Brain sensor monitors cytokines

Macquarie University’s Kaixin Zhang and Ewa Goldys have developed a sensor that detects cytokines in the living brain.

The signaling molecules, secreted by glia cells, affect mood, cognition and behavior.

The optical fiber sensor’s surface is treated with a capture protein that monitors the release of cytokine molecules in discrete and targeted parts of the brain.  The goal is to understand cytokine secretion, neural circuits, and how they work together in brain health and disease.
