Abstract

Intracellular signalling: all in good time Ion channels driven by light have provided electrophysiologists with unprecedented control over the activity state of neurons. Here, Deisseroth and colleagues introduce new molecules that offer a similar level of control over signalling pathways to biochemists. Opsin/GPCR chimaeras were engineered, enabling the authors to modulate G-protein activity via light, which in turn could influence neuronal firing. Expressed in vivo, activating these molecules could drive conditioned place preference in behaving mice.
