Science Matters: Insights Into Gut-Brain Signaling Raise Hopes For Treating Neurological Disorders

Disruptive innovations sometimes come directly from the development of a novel enabling technology. In other cases, however, they result from focusing on a known problem using a different lens. Such creativity underlies new research suggesting the potential for harnessing the microbiome to treat neurological disorders.

A Dec. 1 paper in Cell offers mechanistic proof of signaling between gut and brain in Parkinson’s Disease (PD). It shows that introducing an altered microbiome from PD patients into...
