abstract = {Fluorescent sensors are an essential part of the
experimental toolbox of the life sciences, where they are
used ubiquitously to visualize intra- and extracellular
signaling. In the brain, optical neurotransmitter sensors
can shed light on temporal and spatial aspects of signal
transmission by directly observing, for instance,
neurotransmitter release and spread. Here we report the
development and application of the first optical sensor for
the amino acid glycine, which is both an inhibitory
neurotransmitter and a co-agonist of the
N-methyl-D-aspartate receptors (NMDARs) involved in synaptic
plasticity. Computational design of a glycine-specific
binding protein allowed us to produce the optical glycine
FRET sensor (GlyFS), which can be used with single and
two-photon excitation fluorescence microscopy. We took
advantage of this newly developed sensor to test predictions
about the uneven spatial distribution of glycine in
extracellular space and to demonstrate that extracellular
glycine levels are controlled by plasticity-inducing
stimuli.},
