Granulins treasure not trash - potential FTD treatment strategy
Emory University School of Medicine researchers have developed tools that enable them to detect small proteins called granulins for the first time inside cells. Granulins are of interest to neuroscientists because mutations in the granulin gene cause frontotemporal dementia (FTD). However, the functions of granulins were previously unclear.
FTD is an incurable neurodegenerative disease and the most common type of dementia in people younger than 60. Genetic variants in the granulin gene are also a risk factor for Alzheimer’s disease and Parkinson’s disease, suggesting this discovery may have therapeutic potential for a broad spectrum of age-related neurodegenerative diseases.
The results were published August 9 by the journal eNeuro (open access).
