Genetically Encoded Optical Sensors for Monitoring of Intracellular Chloride and Chloride-Selective Channel Activity

This review briefly discusses the main approaches for monitoring chloride (Cl(-)), the most abundant physiological anion. Noninvasive monitoring of intracellular Cl(-) ([Cl(-)]i) is a challenging task owing to two main difficulties: (i) the low transmembrane ratio for Cl(-), approximately 10:1; and (ii) the small driving force for Cl(-), as the Cl(-) reversal potential (E(Cl)) is usually close ...

Monitoring of chloride and activity of glycine receptor channels using genetically encoded fluorescent sensors.

Genetically encoded probes have become powerful tools for non-invasive monitoring of ions, distributions of proteins and the migration and formation of cellular components. We describe the functional expression of two molecular probes for non-invasive fluorescent monitoring of intracellular Cl ([Cl]i) and the functioning of glycine receptor (GlyR) channels. The first probe is a recently develop...

Genetically encoded chloride indicator with improved sensitivity.

Chloride (Cl) is the most abundant physiological anion. Abnormalities in Cl regulation are instrumental in the development of several important diseases including motor disorders and epilepsy. Because of difficulties in the spectroscopic measurement of Cl in live tissues there is little knowledge available regarding the mechanisms of regulation of intracellular Cl concentration. Several years a...

Intracellular potassium and chloride channels: an update.

Channels selective for potassium or chloride ions are present in all intracellular membranes such as mitochondrial membranes, sarcoplasmic/endoplasmic reticulum, nuclear membrane and chromaffin granule membranes. They probably play an important role in events such as acidification of intracellular compartments and regulation of organelle volume. Additionally, intracellular ion channels are targ...

A Genetically Encoded Ratiometric Indicator for Chloride Capturing Chloride Transients in Cultured Hippocampal Neurons

We constructed a novel optical indicator for chloride ions by fusing the chloride-sensitive yellow fluorescent protein with the chloride-insensitive cyan fluorescent protein. The ratio of FRET-dependent emission of these fluorophores varied in proportion to the concentration of Cl and was used to measure intracellular chloride concentration ([Cl-]i) in cultured hippocampal neurons. [Cl-]i decre...
