears as the lead article in the September 7 edition of the peer reviewed Journal Neuron. It is titled “A Genomic Screen for Modifiers of Tauopathy Identifies Puromycin-Sensitive Aminopeptidase as an Inhibitor of Tau-Induced Neurodegeneration.”
