Researchers at Albert Einstein College of Medicine have designed an experimental drug that reversed key symptoms of Alzheimer's disease in mice. The drug works by reinvigorating a cellular cleaning mechanism that gets rid of unwanted proteins by digesting and recycling them. The study was published online today in the journal Cell.

"Discoveries in mice don't always translate to humans, especially in Alzheimer's disease," said co-study leader Ana Maria Cuervo, M.D., Ph.D., the Robert and Renée Belfer Chair for the Study of Neurodegenerative Diseases, professor of developmental and molecular biology, and co-director of the Institute for Aging Research at Einstein.

CMA becomes less efficient as people age, increasing the risk that unwanted proteins will accumulate into insoluble clumps that damage cells. In fact, Alzheimer's and all other neurodegenerative diseases are characterized by the presence of toxic protein aggregates in patients' brains. The Cell paper reveals a dynamic interplay between CMA and Alzheimer's disease, with loss of CMA in neurons contributing to Alzheimer's and vice versa. The findings suggest that drugs for revving up CMA may offer hope for treating neurodegenerative diseases.
