A sweet brain preserver: trehalose

It’s sweet, it’s safe, and it looks like it could save neurons. What is it? Trehalose.

This natural sugar is used in the food industry as a preservative and flavor enhancer (it’s in Taco Bell’s meat filling). And curiously, medical researchers keep running into trehalose when they’re looking for ways to fight neurodegenerative diseases.

A recent example from Emory’s Department of Pharmacology: Chris Holler, Thomas Kukar and colleagues were looking for drugs that might boost human cells’ production of progranulin (PGRN), a growth factor that keeps neurons healthy. Mutations in the progranulin gene are a common cause of frontotemporal dementia. Dr. Kukar is a faculty member in the MSP and NS programs.
