Wetting the whistle: neurotropic factor improves salivary function

Abstract

Xerostomia, or dry mouth, is a common side effect of head and neck radiotherapy, Sjögren syndrome, diabetes, old age, and numerous medications. In this issue of the JCI, Xiao and colleagues identified glial cell line–derived neurotrophic factor (GDNF) as a potential stimulus for salivary stem cell growth. Due to its ability to promote neuronal growth, differentiation, and survival, GDNF is currently being used in clinical trials as a treatment for Parkinson disease; therefore, the findings of Xiao and colleagues may initiate a potential treatment for the millions of patients who suffer from xerostomia each year.
