New therapeutic target discovered for Alzheimer's disease
27th March 2014
A team of scientists from the University of California, San Diego School of Medicine, the Medical University of South Carolina and San Diego-based American Life Science Pharmaceuticals, Inc., report that cathepsin B gene knockout or its reduction by an enzyme inhibitor blocks creation of key neurotoxic pGlu-Aβ peptides linked to Alzheimer’s disease (AD). Moreover, the candidate inhibitor drug has been shown to be safe in humans.
The findings, based on AD mouse models and published online in the Journal of Alzheimer’s Disease, support continued development of cysteine protease inhibitors as a new drug target class for AD. “No other therapeutic program is investigating cysteine protease inhibitors for treating AD,” said collaborator Vivian Hook, PhD, professor in the UC San Diego Skaggs School of Pharmacy and Pharmaceutical Sciences and in the UC San Diego School of Medicine.
